BACKGROUND
[0003] Gaming machines which provide players awards in primary or
base games are well known. Gaming machines generally require the
player to place or make a wager to activate the primary or base
game. In many of these gaming machines, the award is based on the
player obtaining a winning symbol or symbol combination and on the
amount of the wager. Generally, symbols or symbol combinations
which are less likely to occur provide higher awards. Secondary or
bonus games are also known in gaming machines. The secondary or
bonus games usually provide an additional award to the player.
SUMMARY
[0004] In certain embodiments, the present disclosure relates to a
gaming system including a processor, and a memory device. The
memory device stores a plurality of instructions, which when
executed by the processor, cause the processor to, for each of a
plurality of non-designated plays of a game of a symbol
accumulation sequence: at each of a plurality of symbol display
positions, cause a display, by a display device, of a symbol
randomly selected from a plurality of different symbols, for each
of the plurality of symbol display positions, responsive to the
displayed symbol being a designated symbol and no designated symbol
being previously accumulated in association with that symbol
display position, accumulate the displayed designated symbol in
association with that symbol display position, for each of the
plurality of symbol display positions, responsive to the displayed
symbol being the designated symbol and another designated symbol
being previously accumulated in association with that symbol
display position, not accumulate the displayed designated symbol in
association with that symbol display position, determine any award
for that non-designated play of the game, and cause a display, by
the display device, of any determined award for that non-designated
play of the game. The instructions, when executed by the processor,
also cause the processor to, for a designated play of the game of
the symbol accumulation sequence: at each of the plurality of
symbol display positions, cause a display, by the display device,
of a symbol randomly selected from the plurality of different
symbols, responsive to at least a first quantity of designated
symbols being accumulated for the plurality of non-designated plays
of the game of the symbol accumulation sequence, modify at least
one parameter of the designated play of the game, determine any
award for the designated play of the game, the determination being
based on the at least one modified parameter of the designated play
of the game, and cause a display, by the display device, of any
determined award for the designated play of the game.
[0005] In certain embodiments, the present disclosure relates to a
method of operating a gaming system including for each of a
plurality of non-designated plays of a game of a symbol
accumulation sequence: at each of a plurality of symbol display
positions, displaying, by a display device, a symbol randomly
selected from a plurality of different symbols, for each of the
plurality of symbol display positions, responsive to the displayed
symbol being a designated symbol and no designated symbol being
previously accumulated in association with that symbol display
position, accumulating, by a processor, the displayed designated
symbol in association with that symbol display position, for each
of the plurality of symbol display positions, responsive to the
displayed symbol being the designated symbol and another designated
symbol being previously accumulated in association with that symbol
display position, not accumulating the displayed designated symbol
in association with that symbol display position, determining, by
the processor, any award for that non-designated play of the game,
and displaying, by the display device, any determined award for
that non-designated play of the game. The method also includes, for
a designated play of the game of the symbol accumulation sequence:
at each of the plurality of symbol display positions, displaying,
by the display device, a symbol randomly selected from the
plurality of different symbols, responsive to at least a first
quantity of designated symbols being accumulated for the plurality
of non-designated plays of the game of the symbol accumulation
sequence, modifying, by the processor, at least one parameter of
the designated play of the game, determining, by the processor, any
award for the designated play of the game, the determination being
based on the at least one modified parameter of the designated play
of the game, and displaying, by the display device, any determined

DETAILED DESCRIPTION
[0012] Awards for Accumulating Symbols
[0013] In various embodiments, the present disclosure relates
generally to gaming systems and methods for providing one or more
awards in association with the accumulation of symbols during a
symbol accumulation sequence including a predefined quantity of
plays of a game. In these embodiments, for each of a first set of
games of the predefined quantity of plays of the game of the symbol
accumulation sequence (e.g., the first game to the next to last
game of the predefined quantity of plays of the game of the symbol
accumulation sequence), the gaming system displays randomly
determined symbols in a plurality of symbol display positions and
accumulates zero, one or more of any designated symbols displayed
in any of the symbol display positions. In these embodiments, for a
second, subsequent set of games of the predefined quantity of plays
of the game of the symbol accumulation sequence (e.g., the last
game of the predefined quantity of plays of the game of the symbol
accumulation sequence), the gaming system employs or otherwise
utilizes any previously accumulated designated symbols displayed in
any of the symbol display positions. In one such embodiment, the
gaming system modifies one or more aspects, components or elements
of one or more designated plays of the game (e.g., the last play of
the game) of the predefined quantity of plays of the game of the
symbol accumulation sequence based on the designated symbols
accumulated during the prior plays of the game of the symbol
accumulation sequence. In another such embodiment, the gaming
system provides the player an additional award or an additional
award opportunity in association with one or more designated plays
of the game (e.g., the last play of the game) of the predefined
quantity of plays of the game of the symbol accumulation sequence
based on the designated symbols accumulated during the prior plays
of the game of the symbol accumulation sequence. In these
embodiments, following such a modification and/or providing of the
additional award/additional award opportunity associated with the
designated play of the game of the predefined quantity of plays of
the game of the symbol accumulation sequence, the gaming system
concludes the symbol accumulation sequence and resets the quantity
of accumulated designated symbols for the next symbol accumulation
sequence including the next predefined quantity of plays of the
game. Such a configuration of enabling a player to play a
predefined quantity of plays of a game to accumulate designated
symbols (which are then used or otherwise redeemed in association
with one or more designated plays of the game of the predefined
quantity of plays of the game) increases the player's anticipation
as more and more symbols are accumulated for the designated play(s)
of the game of the symbol accumulation sequence. Such a
configuration further increases the volatility of the gaming system
by providing that the designated play(s) of the game of the
predefined quantity of plays of the game of the symbol accumulation
sequence is, on average, associated with a greater average expected
payout than any of the other games of the predefined quantity of
plays of the game of the symbol accumulation sequence.
[0014] While certain embodiments described below are directed to a
predefined quantity of primary games, such as primary wagering
games, which form the symbol accumulation sequence, it should be
appreciated that such embodiments may additionally or alternatively
be employed in association with a secondary game, such as a
predefined quantity of bonus games which form the symbol
accumulation sequence. Additionally, while the player's credit
balance, the player's wager, and any awards are displayed as an
amount of monetary credits or currency in certain of the
embodiments described below, one or more of such player's credit
balance, such player's wager, and any awards provided to such a
player may be for non-monetary credits, promotional credits, and/or
player tracking points or credits.
[0015] FIG. 1 is a flowchart of an example process or method of
operating the gaming system of the present disclosure. In various
embodiments, the process is represented by a set of instructions
stored in one or more memories and executed by one or more
processors. Although the process is described with reference to the
flowchart shown in FIG. 1, many other processes of performing the
acts associated with this illustrated process may be employed. For
example, the order of certain of the illustrated blocks or diamonds
may be changed, certain of the illustrated blocks or diamonds may
be optional, or certain of the illustrated blocks or diamonds may
not be employed.
[0016] In various embodiments, the gaming system enables a player
to place a wager amount to play a game as indicated in block 102 of
FIG. 1. In certain embodiments, the gaming system enables a player
to place a wager amount from a plurality of different wager
amounts.
[0017] In association with the placement of the wager amount, the
gaming system determines whether the placed wager triggers a symbol
accumulation sequence including a predefined quantity of plays of a
game as indicated in diamond 104. In these embodiments, the
determination of whether the placed wager triggers a symbol
accumulation sequence (i.e., causes an occurrence of a symbol
accumulation sequence triggering event) is a determination of
whether the wagered on game is part of a predefined quantity of
plays of a game of an existing (i.e., currently employed) symbol
accumulation sequence or whether the wagered on game constitutes
the first play of a predefined quantity of plays of a game of a new
symbol accumulation sequence. Put differently, the gaming system
determines whether the wagered on play of the game is a first
wagered on play of the game since the conclusion of any previous
symbol accumulation sequence and if so, the gaming system
determines that the wagered on play of the game causes the
triggering of another symbol accumulation sequence.
[0018] In certain embodiments, the symbol accumulation triggering
event occurs at regular intervals of quantities of games played.
That is, for every Nth game played, the gaming system determines
that a symbol accumulation sequence triggering event occurs. In one
such embodiment, the interval includes a quantity of games played
at a specific wager amount or wager level, such that the symbol
accumulation triggering event occurs once for every predefined
quantity of games played at that specific wager amount or wager
level. As such, in this embodiment, the gaming system determines
whether the game which the player placed a wager on is the first
game played in the quantity of games played at that wager amount.
For example, an occurrence of a symbol accumulation triggering
event occurs upon the placement of a wager on every tenth game
played at a specific wager amount. In this example, upon the first
game played at a specific wager amount (and the eleventh game
played at that wager amount, and the twenty-first game played at
that wager amount and so on), the gaming system triggers a symbol
accumulation sequence. In another such embodiment, the interval
includes a quantity of games played regardless of the wager amount
or wager level, such that the symbol accumulation triggering event
occurs once for every predefined quantity of games played
independent of the wager amount placed on such games. As such, in
this embodiment, the gaming system determines whether the game
which the player placed a wager on is the first game played in the
quantity of games played at any wager amount.
[0019] If the gaming system determines that the placed wager
triggers a symbol accumulation sequence including a predefined
quantity of plays of a game, the gaming system establishes a game
play counter associated with the symbol accumulation sequence as
indicated in block 106 of FIG. 1.
[0020] As described below, the game play counter tracks the
quantity of games played in association with the triggered symbol
accumulation sequence. In certain embodiments, each different wager
amount is associated with a different game play counter or meter of
a different symbol accumulation sequence. In these embodiments, a
first placed wager amount is associated with a first game play
counter of a first symbol accumulation sequence and a second,
different placed wager amount is associated with a second,
different game play counter of a second, different symbol
accumulation sequence. For example, as seen in FIG. 2A, upon the
initiation of the symbol accumulation sequence following the placed
wager of one-hundred credits, the gaming system establishes a game
play counter or meter 202 associated with the initiated symbol
accumulation sequence. Appropriate messages such as "YOU HAVE TEN
GAMES TO COLLECT AS MANY SPECIAL COLLECTABLE SYMBOLS AS YOU CAN"
may be provided to the player visually, or through suitable audio
or audiovisual displays.
[0021] In certain embodiments, the established game play counter is
associated with tracking a quantity of games played regardless of
the wager amount. In these embodiments, a first placed wager amount
is associated with a first game play counter of a first symbol
accumulation sequence and a second, different placed wager amount
is also associated with the first game play counter of the first
symbol accumulation sequence.
[0022] Following the establishment of a game play counter for the
triggered symbol accumulation sequence or if the gaming system
determines that the placed wager does not cause a triggering of a
symbol accumulation sequence (i.e., the placed wager is for a play
of a game of a predefined quantity of plays of the game of an
existing symbol accumulation sequence), the gaming system
increments the game play counter for the symbol accumulation
sequence as indicated in block 108.
[0023] In certain embodiments in which each different wager amount
is associated with a different game play counter or meter of a
different symbol accumulation sequence, following the placement of
a wager amount on a play of a game (or a qualifying side wager
amount), the gaming system increments the game play counter
associated with the placed wager amount (or the placed qualifying
side wager amount) for the symbol accumulation sequence. For
example, if a wager amount of fifty credits is associated with a
first game play counter of a first symbol accumulation sequence, a
wager amount of one-hundred credits is associated with a second,
different game play counter of a second, different symbol
accumulation sequence and the player places a wager amount of fifty
credits, the gaming system increments the first game play counter
of the first symbol accumulation sequence. In this example, if the
player were to place a wager of one-hundred credits on the play of
the game (or on a subsequent play of the game), the gaming system
increments the second game play counter of the second symbol
accumulation sequence. In certain other embodiments wherein the
game play counter is not associated with different wager amounts,
the gaming system increments the game play counter responsive to
the placement of any wager amount.
