RELATED APPLICATIONS
[0001] This application claims priority to Australian Patent
Application No. 2008900268, having a filing date of Jan. 21, 2008,
which is incorporated herein by reference in its entirety.
FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
[0002] [Not Applicable]
MICROFICHE/COPYRIGHT REFERENCE
[0003] [Not Applicable]
BACKGROUND OF THE INVENTION
[0004] It is known to provide a gaming system which comprises a
game controller arranged to randomly select and cause the display
of several symbols from a predetermined set of symbols and to
determine a game outcome, such as a game win, based on the
displayed symbols. Such gaming systems may commonly be implemented
as a stepping machine provided with reels with each reel carrying
several symbols of the set, or a video machine wherein selected
symbols are displayed on virtual reels on a graphical display
device. Win outcomes can occur based on symbols appearing in one or
more horizontal lines, diagonal lines, or any other predetermined
way. Typically five reels across are provided on the display
(although less or more may be provided). Each reel or virtual reel
display is three symbols high in the display window for the reel
(although, again, this may be more or less symbols high).
[0005] In many countries, the regulations prescribe that the number
of available symbols to select from be a fixed number. With stepper
reels this is implemented by having a fixed number of symbols on
each reel. With video implementation or other "virtual" reel
implementations this is implemented in a similar manner, by
allowing only a predetermined number of symbols for each virtual
reel. A problem with requiring a fixed number of reel "stops",
whether virtual or stepper, is that this limits the number of
combinations that a typical reel game can provide for entertainment
of the player.
[0006] It is known to provide "feature" games to provide more
opportunities for prize winning and increase entertainment. Whilst
such gaming systems provide users with enjoyment, the need exists
for alternative gaming systems in order to maintain or increase
player enjoyment.

DETAILED DESCRIPTION OF THE INVENTION
[0041] Referring to the drawings, there is shown a gaming system
arranged to implement a game in which a plurality of symbols from a
set of symbols is selected and displayed in symbol positions in one
or both of rows and columns. FIG. 7 shows an example display 400
with symbols 401 displayed in a plurality of rows and columns. In
this embodiment, the gaming system is arranged to select at least
one additional symbol and control a display to display the at least
one additional symbol associated with a strip associated with one
of the symbol positions. In the example of FIG. 7, additional
symbols 402, 403 are shown associated with strip 404. The provision
of additional symbols advantageously enables the gaming system to
offer more combinations of symbols to the player, more chances of
winning a prize, potentially higher value prizes and player
interaction.
[0042] The gaming system can take a number of different forms.
[0043] In a first form, a stand alone gaming machine is provided
wherein all or most components required for implementing the game
are present in a player operable gaming machine.
[0044] In a second form, a distributed architecture is provided
wherein some of the components required for implementing the game
are present in a player operable gaming machine and some of the
components required for implementing the game are located remotely
relative to the gaming machine. For example, a "thick client"
architecture may be used wherein part of the game is executed on a
player operable gaming machine and part of the game is executed
remotely, such as by a gaming server; or a "thin client"
architecture may be used wherein most of the game is executed
remotely such as by a gaming server and a player operable gaming
machine is used only to display audible and/or visible gaming
information to the player and receive gaming inputs from the
player.
[0045] However, it will be understood that other arrangements are
envisaged. For example, an architecture may be provided wherein a
gaming machine is networked to a gaming server and the respective
functions of the gaming machine and the gaming server are
selectively modifiable. For example, the gaming system may operate
in stand alone gaming machine mode, "thick client" mode or "thin
client" mode depending on the game being played, operating
conditions, and so on. Other variations will be apparent to persons
skilled in the art.
[0046] Irrespective of the form, the gaming system comprises
several core components. At the broadest level, the core components
are a player interface 50 and a game controller 60 as illustrated
in FIG. 1. The player interface is arranged to enable manual
interaction between a player and the gaming system and for this
purpose includes the input/output components required for the
player to enter instructions and play the game.
[0047] Components of the player interface may vary from embodiment
to embodiment but will typically include a credit mechanism 52 to
enable a player to input credits and receive payouts, one or more
displays 54, a game play mechanism 56 that enables a player to
input game play instructions (e.g. to place bets), and one or more
speakers 58.
