Method and apparatus for enhanced play of a gaming device
Abstract
An electronic amusement device and a method for operating the
device are disclosed. In accordance with one embodiment, a slot
machine identifies a tracked symbol and initializes a running count
representing active occurrences of the tracked symbol generated
during a play session. During the session, the slot machine
generates at least one outcome represented by a set of symbols and
determines whether the outcome includes an occurrence of a tracked
symbol. The slot machine adjusts the running count, increasing the
running count to reflect occurrences of the tracked symbol and, in
some embodiments, decreasing the running count to reflect
expiration of occurrences of the tracked symbol. Once the running
count reaches a predetermined level, the slot machine determines a
bonus payout based on the running count.

BACKGROUND
[0009] The present invention relates generally to gaming
devices.
[0010] Modern casinos offer players a wide variety of game
alternatives, including table games such as craps, blackjack and
poker. Slot machines, however, constitute the major source of
profits for casinos. Casinos therefore constantly strive to
increase the attractiveness and playability of slot machines in
ways that attract and retain players.
[0011] More particularly, it is of substantial value to a casino to
encourage lengthier and faster play sessions at slot machines. When
a player terminates play and walks away from a slot machine, that
machine often goes unused for some period of time until a new
player initiates play, thereby reducing revenue from that slot
machine. Further, the speed with which an active player operates a
machine has a direct bearing on the profit of a machine; the faster
a slot machine is played, the greater the profit that machine will
generate for its owner.

DETAILED DESCRIPTION
[0023] Various embodiments of the present invention provide an
improved method and apparatus for determining a bonus payout based
on a running count of tracked symbol occurrences. For a casino
operator, an advantage of various embodiments is to sustain the
attention of slot machine players for a longer time, thereby
increasing the average playing time for a slot machine. Another
advantage, for a casino operator, of various embodiments is to
encourage faster slot machine play by players using the device. An
advantage, for a slot machine player, of various embodiments is to
increases the excitement, anticipation and enjoyment of playing a
slot machine.
[0024] According to an embodiment of the invention, an electronic
amusement device and method is disclosed for directing a slot
machine to process a bonus payout based on a running count of
tracked symbol occurrences. The method includes the steps of
identifying at least one tracked symbol and initializing a running
count. The running count represents a number of occurrences of the
tracked symbol, for example, during a particular time period or
throughout a number plays of the slot machine.
[0025] The method may also include the steps of generating an
outcome represented by a set of symbols, and determining an
occurrence of any of the identified tracked symbols. The running
count is adjusted accordingly, including increasing the running
count to reflect occurrences of one of the tracked symbols and, in
some embodiments, decreasing the running count to reflect
expiration of occurrences of one of the tracked symbols. A bonus
payout is determined based on the running count.
[0026] Slot machines, including conventional reel slot machines,
video poker, video keno and video blackjack machines, are generally
among the most profitable casino games. Casino operators can
capture the interest of slot players by offering a bonus payout in
addition to a traditional payout. By determining the bonus payout
based on aggregated results of multiple plays during a gaming
session, casino operators can encourage slot players to increase
the average duration of their sessions. Further, because the bonus
payout is based on multiple plays, such a bonus increases the
anticipation, entertainment and excitement of a slot player.
[0027] In embodiments of the invention, a device (e.g. a slot
machine, a server) determines whether a number of occurrences of a
tracked symbol during a session of game play is sufficient to
provide a bonus payout. The device maintains a running count of
tracked symbols that have occurred and that are unexpired, during a
gaming session. A bonus payout is determined based thereon (e.g.
when the running count reaches or surpasses a predetermined
amount).
[0028] In embodiments of the invention, a player begins a gaming
session at a slot machine. During the session, the player plays a
number of games, and generates an outcome for each game. Each
outcome is represented by a set of symbols.
[0029] The slot machine identifies at least one tracked symbol, and
throughout the session, the slot machine maintains a running count
of the number of times the tracked symbol occurs in a generated
outcome. In one embodiment, the running count may represent the
number of times a specific symbol occurs in generated outcomes. In
an alternate embodiment, the running count may represent the number
of times any tracked symbol occurs in generated outcomes.
[0030] In some embodiments, although each occurrence of a tracked
symbol causes the running count to be increased, an expiration
condition is associated with each occurrence of a tracked symbol
defining the condition under which the occurrence expires.
Typically, an expiration condition is defined as a function of time
or as a function of a number of plays. However, an expiration
condition may alternatively be a function of a stored rule, and/or
an event internal or external to game play, as discussed more fully
herein. Upon the satisfaction of an expiration condition, the
running count is decreased to reflect the expiration of an
occurrence.
[0031] Embodiment will be further described with reference to a
client-server architecture in which much of the processing is
performed by the networked gaming device (client). Of course, one
of ordinary skill in the art will readily recognize various
alternate embodiments that are consistent with the spirit and scope
of the present invention, including without limitation performing
the processing steps at a slot server.
[0032] Apparatus Architecture
[0033] FIGS. 1-3 generally illustrate the architecture of an
apparatus according to an exemplary embodiment of the invention.
FIG. 1 depicts a block diagram of a slot network 100. The network
100 includes a slot machine server 200 ("server") that is linked to
and communicates with networked gaming devices or slot machines
300, 302 and 304. Although three gaming devices are shown, any
number of networked gaming devices could be linked to and/or in
communication with the server 200.
[0034] FIG. 2 illustrates the architecture of the server 200.