[0024] In certain embodiments, the game play counter for an
initiated symbol accumulation sequence is associated with an
electronic gaming machine and/or personal gaming device such that
the game play counter increments for each qualifying wager placed,
regardless of the identity of the player that placed the qualifying
wager. For example, if a first player places a qualifying wager
which results in a game play counter being incremented, that first
player leaves the electronic gaming machine and a second player
subsequently places a qualifying wager at the electronic gaming
machine, the gaming system will increment the game play counter
(such that the second player may realize the benefits of the first
player's wager which caused an increase of the game play counter
for the initiated symbol accumulation sequence). In certain
embodiments, the game play counter for an initiated symbol
accumulation sequence is associated with one or more players
identified via a player tracking system, such that the game play
counter increments for each qualifying wager placed by the one or
more players (and does not increment for qualifying wagers placed
by other players). For example, if a first player places a
qualifying wager which results in a game play counter being
incremented, that first player leaves the electronic gaming machine
and a second player subsequently places a qualifying wager at the
electronic gaming machine, the gaming system will not increment
that game play counter for the second player (but rather will
increment another game play counter for the second player and store
or otherwise maintain the previously incremented game play counter
for the first player).
[0025] Following the increment of the game play counter for the
initiated symbol accumulation sequence, the gaming system
determines, based on the incremented game play counter, whether the
wagered on play of the game is a designated play of the game of the
symbol accumulation sequence as indicated in diamond 110. In this
embodiment, the predefined quantity of plays of the game of the
symbol accumulation sequence includes a first quantity of one or
more non-designated plays of the game and a second quantity of one
or more designated plays of the game, wherein the gaming system
determines, based on the incremented quantity of games of the game
play counter, whether the current game is part of the first
quantity of non-designated plays of the game or the second quantity
of non-designated plays of the game. For example, as seen in FIG.
2A, the predefined quantity of games played for the initiated
symbol accumulation sequence includes ten games, wherein the first
nine games played form the first quantity of non-designated plays
of the game and the tenth game played forms the second quantity of
designated plays of the game.
[0026] If the gaming system determines that the wagered on play of
the game is not a designated play of the game of the symbol
accumulation sequence, the gaming system determines and displays a
plurality of symbols for the wagered on play of the game as
indicated in blocks 112 and 114 of FIG. 1. In these embodiments,
after determining that the first play of the game is part of the
first quantity of non-designated plays of the game (and thus the
current wagered on play of the game is not a designated play of the
game), the gaming system determines the symbols to display from a
plurality of different symbols including one or more designated
symbols. For example, following the spinning of the reels (as seen
in FIG. 2A), the gaming system determined non-designated symbols
204a to 204m and displayed such determined non-designated symbols
at symbol display positions 206a to 206o associated with the
plurality of reels 2154a to 2154e (as seen in FIG. 2B). As also
seen in FIG. 2B, the gaming system also determined designated
symbols 208a and 208b and displayed such determined designated
symbols at symbol display positions 206b and 206h,
respectively.
[0027] After determining and displaying the plurality of symbols
for the play of the game, the gaming system determines and displays
any awards associated with the displayed symbols as indicated in
blocks 116 and 118 of FIG. 1. For example, as seen in FIG. 2B, the
gaming system determines an award of zero credits associated with
the determined and displayed symbols.
[0028] In addition to determining and displaying any award
associated with the displayed symbols, the gaming system determines
whether to accumulate any displayed designated symbol as indicated
in diamond 120 of FIG. 1. In certain embodiments, the gaming system
accumulates designated symbols for each designated symbol displayed
at a symbol display position not otherwise associated with a
previously accumulated designated symbol. In other words, the
gaming system of these embodiments accumulates up to one designated
symbol for each symbol display position.
[0029] If the gaming system determines to accumulate at least one
designated symbol, as indicated in block 122, for each designated
symbol to be accumulated, the gaming system accumulates that
designated symbol in association with the symbol display position
which that designated symbol is displayed at. Following this
accumulation, the gaming system indicates that a designated symbol
has been accumulated in association with that symbol display
position as indicated in block 124. For example, as seen in FIG.
2C, since this play of the game is the first play of the game of
the predefined quantity of plays of the symbol accumulation
sequence (i.e., no designated symbols were previously accumulated
in association with any symbol display positions for this symbol
accumulation sequence), the gaming system accumulates designated
symbols 208a and 208b displayed at symbol display positions 206b
and 206h, respectively and indicates the accumulation of such
designated symbols at such symbol display positions with designated
symbol accumulation indicators 210a and 210b. Appropriate messages
such as "YOU COLLECTED TWO SPECIAL COLLECTABLE SYMBOLS" may be
provided to the player visually, or through suitable audio or
audiovisual displays.
[0030] In certain embodiments, once accumulated in association with
a symbol display position for one play of a game of the predefined
quantity of plays of the game of the symbol accumulation sequence,
the gaming system displays one or more symbols at that same symbol
display position for one or more subsequent plays of the predefined
quantity of plays of the game of the symbol accumulation sequence.
For example, as seen in FIG. 2C, the indication of the accumulated
designated symbols at symbol display positions for the first play
of the game of the predefined quantity of plays of the game of the
symbol accumulation sequence does not prevent other symbols from
subsequently being displayed at symbol display positions for
subsequent plays of the game of the initiated symbol accumulation
sequence. In certain other embodiments, once accumulated in
association with a symbol display position for one play of a game
of the predefined quantity of plays of the game of the symbol
accumulation sequence, the gaming system does not display any other
symbols at that same symbol display position for one or more
subsequent plays of the predefined quantity of plays of the game of
the symbol accumulation sequence. In these embodiments, the
indication of an accumulated designated symbol at a symbol display
position for one play of the game of the predefined quantity of
plays of the game of the symbol accumulation sequence prevents or
otherwise blocks other symbols from subsequently being displayed at
that symbol display position for subsequent plays of the game of
the initiated symbol accumulation sequence.
[0031] Returning to FIG. 1, if the gaming system determines that
the wagered on play of the game is a designated play of the game of
the symbol accumulation sequence, the gaming system modifies one or
more parameters of the wagered on play of the game as indicated in
block 126 of FIG. 1. In certain embodiments, the modified
parameters include assigning one or more wild symbols to one or
more of the symbol display positions associated with previously
accumulated designated symbols. For example, as seen in FIG. 2D,
after eight other games have been played as part of the symbol
accumulation sequence (i.e., game play counter 202 shows that nine
games have been played as part of the symbol accumulation sequence)
and eight other designated symbols have been accumulated during the
symbol accumulation sequence (as indicated by designated symbol
accumulation indicators 210a to 210i), the player places a wager on
the tenth play of the game and the reels being to spin (as seen in
FIG. 2E). In this example, after determining that the tenth play of
the game is part of the second quantity of designated plays of the
game (and thus the current wagered on play of the game is a
designated play of the game), as seen in FIG. 2E, the gaming system
modifies the wagered on play of the game by associating a wild
symbol 212 with each of the symbol display positions associated
with an accumulated designated symbol. That is, the gaming system
modifies the wagered on designated play of the game by modifying
each previously accumulated designated symbol into a wild symbol
for that play of the game. Appropriate messages such as "YOU
COLLECTED TEN SPECIAL COLLECTABLE SYMBOLS OVER YOUR LAST TEN GAMES.
WATCH AS THESE COLLECTED SYMBOLS ARE REDEEMED FOR WILD SYMBOLS FOR
THIS TENTH GAME PLAYED" may be provided to the player visually, or
through suitable audio or audiovisual displays.
[0032] Following the modification of one or more parameters of the
wagered on play of the game, the gaming system determines a
plurality of symbols for the wagered on modified play of the game
as indicated in block 128 of FIG. 1. In this example, zero, one or
more of such determined symbols are based on the modified
parameters of the wagered on designated play of the game. The
gaming system then displays a plurality of symbols for the wagered
on modified play of the game as indicated in block 130 of FIG. 1.
For example, as seen in FIG. 2F, the gaming system determines and
displays wild symbols 212 at the symbol display positions
associated with previously accumulated designated symbols (i.e.,
the symbol displayed positions indicated by designated symbol
accumulation indicators 210a to 210i) and additionally determines
and displays non-designated symbols 204cc to 204gg at the symbol
display positions not associated with previously accumulated
designated symbols.
[0033] After determining and displaying the plurality of symbols
for the wagered on modified play of the game, the gaming system
determines and displays any awards associated with the displayed
symbols as indicated in blocks 132 and 134 of FIG. 1. For example,
as seen in FIG. 2F, the gaming system determines an award of
five-thousand credits associated with the determined and displayed
symbols (including the ten wild symbols 212). Appropriate messages
such as "ALL THOSE COLLECTED SYMBOLS REDEEMED FOR WILD SYMBOLS
RESULTED IN A TOTAL AWARD OF 5000" may be provided to the player
visually, or through suitable audio or audiovisual displays.
[0034] Following the display of any award from the wagered on
modified play of the game (i.e., block 134 of FIG. 1) or following
the indication of one or more designated symbols in association
with one or more symbol display positions (i.e., block 124 of FIG.
1) or following the determination not to accumulate any designated
symbols (i.e., a no determination to diamond 120 of FIG. 1), the
gaming system determines whether the game play counter has reached
the predefined quantity of games for the symbol accumulation
sequence as indicated in diamond 136 of FIG. 1.
[0035] If the game play counter has not reached the predefined
quantity of games for the symbol accumulation sequence, the gaming
system returns to block 102 and enables a player to place a wager
amount to play a game. That is, if at least one game remains to be
played in the predefined quantity of games of the current symbol
accumulation sequence, the gaming system awaits for another wager
to be placed on another play of the game of the predefined quantity
of games of the symbol accumulation sequence.
[0036] On the other hand, if the game play counter has reached the
predefined quantity of games for the symbol accumulation sequence,
the gaming system removes each of any designated symbols
accumulated in association with any of the symbol display positions
and terminates the symbol accumulation sequence as indicated in
blocks 138 and 140. In other words, upon the game play counter
reaching the predefined quantity of games associated with a
termination of the symbol accumulation sequence, the gaming system
resets any previously accumulated designated symbols such that
another triggered symbol accumulation sequence includes the
reaccumulation of zero, one or more designated symbols.
[0037] In certain embodiments, the gaming system enables for the
accumulation of any displayed designated symbols in association
with the designated play of the symbol accumulation sequence. In
certain other embodiments, the gaming system does not enable for
the accumulation of any displayed designated symbols in association
with the designated play of the symbol accumulation sequence.
[0038] It should be appreciated that enabling a player to play a
predefined quantity of plays of a game to accumulate designated
symbols (which are then used or otherwise redeemed in association
with one or more designated plays of the game of the predefined
quantity of plays of the game) increases the player's anticipation
as more and more symbols are accumulated for the designated play(s)
of the game of the symbol accumulation sequence. Such a
configuration further increases the volatility of the gaming system
by providing that the designated play(s) of the game of the
predefined quantity of plays of the game of the symbol accumulation
sequence is, on average, associated with a greater average expected
payout than any of the other games of the predefined quantity of
plays of the game of the symbol accumulation sequence.
