FIELD OF THE INVENTION

The present invention relates to a gaming system, a method of gaming, a game controller and computer program code.

BACKGROUND OF THE INVENTION

It is known to provide a gaming system such as a video slot machine wherein symbols are displayed as a plurality of virtual reels on a video display. Each reel comprises a plurality of symbols arranged in a predetermined sequence. Typically, when a reel stops, a plurality of symbols of each reel are visible on the display. For example, three symbols of each reel. While the stopping position of the reel can be chosen in a number of different ways, in all cases, the symbols which stop in the display define a 2-dimensional display array having a width x defined by the number of reels and a height y defined by the number of symbols of the reel that are displayed. For example, in a three reel slot machine, the displayed array would have a width x of three symbols (one for each reel) and a height y of three symbols defining a 3×3 two-dimensional array of nine symbols. As is known in the art “symbols” can include images, numbers, e.g. a “7”, letters or can be “blanks” (no image, number or letter).
The array also provides symbol arrangements which can be defined by pay lines. Historically only one pay line was used which was the horizontal centerline through the array. Later, three pay lines were used defined by the three horizontal line through the array. Modernly more pay lines such as diagonals and reflecting lines through the array have been used. Players wager upon pay lines and when an outcome arranged along a wagered upon pay line corresponds to a predetermined winning symbol arrangement such as, for example, three 7s, the player is issued an award.
While such gaming systems provide users with enjoyment, a need exists for alternative gaming systems in order to maintain or increase player enjoyment.

DETAILED DESCRIPTION OF THE EMBODIMENT

The embodiment provides a gaming system having a game controller that implements a game where a game outcome is generated by selecting a plurality of symbols that are displayed at a plurality of display positions in a three-dimensional array. It is determined whether a game outcome includes a winning outcome corresponding to a player selection. For example, in one embodiment, a player selects pay lines to play from a plurality of pay lines. The pay lines are arranged such that at least one pay line extends through the array. Thus, there are pay lines in at least two different planes or sub-arrays.