Server 200 includes a processor 202, a storage device 204 and a
communication port 220, as well as conventional server components
well known in the art. A communication port 220 enables the server
200 to communicate with gaming devices 300, 302 and 304. Storage
device 204 comprises an appropriate combination of magnetic and
optical memory, such as disk drive memory, and semiconductor memory
such as random access memory and read only memory. Storage device
204 contains program 206 and player table 208 for controlling
server 200 in accordance with various embodiments of the present
invention.
[0035] Various computer readable media may also store programs such
as program 206. For example, a program may be stored in media such
as compact discs, DVDs, and in electromagnetic transmissions (e.g.
computer network transmissions).
[0036] FIG. 3A illustrates the architecture of slot machine 300.
Slot machine 300, which may be substantially similar to slot
machines 302 and 304, is controlled by processor 302 and
communicates with slot server 200 via communication port 348.
Processor 302 is connected to storage device 304, which stores
program instructions and data for operating slot machine 300 in
accordance with embodiments of the present invention. Storage
device 304 can store tracked symbol table 400, occurrence table
450, payout table 500, probability table 600, outcome table 700 and
tracked symbol reward table 800, described more fully with
reference to FIGS. 4A-8, respectively. Storage device 304 further
stores program 306 which preferably includes instructions for
directing the processor 302, such as directing the processor to
conduct a game of chance and instructions for implementing a method
of determining the bonus payout. In addition, a gaming device (e.g.
slot machine) may receive one or more programs (e.g. program 306)
from a server (e.g. server 200), and run that program.
[0037] Further connected to processor 302 are a clock 308, a player
card tracking device 338, a random number generator 322, a reel
controller 324 for controlling reels 326, 328 and 330, a hopper
controller 332 having an associated hopper 334, a currency acceptor
320, a video display 336 and a tracked symbol meter 360. It should
be noted that video display 336 may display information which may
serve as an adequate substitute for tracked symbol meter 360 as
well as for reels 326, 328 and 330.
[0038] As illustrated, slot machine 300 comprises many conventional
components. Some non-conventional components of slot machine 300
include the program instructions and data stored in storage device
304, as well as the tracked symbol meter 360. For purposes of
better illustrating the embodiments, several conventional
components, well known to those skilled in the art, are described
only briefly. Although the present embodiment of the invention is
described as implemented with physical components, the invention
applies equally well to and includes software embodiments such as
would be implemented on the Internet and other computer data
networks.
[0039] Processor 302 may be embodied as one or more well known
processing units, for example a Pentium class CPU manufactured by
Intel Corp., or the like. Data storage device 304 comprises an
appropriate combination of magnetic and optical memory, such as
disk drive memory, and semiconductor memory such as random access
memory and read only memory. In addition to the program
instructions and data shown in FIG. 3, storage device 304 stores
appropriate operating system and control software (not shown),
functional to operate gaming device 300 in the manner described
below. Random number generator 322 comprises one of many well known
random or pseudo-random number generators suitable for use in a
gaming device.
[0040] Currency acceptor 320 is operative to receive one or more
coins or bills, and to transmit an appropriate value signal to
processor 302. Hopper controller 332, and hopper 334 connected
thereto, are operative under the control of processor 302 to
dispense coins to a player. Starting controller 350 comprises a
player-operated device such as a handle or button for initiating
the play of a game.
[0041] Player card tracking device 338 comprises a player tracking
interface including a card reader/writer 346 for receiving a player
tracking card (not shown), a display 344 for communicating messages
to the player, and a keypad 342 for receiving player input such as
a player identifier.
[0042] 3B depicts a front plan view of slot machine 300. For
purposes of discussion, the slot machine 300 is generally
illustrated as divided into three sections: a central panel 370, a
lower panel 380, and an upper panel 390. Central panel 370 includes
the display of first reel 326, second reel 328, and third reel 330.
Each of these reels is configured to display the symbols printed on
an associated reel strip. The reels may be mechanical in nature, or
electronically represented with outputs shown on conventional
electronic displays, such as a liquid crystal display ("LCD").
Central panel 370 includes a payline 372 that indicates the symbols
of a resultant outcome. Central panel 370 further includes starting
controller 350, in the form of a handle.
[0043] Lower panel 380 houses player tracking device 338. To the
right of player tracking device 338 is tracked symbol meter 360
which indicates the number of tracked symbols which have been
accumulated by the player. On the right portion of lower panel 380
is currency acceptor 320 and starting controller 350.
[0044] Upper panel 390 includes a display showing the contents of
payout table 500 which describes all possible payouts for the slot
machine, the details of which are discussed with respect to FIG. 5.
The information is typically printed in bright colors and may be
back-lit for easier viewing. Upper panel 390 also includes a
display showing the requirements and payouts of the bonus game.
[0045] Data Tables
[0046] The tables illustrated below convey information regarding
data which may be stored and/or processed in various embodiments of
the invention. Those of ordinary skill in the art will readily
understand that many other representations of the illustrated
tables are possible, including more or less tables, and tables
which allow for different data and different functionality. In
addition, descriptions of when and how data is calculated or stored
in tables would be readily understood as merely examples of several
possible alternatives. In fact, different structures besides tables
and the like may be employed, as would be well understood by those
of ordinary skill in the art.
[0047] Referring now to FIG. 4A, there are illustrated three
representative records of an exemplary tracked symbol table 400. As
illustrated, each record of tracked symbol table 400 represents the
progress of a player toward achieving a bonus associated with a
tracked symbol. Each record of tracked symbol table 400 includes a
symbol 410 and a count 412. Symbol field 410 identifies the tracked
symbol associated with the record, and running count field 412
identifies the number of non-expired occurrences of the symbol
generated during a session. Accordingly records 420, 430 and 440 of
tracked symbol table 400 show that during the current session of
play, a player has an active total of 12 bell symbols, 29 orange
symbols and 2 bar symbols, respectively. The displayed running
count for each tracked symbol is periodically adjusted to account
for expired occurrences of tracked symbols.