[0039] It should be further appreciated that while the game
described herein in the example of FIGS. 2A to 2F is illustrated as
redeeming any accumulated designated symbols as wild symbols for
the designated play of the game of the predefined quantity of plays
of the game of the symbol accumulation sequence, any suitable
feature may additionally or alternatively be activated in
association with the designated play of the game of the predefined
quantity of plays of the game of the symbol accumulation sequence.
In various embodiments, such features that may be activated in
association with the designated play of the game of the predefined
quantity of plays of the game of the symbol accumulation sequence

[0097] In certain embodiments, such as the example embodiment
described above, if the gaming system determines that the wagered
on play of the game is a designated play of the game of the
initiated symbol accumulation sequence, the gaming system modifies
one or more parameters of the wagered on play of the game. In other
embodiments, if the gaming system determines that the wagered on
play of the game is a designated play of the game of the initiated
symbol accumulation sequence, the gaming system provides zero, one
or more additional awards and/or zero, one or more additional award
opportunities to the player. In these embodiments, the amount of
any provided additional awards and/or one or more parameters,
aspects or characteristics of any provided additional award
opportunities is based on the quantity of accumulated designated
symbols.
[0098] In one such embodiment, based on the quantity of accumulated
designated symbols, the gaming system either provides the player no
additional award (i.e., if the quantity of accumulated designated
symbols is less than a first threshold quantity of accumulated
designated symbols), provides the player one of a plurality of
additional awards (i.e., if the quantity of accumulated designated
symbols is greater than a first threshold quantity of accumulated
designated symbols and less than a second threshold quantity of
accumulated designated symbols) or provides the player an
additional award opportunity (i.e., if the quantity of accumulated
designated symbols is greater than a second threshold quantity of
accumulated designated symbols). In this embodiment, if the gaming
system provides an additional award, the value of the provided
additional award is based on the quantity of accumulated designated
symbols, such that the greater the quantity of accumulated
designated symbols, the greater the additional award amount. Also
in this embodiment, if the gaming system provides an additional
award opportunity, the gaming system selects one or more
parameters, aspects or characteristics of the additional award
opportunity based on the quantity of accumulated designated
symbols, such that the greater the quantity of accumulated
designated symbols, the higher average expected payout of the
additional award opportunity which employs the selected parameters,
aspects or characteristics.
[0099] In various embodiments, the gaming system determines zero,
one or more awards (including zero, one or more progressive awards)
to provide to the player in an additional award opportunity wherein
the greater the quantity of accumulated designated symbols, the
greater the probability of winning such awards. In one such example
embodiment, the gaming system employs an additional award generator
to determine any additional awards, wherein the quantity of awards
selected from the additional award generator and/or the quantity of
additional award generations of the additional award generator is
based on the quantity of accumulate designated symbols. For
example, if the gaming system determines that the quantity of
accumulated designated symbols is greater than a second threshold
quantity of accumulated designated symbols, the gaming system
displays an additional award wheel having a plurality of sections
associated with a plurality of awards (including progressive
awards) wherein the quantity of accumulated designated symbols
determines one or more aspects of the use of the additional award
wheel.
[0100] In one example, the gaming system determines the quantity of
pointers or indicators to activate in association with the
additional award generator based on the quantity of accumulated
designated symbols. In this example, the greater the quantity of
accumulated designated symbols, the greater the quantity of
activated pointers (e.g., fifteen accumulated designated symbols is
associated with one activated pointer, sixteen accumulated
designated symbols is associated with two activated pointers and so
on until each of the pointers are activated). In another example,
the gaming system determines the quantity of activations of the
additional award generator based on the quantity of accumulated
designated symbols. In this example, the greater the quantity of
accumulated designated symbols, the greater the quantity of
activations of the additional award generator (e.g., fifteen
accumulated designated symbols is associated with one activation of
the additional award generator, sixteen accumulated designated
symbols is associated with two activations of the additional award
generator and so on). In another example, the gaming system
determines the quantity of pointers or indicators to activate in
association with the additional award generator and the quantity of
activations of the additional award generator based on the quantity
of accumulated designated symbols. In this example, the greater the
quantity of accumulated designated symbols, the greater the
quantity of activated pointers and the greater the quantity of
activations of the additional award generator.
[0101] It should be appreciated that while the additional award
opportunity illustrated in the above-described example includes a
play of a game utilizing an activation of an additional award
generator, any suitable game may be implemented in accordance with
the additional award opportunity disclosed herein. In different
embodiments, such games include, but are not limited to: [0102] i.
a play of any suitable slot game; [0103] ii. a play of any suitable
nudging wild symbol game; [0104] iii. a play of any suitable
expanding wild symbol game; [0105] iv. a play of any suitable wheel
game; [0106] v. a play of any suitable card game; [0107] vi. a play
of any suitable multi-hand card game; [0108] vii. a play of any
suitable offer and acceptance game; [0109] viii. a play of any
suitable award ladder game; [0110] ix. a play of any suitable
puzzle-type game; [0111] x. a play of any suitable persistence
game; [0112] xi. a play of any suitable selection game; [0113] xii.
a play of any suitable cascading symbols game; [0114] xiii. a play
of any suitable ways to win game; [0115] xiv. a play of any
suitable scatter pay game; [0116] xv. a play of any suitable
coin-pusher game; [0117] xvi. a play of any suitable elimination
game; [0118] xvii. a play of any suitable stacked wilds game;
[0119] xviii. a play of any suitable trail game; [0120] xix. a play
of any suitable bingo game; [0121] xx. a play of any suitable video
scratch-off game; [0122] xxi. a play of any suitable
pick-until-complete game; [0123] xxii. a play of any suitable
shooting simulation game; [0124] xxiii. a play of any suitable
racing game; [0125] xxiv. a play of any suitable promotional game;
[0126] xxv. a play of any suitable high-low game; [0127] xxvi. a
play of any suitable lottery game; [0128] xxvii. a play of any
suitable number selection game; [0129] xxviii. a play of any
suitable dice game; [0130] xxix. a play of any suitable skill game;
[0131] xxx. a play of any suitable auction game; [0132] xxxi. a
play of any suitable reverse-auction game; [0133] xxxii. a play of
any suitable group game; [0134] xxxiii. a play of any suitable game
in a service window; [0135] xxxiv. a play of any suitable game on a
mobile device; and/or [0136] xxxv. a play of any suitable game
disclosed herein.
[0137] In certain embodiments, such as the example embodiment
illustrated above, the gaming system accumulates up to one
designated symbol for each symbol display position. In certain
embodiments, the gaming system accumulates up to a set quantity of
designated symbols for each designated symbol displayed at a symbol
display position. In other words, the gaming system of these
embodiments accumulates up to the set quantity of designated
symbols for each symbol display position. In certain embodiments,
the gaming system accumulates designated symbols for each
designated symbol displayed at a symbol display position regardless
of whether or not any other designated symbols were previously
accumulated in association with that symbol display position. In
other words, the gaming system of these embodiments accumulates
each displayed designated symbol for each symbol display position
regardless of any previous accumulations.
[0138] In certain of the above-described embodiments, the placement
of a wager amount on a play of a game constitutes an occurrence of
a game triggering event. In other embodiments wherein the symbol
accumulation sequences includes a predefined quantity of secondary
or bonus games, a game triggering event occurs based on a displayed
event associated with a play of a primary game. In another
embodiment, wherein the symbol accumulation sequences includes a
predefined quantity of secondary or bonus games, the game
triggering event occurs based on an event independent of any
displayed event associated with the play of the primary game. In
other embodiments wherein the symbol accumulation sequence includes
a predefined quantity of plays of a game, a placement of a side
wager in association with a play of the game is an occurrence of a
game triggering event.
[0139] In one embodiment, the gaming system provides a group gaming
aspect to the games disclosed herein. In one such embodiment, the
game is a cooperative community game wherein a plurality of players
cooperate or play together during the symbol accumulation sequence
to win one or more awards. In another such embodiment, the games
disclosed herein a competition community game wherein a plurality
of players compete or player against each other during the symbol
accumulation sequence to win one or more awards.
[0140] In different embodiments, one or more awards provided in
association with the games disclosed herein include one or more of:
a quantity of monetary credits, a quantity of non-monetary credits,
a quantity of promotional credits, a quantity of player tracking
points, a progressive award, a modifier, such as a multiplier, a
quantity of free plays of one or more games, a quantity of plays of
one or more secondary or bonus games, a multiplier of a quantity of
free plays of a game, one or more lottery based awards, such as
lottery or drawing tickets, a wager match for one or more plays of
one or more games, an increase in the average expected payback
percentage for one or more plays of one or more games, one or more
comps, such as a free dinner, a free night's stay at a hotel, a
high value product such as a free car, or a low value product, one
or more bonus credits usable for online play, a lump sum of player
tracking points or credits, a multiplier for player tracking points
or credits, an increase in a membership or player tracking level,
one or more coupons or promotions usable within and/or outside of
the gaming establishment (e.g., a 20% off coupon for use at a
convenience store), virtual goods associated with the gaming
system, virtual goods not associated with the gaming system, an
access code usable to unlock content on an internet.
[0141] In one embodiment, the gaming system causes at least one
display device of an electronic gaming machine ("EGM") to display
the plays of the game of the symbol accumulation sequence. In
another embodiment, in addition or in alternative to each EGM
displaying the plays of the game of the symbol accumulation
sequence, the gaming system causes one or more community or
overhead display devices to display part or all of the plays of the
game of the symbol accumulation sequence to one or more other
players or bystanders either at a gaming establishment or viewing
over a network, such as the internet. In another embodiment, in
addition or in alternative to each EGM displaying the plays of the
game of the symbol accumulation sequence, the gaming system causes
one or more internet sites to each display the plays of the game of
the symbol accumulation sequence such that a player is enabled to
log on from a personal web browser. In another such embodiment, the
gaming system enables the player to play one or more games on one
device while viewing the plays of the game of the symbol
accumulation sequence from another device. For example, the gaming
system enables the player to play one or more games on a mobile
phone while viewing the status of the plays of the game of the
symbol accumulation sequence on a desktop or laptop computer.

[0157] In certain such embodiments, computerized instructions for
controlling any games (such as any primary or base games and/or any
secondary or bonus games) displayed by the EGM (or personal gaming
device) are executed by the central server, central controller, or
remote host. In such "thin client" embodiments, the central server,
central controller, or remote host remotely controls any games (or
other suitable interfaces) displayed by the EGM (or personal gaming
device), and the EGM (or personal gaming device) is utilized to
display such games (or suitable interfaces) and to receive one or
more inputs or commands. In other such embodiments, computerized
instructions for controlling any games displayed by the EGM (or
personal gaming device) are communicated from the central server,
central controller, or remote host to the EGM (or personal gaming
device) and are stored in at least one memory device of the EGM (or
personal gaming device). In such "thick client" embodiments, the at
least one processor of the EGM (or personal gaming device) executes
the computerized instructions to control any games (or other
suitable interfaces) displayed by the EGM (or personal gaming
device).