[0048] The game controller 60 is in data communication with the
player interface and typically includes a processor 62 that
processes the game play instructions in accordance with game play
rules and outputs game play outcomes to the display. Typically, the
game play instructions are stored as program code in a memory 64
but can also be hardwired. Herein the term "processor" is used to
refer generically to any device that can process game play
instructions in accordance with game play rules and may include: a
microprocessor, microcontroller, programmable logic device or other
computational device, a general purpose computer (e.g. a PC) or a
server.
[0049] A gaming system in the form of a stand alone gaming machine
10 is illustrated in FIG. 2. The gaming machine 10 includes a
console 12 having a display 14 on which is displayed
representations of a game 16 that can be played by a player. A
mid-trim 20 of the gaming machine 10 houses a bank of buttons 22
for enabling a player to interact with the gaming machine, in
particular during gameplay. The mid-trim 20 also houses a credit
input mechanism 24 which in this example includes a coin input
chute 24A and a bill collector 24B. Other credit input mechanisms
may also be employed, for example, a card reader for reading a
smart card, debit card or credit card. A player marketing module
(not shown) having a reading device may also be provided for the
purpose of reading a player tracking device, for example as part of
a loyalty program. The player tracking device may be in the form of
a card, flash drive or any other portable storage medium capable of
being read by the reading device.
[0050] A top box 26 may carry artwork 28, including for example pay
tables and details of bonus awards and other information or images
relating to the game. Further artwork and/or information may be
provided on a front panel 29 of the console 12. A coin tray 30 is
mounted beneath the front panel 29 for dispensing cash payouts from
the gaming machine 10.
[0051] The display 14 shown in FIG. 2 is in the form of a video
display unit, particularly a cathode ray tube screen device.
Alternatively, the display 14 may be a liquid crystal display,
plasma screen, any other suitable video display unit, or the
visible portion of an electromechanical device. The top box 26 may
also include a display, for example a video display unit, which may
be of the same type as the display 14, or of a different type.
[0052] FIG. 3 shows a block diagram of operative components of a
typical gaming machine which may be the same as or different to the
gaming machine of FIG. 2.
[0053] The gaming machine 100 includes a game controller 101 having
a processor 102. Instructions and data to control operation of the
processor 102 are stored in a memory 103, which is in data
communication with the processor 102. Typically, the gaming machine
100 will include both volatile and non-volatile memory and more
than one of each type of memory, with such memories being
collectively represented by the memory 103.
[0054] The gaming machine has hardware meters 104 for purposes
including ensuring regulatory compliance and monitoring player
credit, an input/output (I/O) interface 105 for communicating with
peripheral devices of the gaming machine 100. The input/output
interface 105 and/or the peripheral devices may be intelligent
devices with their own memory for storing associated instructions
and data for use with the input/output interface or the peripheral
devices. A random number generator module 113 generates random
numbers for use by the processor 102. Persons skilled in the art
will appreciate that the reference to random numbers includes
pseudo-random numbers.
[0055] In the example shown in FIG. 3, a player interface 120
includes peripheral devices that communicate with the game
controller 101 comprise one or more displays 106, a touch screen
and/or buttons 107, a card and/or ticket reader 108, a printer 109,
a bill acceptor and/or coin input mechanism 110 and a coin output
mechanism 111. Additional hardware may be included as part of the
gaming machine 100, or hardware may be omitted as required for the
specific implementation.
[0056] In addition, the gaming machine 100 may include a
communications interface, for example a network card 112. The
network card may, for example, send status information, accounting
information or other information to a central controller, server or
database and receive data or commands from the central controller,
server or database.
[0057] FIG. 4 shows a block diagram of the main components of an
exemplary memory 103. The memory 103 includes RAM 103A, EPROM 103B
and a mass storage device 103C. The RAM 103A typically temporarily
holds program files for execution by the processor 102 and related
data. The EPROM 103B may be a boot ROM device and/or may contain
some system or game related code. The mass storage device 103C is
typically used to store game programs, the integrity of which may
be verified and/or authenticated by the processor 102 using
protected code from the EPROM 103B or elsewhere.