[0048] Referring now to FIG. 4B, there are illustrated ten
representative records of an exemplary occurrence table 450. Each
record of occurrence table 450 represents a single occurrence of a
tracked symbol generated during a session. Each record of
occurrence table 450 includes occurrence identifier field 452 which
uniquely identifies a record. Symbol field 454 identifies the
tracked symbol associated with the record.
[0049] The time and date that the symbol was generated is stored in
occurrence time/date field 456, and time at which the occurrence
expires is stored in expiration time/date field 458. Although the
expiration time/date is illustrated as an expiration condition,
other expiration conditions are also possible, such as number of
plays. As illustrated by the records of occurrence table 450,
ORANGE symbols expire twenty minutes after occurring, BAR symbols
expire twenty-five minutes after occurring and BELL symbols expire
thirty minutes after occurring. Expiration conditions may be
recorded in tabular format as illustrated by Table I, below, and
stored in storage device 204 and/or storage device 304.
1TABLE I Expiration Condition Table Expiration Period Symbol
(minutes) Orange 20 Bar 25 Bell 30
[0050] Although the exemplary records reflect expiration periods
that are based on the associated tracked symbol, in an alternate
embodiment of the present invention, random expiration periods
could be assigned for every occurrence.
[0051] Status field 460 represents the status of the occurrence
represented by a record. Status field 460 can store an indication
of "ACTIVE" or "EXPIRED." If status field 460 contains "ACTIVE,"
the occurrence is included in the running count for the associated
symbol. If status field 460 contains "EXPIRED," the occurrence of
the symbol is not included in the running count. Assuming that
clock 308 generates the current date/time of Sep. 28, 1998 12:25
pm, as illustrated by reference numeral 490, records 470 and 472
illustrate the use of status field 460. As shown, the occurrence
represented by record 470 expired at 12:24 pm, one minute prior to
the current date/time. Accordingly, status field 460 of record 470
is set to "EXPIRED." Similarly, the occurrence represented by
record 472 will expire at 12:29 pm, four minutes from the current
date/time. Thus, status field 460 of record 472 is set to
"ACTIVE."
[0052] Referring now to FIG. 5, there is depicted an exemplary
conventional payout table 500. Each record of payout table 500
defines the payout awarded for each outcome, or family of outcomes,
based on the number of coins wagered. Payout table 500 includes
outcome field 502 representing the outcome or family of outcomes
associated with a record. Payout table 500 also includes payout
fields 504, 506 and 508 representing the payouts for wagers of one,
two and three coins, respectively. For example, if a player wagers
one coin on a play that results in an outcome of
"BAR/ORANGE/ORANGE," slot machine 300 would provide a payout of ten
coins, according to payout field 504 of record 522. If two coins
were wagered on a play having the same outcome, slot machine 300
would provide a payout of twenty coins, according to payout field
506 of record 522.
[0053] FIG. 6 depicts a table representing the probability of
specific outcomes generated by slot machine 300. Although no
specific probability table is required, the selection of a
probability table should be consistent with the requirements and
payout amounts of the bonus game. Each record of probability table
600 represents an outcome or family of outcomes. Probability table
600 includes an outcome field 602 representing an outcome
associated with a record. Probability table 600 further includes
random number field 604 and expected hits per cycle field 606.
Random number field 604 indicates a range of numbers which, when
generated by random number generator 322, result in the associated
outcome. For example, random numbers 10131-10330 correspond to
outcomes for which the last two symbols are "CHERRY," as
illustrated by record 616. Outcomes of "ANY/CHERRY/CHERRY" are
expected to occur 200 times per cycle of 10,648 total plays in the
cycle.
[0054] Referring now to FIG. 7, there is depicted outcome table 700
of slot machine 300. Each record of outcome table 300 represents an
outcome generated by a play of slot machine 300. Although outcome
table 700 may store every outcome from every session, in the
illustrated embodiment, outcome table 700 stores the outcomes from
every play of a current session. Outcome table 700 includes outcome
identifier 702 that functions as a record identifier. Outcome table
700 also includes fields 704, 706 and 708 that represent the
symbols from reel 1, reel 2 and reel 3, respectively, which
together form the outcome.
[0055] Referring now to FIG. 8, there is depicted tracked symbol
reward table 800 of slot machine 300. Each record of table 800
represents a bonus payout and the requirements for achieving the
bonus payout. Table 800 includes symbol field 810 and count
required field 812. Symbol field 810 and count required field 812
define the requirements for achieving a bonus payout associated
with a record. Bonus payout field 814 defines the amount of the
bonus payout awarded to a player who achieves the associated
requirements.
[0056] Operation
[0057] The operation of various embodiments of the apparatus will
now be described in greater detail with reference to FIGS. 9A and
9B. Taken together, FIGS. 9A and 9B depict a flowchart of an
exemplary process 900 employed by slot machine 300 to determine a
bonus payout. The process steps may be implemented using the
instructions of program 306.
[0058] The process begins with step 902 in which processor 302
receives a signal to initiate a session. Such a signal could be
generated as a result of a player inserting a player tracking card.
The session initiation signal could also be generated based on
insertion of currency after an extended period during which the
slot machine was not used. The session initiation signal represents
the beginning of a new session.
[0059] The process continues with step 910 which directs processor
302 to receives a signal to initiate game play, such as by a pull
of handle 350. At step 912, processor 302 determines an outcome for
the game and provides the player a payout associated with the
outcome, as shown by step 914. Steps 910-914 are game play steps
which may be performed in conjunction with certain operating system
and control software (not shown) to conduct the primary game
offered by slot machine 300.