[0158] In various embodiments in which the gaming system includes a
plurality of EGMs (or personal gaming devices), one or more of the
EGMs (or personal gaming devices) are thin client EGMs (or personal
gaming devices) and one or more of the EGMs (or personal gaming
devices) are thick client EGMs (or personal gaming devices). In
other embodiments in which the gaming system includes one or more
EGMs (or personal gaming devices), certain functions of one or more
of the EGMs (or personal gaming devices) are implemented in a thin
client environment, and certain other functions of one or more of
the EGMs (or personal gaming devices) are implemented in a thick
client environment. In one such embodiment in which the gaming
system includes an EGM (or personal gaming device) and a central
server, central controller, or remote host, computerized
instructions for controlling any primary or base games displayed by
the EGM (or personal gaming device) are communicated from the
central server, central controller, or remote host to the EGM (or
personal gaming device) in a thick client configuration, and
computerized instructions for controlling any secondary or bonus
games or other functions displayed by the EGM (or personal gaming
device) are executed by the central server, central controller, or
remote host in a thin client configuration.
[0159] In certain embodiments in which the gaming system includes:
(a) an EGM (or personal gaming device) configured to communicate
with a central server, central controller, or remote host through a
data network; and/or (b) a plurality of EGMs (or personal gaming
devices) configured to communicate with one another through a data
network, the data network is a local area network (LAN) in which
the EGMs (or personal gaming devices) are located substantially
proximate to one another and/or the central server, central
controller, or remote host. In one example, the EGMs (or personal
gaming devices) and the central server, central controller, or
remote host are located in a gaming establishment or a portion of a
gaming establishment.
[0160] In other embodiments in which the gaming system includes:
(a) an EGM (or personal gaming device) configured to communicate
with a central server, central controller, or remote host through a
data network; and/or (b) a plurality of EGMs (or personal gaming
devices) configured to communicate with one another through a data
network, the data network is a wide area network (WAN) in which one
or more of the EGMs (or personal gaming devices) are not
necessarily located substantially proximate to another one of the
EGMs (or personal gaming devices) and/or the central server,
central controller, or remote host. For example, one or more of the
EGMs (or personal gaming devices) are located: (a) in an area of a
gaming establishment different from an area of the gaming
establishment in which the central server, central controller, or
remote host is located; or (b) in a gaming establishment different
from the gaming establishment in which the central server, central
controller, or remote host is located. In another example, the
central server, central controller, or remote host is not located
within a gaming establishment in which the EGMs (or personal gaming
devices) are located. In certain embodiments in which the data
network is a WAN, the gaming system includes a central server,
central controller, or remote host and an EGM (or personal gaming
device) each located in a different gaming establishment in a same
geographic area, such as a same city or a same state. Gaming
systems in which the data network is a WAN are substantially
identical to gaming systems in which the data network is a LAN,
though the quantity of EGMs (or personal gaming devices) in such
gaming systems may vary relative to one another.
[0161] In further embodiments in which the gaming system includes:
(a) an EGM (or personal gaming device) configured to communicate
with a central server, central controller, or remote host through a
data network; and/or (b) a plurality of EGMs (or personal gaming
devices) configured to communicate with one another through a data
network, the data network is an internet (such as the Internet) or
an intranet. In certain such embodiments, an Internet browser of
the EGM (or personal gaming device) is usable to access an Internet
game page from any location where an Internet connection is
available. In one such embodiment, after the EGM (or personal
gaming device) accesses the Internet game page, the central server,
central controller, or remote host identifies a player before
enabling that player to place any wagers on any plays of any
wagering games. In one example, the central server, central
controller, or remote host identifies the player by requiring a
player account of the player to be logged into via an input of a
unique username and password combination assigned to the player.
The central server, central controller, or remote host may,
however, identify the player in any other suitable manner, such as
by validating a player tracking identification number associated
with the player; by reading a player tracking card or other smart
card inserted into a card reader (as described below); by
validating a unique player identification number associated with
the player by the central server, central controller, or remote
host; or by identifying the EGM (or personal gaming device), such
as by identifying the MAC address or the IP address of the Internet
facilitator. In various embodiments, once the central server,
central controller, or remote host identifies the player, the
central server, central controller, or remote host enables
placement of one or more wagers on one or more plays of one or more
primary or base games and/or one or more secondary or bonus games,
and displays those plays via the Internet browser of the EGM (or
personal gaming device). Examples of implementations of
Internet-based gaming are further described in U.S. Pat. No.
8,764,566, entitled "Internet Remote Game Server," and U.S. Pat.
No. 8,147,334, entitled "Universal Game Server," which are
incorporated herein by reference.
[0162] The central server, central controller, or remote host and
the EGM (or personal gaming device) are configured to connect to
the data network or remote communications link in any suitable
manner. In various embodiments, such a connection is accomplished
via: a conventional phone line or other data transmission line, a
digital subscriber line (DSL), a T-1 line, a coaxial cable, a fiber
optic cable, a wireless or wired routing device, a mobile
communications network connection (such as a cellular network or
mobile Internet network), or any other suitable medium. The
expansion in the quantity of computing devices and the quantity and
speed of Internet connections in recent years increases
opportunities for players to use a variety of EGMs (or personal
gaming devices) to play games from an ever-increasing quantity of
remote sites. Additionally, the enhanced bandwidth of digital
wireless communications may render such technology suitable for
some or all communications, particularly if such communications are
encrypted. Higher data transmission speeds may be useful for
enhancing the sophistication and response of the display and
interaction with players.
EGM Components
[0163] FIG. 3 is a block diagram of an example EGM 1000 and FIGS.
4A and 4B include two different example EGMs 2000a and 2000b. The
EGMs 1000, 2000a, and 2000b are merely example EGMs, and different
EGMs may be implemented using different combinations of the
components shown in the EGMs 1000, 2000a, and 2000b. Although the
below refers to EGMs, in various embodiments personal gaming
devices (such as personal gaming device 2000c of FIG. 4C) may
include some or all of the below components.
[0164] In these embodiments, the EGM 1000 includes a master gaming
controller 1012 configured to communicate with and to operate with
a plurality of peripheral devices 1022.
[0165] The master gaming controller 1012 includes at least one
processor 1010. The at least one processor 1010 is any suitable
processing device or set of processing devices, such as a
microprocessor, a microcontroller-based platform, a suitable
integrated circuit, or one or more application-specific integrated
circuits (ASICs), configured to execute software enabling various
configuration and reconfiguration tasks, such as: (1) communicating
with a remote source (such as a server that stores authentication
information or game information) via a communication interface 1006
of the master gaming controller 1012; (2) converting signals read
by an interface to a format corresponding to that used by software
or memory of the EGM; (3) accessing memory to configure or
reconfigure game parameters in the memory according to indicia read
from the EGM; (4) communicating with interfaces and the peripheral
devices 1022 (such as input/output devices); and/or (5) controlling
the peripheral devices 1022. In certain embodiments, one or more
components of the master gaming controller 1012 (such as the at
least one processor 1010) reside within a housing of the EGM
(described below), while in other embodiments at least one
component of the master gaming controller 1012 resides outside of
the housing of the EGM.
[0166] The master gaming controller 1012 also includes at least one
memory device 1016, which includes: (1) volatile memory (e.g., RAM
1009, which can include non-volatile RAM, magnetic RAM,
ferroelectric RAM, and any other suitable forms); (2) non-volatile
memory 1019 (e.g., disk memory, FLASH memory, EPROMs, EEPROMs,
memristor-based non-volatile solid-state memory, etc.); (3)
unalterable memory (e.g., EPROMs 1008); (4) read-only memory;
and/or (5) a secondary memory storage device 1015, such as a
non-volatile memory device, configured to store gaming software
related information (the gaming software related information and
the memory may be used to store various audio files and games not
currently being used and invoked in a configuration or
reconfiguration). Any other suitable magnetic, optical, and/or
semiconductor memory may operate in conjunction with the EGM
disclosed herein. In certain embodiments, the at least one memory
device 1016 resides within the housing of the EGM (described
below), while in other embodiments at least one component of the at
least one memory device 1016 resides outside of the housing of the
EGM.
[0167] The at least one memory device 1016 is configured to store,
for example: (1) configuration software 1014, such as all the
parameters and settings for a game playable on the EGM; (2)
associations 1018 between configuration indicia read from an EGM
with one or more parameters and settings; (3) communication
protocols configured to enable the at least one processor 1010 to
communicate with the peripheral devices 1022; and/or (4)
communication transport protocols (such as TCP/IP, USB, Firewire,
IEEE1394, Bluetooth, IEEE 802.11x (IEEE 802.11 standards),
hiperlan/2, HomeRF, etc.) configured to enable the EGM to
communicate with local and non-local devices using such protocols.
In one implementation, the master gaming controller 1012
communicates with other devices using a serial communication
protocol. A few non-limiting examples of serial communication
protocols that other devices, such as peripherals (e.g., a bill
validator or a ticket printer), may use to communicate with the
master game controller 1012 include USB, RS-232, and Netplex (a
proprietary protocol developed by IGT).
[0168] In certain embodiments, the at least one memory device 1016
is configured to store program code and instructions executable by
the at least one processor of the EGM to control the EGM. The at
least one memory device 1016 of the EGM also stores other operating
data, such as image data, event data, input data, random number
generators (RNGs) or pseudo-RNGs, paytable data or information,
and/or applicable game rules that relate to the play of one or more
games on the EGM. In various embodiments, part or all of the
program code and/or the operating data described above is stored in
at least one detachable or removable memory device including, but
not limited to, a cartridge, a disk, a CD ROM, a DVD, a USB memory
device, or any other suitable non-transitory computer readable
medium. In certain such embodiments, an operator (such as a gaming
establishment operator) and/or a player uses such a removable
memory device in an EGM to implement at least part of the present
disclosure. In other embodiments, part or all of the program code
and/or the operating data is downloaded to the at least one memory
device of the EGM through any suitable data network described above
(such as an Internet or intranet).
[0169] The at least one memory device 1016 also stores a plurality
of device drivers 1042. Examples of different types of device
drivers include device drivers for EGM components and device
drivers for the peripheral components 1022. Typically, the device
drivers 1042 utilize various communication protocols that enable
communication with a particular physical device. The device driver
abstracts the hardware implementation of that device. For example,
a device driver may be written for each type of card reader that
could potentially be connected to the EGM. Non-limiting examples of
communication protocols used to implement the device drivers
include Netplex, USB, Serial, Ethernet 175, Firewire, I/O
debouncer, direct memory map, serial, PCI, parallel, RF,
Bluetooth.TM., near-field communications (e.g., using near-field
magnetics), 802.11 (WiFi), etc. In one embodiment, when one type of
a particular device is exchanged for another type of the particular
device, the at least one processor of the EGM loads the new device
driver from the at least one memory device to enable communication
with the new device. For instance, one type of card reader in the
EGM can be replaced with a second different type of card reader
when device drivers for both card readers are stored in the at
least one memory device.
[0170] In certain embodiments, the software units stored in the at
least one memory device 1016 can be upgraded as needed. For
instance, when the at least one memory device 1016 is a hard drive,
new games, new game options, new parameters, new settings for
existing parameters, new settings for new parameters, new device
drivers, and new communication protocols can be uploaded to the at
least one memory device 1016 from the master game controller 1012
or from some other external device. As another example, when the at
least one memory device 1016 includes a CD/DVD drive including a
CD/DVD configured to store game options, parameters, and settings,
the software stored in the at least one memory device 1016 can be
upgraded by replacing a first CD/DVD with a second CD/DVD. In yet
another example, when the at least one memory device 1016 uses
flash memory 1019 or EPROM 1008 units configured to store games,
game options, parameters, and settings, the software stored in the
flash and/or EPROM memory units can be upgraded by replacing one or
more memory units with new memory units that include the upgraded
software. In another embodiment, one or more of the memory devices,
such as the hard drive, may be employed in a game software download
process from a remote software server.