[0058] It is also possible for the operative components of the
gaming machine 100 to be distributed, for example input/output
devices 106,107,108,109,110,111 to be provided remotely from the
game controller 101.
[0059] FIG. 5 shows a gaming system 200 in accordance with an
alternative embodiment. The gaming system 200 includes a network
201, which for example may be an Ethernet network. Gaming machines
202, shown arranged in three banks 203 of two gaming machines 202
in FIG. 5, are connected to the network 201. The gaming machines
202 provide a player operable interface and may be the same as the
gaming machines 10,100 shown in FIGS. 2 and 3, or may have
simplified functionality depending on the requirements for
implementing game play. While banks 203 of two gaming machines are
illustrated in FIG. 5, banks of one, three or more gaming machines
are also envisaged.
[0060] One or more displays 204 may also be connected to the
network 201. The displays 204 may, for example, be associated with
one or more banks 203 of gaming machines. The displays 204 may be
used to display representations associated with game play on the
gaming machines 202, and/or used to display other representations,
for example promotional or informational material.
[0061] In a thick client embodiment, game server 205 implements
part of the game played by a player using a gaming machine 202 and
the gaming machine 202 implements part of the game. With this
embodiment, as both the game server and the gaming device implement
part of the game, they collectively provide a game controller. A
database management server 206 may manage storage of game programs
and associated data for downloading or access by the gaming devices
202 in a database 206A. Typically, if the gaming system enables
players to participate in a Jackpot game, a Jackpot server 207 will
be provided to monitor and carry out the Jackpot game. A loyalty
program server 212 may also be provided.
[0062] In a thin client embodiment, game server 205 implements most
or all of the game played by a player using a gaming machine 202
and the gaming machine 202 essentially provides only the player
interface. With this embodiment, the game server 205 provides the
game controller. The gaming machine will receive player
instructions, pass these to the game server which will process them
and return game play outcomes to the gaming machine for display. In
a thin client embodiment, the gaming machines could be computer
terminals, e.g. PCs running software that provides a player
interface operable using standard computer input and output
components.
[0063] Servers are also typically provided to assist in the
administration of the gaming network 200, including for example a
gaming floor management server 208, and a licensing server 209 to
monitor the use of licenses relating to particular games. An
administrator terminal 210 is provided to allow an administrator to
run the network 201 and the devices connected to the network.
[0064] The gaming network 200 may communicate with other gaming
systems, other local networks, for example a corporate network,
and/or a wide area network such as the Internet, for example
through a firewall 211.
[0065] Persons skilled in the art will appreciate that in
accordance with known techniques, functionality at the server side
of the network may be distributed over a plurality of different
computers. For example, elements may be run as a single "engine" on
one server or a separate server may be provided. For example, the
game server 205 could run a random number generator engine.
Alternatively, a separate random number generator server could be
provided. Further, persons skilled in the art will appreciate that
a plurality of games servers could be provided to run different
games or a single game server may run a plurality of different
games as required by the terminals.
[0066] Referring to FIG. 6, the functionality of embodiments of the
present invention may be implemented by a game controller having
the functional components illustrated. In this embodiment, the
functional components are implemented utilizing a processor and
memory (such as processor 102 and memory 103 in FIG. 3, or
processor 62 and memory 64 in FIG. 1, for the game server 205 in
FIG. 5), and associated programming. Other implementations are
envisaged. For example the functional blocks of FIG. 6 may be
implemented in hardware as separate units, or a combination of
hardware and software as separate units. Any practical
implementation of these functional units may be employed.
[0067] In this embodiment, the game controller 300 is arranged to
control the gaming system to play a game which comprises selection
of a plurality of symbols from a set of symbols. The game is
implemented as a "reel" game. The game controller 300 comprises a
display controller 301 which is arranged to control the display
(reference numerals 54, 14, 106, 204 of previous figures) to
emulate a representation of reels bearing symbols. Alternatively,
the display may comprise a stepper motor and physical reels bearing
the symbols.