[0060] Steps 916 through 922 define a loop that causes each reel of
the slot machine to be examined to determine whether the outcome
includes any tracked symbols. At step 916, processor 302 determines
which symbol is on the next reel that has not been examined. The
first time through the loop, the first reel 326 is considered the
next reel that has not been examined. Step 918 directs the flow of
processing based on whether the determined symbol is a symbol which
is tracked for the purpose of awarding a bonus payout. If the
determined symbol is a tracked symbol, processor 302 is directed to
update the running count of the tracked symbol. Otherwise,
processor 302 determines whether all of the reels have been
examined, and causes the process flow to loop back to step 916,
accordingly.
[0061] Referring now to FIG. 9B, steps 924 through 936 define a
logical loop that causes processor 302 to examine the running count
of each tracked symbol to determine whether a reward level has been
achieved. At step 924, the running count 412 of a tracked symbol is
retrieved from tracked symbol table 400 and compared to the
corresponding count required 812 of tracked symbol reward table. As
illustrated by step 926, if a reward level has not been achieved,
processor 302 is directed to proceed to step 936.
[0062] If a reward level has been achieved, processor 302
determines the reward at step 928 and provides the reward to the
player at step 930. The reward is determined by retrieving the
corresponding bonus payout 814 from tracked symbol reward table
800. The reward may be provided to the player in a number of ways,
including dispensing coins, updating a credit meter, or crediting
an account of the player based on identifying information stored on
a player tracking card.
[0063] At step 932, processor 302 adjusts the running count of the
tracked symbol to reflect the reward. In its simplest form, step
932 includes subtracting the count required to achieve the reward
from the corresponding running count. Alternately, step 932 could
include setting the running count to zero, or in an embodiment in
which each occurrence is individually tracked, step 932 would
include updating the table of occurrences 450. At step 934,
processor 302 is directed to adjust the running count of the
tracked symbol to reflect expired occurrences. At step 936,
processor 302 is directed to continue examining tracked symbols
until all tracked symbols have been examined.
[0064] At step 938, processor 302 determines whether the session
has been terminated. If the session has not been terminated,
process flow is directed back to step 910. Otherwise, the process
concludes. The determination of whether a session has been
terminated may be made in any number of ways, including detecting
the removal of a player tracking card from player tracking device
338. Alternatively, slot machine 300 may determine that a session
has been terminated after an extended period of inactivity.
[0065] Value of Tracked Symbols
[0066] Many embodiments of the present invention are possible. One
series of embodiments addresses the valuation of tracked symbols
for purposes of affecting a player's ability to qualify for a bonus
payout. In embodiments where winning the bonus requires
accumulation of a sum of values, different tracked symbols can be
assigned different values. For example, the bonus payout may
require accumulation of 50 points, where cherries are worth 1 point
each, oranges are worth 2 points each, bells are worth 10 points
each, and bars are worth 15 points each.
[0067] Alternatively, the bonus game may be presented on an
accompanying visual display as an automobile or horse racing game,
where different reel symbols affect a player's standing in the
race. Reel symbols and the values they represent may dictate the
distance traveled or speed attained by a player's car or horse
(e.g. a bell symbol advances the player's car one tenth of the
track length, while a bar symbol advances the player's car one
seventh of the track length). Conversely, the reel symbols and the
values they represent may negatively affect the player's standing
in the race, for example by indicating gas consumption, a flat tire
or a pit stop. Negative symbols could temporarily or permanently
reduce or eliminate the player's ability to compete against (1)
"virtual" cars or horses (operated automatically by server 200 or
the gaming device) or (2) the cars or horses associated with
players at other gaming devices. For example, the game may dictate
that should a player receive a "7" symbol, a flat tire results,
forcing the player's car to cease racing until either 15 seconds
pass or until 2 more spins are initiated. This example illustrates
that relatively greater payouts normally accompanying infrequent
outcomes (e.g. "7's") can be offset by imposing a negative effect
on the player's standing toward the bonus payout. Further, where
the player's ability to re-enter the race is dependent on an
increased rate of play, the casino benefits as players will likely
spend more money at quicker rates.
[0068] Alternatively, where the game requires accumulation of a
certain amount of points but only allows for accumulation of a
single symbol-type (e.g. cherries), the symbol may be awarded
differing point values depending on (1) point of time in the game
session (e.g. lower points may be awarded later in the session),
(2) the outcomes and payouts generated in the underlying game (e.g.
lower points may be awarded if the player has received a certain
number of winning outcomes during the game session), (3) the reel
position in which the symbol was generated (e.g. if a cherry symbol
is in the third reel, 10 extra points are awarded), (4) the
occurrence of supplementary symbols in a given outcome (e.g.
cherries accompanied by bars are awarded 10 extra points).
[0069] In yet another alternate embodiment, the value of
accumulated tracked symbols may vary over time according to
predetermined rules. Thus, in a game requiring accumulation of an
apple symbol, an orange symbol, and a pear symbol, the value of the
first two symbols accumulated may vary until a completing symbol is
obtained, at which point a sum value can be determined and a payout
awarded accordingly. For example, apple symbols may have values
that at first increase by one value point every 5 seconds for the
first 30 seconds after they are initially accumulated, and then
decrease thereafter at a rate of one value point every 5 seconds
until the value reaches zero, or until the game ends (whichever
comes first). Orange symbols may have values that at first increase
by five value points every 10 seconds for the first 60 seconds
after they are initially accumulated, and then decrease thereafter
at a rate of ten value points every 20 seconds until the value
reaches zero, or until the game ends (whichever comes first). Pear
symbols may have values that at first increase by ten value points
every 5 seconds for the first 20 seconds after they are initially
accumulated, and then decrease thereafter at a rate of five value
points every 10 seconds until the value reaches zero, or until the
game ends (whichever comes first). In this manner, every fruit
symbol in the game "ripens" and "perishes" at different rates.