[0171] In some embodiments, the at least one memory device 1016
also stores authentication and/or validation components 1044
configured to authenticate/validate specified EGM components and/or
information, such as hardware components, software components,
firmware components, peripheral device components, user input
device components, information received from one or more user input
devices, information stored in the at least one memory device 1016,
etc. Examples of various authentication and/or validation
components are described in U.S. Pat. No. 6,620,047, entitled
"Electronic Gaming Apparatus Having Authentication Data Sets,"
which is incorporated herein by reference.
[0172] In certain embodiments, the peripheral devices 1022 include

on a display device of the EGM (described below) that is actuatable
via a touch screen of the EGM (described below) or via use of a
suitable input device of the EGM (such as a mouse or a joystick).
One such wagering or betting device is as a maximum wager or bet
device that, when actuated, causes the EGM to place a maximum wager
on a play of a game. Another such wagering or betting device is a
repeat bet device that, when actuated, causes the EGM to place a
wager that is equal to the previously-placed wager on a play of a
game. A further such wagering or betting device is a bet one device
that, when actuated, causes the EGM to increase the wager by one
credit. Generally, upon actuation of one of the wagering or betting
devices, the quantity of credits displayed in a credit meter
(described below) decreases by the amount of credits wagered, while
the quantity of credits displayed in a bet display (described
below) increases by the amount of credits wagered.
[0184] In various embodiments, the at least one input device 1030
includes at least one game play activation device. In various
embodiments, the one or more game play initiation devices are each:
(1) a mechanical button supported by the housing of the EGM (such

on a display device of the EGM (described below) that is actuatable
via a touch screen of the EGM (described below) or via use of a
suitable input device of the EGM (such as a mouse or a joystick).
After a player appropriately funds the EGM and places a wager, the
EGM activates the game play activation device to enable the player
to actuate the game play activation device to initiate a play of a
game on the EGM (or another suitable sequence of events associated
with the EGM). After the EGM receives an actuation of the game play
activation device, the EGM initiates the play of the game. The
example EGMs 2000a and 2000b illustrated in FIGS. 4A and 4B each
include a game play activation device in the form of a game play
initiation button 2132. In other embodiments, the EGM begins game
play automatically upon appropriate funding rather than upon

U.S. Pat. No. 7,290,072 describes a variety of EGMs including one
or more communication ports that enable the EGMs to communicate and
operate with one or more external peripherals.
[0199] As generally described above, in certain embodiments, such
as the example EGMs 2000a and 2000b illustrated in FIGS. 4A and 4B,
the EGM has a support structure, housing, or cabinet that provides
support for a plurality of the input devices and the output devices
of the EGM. Further, the EGM is configured such that a player may
operate it while standing or sitting. In various embodiments, the
EGM is positioned on a base or stand, or is configured as a
pub-style tabletop game (not shown) that a player may operate
typically while sitting. As illustrated by the different example
EGMs 2000a and 2000b shown in FIGS. 4A and 4B, EGMs may have
varying housing and display configurations.
[0200] In certain embodiments, the EGM is a device that has
obtained approval from a regulatory gaming commission, and in other
embodiments, the EGM is a device that has not obtained approval
from a regulatory gaming commission.
[0201] The EGMs described above are merely three examples of
different types of EGMs. Certain of these example EGMs may include
one or more elements that may not be included in all gaming
systems, and these example EGMs may not include one or more
elements that are included in other gaming systems. For example,
certain EGMs include a coin acceptor while others do not.
Operation of Primary or Base Games and/or Secondary or Bonus
Games
[0202] In various embodiments, an EGM may be implemented in one of
a variety of different configurations. In various embodiments, the
EGM may be implemented as one of: (a) a dedicated EGM in which
computerized game programs executable by the EGM for controlling
any primary or base games (referred to herein as "primary games")
and/or any secondary or bonus games or other functions (referred to
herein as "secondary games") displayed by the EGM are provided with
the EGM before delivery to a gaming establishment or before being
provided to a player; and (b) a changeable EGM in which
computerized game programs executable by the EGM for controlling
any primary games and/or secondary games displayed by the EGM are
downloadable or otherwise transferred to the EGM through a data
network or remote communication link; from a USB drive, flash
memory card, or other suitable memory device; or in any other
suitable manner after the EGM is physically located in a gaming
establishment or after the EGM is provided to a player.
[0203] As generally explained above, in various embodiments in
which the gaming system includes a central server, central
controller, or remote host and a changeable EGM, the at least one
memory device of the central server, central controller, or remote
host stores different game programs and instructions executable by
the at least one processor of the changeable EGM to control one or
more primary games and/or secondary games displayed by the
changeable EGM. More specifically, each such executable game
program represents a different game or a different type of game
that the at least one changeable EGM is configured to operate. In
one example, certain of the game programs are executable by the
changeable EGM to operate games having the same or substantially
the same game play but different paytables. In different
embodiments, each executable game program is associated with a
primary game, a secondary game, or both. In certain embodiments, an
executable game program is executable by the at least one processor
of the at least one changeable EGM as a secondary game to be played
simultaneously with a play of a primary game (which may be
downloaded to or otherwise stored on the at least one changeable
EGM), or vice versa.
[0204] In operation of such embodiments, the central server,
central controller, or remote host is configured to communicate one
or more of the stored executable game programs to the at least one
processor of the changeable EGM. In different embodiments, a stored
executable game program is communicated or delivered to the at
least one processor of the changeable EGM by: (a) embedding the
executable game program in a device or a component (such as a
microchip to be inserted into the changeable EGM); (b) writing the
executable game program onto a disc or other media; or (c)
uploading or streaming the executable game program over a data
network (such as a dedicated data network). After the executable
game program is communicated from the central server, central
controller, or remote host to the changeable EGM, the at least one
processor of the changeable EGM executes the executable game
program to enable the primary game and/or the secondary game
associated with that executable game program to be played using the
display device(s) and/or the input device(s) of the changeable EGM.
That is, when an executable game program is communicated to the at
least one processor of the changeable EGM, the at least one
processor of the changeable EGM changes the game or the type of
game that may be played using the changeable EGM.
[0205] In certain embodiments, the gaming system randomly
determines any game outcome(s) (such as a win outcome) and/or
award(s) (such as a quantity of credits to award for the win
outcome) for a play of a primary game and/or a play of a secondary
game based on probability data. In certain such embodiments, this
random determination is provided through utilization of an RNG,
such as a true RNG or a pseudo RNG, or any other suitable
randomization process. In one such embodiment, each game outcome or
award is associated with a probability, and the gaming system
generates the game outcome(s) and/or the award(s) to be provided
based on the associated probabilities. In these embodiments, since
the gaming system generates game outcomes and/or awards randomly or
based on one or more probability calculations, there is no
certainty that the gaming system will ever provide any specific
game outcome and/or award.
[0206] In certain embodiments, the gaming system maintains one or
more predetermined pools or sets of predetermined game outcomes
and/or awards. In certain such embodiments, upon generation or
receipt of a game outcome and/or award request, the gaming system
independently selects one of the predetermined game outcomes and/or
awards from the one or more pools or sets. The gaming system flags
or marks the selected game outcome and/or award as used. Once a
game outcome or an award is flagged as used, it is prevented from
further selection from its respective pool or set; that is, the
gaming system does not select that game outcome or award upon
another game outcome and/or award request. The gaming system
provides the selected game outcome and/or award. Examples of this
type of award evaluation are described in U.S. Pat. No. 7,470,183,
entitled "Finite Pool Gaming Method and Apparatus"; U.S. Pat. No.
7,563,163, entitled "Gaming Device Including Outcome Pools for
Providing Game Outcomes"; U.S. Pat. No. 7,833,092, entitled "Method
and System for Compensating for Player Choice in a Game of Chance";
U.S. Pat. No. 8,070,579, entitled "Bingo System with Downloadable
Common Patterns"; and U.S. Pat. No. 8,398,472, entitled "Central
Determination Poker Game," which are incorporated herein by
reference.
[0207] In certain embodiments, the gaming system determines a
predetermined game outcome and/or award based on the results of a
bingo, keno, or lottery game. In certain such embodiments, the
gaming system utilizes one or more bingo, keno, or lottery games to
determine the predetermined game outcome and/or award provided for
a primary game and/or a secondary game. The gaming system is
provided or associated with a bingo card. Each bingo card consists
of a matrix or array of elements, wherein each element is
designated with separate indicia. After a bingo card is provided,
the gaming system randomly selects or draws a plurality of the
elements. As each element is selected, a determination is made as
to whether the selected element is present on the bingo card. If
the selected element is present on the bingo card, that selected
element on the provided bingo card is marked or flagged. This
process of selecting elements and marking any selected elements on
the provided bingo cards continues until one or more predetermined
patterns are marked on one or more of the provided bingo cards.
After one or more predetermined patterns are marked on one or more
of the provided bingo cards, game outcome and/or award is
determined based, at least in part, on the selected elements on the
provided bingo cards. Examples of this type of award determination
are described in U.S. Pat. No. 7,753,774, entitled "Using Multiple
Bingo Cards to Represent Multiple Slot Paylines and Other Class III
Game Options"; U.S. Pat. No. 7,731,581, entitled "Multi-Player
Bingo Game with Multiple Alternative Outcome Displays"; U.S. Pat.
No. 7,955,170, entitled "Providing Non-Bingo Outcomes for a Bingo
Game"; U.S. Pat. No. 8,070,579, entitled "Bingo System with
Downloadable Common Patterns"; and U.S. Pat. No. 8,500,538,
entitled "Bingo Gaming System and Method for Providing Multiple
Outcomes from Single Bingo Pattern," which are incorporated herein
by reference.
[0208] In certain embodiments in which the gaming system includes a
central server, central controller, or remote host and an EGM, the
EGM is configured to communicate with the central server, central
controller, or remote host for monitoring purposes only. In such
embodiments, the EGM determines the game outcome(s) and/or award(s)
to be provided in any of the manners described above, and the
central server, central controller, or remote host monitors the
activities and events occurring on the EGM. In one such embodiment,
the gaming system includes a real-time or online accounting and
gaming information system configured to communicate with the
central server, central controller, or remote host. In this
embodiment, the accounting and gaming information system includes:
(a) a player database configured to store player profiles, (b) a
player tracking module configured to track players (as described
below), and (c) a credit system configured to provide automated
transactions. Examples of such accounting systems are described in
U.S. Pat. No. 6,913,534, entitled "Gaming Machine Having a Lottery
Game and Capability for Integration with Gaming Device Accounting
System and Player Tracking System," and U.S. Pat. No. 8,597,116,
entitled "Virtual Player Tracking and Related Services," which are
incorporated herein by reference.
[0209] As noted above, in various embodiments, the gaming system
includes one or more executable game programs executable by at
least one processor of the gaming system to provide one or more
primary games and one or more secondary games. The primary game(s)
and the secondary game(s) may comprise any suitable games and/or
wagering games, such as, but not limited to: electro-mechanical or
video slot or spinning reel type games; video card games such as
video draw poker, multi-hand video draw poker, other video poker
games, video blackjack games, and video baccarat games; video keno
games; video bingo games; and video selection games.
[0210] In certain embodiments in which the primary game is a slot
or spinning reel type game, the gaming system includes one or more
reels in either an electromechanical form with mechanical rotating
reels or in a video form with simulated reels and movement thereof.
Each reel displays a plurality of indicia or symbols, such as
bells, hearts, fruits, numbers, letters, bars, or other images that
typically correspond to a theme associated with the gaming system.