[0068] The game controller 300 includes a symbol selector 302 which
is arranged to select a plurality of symbols from a set of symbols
available in a symbol store 303. An outcome generator 304 is
arranged to determine an outcome of the game. In this embodiment,
the outcome of the game depends on the selected symbols and the
rules of the game and may include a win outcome, loss outcome,
trigger outcome, a feature outcome or other outcome. Outcomes may
be determined on the basis of symbols appearing in one or more
horizontal lines, diagonal lines, or any other pre-determined
combinations.
[0069] FIG. 7 shows a representation of a gaming machine display
400 which, in the example shown, has five reels (numbered "1" to
"5"). The display 400 shows three reel positions high when the
reels have stopped / the symbols have been selected. The reel
positions are designated Bottom ("B"), Centre ("C") and Top ("T").
This is a typical reel-type display for a gaming machine. It will
be appreciated that in other embodiments the number of reel
positions may be more or less than in display 400. Also the number
of reels may be more or less than in the display 400.
[0070] The reels may be virtual reels, generated as a video display
from the selected symbols, actual mechanical reels carrying the
symbols and driven by a stepper motor, or any other reel
arrangement or emulation. In the case of actual physical reels, the
game controller randomly selects the symbols and drives the stepper
motor to display the selected symbols appearing in the display
400.
[0071] The game outcome is determined by the outcome generator 304
based on combinations of symbols selected and appearing in the
display 400. The symbols may be any symbols. As will be
appreciated, many different types of symbols are used in gaming
systems. A set of symbols may include standard symbols and function
symbols. For example, standard symbols may resemble fruit such as
apples, pears and bananas with a win outcome being determined when
a predetermined number of the same fruit appear on a display in the
same line, scattered, and so on. The function associated with a
function symbol may be a "wild" function wherein display of the
function symbol is treated during consideration of the game outcome
as any of the standard symbols. Other functions may include scatter
functions, multiplier functions, repeat win functions, jackpot
functions and feature commencement functions.
[0072] In the example shown in FIG. 7, the symbols are
representations of cards, by which a poker-type card game may be
played. In this example, a winning poker hand appearing on the C
line may cause the outcome generator to determine that a Win has
occurred and that an appropriate prize may be awarded. For example,
five of a kind (e.g. 5 jacks "J". 5 tens "10" etc) on the C line
may result in a win. A straight or a straight flush or any other
poker combination on the C line may also result in a win.
[0073] In addition to card symbols, the symbols also include a Wild
"W" symbol which is a function symbol which, when it occurs on the
C line may be considered by the outcome generator 304 to operate as
any symbol which may assist in a win. Symbols may also include
jackpot symbols. For example, five Aces "A" symbols appearing on
the centre line C may result in a jackpot win.
[0074] The diagram shown in FIG. 7 is one way of representing the
symbols only. It will be appreciated that in other embodiments of
the invention the symbols may be represented in different ways,
using any type of fancy artwork, or in any appropriate manner.
[0075] Operation of an embodiment of the present invention will now
be described with reference to FIGS. 7 and 8.
[0076] Referring to FIG. 7, the symbol selector 302 selects a
plurality of symbols from symbols available from the symbol store
303. The game controller 300 operates via a display controller 301
to emulate spinning of reels in the display 400. Selected symbols
401 are "spun up" on the reels. This is how a conventional video
animated reel spinning game operates. A game outcome is determined
by the outcome generator 304 depending upon line or scatter
combinations (or other features, such as bonus awards) of the
symbols appearing in the display 400.
[0077] With this basic reel game, however, there are limited number
of symbol combinations available. In this embodiment of the
invention, in order to provide further opportunities for awarding
of prizes to players, the game controller 300 is also arranged to
select additional symbols which can be incorporated with the
selected symbols to provide additional opportunities for
combinations which may lead to prize winning results.
[0078] Referring to FIG. 7, the game controller 300 selects
additional symbols, in this case in the form of two jacks "J" 402,
403. The additional symbol selection is represented graphically to
the player on the display 400 in an interesting way, associated
with a "strip" 404. The strip 404 appears as though it has been
peeled away from the reel. The underside of the strip shows one
additional symbol "J" 403 in mirror image form. An additional
symbol "J" 402 appears on a revealed symbol position 405 on the
reel.