Depending on the when the player completes the game by accumulating
all of the required tracked symbols (in the above example, one
apple, one orange, and one pear), the total value of the player's
points are effected. Accordingly, players accumulating the symbols
at different times during a game session will receive differing
total point values, and may be awarded different bonuses.
[0070] Expiration of Tracked Symbols
[0071] According to various embodiments, each occurrence of a
tracked symbol has an associated expiration criterion. As
described, each accumulated tracked symbols expire after a
predetermined time. An advantage of a time-based embodiment is that
it encourages players to play quickly. Although fast players will
tend to win more bonuses, they will also tend to spend more money
playing the slot machine. Alternatively, accumulated tracked
symbols may expire after a pre-determined number of plays. For
example, after 100 plays, a bell symbol expires. In either event,
the accumulation of tracked symbols allows players to feel that
increased game play will result in a reward if such accumulation
meets a predetermined level, while the expiration of tracked
symbols serves to make attainment of the predetermined level more
difficult, thereby allowing for larger payouts, increasing
excitement, and encouraging additional game play. The accumulation
and expiration of tracked symbols may be represented to the player
visually, for example, by (1) images representative of the tracked
symbols which visually "decay" or "perish" in accordance with
expiration status, (2) images representative of tracked symbols
which visually accumulate as part of a pyramid (or other structure)
and gradually disappear or are removed to reflect expiration, or
(3) images representative of the tracked symbols and corresponding
images of clocks or other timers indicating the images' individual
expiration statuses.
[0072] In an alternate embodiment, accumulated tracked symbols may
have individual expiration rules so that such symbols expire at
different rates. In another alternate embodiment, the expiration
periods of each accumulated tracked symbol may be effected
positively (i.e., prolonged) or negatively (i.e., shortened), in
varying degrees, by certain events. For example, the outcomes and
payouts associated with the underlying slot game may prolong or
shorten expirations associated with accumulated symbols. Thus, the
occurrence of any payout over $100 may cause an accelerated rate of
expiration for any or all of the collected symbols. Or, the
simultaneous occurrence of two "bar" symbols in any position on the
pay line may prolong the expiration periods of certain accumulated
symbols (e.g. by adding 10 minutes to the expiration dates of the
first 5 symbols acquired in the gaming session).
[0073] Further, "opponents" that a player may face in a game may
effect expiration periods positively or negatively. That is, the
expiration periods of certain accumulated symbols may be prolonged
or shortened based on the activities of other, competing players.
In an embodiment where slot machines are connected via network, the
outcomes of other games may effect the expiration periods
associated with a player's session. For example, players in a
neighboring bank of slot machines may compete for a single bonus
prize, such as an automobile. Players may receive outcomes that
shorten the expiration periods associated with symbols accumulated
by other players, thereby increasing the player's standing in the
game relative to the competing players. Similarly, a player's game
may be effected by a "virtual" opponent, such as a game character
controlled by server 200.
[0074] Alternatively, the expiration periods of certain symbols may
be effected positively or negatively based on the occurrence or
nonoccurrence of events external to the game. In such an
embodiment, a real-time data link can be established between
communication port 220 of server 200 and a remote server configured
to provide data about the relevant external event. Example external
event data that may effect the expiration periods of accumulated
tracked symbols include (1) weather data, (2) financial (e.g.
securities) data, and (3) data reflecting outcomes or payouts of
other games. It should be noted that, in a similar manner, external
event data may also effect the value of certain symbols, such as a
point value.
[0075] In an alternative "front-loading" embodiment, there may be a
relatively faster accumulation of symbols in the earlier portion of
a game session and relatively slower accumulation of symbols in the
later portion of the game session. In this embodiment, the
aforementioned expiration function may or may not be desirable, as
expiration in conjunction with front loading would significantly
decrease the likelihood of the player winning a bonus.
Front-loading configurations function to give players the
impression that large jackpots are readily attainable, when in fact
it becomes increasingly more difficult to attain. In other words,
such a front-loading configuration would increase the anticipation
and excitement of the game because the player would believe that he
is on the verge of a bonus payout. In practice, casinos may wish to
disclose the use of front-loading to players prior to the
initiation of a game session so that they are not disappointed
after game session has begun.
[0076] Accelerated accumulation earlier in the game can be achieved
by configuring the game such that certain required symbols are more
likely to occur than other required symbols. For example, in a game
that requires the player to collect twenty oranges, twenty cherries
and twenty bells, the player may sense more progress earlier in the
game as the collection of more common symbols (cherries and
oranges) occurs more frequently. However, as the game goes on, the
player would realize that accumulation of the less common symbols
(bells) requires a relatively prolonged session.
[0077] Alternatively, in a front-loading embodiment where there is
one symbol that must be accumulated (e.g. the player must collect
50 oranges), the machine may be configured to provide those
outcomes less frequently after a certain amount of time (e.g. after
the first hour of play), or after a certain number of occurrences
(e.g. after 25 oranges have been collected). Or, the odds of the
symbol's occurrence in a game outcome may remain unchanged, but the
rate at which the symbol is credited toward the bonus payout may
decrease. For example, in such a game that requires accumulation of
a single symbol type (e.g. an orange), the accumulation of the
symbols can be visually communicated to the player via a digital
representation of a pyramid that is assembled throughout the game
session. If the player is required to collect 50 oranges in order
to qualify for a bonus, collected oranges may fill the bottom
portion of the pyramid earlier in the game session. Later in the
game session, when outcomes resulting in oranges are less likely to
lead to accumulation of oranges for bonus payout purposes, oranges
that result from game play are less likely to stay on top of the
pyramid. In other words, as the pyramid gets higher, game outcomes
may result in oranges, but such oranges may "roll off" the sides of
the pyramid and not be credited toward the achievement of a bonus
payout. In this manner, the probability table of the underlying
slot game need not be changed to accommodate front-loading in the
bonus game.