In certain such embodiments, the gaming system includes one or more
paylines associated with the reels. The example EGM 2000b shown in
FIG. 4B includes a payline 1152 and a plurality of reels 1154. In
certain embodiments, one or more of the reels are independent reels
or unisymbol reels. In such embodiments, each independent reel
generates and displays one symbol.
[0211] In various embodiments, one or more of the paylines is
horizontal, vertical, circular, diagonal, angled, or any suitable
combination thereof. In other embodiments, each of one or more of
the paylines is associated with a plurality of adjacent symbol
display areas on a requisite number of adjacent reels. In one such
embodiment, one or more paylines are formed between at least two
symbol display areas that are adjacent to each other by either
sharing a common side or sharing a common corner (i.e., such
paylines are connected paylines). The gaming system enables a wager
to be placed on one or more of such paylines to activate such
paylines. In other embodiments in which one or more paylines are
formed between at least two adjacent symbol display areas, the
gaming system enables a wager to be placed on a plurality of symbol
display areas, which activates those symbol display areas.
[0212] In various embodiments, the gaming system provides one or
more awards after a spin of the reels when specified types and/or
configurations of the indicia or symbols on the reels occur on an
active payline or otherwise occur in a winning pattern, occur on
the requisite number of adjacent reels, and/or occur in a scatter
pay arrangement.
[0213] In certain embodiments, the gaming system employs a ways to
win award determination. In these embodiments, any outcome to be
provided is determined based on a number of associated symbols that
are generated in active symbol display areas on the requisite
number of adjacent reels (i.e., not on paylines passing through any
displayed winning symbol combinations). If a winning symbol
combination is generated on the reels, one award for that
occurrence of the generated winning symbol combination is provided.
Examples of ways to win award determinations are described in U.S.
Pat. No. 8,012,011, entitled "Gaming Device and Method Having
Independent Reels and Multiple Ways of Winning"; U.S. Pat. No.
8,241,104, entitled "Gaming Device and Method Having Designated
Rules for Determining Ways To Win"; and U.S. Pat. No. 8,430,739,
entitled "Gaming System and Method Having Wager Dependent Different
Symbol Evaluations," which are incorporated herein by
reference.
[0214] In various embodiments, the gaming system includes a
progressive award. Typically, a progressive award includes an
initial amount and an additional amount funded through a portion of
each wager placed to initiate a play of a primary game. When one or
more triggering events occurs, the gaming system provides at least
a portion of the progressive award. After the gaming system
provides the progressive award, an amount of the progressive award
is reset to the initial amount and a portion of each subsequent
wager is allocated to the next progressive award. Examples of
progressive gaming systems are described in U.S. Pat. No.
7,585,223, entitled "Server Based Gaming System Having Multiple
Progressive Awards"; U.S. Pat. No. 7,651,392, entitled "Gaming
Device System Having Partial Progressive Payout"; U.S. Pat. No.
7,666,093, entitled "Gaming Method and Device Involving Progressive
Wagers"; U.S. Pat. No. 7,780,523, entitled "Server Based Gaming
System Having Multiple Progressive Awards"; and U.S. Pat. No.
8,337,298, entitled "Gaming Device Having Multiple Different Types
of Progressive Awards," which are incorporated herein by
reference
[0215] As generally noted above, in addition to providing winning
credits or other awards for one or more plays of the primary
game(s), in various embodiments the gaming system provides credits
or other awards for one or more plays of one or more secondary
games. The secondary game typically enables an award to be obtained
addition to any award obtained through play of the primary game(s).
The secondary game(s) typically produces a higher level of player
excitement than the primary game(s) because the secondary game(s)
provides a greater expectation of winning than the primary game(s)
and is accompanied with more attractive or unusual features than
the primary game(s). The secondary game(s) may be any type of
suitable game, either similar to or completely different from the
primary game.
[0216] In various embodiments, the gaming system automatically
provides or initiates the secondary game upon the occurrence of a
triggering event or the satisfaction of a qualifying condition. In
other embodiments, the gaming system initiates the secondary game
upon the occurrence of the triggering event or the satisfaction of
the qualifying condition and upon receipt of an initiation input.
In certain embodiments, the triggering event or qualifying
condition is a selected outcome in the primary game(s) or a
particular arrangement of one or more indicia on a display device
for a play of the primary game(s), such as a "BONUS" symbol
appearing on three adjacent reels along a payline following a spin
of the reels for a play of the primary game. In other embodiments,
the triggering event or qualifying condition occurs based on a
certain amount of game play (such as number of games, number of
credits, amount of time) being exceeded, or based on a specified
number of points being earned during game play. Any suitable
triggering event or qualifying condition or any suitable
combination of a plurality of different triggering events or
qualifying conditions may be employed.
[0217] In other embodiments, at least one processor of the gaming
system randomly determines when to provide one or more plays of one
or more secondary games. In one such embodiment, no apparent reason
is provided for providing the secondary game. In this embodiment,
qualifying for a secondary game is not triggered by the occurrence
of an event in any primary game or based specifically on any of the
plays of any primary game. That is, qualification is provided
without any explanation or, alternatively, with a simple
explanation. In another such embodiment, the gaming system
determines qualification for a secondary game at least partially
based on a game triggered or symbol triggered event, such as at
least partially based on play of a primary game.
[0218] In various embodiments, after qualification for a secondary
game has been determined, the secondary game participation may be
enhanced through continued play on the primary game. Thus, in
certain embodiments, for each secondary game qualifying event, such
as a secondary game symbol, that is obtained, a given number of
secondary game wagering points or credits is accumulated in a
"secondary game meter" configured to accrue the secondary game
wagering credits or entries toward eventual participation in the
secondary game. In one such embodiment, the occurrence of multiple
such secondary game qualifying events in the primary game results
in an arithmetic or exponential increase in the number of secondary
game wagering credits awarded. In another such embodiment, any
extra secondary game wagering credits may be redeemed during the
secondary game to extend play of the secondary game.
[0219] In certain embodiments, no separate entry fee or buy-in for
the secondary game is required. That is, entry into the secondary
game cannot be purchased; rather, in these embodiments entry must
be won or earned through play of the primary game, thereby
encouraging play of the primary game. In other embodiments,
qualification for the secondary game is accomplished through a
simple "buy-in." For example, qualification through other specified
activities is unsuccessful, payment of a fee or placement of an
additional wager "buys-in" to the secondary game. In certain
embodiments, a separate side wager must be placed on the secondary
game or a wager of a designated amount must be placed on the
primary game to enable qualification for the secondary game. In
these embodiments, the secondary game triggering event must occur
and the side wager (or designated primary game wager amount) must
have been placed for the secondary game to trigger.
[0220] In various embodiments in which the gaming system includes a
plurality of EGMs, the EGMs are configured to communicate with one
another to provide a group gaming environment. In certain such
embodiments, the EGMs enable players of those EGMs to work in
conjunction with one another, such as by enabling the players to
play together as a team or group, to win one or more awards. In
other such embodiments, the EGMs enable players of those EGMs to
compete against one another for one or more awards. In one such
embodiment, the EGMs enable the players of those EGMs to
participate in one or more gaming tournaments for one or more
awards. Examples of group gaming systems are described in U.S. Pat.
No. 8,070,583, entitled "Server Based Gaming System and Method for
Selectively Providing One or More Different Tournaments"; U.S. Pat.
No. 8,500,548, entitled "Gaming System and Method for Providing
Team Progressive Awards"; and U.S. Pat. No. 8,562,423, entitled
"Method and Apparatus for Rewarding Multiple Game Players for a
Single Win," which are incorporated herein by reference.
[0221] In various embodiments, the gaming system includes one or
more player tracking systems. Such player tracking systems enable
operators of the gaming system (such as casinos or other gaming
establishments) to recognize the value of customer loyalty by
identifying frequent customers and rewarding them for their
patronage. Such a player tracking system is configured to track a
player's gaming activity. In one such embodiment, the player
tracking system does so through the use of player tracking cards.
In this embodiment, a player is issued a player identification card
that has an encoded player identification number that uniquely
identifies the player. When the player's playing tracking card is
inserted into a card reader of the gaming system to begin a gaming
session, the card reader reads the player identification number off
the player tracking card to identify the player. The gaming system
timely tracks any suitable information or data relating to the
identified player's gaming session. The gaming system also timely
tracks when the player tracking card is removed to conclude play
for that gaming session. In another embodiment, rather than
requiring insertion of a player tracking card into the card reader,
the gaming system utilizes one or more portable devices, such as a
mobile phone, a radio frequency identification tag, or any other
suitable wireless device, to track when a gaming session begins and
ends. In another embodiment, the gaming system utilizes any
suitable biometric technology or ticket technology to track when a
gaming session begins and ends.
[0222] In such embodiments, during one or more gaming sessions, the
gaming system tracks any suitable information or data, such as any
amounts wagered, average wager amounts, and/or the time at which
these wagers are placed. In different embodiments, for one or more
players, the player tracking system includes the player's account
number, the player's card number, the player's first name, the
player's surname, the player's preferred name, the player's player
tracking ranking, any promotion status associated with the player's
player tracking card, the player's address, the player's birthday,
the player's anniversary, the player's recent gaming sessions, or
any other suitable data. In various embodiments, such tracked
information and/or any suitable feature associated with the player
tracking system is displayed on a player tracking display. In
various embodiments, such tracked information and/or any suitable
feature associated with the player tracking system is displayed via
one or more service windows that are displayed on the central
display device and/or the upper display device. Examples of player
tracking systems are described in U.S. Pat. No. 6,722,985, entitled
"Universal Player Tracking System"; U.S. Pat. No. 6,908,387,
entitled "Player Tracking Communication Mechanisms in a Gaming
Machine"; U.S. Pat. No. 7,311,605, entitled "Player Tracking
Assembly for Complete Patron Tracking for Both Gaming and
Non-Gaming Casino Activity"; U.S. Pat. No. 7,611,411, entitled
"Player Tracking Instruments Having Multiple Communication Modes";
U.S. Pat. No. 7,617,151, entitled "Alternative Player Tracking
Techniques"; and U.S. Pat. No. 8,057,298, entitled "Virtual Player
Tracking and Related Services," which are incorporated herein by
reference.
Web-Based Gaming
[0223] In various embodiments, the gaming system includes one or
more servers configured to communicate with a personal gaming
device--such as a smartphone, a tablet computer, a desktop
computer, or a laptop computer--to enable web-based game play using
the personal gaming device. In various embodiments, the player must
first access a gaming website via an Internet browser of the
personal gaming device or execute an application (commonly called
an "app") installed on the personal gaming device before the player
can use the personal gaming device to participate in web-based game
play. In certain embodiments, the one or more servers and the
personal gaming device operate in a thin-client environment. In
these embodiments, the personal gaming device receives inputs via
one or more input devices (such as a touch screen and/or physical
buttons), the personal gaming device sends the received inputs to
the one or more servers, the one or more servers make various
determinations based on the inputs and determine content to be
displayed (such as a randomly determined game outcome and
corresponding award), the one or more servers send the content to
the personal gaming device, and the personal gaming device displays
the content.
[0224] In certain such embodiments, the one or more servers must
identify the player before enabling game play on the personal
gaming device (or, in some embodiments, before enabling monetary
wager-based game play on the personal gaming device). In these
embodiments, the player must identify herself to the one or more
servers, such as by inputting the player's unique username and
password combination, providing an input to a biometric sensor
(e.g., a fingerprint sensor, a retinal sensor, a voice sensor, or a
facial-recognition sensor), or providing any other suitable
information.