[0079] Calculating combinations available, the outcome generator
304 may consider the symbol "J" 403 to be present on the centre
line C of the mirror display 400. The symbol "J" 402 is considered
to be present on the bottom line B of the reel display 400. A
number of further potential combinations are therefore provided for
determination of an outcome of the game. As well as the King "K"
symbol on the centre row the symbol "J" 403 is considered to be on
the centre row C. Further, a new symbol "J" 402 is considered to be
on the bottom row.
[0080] Prior to the strip 404 being peeled, a selected symbol is
present on the upper side (not shown) of the strip 404 in position
B3 in the reel display 400. This symbol may be the same or
different from the "J" symbols revealed by peel of the strip
404.
[0081] In this embodiment, it is available to the game controller
300 to make combinations from all the symbols that have been
selected, including the originally selected symbols and the
additional symbols. It may do this by first determining
combinations and outcomes for the originally selected symbols, then
doing the same including the additional symbols in the
combinations. The outcome determinations may be made sequentially
or simultaneously.
[0082] In this embodiment, the chance to obtain a "peel" (i.e. the
chance for a player to obtain one or more additional symbols) may
be "bought" by the player entering extra credit or may be awarded
as an outcome of the selection of the original symbol set.
[0083] For example, a scatter of four Queens "Q" symbols as shown
in FIG. 7 may result in the awarding of a peel to the player.
Alternatively two wild cards "W" symbols appearing in the display
400 may be a trigger leading to a peel, or any other trigger
combination determined by the game designer.
[0084] A player may "buy" a peel by entering additional credit.
This rewards a player who is willing to place higher bets, by
giving them additional symbols and therefore more chances to win
prizes.
[0085] The ability to buy additional symbols can address a
perceived problem with the winning of the jackpots. A jackpot game
may apply to a stand alone game machine or may be a "linked
jackpot" to which a number of machines contribute. A jackpot prize
is only won when a particular combination of indicia is achieved on
one of the machines (or the machine if it is a stand alone machine)
e.g. five Aces in a line.
[0086] A problem with such jackpots is that the winning of a
jackpot is generally independent of the number of credit units
wagered by a player. Players who are willing to bet more credits to
win a jackpot e.g. more credits per line, have as much chance as a
player who is only willing to bet a small number of credits per
line, of winning the jackpot. This is perceived as being unfair to
players who are willing to gamble higher (in order to win the
jackpot) than other players.
[0087] In this embodiment of the credits, a player who bets more
credits may receive one or more additional symbols in the form of
"peels" giving him additional chances to obtain jackpot symbols,
for example, and therefore a better chance of winning the
jackpot.
[0088] The present invention is not limited to providing additional
symbols and giving additional chances to win jackpots, however.
Because additional symbols are provided, additional combinations
for winning any prize, bonus, feature etc may be achieved.
[0089] A peel may be awarded to a player on the basis of other
criteria than the amount of player credit. Other triggers may
include a measurement of time that the player has been playing the
machine, a particular amount of waiting activity on the machine, it
may be based on player tracking information or may be a random
event or any other trigger.
[0090] Another example display is shown in FIG. 8. In this
embodiment there are two strips available for peel, 404A and 404B.
For strip 404A, additional symbols include those revealed when the
strip is peeled, symbols 402A (being "10" "K" and "J"symbols). Also
the symbols 403A on the underside of the strip (a "10", "K" and "J"
also). There are therefore three additional symbols in rows T, C
and B ("10", "K" and "J" respectively. The symbols 403A on the
underside of the strip 404A may all be considered as taking the top
row T position (i.e. "10", "K" and "J" in the top row). This
provides for several more potential combinations in the top row
T.
[0091] In reel 2, another strip is available for peel, strip 404B.
This strip 404B reveals two additional symbols 403B. A queen "Q" is
revealed on the centre row C, and a Jack "J" (on the underside of
the strip 404B) can be considered to take a place in the top row T
with the Ace symbol "A" already present.