[0078] Storage of Running Counts
[0079] Although embodiments were described in which running counts
were stored locally at the slot machine, the running counts could
be, e.g. associated with a player identifier from a player tracking
card and stored by server 200. This would allow a player to "carry"
the running counts from slot machine to slot machine. Occurrences
of tracked symbols stored with the server might expire, e.g. after
a number of hours or days. Such an embodiment also enables a player
to end a playing session, save the running counts, and return to
the same machine at a later time to resume the game using the
stored running counts.
[0080] Alternatively, the running counts of accumulated tracked
symbols could be stored on the player's tracking card. Such an
embodiment would also allow a player to carry running counts from
slot machine to slot machine. Any existing running counts would be
stored on a player's tracking card at the end of a playing session.
The running counts would be read off the card by the next slot
machine into which the tracking card is inserted. That machine's
running counts would be adjusted accordingly. This embodiment
requires that the player card have data storage capability, such as
that found in a smart card or writable magnetic strip.
[0081] Alternate Rewards
[0082] In addition to variations in the expiration of accumulated
tracked symbols, variations in determining a bonus payout are also
possible. Specifically, the determination of a bonus payout could
be based on how many spins or how much time it took to achieve the
reward level. For example, the bonus payout for accumulating 100
oranges may be 350 coins if they are accumulated within 30 spins,
325 coins if they are accumulated within 40 spins, and 300 coins if
they are accumulated within 50 spins.
[0083] Alternatively, the reward provided to a player for attaining
a particular reward level might be a payout multiplier instead of
coins. For example, upon reaching 50 oranges, the player might earn
a ten times multiplier for "ORANGE/ORANGE/ORANGE" enabled for the
next 100 handle pulls. In yet another embodiment, slot club reward
points could be awarded in place of currency.
[0084] Rewards could also be provided for expiring occurrences of
tracked symbols. For example, every time a tracked symbol expires
(i.e. is deducted from the running count), the player would be
awarded a slot club reward point, a percentage of a slot club
reward point or a cash-back reward (e.g. $0.01). The reward point
or cash-back could then be used in the casino restaurants and/or
shops. This extra reward would make the gaming experience more
enjoyable by rewarding the player for events that would otherwise
be considered "non-winning" events during slot play. The reward
point or cash-back earned by the player would be tracked through
the player's tracking card in a conventional manner.
[0085] As another alternative reward, players may be provided with
the option of foregoing a bonus in exchange for credit in a new
gaming session. For example, a player who has accumulated all
necessary symbols and accordingly qualifies for a bonus from an
initial game session may be offered the ability to apply half of
their accumulated symbols to a new game session offering a larger,
more valuable bonus if they agree to forego the bonus due from the
initial game session. In another embodiment, players are simply
awarded the initial bonus, and issued a credit toward the
accumulation of bonus symbols in the next game session. Such an
embodiment would encourage players to keep playing a game after the
attainment of the initial bonus.
[0086] Group/Team Play
[0087] Although the described embodiment is directed toward
individual play, it should be understood that an alternate
embodiment of the present invention could support group play.
Players could form teams, pooling their accumulated tracked symbols
into running counts corresponding to the team. Once the once a
reward level is achieved by the team, each team member would be
provided a share of the associated bonus. A team may be formed
interactively by allowing the player to actuate a "Team Play"
button on the gaming device (not shown). Server 200 would link the
player to at least one other player in response to the signal
resulting from the actuated "Team Play" button.
[0088] Alternatively, players may form teams by registering at a
kiosk or casino slot club center. In such an embodiment, the player
identifiers of the team members would be stored in association with
one another and a team identifier in a registration table. The
registration table would be accessed when a team member inserts his
tracking card into the card reader of a slot machine. The slot
would read the player identifier from the player tracking card and
transmit it to the server. The server would determine whether the
player is registered on a team and, if so, would retrieve the team
record in order to update any symbols accumulated by the player
into the running counts of the team.
[0089] Rules Variations
[0090] A slot machine could also include program steps for
alternate rules. Specifically, each tracked reel symbols could be
associated with a particular reel. For example, on a three reel
machine, only bars occurring on the first reel would be
accumulated, only bells appearing on the second reel would be
accumulated and only oranges appearing on the third reel would be
accumulated. A tracked symbol meter could be disposed above each
reel for visual association.
[0091] Other variations of the disclosed embodiment are also
envisioned. Specifically, an alternative embodiment of the present
invention could require that a tracked symbol only counts towards
the running count if it is not part of a winning combination. Since
players may be rewarded in various ways even when their outcome is
not a winning one, it is not strictly necessary to reward players a
second time for a winning outcome. For example, if bars, bells, and
oranges are tracked symbols, and the player receives an outcome of
CHERRY-CHERRY-ORANGE, he receives a payout of five coins for every
coin wagered in accordance with a conventional payout schedule.
Employing the alternate embodiment of the present invention, the
player would receive the payout of five coins (if he only wagered
one coin) and the orange that is part of that outcome would not be
added to the running count of oranges.