[0225] Once identified, the one or more servers enable the player
to establish an account balance from which the player can draw
credits usable to wager on plays of a game. In certain embodiments,
the one or more servers enable the player to initiate an electronic
funds transfer to transfer funds from a bank account to the
player's account balance. In other embodiments, the one or more
servers enable the player to make a payment using the player's
credit card, debit card, or other suitable device to add money to
the player's account balance. In other embodiments, the one or more
servers enable the player to add money to the player's account
balance via a peer-to-peer type application, such as PayPal or
Venmo. The one or more servers also enable the player to cash out
the player's account balance (or part of it) in any suitable
manner, such as via an electronic funds transfer, by initiating
creation of a paper check that is mailed to the player, or by
initiating printing of a voucher at a kiosk in a gaming
establishment.
[0226] In certain embodiments, the one or more servers include a
payment server that handles establishing and cashing out players'
account balances and a separate game server configured to determine
the outcome and any associated award for a play of a game. In these
embodiments, the game server is configured to communicate with the
personal gaming device and the payment device, and the personal
gaming device and the payment device are not configured to directly
communicate with one another. In these embodiments, when the game
server receives data representing a request to start a play of a
game at a desired wager, the game server sends data representing
the desired wager to the payment server. The payment server
determines whether the player's account balance can cover the
desired wager (i.e., includes a monetary balance at least equal to
the desired wager).
[0227] If the payment server determines that the player's account
balance cannot cover the desired wager, the payment server notifies
the game server, which then instructs the personal gaming device to
display a suitable notification to the player that the player's
account balance is too low to place the desired wager. If the
payment server determines that the player's account balance can
cover the desired wager, the payment server deducts the desired
wager from the account balance and notifies the game server. The
game server then determines an outcome and any associated award for
the play of the game. The game server notifies the payment server
of any nonzero award, and the payment server increases the player's
account balance by the nonzero award. The game server sends data
representing the outcome and any award to the personal gaming
device, which displays the outcome and any award.
[0228] In certain embodiments, the one or more servers enable
web-based game play using a personal gaming device only if the
personal gaming device satisfies one or more jurisdictional
requirements. In one embodiment, the one or more servers enable
web-based game play using the personal gaming device only if the
personal gaming device is located within a designated geographic
area (such as within certain state or county lines or within the
boundaries of a gaming establishment). In this embodiment, the
geolocation module of the personal gaming device determines the
location of the personal gaming device and sends the location to
the one or more servers, which determine whether the personal
gaming device is located within the designated geographic area. In
various embodiments, the one or more servers enable non-monetary
wager-based game play if the personal gaming device is located
outside of the designated geographic area.
[0229] In various embodiments, the gaming system includes an EGM
configured to communicate with a personal gaming device--such as a
smartphone, a tablet computer, a desktop computer, or a laptop
computer--to enable tethered mobile game play using the personal
gaming device. Generally, in these embodiments, the EGM establishes
communication with the personal gaming device and enables the
player to play games on the EGM remotely via the personal gaming
device. In certain embodiments, the gaming system includes a
geo-fence system that enables tethered game play within a
particular geographic area but not outside of that geographic area.
Examples of tethering an EGM to a personal gaming device and
geo-fencing are described in U.S. Patent Appl. Pub. No.
2013/0267324, entitled "Remote Gaming Method Allowing Temporary
Inactivation Without Terminating Playing Session Due to Game
Inactivity," which is incorporated herein by reference.
Social Network Integration
[0230] In certain embodiments, the gaming system is configured to
communicate with a social network server that hosts or partially
hosts a social networking website via a data network (such as the
Internet) to integrate a player's gaming experience with the
player's social networking account. This enables the gaming system
to send certain information to the social network server that the
social network server can use to create content (such as text, an
image, and/or a video) and post it to the player's wall, newsfeed,
or similar area of the social networking website accessible by the
player's connections (and in certain cases the public) such that
the player's connections can view that information. This also
enables the gaming system to receive certain information from the
social network server, such as the player's likes or dislikes or
the player's list of connections. In certain embodiments, the
gaming system enables the player to link the player's player
account to the player's social networking account(s). This enables
the gaming system to, once it identifies the player and initiates a
gaming session (such as via the player logging in to a website (or
an application) on the player's personal gaming device or via the
player inserting the player's player tracking card into an EGM),
link that gaming session to the player's social networking
account(s). In other embodiments, the gaming system enables the
player to link the player's social networking account(s) to
individual gaming sessions when desired by providing the required
login information.
[0231] For instance, in one embodiment, if a player wins a
particular award (e.g., a progressive award or a jackpot award) or
an award that exceeds a certain threshold (e.g., an award exceeding
$1,000), the gaming system sends information about the award to the
social network server to enable the server to create associated
content (such as a screenshot of the outcome and associated award)
and to post that content to the player's wall (or other suitable
area) of the social networking website for the player's connections
to see (and to entice them to play). In another embodiment, if a
player joins a multiplayer game and there is another seat
available, the gaming system sends that information to the social
network sever to enable the server to create associated content
(such as text indicating a vacancy for that particular game) and to
post that content to the player's wall (or other suitable area) of
the social networking website for the player's connections to see
(and to entice them to fill the vacancy). In another embodiment, if
the player consents, the gaming system sends advertisement
information or offer information to the social network server to
enable the social network server to create associated content (such
as text or an image reflecting an advertisement and/or an offer)
and to post that content to the player's wall (or other suitable
area) of the social networking website for the player's connections
to see. In another embodiment, the gaming system enables the player
to recommend a game to the player's connections by posting a
recommendation to the player's wall (or other suitable area) of the
social networking website.
Differentiating Certain Gaming Systems from General Purpose
Computing Devices
[0232] Certain of the gaming systems described herein, such as EGMs
located in a casino or another gaming establishment, include
certain components and/or are configured to operate in certain
manners that differentiate these systems from general purpose
computing devices, i.e., certain personal gaming devices such as
desktop computers and laptop computers.
[0233] For instance, EGMs are highly regulated to ensure fairness
and, in many cases, EGMs are configured to award monetary awards up
to multiple millions of dollars. To satisfy security and regulatory
requirements in a gaming environment, hardware and/or software
architectures are implemented in EGMs that differ significantly
from those of general purpose computing devices. For purposes of
illustration, a description of EGMs relative to general purpose
computing devices and some examples of these additional (or
different) hardware and/or software architectures found in EGMs are
described below.
[0234] At first glance, one might think that adapting general
purpose computing device technologies to the gaming industry and
EGMs would be a simple proposition because both general purpose
computing devices and EGMs employ processors that control a variety
of devices. However, due to at least: (1) the regulatory
requirements placed on EGMs, (2) the harsh environment in which
EGMs operate, (3) security requirements, and (4) fault tolerance
requirements, adapting general purpose computing device
technologies to EGMs can be quite difficult. Further, techniques
and methods for solving a problem in the general purpose computing
device industry, such as device compatibility and connectivity
issues, might not be adequate in the gaming industry. For instance,
a fault or a weakness tolerated in a general purpose computing
device, such as security holes in software or frequent crashes, is
not tolerated in an EGM because in an EGM these faults can lead to
a direct loss of funds from the EGM, such as stolen cash or loss of
revenue when the EGM is not operating properly or when the random
outcome determination is manipulated.
[0235] Certain differences between general purpose computing
devices and EGMs are described below. A first difference between
EGMs and general purpose computing devices is that EGMs are
state-based systems. A state-based system stores and maintains its
current state in a non-volatile memory such that, in the event of a
power failure or other malfunction, the state-based system can
return to that state when the power is restored or the malfunction
is remedied. For instance, for a state-based EGM, if the EGM
displays an award for a game of chance but the power to the EGM
fails before the EGM provides the award to the player, the EGM
stores the pre-power failure state in a non-volatile memory,
returns to that state upon restoration of power, and provides the
award to the player. This requirement affects the software and
hardware design on EGMs. General purpose computing devices are not
state-based machines, and a majority of data is usually lost when a
malfunction occurs on a general purpose computing device.
[0236] A second difference between EGMs and general purpose
computing devices is that, for regulatory purposes, the software on
the EGM utilized to operate the EGM has been designed to be static
and monolithic to prevent cheating by the operator of the EGM. For
instance, one solution that has been employed in the gaming
industry to prevent cheating and to satisfy regulatory requirements
has been to manufacture an EGM that can use a proprietary processor
running instructions to provide the game of chance from an EPROM or
other form of non-volatile memory. The coding instructions on the
EPROM are static (non-changeable) and must be approved by a gaming
regulators in a particular jurisdiction and installed in the
presence of a person representing the gaming jurisdiction. Any
changes to any part of the software required to generate the game
of chance, such as adding a new device driver used to operate a
device during generation of the game of chance, can require burning
a new EPROM approved by the gaming jurisdiction and reinstalling
the new EPROM on the EGM in the presence of a gaming regulator.
Regardless of whether the EPROM solution is used, to gain approval
in most gaming jurisdictions, an EGM must demonstrate sufficient
safeguards that prevent an operator or a player of an EGM from
manipulating the EGM's hardware and software in a manner that gives
him an unfair, and in some cases illegal, advantage.
[0237] A third difference between EGMs and general purpose
computing devices is authentication--EGMs storing code are
configured to authenticate the code to determine if the code is
unaltered before executing the code. If the code has been altered,
the EGM prevents the code from being executed. The code
authentication requirements in the gaming industry affect both
hardware and software designs on EGMs. Certain EGMs use hash
functions to authenticate code. For instance, one EGM stores game
program code, a hash function, and an authentication hash (which
may be encrypted). Before executing the game program code, the EGM
hashes the game program code using the hash function to obtain a
result hash and compares the result hash to the authentication
hash. If the result hash matches the authentication hash, the EGM
determines that the game program code is valid and executes the
game program code. If the result hash does not match the
authentication hash, the EGM determines that the game program code
has been altered (i.e., may have been tampered with) and prevents
execution of the game program code. Examples of EGM code
authentication are described in U.S. Pat. No. 6,962,530, entitled
"Authentication in a Secure Computerized Gaming System"; U.S. Pat.
No. 7,043,641, entitled "Encryption in a Secure Computerized Gaming
System"; U.S. Pat. No. 7,201,662, entitled "Method and Apparatus
for Software Authentication"; and U.S. Pat. No. 8,627,097, entitled
"System and Method Enabling Parallel Processing of Hash Functions
Using Authentication Checkpoint Hashes," which are incorporated
herein by reference.
[0238] A fourth difference between EGMs and general purpose
computing devices is that EGMs have unique peripheral device
requirements that differ from those of a general purpose computing
device, such as peripheral device security requirements not usually
addressed by general purpose computing devices. For instance,
monetary devices, such as coin dispensers, bill validators, and
ticket printers and computing devices that are used to govern the
input and output of cash or other items having monetary value (such
as tickets) to and from an EGM have security requirements that are
not typically addressed in general purpose computing devices.
Therefore, many general purpose computing device techniques and
methods developed to facilitate device connectivity and device
compatibility do not address the emphasis placed on security in the
gaming industry.
[0239] To address some of the issues described above, a number of
hardware/software components and architectures are utilized in EGMs
that are not typically found in general purpose computing devices.
These hardware/software components and architectures, as described
below in more detail, include but are not limited to watchdog
timers, voltage monitoring systems, state-based software
architecture and supporting hardware, specialized communication
interfaces, security monitoring, and trusted memory.