[0092] In the above embodiment, additional symbols may be present
on the underside of the strip and also revealed on the reel strip
once the strip has been removed. As discussed above, account may
also be taken, when determining outcomes, of the symbols that
originally appeared on top of the strip (i.e. the originally
selected symbols). It will be appreciated that account need not be
taken of the originally appearing symbols. This will be up to the
game designer who sets the rules. In the above embodiment, the
strip is associated with a symbol position. For example, the strip
404B is associated with the reel position 2C. This is the reel
position from which it is peeled away. Similarly with strip 404A,
which is associated with reel position T3 (the reel position to
which the strip is still connected). In other embodiments, the reel
strip may be associated with other positions, particularly where
there is more than one additional symbol on the underside of the
strip. For example, in the embodiment of FIG. 8 and strip 404A, all
three additional symbols 403A on the underside of the strip 404A
are considered to be in the top row T. In an alternative
embodiment, each symbol may be considered to be in a different row.
For example, a "10" may be in the top row, "K" may be considered to
be in the middle row, and "J" may be considered in the bottom row.
Variations to the positions taken by the additional symbols may be
determined by the game designer and included in the rules of the
game.
[0093] In the above embodiment, the strips are peeled from a single
reel and the additional symbols are considered to be added to the
reel. In another embodiment, the reel strip may peel across a row
and the additional symbols may be considered to be present in
adjacent row positions.
[0094] In the above embodiment, the strip is represented in an
interesting graphic which appears to have been peeled away from a
reel. The invention is not limited to this representation. The
strip may be represented as any type of substrate mounting symbols
or revealing symbols on the reel strip underneath. It need not
necessarily be shown connected to the reel but may be removed from
it on a different part of the display. An indicator may indicate
which symbol positions the symbols are associated with and which
symbol positions the strip is associated with.
[0095] In an embodiment, the player interface may enable player
manipulation or actuation to allow the player to activate the peel.
This could be done in any number of ways, for example by touch
screen, or a button on the gaming machine.
[0096] The player may have the choice as to whether or not to avail
themselves of the additional symbols, or the gaming system may make
the choice for the player.
[0097] A game playing process in accordance with an embodiment of
the present invention will now be summarized with reference to FIG.
9.
[0098] At step 700 the game is played by selection of symbols from
a symbol store 303 by the symbol selector 302. At step 701 a
determination is made as to whether or not any additional symbols
are available to be allocated to the player ("peel available?"). As
discussed above, additional symbols may be made available depending
on any number of predetermined criteria, including whether the
player has entered credits to "buy" additional symbols. If a peel
is available, at step 703 the game controller 300 selects
additional symbols. If no peel is available, the game outcome is
determined at step 703 on the basis of only the originally selected
symbols. Where additional symbols have been selected, the next step
is to determine the game outcome based on the originally selected
symbols (step 700) and the additional symbols (step 702).
[0099] In the above described embodiments, the display emulates a
plurality of reels. In an alternative embodiment, the original
symbol selection may be implemented as actual reels driven by a
stepper motor. The additional symbols may be added by video
graphics overlaying the display of the actual stepper reels. In
another embodiment, the display may not emulate reels but merely
show the selected symbols in a non-reel format e.g. presenting them
as emulated playing cards, or other graphical representations of a
series of rows and columns.
[0100] In the above embodiments, a single strip is attached to or
associated with a symbol position. In another embodiment , more
than one strip may be associated with a single position. In this
embodiment, the graphical representation may show two or more
strips being peeled away from an associated symbol position.
[0101] In the claims which follow and in the preceding description
of the invention, except where the context requires otherwise due
to express language or necessary implication, the word "comprise"
or variations such as "comprises" or "comprising" is used in an
inclusive sense, i.e. to specify the presence of the stated
features but not to preclude the presence or addition of further
features in various embodiments of the invention.
[0102] It will be appreciated by persons skilled in the art that
numerous variations and/or modifications may be made to the
invention as shown in the specific embodiments without departing
from the spirit or scope of the invention as broadly described. The
present embodiments are, therefore, to be considered in all
respects as illustrative and not restrictive.