[0092] Other variations in the rules are also possible. For
example, the rules could be altered to adjust the running count
only if the player has wagered the maximum amount allowable.
Another variation of the rules may enable a player to receive
credit for an occurrence of a tracked symbol, even if it is not
part of an outcome. Specifically, symbols that are not on the
payline but appear on the screen of the slot machine count towards
the running count. For example, if an orange is just above or below
the payline and oranges are tracked symbols, the running count for
oranges would be adjusted.
[0093] Another variation of the rules includes cancellation of
symbols. In this embodiment, one type of reel symbol may cancel
another. In other words, one type of reel symbol may decrease the
running count of another reel symbol. For example, a cherry may
cancel an orange. Accordingly, if an orange is a tracked symbol,
and the running count of oranges is twenty. A player receiving an
outcome of CHERRY-7-7 would find his orange balance decreased by
one to nineteen.
[0094] Yet another variation of the rules includes determining
eligibility for bonus payouts based on the accumulation of at least
two different tracked symbol occurrences. In such embodiments
requiring accumulation of different or "complementary" tracked
symbols, it may or may not be desirable to simultaneously employ
the "expiration" functionality discussed herein. Examples and
variations of "complementary symbol" embodiments are disclosed
herein with reference to the "front loading" embodiments and the
food preparation game format.
[0095] A further variation of the rules include modification of
symbol values. In this embodiment, one type of reel symbol may
modify the value associated with another reel symbol. In other
words, one type of reel symbol may reduce or add to (e.g. multiply)
the value of another symbol. For example, the occurrence of a "7"
symbol may serve to reduce the value associated with a cherry
symbol such that the accumulated cherry symbol expires in half the
time that it otherwise would.
[0096] Another variation of the rules includes time periods
(hereafter, "holding periods") for which play must continue after
accumulation of tracked symbols. In other words, the rules may
require that a player not only accumulate certain required symbols,
but also "hold" the symbols for a certain period of time by
continuing play at the slot machine. In such an embodiment
requiring holding periods for tracked symbols, it may or may not be
desirable to simultaneously employ the "expiration" functionality
discussed herein. An example of a holding period rule is discussed
herein with reference to the food preparation game format.
[0097] Yet another variation of the rules includes providing a
bonus payout for achieving a certain combination of tracked
symbols. For example, a bonus payout of fifty coins could be
awarded if each of the running counts is equal to ten
simultaneously. In another example, a bonus payout of fifty coins
could be awarded if a specific running count exactly matched a
required count. The particular number that the running counts would
have to equal could be determined by the casino or selected by the
player using the keypad 342.
[0098] Still another variation of the rules includes displaying
special offers to the player upon achieving a predetermined reward
level. Such offers could include a free night's stay at the casino
hotel, a ticket to a show or other casino event or a free dinner at
the casino restaurant. The offers could be determined by the server
and be based on revenue-management rules in order to optimize the
revenue of the casino. For example, a show starting in a couple of
hours may have a large number of empty seats which the casino would
rather give away than have them remain empty. The server may
determine these offers by checking databases of reservations for
the casino hotel or show. The offers may be made upon achieving the
predetermined reward level (e.g. "Collect 50 Plums to Win a Free
Room!") in place of the monetary award. Alternately, the reward
offers could be made when the player is close to achieving the
sought after balance (e.g. has 48 plums accumulated). Depending on
the reward, it may be more cost effective for the casino to make
the offer rather than pay a monetary reward to the player if he
does get to the sought after level. If the player accepts the
offer, his balance would be reset to zero.
[0099] Video Poker Embodiment
[0100] Many of the disclosed embodiments may be applied to games
such as video poker. As in the slot machine embodiments, in a video
poker embodiment, a player achieves a running count to earn a
reward. The running count is preferably a count of occurrences of
types of cards. A type of card may be a specific card value (e.g.,
aces, twos and threes), a set of card values (e.g., face cards) or
a particular suit (e.g., hearts, diamonds, spades and clubs).
[0101] In the case where the tracked card types are suits, an
exemplary video poker tracked symbol reward table is illustrated as
Table II below. Of course, the expiring nature of the card types
would apply in the same ways as described with respect to the slot
machine embodiments.
2TABLE II Video Poker Tracked Symbol Reward Table Suit Count
Required Bonus Payout Hearts 100 200 Clubs 150 250
[0102] In another embodiment, a running count may be adjusted based
on the numeric card values (e.g., face cards are valued at ten,
aces are valued at eleven). Regardless of what a running count
represents, there are many variations regarding how to adjust the
running count in a video poker embodiment. Specifically, there are
several ways to determine whether an occurrence of a card type has
been generated.
[0103] For example, all cards displayed during a game (including
discarded cards) could be examined to determine whether a card type
occurrence has been generated. In other words, every card displayed
during a game is considered in the decision to adjust the running
count. In an alternate embodiment, the cards examined to determine
whether a card type occurrence has been generated may be limited to
only the cards of the final outcome. In such an embodiment, only
the cards comprising the final hand are considered in the decision
to adjust the running count. In yet another embodiment, only
certain card positions may be examined to determine whether an
occurrence of a card type has been generated. For example, only the
cards displayed in the first card position might be considered in
the decision to adjust the running count. Of course, other ways to
determine occurrences of tracked symbols in a video poker
embodiment are also possible, such as by examining only discarded
cards.
[0104] Food Preparation Game Format
[0105] A game format having a food preparation theme is also
contemplated. In such a game, players are required to accumulate at
least two different or complementary tracked symbols, which may
represent different "ingredients" in a "recipe." In one embodiment,
mere accumulation of the at least two different or complementary
tracked symbols qualifies players for a bonus payout. In another
embodiment, different recipes (i.e. different combinations of
complementary tracked symbols) may yield different bonus payouts.