[0240] Certain EGMs use a watchdog timer to provide a software
failure detection mechanism. In a normally-operating EGM, the
operating software periodically accesses control registers in the
watchdog timer subsystem to "re-trigger" the watchdog. Should the
operating software fail to access the control registers within a
preset timeframe, the watchdog timer will timeout and generate a
system reset. Typical watchdog timer circuits include a loadable
timeout counter register to enable the operating software to set
the timeout interval within a certain range of time. A
differentiating feature of some circuits is that the operating
software cannot completely disable the function of the watchdog
timer. In other words, the watchdog timer always functions from the
time power is applied to the board.
[0241] Certain EGMs use several power supply voltages to operate
portions of the computer circuitry. These can be generated in a
central power supply or locally on the computer board. If any of
these voltages falls out of the tolerance limits of the circuitry
they power, unpredictable operation of the EGM may result. Though
most modern general purpose computing devices include voltage
monitoring circuitry, these types of circuits only report voltage
status to the operating software. Out of tolerance voltages can
cause software malfunction, creating a potential uncontrolled
condition in the general purpose computing device. Certain EGMs
have power supplies with relatively tighter voltage margins than
that required by the operating circuitry. In addition, the voltage
monitoring circuitry implemented in certain EGMs typically has two
thresholds of control. The first threshold generates a software
event that can be detected by the operating software and an error
condition then generated. This threshold is triggered when a power
supply voltage falls out of the tolerance range of the power
supply, but is still within the operating range of the circuitry.
The second threshold is set when a power supply voltage falls out
of the operating tolerance of the circuitry. In this case, the
circuitry generates a reset, halting operation of the EGM.
[0242] As described above, certain EGMs are state-based machines.
Different functions of the game provided by the EGM (e.g., bet,
play, result, points in the graphical presentation, etc.) may be
defined as a state. When the EGM moves a game from one state to
another, the EGM stores critical data regarding the game software
in a custom non-volatile memory subsystem. This ensures that the
player's wager and credits are preserved and to minimize potential
disputes in the event of a malfunction on the EGM. In general, the
EGM does not advance from a first state to a second state until
critical information that enables the first state to be
reconstructed has been stored. This feature enables the EGM to
recover operation to the current state of play in the event of a
malfunction, loss of power, etc. that occurred just before the
malfunction. In at least one embodiment, the EGM is configured to
store such critical information using atomic transactions.
[0243] Generally, an atomic operation in computer science refers to
a set of operations that can be combined so that they appear to the
rest of the system to be a single operation with only two possible
outcomes: success or failure. As related to data storage, an atomic
transaction may be characterized as series of database operations
which either all occur, or all do not occur. A guarantee of
atomicity prevents updates to the database occurring only
partially, which can result in data corruption.
[0244] To ensure the success of atomic transactions relating to
critical information to be stored in the EGM memory before a
failure event (e.g., malfunction, loss of power, etc.), memory that
includes one or more of the following criteria be used: direct
memory access capability; data read/write capability which meets or
exceeds minimum read/write access characteristics (such as at least
5.08 Mbytes/sec (Read) and/or at least 38.0 Mbytes/sec (Write)).
Memory devices that meet or exceed the above criteria may be
referred to as "fault-tolerant" memory devices.
[0245] Typically, battery-backed RAM devices may be configured to
function as fault-tolerant devices according to the above criteria,
whereas flash RAM and/or disk drive memory are typically not
configurable to function as fault-tolerant devices according to the
above criteria. Accordingly, battery-backed RAM devices are
typically used to preserve EGM critical data, although other types
of non-volatile memory devices may be employed. These memory
devices are typically not used in typical general purpose computing
devices.
[0246] Thus, in at least one embodiment, the EGM is configured to
store critical information in fault-tolerant memory (e.g.,
battery-backed RAM devices) using atomic transactions. Further, in
at least one embodiment, the fault-tolerant memory is able to
successfully complete all desired atomic transactions (e.g.,
relating to the storage of EGM critical information) within a time
period of 200 milliseconds or less. In at least one embodiment, the
time period of 200 milliseconds represents a maximum amount of time
for which sufficient power may be available to the various EGM
components after a power outage event has occurred at the EGM.
[0247] As described previously, the EGM may not advance from a
first state to a second state until critical information that
enables the first state to be reconstructed has been atomically
stored. After the state of the EGM is restored during the play of a
game of chance, game play may resume and the game may be completed
in a manner that is no different than if the malfunction had not
occurred. Thus, for example, when a malfunction occurs during a
game of chance, the EGM may be restored to a state in the game of
chance just before when the malfunction occurred. The restored
state may include metering information and graphical information
that was displayed on the EGM in the state before the malfunction.
For example, when the malfunction occurs during the play of a card
game after the cards have been dealt, the EGM may be restored with
the cards that were previously displayed as part of the card game.
As another example, a bonus game may be triggered during the play
of a game of chance in which a player is required to make a number
of selections on a video display screen. When a malfunction has
occurred after the player has made one or more selections, the EGM
may be restored to a state that shows the graphical presentation
just before the malfunction including an indication of selections
that have already been made by the player. In general, the EGM may
be restored to any state in a plurality of states that occur in the
game of chance that occurs while the game of chance is played or to
states that occur between the play of a game of chance.
[0248] Game history information regarding previous games played
such as an amount wagered, the outcome of the game, and the like
may also be stored in a non-volatile memory device. The information
stored in the non-volatile memory may be detailed enough to
reconstruct a portion of the graphical presentation that was
previously presented on the EGM and the state of the EGM (e.g.,
credits) at the time the game of chance was played. The game
history information may be utilized in the event of a dispute. For
example, a player may decide that in a previous game of chance that
they did not receive credit for an award that they believed they
won. The game history information may be used to reconstruct the
state of the EGM before, during, and/or after the disputed game to
demonstrate whether the player was correct or not in the player's
assertion. Examples of a state-based EGM, recovery from
malfunctions, and game history are described in U.S. Pat. No.
6,804,763, entitled "High Performance Battery Backed RAM
Interface"; U.S. Pat. No. 6,863,608, entitled "Frame Capture of
Actual Game Play"; U.S. Pat. No. 7,111,141, entitled "Dynamic
NV-RAM"; and U.S. Pat. No. 7,384,339, entitled, "Frame Capture of
Actual Game Play," which are incorporated herein by reference.
[0249] Another feature of EGMs is that they often include unique
interfaces, including serial interfaces, to connect to specific
subsystems internal and external to the EGM. The serial devices may
have electrical interface requirements that differ from the
"standard" EIA serial interfaces provided by general purpose
computing devices. These interfaces may include, for example, Fiber
Optic Serial, optically coupled serial interfaces, current loop
style serial interfaces, etc. In addition, to conserve serial
interfaces internally in the EGM, serial devices may be connected
in a shared, daisy-chain fashion in which multiple peripheral
devices are connected to a single serial channel.
[0250] The serial interfaces may be used to transmit information
using communication protocols that are unique to the gaming
industry. For example, IGT's Netplex is a proprietary communication
protocol used for serial communication between EGMs. As another
example, SAS is a communication protocol used to transmit
information, such as metering information, from an EGM to a remote
device. Often SAS is used in conjunction with a player tracking
system.
[0251] Certain EGMs may alternatively be treated as peripheral
devices to a casino communication controller and connected in a
shared daisy chain fashion to a single serial interface. In both
cases, the peripheral devices are assigned device addresses. If so,
the serial controller circuitry must implement a method to generate
or detect unique device addresses. General purpose computing device
serial ports are not able to do this.
[0252] Security monitoring circuits detect intrusion into an EGM by
monitoring security switches attached to access doors in the EGM
cabinet. Access violations result in suspension of game play and
can trigger additional security operations to preserve the current
state of game play. These circuits also function when power is off
by use of a battery backup. In power-off operation, these circuits
continue to monitor the access doors of the EGM. When power is
restored, the EGM can determine whether any security violations
occurred while power was off, e.g., via software for reading status
registers. This can trigger event log entries and further data
authentication operations by the EGM software.
[0253] Trusted memory devices and/or trusted memory sources are
included in an EGM to ensure the authenticity of the software that
may be stored on less secure memory subsystems, such as mass
storage devices. Trusted memory devices and controlling circuitry
are typically designed to not enable modification of the code and
data stored in the memory device while the memory device is
installed in the EGM. The code and data stored in these devices may
include authentication algorithms, random number generators,
authentication keys, operating system kernels, etc. The purpose of
these trusted memory devices is to provide gaming regulatory
authorities a root trusted authority within the computing
environment of the EGM that can be tracked and verified as
original. This may be accomplished via removal of the trusted
memory device from the EGM computer and verification of the secure
memory device contents is a separate third party verification
device. Once the trusted memory device is verified as authentic,
and based on the approval of the verification algorithms included
in the trusted device, the EGM is enabled to verify the
authenticity of additional code and data that may be located in the
gaming computer assembly, such as code and data stored on hard disk
drives. Examples of trusted memory devices are described in U.S.
Pat. No. 6,685,567, entitled "Process Verification," which is
incorporated herein by reference.
[0254] In at least one embodiment, at least a portion of the
trusted memory devices/sources may correspond to memory that cannot
easily be altered (e.g., "unalterable memory") such as EPROMS,
PROMS, Bios, Extended Bios, and/or other memory sources that are
able to be configured, verified, and/or authenticated (e.g., for
authenticity) in a secure and controlled manner.
[0255] According to one embodiment, when a trusted information
source is in communication with a remote device via a network, the
remote device may employ a verification scheme to verify the
identity of the trusted information source. For example, the
trusted information source and the remote device may exchange
information using public and private encryption keys to verify each
other's identities. In another embodiment, the remote device and
the trusted information source may engage in methods using zero
knowledge proofs to authenticate each of their respective
identities.
[0256] EGMs storing trusted information may utilize apparatuses or
methods to detect and prevent tampering. For instance, trusted
information stored in a trusted memory device may be encrypted to
prevent its misuse. In addition, the trusted memory device may be
secured behind a locked door. Further, one or more sensors may be
coupled to the memory device to detect tampering with the memory
device and provide some record of the tampering. In yet another
example, the memory device storing trusted information might be
designed to detect tampering attempts and clear or erase itself
when an attempt at tampering has been detected. Examples of trusted
memory devices/sources are described in U.S. Pat. No. 7,515,718,
entitled "Secured Virtual Network in a Gaming Environment," which
is incorporated herein by reference.
[0257] Mass storage devices used in a general purpose computing
devices typically enable code and data to be read from and written
to the mass storage device. In a gaming environment, modification
of the gaming code stored on a mass storage device is strictly
controlled and would only be enabled under specific maintenance
type events with electronic and physical enablers required. Though
this level of security could be provided by software, EGMs that
include mass storage devices include hardware level mass storage
data protection circuitry that operates at the circuit level to
monitor attempts to modify data on the mass storage device and will
generate both software and hardware error triggers should a data
modification be attempted without the proper electronic and
physical enablers being present. Examples of using a mass storage
device are described in U.S. Pat. No. 6,149,522, entitled "Method
of Authenticating Game Data Sets in an Electronic Casino Gaming
System," which is incorporated herein by reference.
[0258] Various changes and modifications to the present embodiments
described herein will be apparent to those skilled in the art. Such
changes and modifications can be made without departing from the
spirit and scope of the present subject matter and without
diminishing its intended advantages. It is therefore intended that
such changes and modifications be covered by the appended
claims.