In such an embodiment, a player may accumulate all tracked symbols
required for a first recipe that yields a first bonus payout, but
may choose to forego the first bonus payout for a chance to win a
second, greater bonus payout that requires further accumulation of
additional symbols.
[0106] For example, a slot machine featuring a "bake the cake" game
format may require players to accumulate (1) two egg symbols, (2)
one flour symbol, (3) two milk symbols and (4) one chocolate
symbol. These symbols may be represented on the reels of the slot
machine. Players accumulating all of these necessary ingredients
are deemed to have completed the recipe for a chocolate cake, and
would therefore qualify for a bonus payout. Alternatively, players
collecting most of the required ingredients could win a somewhat
smaller award. In yet another embodiment, players accumulating all
necessary ingredients required for a bonus payout may be offered
the option to forego the earned bonus payout, and "press their
luck" by continuing the game session with hopes of accumulating
additional ingredients necessary for completion of a different
recipe, which may yield an enhanced bonus payout. For example, in
order to qualify for a greater bonus payout, a player may be
required to accumulate all of the above ingredients, and also fifty
cherry symbols.
[0107] Further, alternative mechanisms are contemplated for dealing
with accumulation of more ingredients than are necessary for a
given recipe. According to one embodiment, if a player has
accumulated enough of a given ingredient for a given recipe, any
remaining ingredients of that type may be eliminated as reel
symbols on the graphical reels of the slot machine. The game device
may replace the ingredient symbol(s) with another reel symbol, or
may simply eliminate the ingredient's reel symbol position and
thereby reduce the number of possible reel stops associated with
that reel by one. According to another embodiment, duplicative
ingredients may be accumulated and applied toward different bonus
prizes (e.g. different recipes or different productions of the same
recipe).
[0108] In such a food preparation game, the rules may be configured
to allow for certain "substitute" ingredients. In such an
embodiment, different reels symbols may be accorded the same status
for purposes of the food preparation game so that, for example,
"bar" symbols are treated the same as "egg" symbols.
[0109] Additionally, a holding period rule may be employed to
require players to hold the accumulated ingredients for a threshold
amount of time in order to qualify for a bonus payout. For example,
in a "bake the cake" game, in order to qualify for a bonus payout,
players may be required to (1) collect (a) two egg symbols, (b) one
flour symbol, (c) two milk symbols and (d) one chocolate symbol;
and (2) thereafter continue playing for at least twenty minutes
(i.e. while the cake "bakes"). Such a holding period rule would
function to further encourage prolonged game play.
[0110] It should be noted that, in an alternate embodiment, a
player may qualify for a bonus payout by promising to satisfy the
"holding period" requirement in the future. In other words, in such
an embodiment, the player could instantly receive the bonus payout
upon collecting all the requisite ingredients and indicating a
promise to play for the required time at some point in the future.
The bonus payout could be rescinded by the casino if the player
subsequently failed to perform by playing for the required amount
of time. For example, the bonus payout could be rescinded by
instituting a charge to the player's credit or debit card in an
amount equal to the bonus payout.
[0111] It should also be noted that, in yet another alternate
embodiment, a game having a food preparation theme may incorporate
a "baking" or "time" component by providing for a clock symbol (or
other symbolic representation of a time element) on the reels of
the slot machine. In such an embodiment, a player may instantly
satisfy the baking time requirement by receiving an outcome having
one or more such reel symbols. In a further embodiment, one or more
reel stop positions may contain an amount of time. For example, one
reel symbol might represent 30 seconds of cooking time while
another reel symbol represents 45 seconds of cooking time. Players
could be required to "collect" 10 minutes of baking time in
addition to collecting all of the necessary ingredients in order to
qualify for the bonus.
[0112] Additional Bonus Game Formats
[0113] Many of the disclosed variations of the invention may be
applied to enable many other bonus game formats. For example, in a
Bingo game format players must collect certain pieces of a game
board in order to win. In such a Bingo embodiment, collected board
positions may expire as discussed above, making it more difficult
for players to win the Bingo bonus game. Similarly, Scrabble .RTM.
and Wheel of Fortune .RTM. game formats are contemplated, in which
players must assemble words from letters generated by game
outcomes. In such an embodiment, collected letters may expire as
discussed above, making it more difficult for players to complete
words and thereby score points in the bonus game.
[0114] Likewise, a video game format is contemplated in which the
object is to break through a representation of a wall, such as the
wall to a bank's vault. Certain game outcomes could result in
destruction of the wall, and expiration as discussed previously
could be represented as the rebuilding of the wall.
[0115] Further, an "egg timer" game format is contemplated in which
players must accumulate visual representations of eggs and continue
playing until they are "cooked" such that each cooked egg is
potentially awarded with a bonus. In such an "egg timer" game, the
prospect of winning a bonus would encourage players to prolong play
until eggs are cooked. It should be noted that such an "egg timer"
game in essence serves to achieve the same purpose as the
above-described "expiration" concept, to wit encouraging players to
play for longer periods of time, but does so by presenting the
time-based requirement as an "affirmative" prerequisite to bonus
eligibility (i.e., the eggs must cook for a predetermined amount of
time) rather than as a "negative" prerequisite to bonus eligibility
(i.e. a threshold number of accumulated symbols must not
expire).
[0116] While the best mode for carrying out the invention has been
described in detail, those familiar with the art to which the
invention relates will recognize various alternative designs and
embodiments for practicing the invention. These alternative
embodiments are within the scope of the present invention.
Accordingly, the scope of the present invention embodies the scope
of the claims appended hereto.