Forms of Gaming Systems

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.
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.
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.
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 50 is arranged to enable interaction between a player and the gaming system and for this purpose includes the input/output components required for the player to enter instructions including selections and play the game.
Components of the player interface 50 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, and a speaker 58 for audio outputs.
The game controller 60 is in data communication with the player interface 50 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.
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 video display 14 on which is displayed representations of a game 16 that can be played by a player, such as the game of the embodiment. 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 game play. The mid-trim 20 also houses a credit input mechanism 24 which in this example includes a coin input chute 24A and a bill validator 24B. Other credit input mechanisms may also be employed, for example, a card reader for reading a smart card, debit card or credit card or credits may be electronically downloaded from an account such as described in U.S. Pat. No. 6,511,377 the disclosure of which is hereby incorporated by reference. A player marketing module may be provided 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.
A top box 26 may carry artwork 28, including for example game 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.
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. 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.
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.
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. Memory 103 also stores data,—for example, in a data structure—corresponding to the game symbols or indicia for the game. “Symbols” as used in this specification includes images which may be pictures, numbers, icons, letters or other indicia used for the play of the game as hereinafter described. Memory 103 may also store winning symbol arrangements and awards which are used to determine when the player obtains a winning, outcome and the award for each winning outcome.
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. The random numbers selected are processed by the processor 102 with data from the memory 103 to randomly select and display the outcomes of symbols for the game as hereinafter described. In an embodiment, a 3D graphics card 114 may be used to render the depiction of the three-dimensional array on the display 14 or one or more of the provided displays 106.
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 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.
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.
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.
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.
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.
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.
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 carry out the accounting in respect of the Jackpot game. A loyalty program server 212 may also be provided.
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.
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.
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.
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 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.
As indicated above, in the embodiment the three-dimensional array of symbols is formed by displaying selected symbols at respective ones of a plurality of symbol positions. In the embodiment, the processor 62 randomly selects the symbols and controls the display 16 to display the symbols in a three dimensional array as exemplified by FIGS. 8-10.
The game controller 60 of the embodiment is shown in more detail in FIG. 6. It will apparent that the processor 62 implements a number of modules, for example random number generator module 621 by executing software routines. Persons skilled in the art will appreciate that not all modules need be implemented by processor 62. For example, the random number generator module 621 could be implemented by a separate circuit or by a random number generator server.
The outcome determiner 622 of game controller 60 selects symbols by employing a stop selector 622A that randomly determines the stop position for each virtual reel using random numbers from random number generator 621. Data corresponding to each virtual reel is configured to represent the arrangements of symbols as they would be displayed. Symbol data 641B stored in memory 64 represents each reel and the sequence of the symbols as they would appear on a reel strip if the virtual reel were a physical reel, e.g. a “7” is above a “Blank” and below a “Cherry”. For example, if there are nine reels, each having twenty symbols (sometimes referred to as stops) the random number generator and stop selector 622A might determine that a series of stop positions are positions: 3, 13, 7, 9, 1, 7, 14, 10 and 17—i.e. to particular positions in the sequence of the symbols. These are then mapped to symbols such that the selected symbols for a centre line position in the display 16 for each reel are, for example, a 7, Blank, Bar, Bar-Bar, Wild, Blank, Blank respectively the display 16 is controlled to display the selected symbols at the centre line position with the symbols from each virtual reel as mapped above and below those symbols. Each symbol or stop position may have a weighting as suggested in Telnaes, U.S. Pat. No. 4,448,419, the disclosure of which is incorporated by reference.
In an alternative embodiment the random number generator may select random numbers which result in the placement of a symbol at each position in the matrix array departing from the concept of virtual reel strips.
As in normal spinning reel games, the game controller 60 is adapted to receive an instruction from the player interface 50 from a player which enables a player to make a selection which affects the player's entitlement to win (a “win entitlement”). In one example, a players win entitlement may be based on how many pay lines they will play in each game—i.e. a minimum of one pay line up to the maximum number of pay lines allowed by the game (noting that not all permutations of win lines may be available for selection). The player operates pay line selector 56A of the instruction input mechanism 56 in order to select the number of pay lines. In many games, the players win entitlement is not strictly limited to the lines they have selected, for example, “scatter” pays are awarded independently of a player's selection of pay lines and are an inherent part of the win entitlement. The increased number of display positions provided by three dimensional arrays relative to two dimensional arrays of the same dimensions, as described herein, provides additional options in game pay lines, game design and game play.
Persons, skilled in the art, will appreciate that in other embodiments, the player may obtain a win entitlement select a number of reels to play such as described in Bennett, U.S. Pat. No. 6,063,102 titled “ Multiline Gaming Device” the disclosure of which is hereby incorporated by reference. Some pay arrangements may be formed by a set of symbol positions made up of symbols from different reels making such arrangement a type of structured “scatter” pay where there are nm possible pay arrangements in a two dimensional array where n=number of rows in the array and m=number of columns(reels). This scatter pay arrangement may be used in lieu of pay lines in some embodiments; however due to the number and complexity of pay arrangements which would be defined thereby, a pay line configuration is advantageous. In other embodiments a player win entitlement may be defined by purchasing access to particular pay tables—e.g. a first bet amount entitles the player to wins including cherries and a second amount entitles them to wins including plums. The win entitlement is not always purchased—e.g. a series of free games may be awarded to a player.
The win entitlements which can be purchased are usually advertised to the player by markings on the display, for example by or diagrams showing the symbol positions that correspond to each pay line. Typically, the pay lines will be constituted by symbol positions in the visible window. A win outcome is determined based on the selected symbols of a game outcome and a player's win entitlement and a pay table that specifies awards.
Unlike conventional gaming machines, in the embodiment, the 3D display controller 623 displays symbol data in a three dimensional array which includes three sub-arrays depicted as planar, two-dimensional, 3×3 matrices of three-dimensionally rendered symbols stacked vertically one above the other as illustrated in FIGS. 8 to 10.
Starting with the example of FIG. 8A, it will apparent that the display controller is arranged to display 16, at least in the example of FIG. 8A, twenty seven different symbol positions as defined by three, 3×3, sub-arrays 840, 850 and 860. It will be apparent from the perspective view of FIG. 8A that all of these symbol positions may not be visible at one time, in particular, the symbols in the lower plane 860 are initially obscured by symbols of the middle plane 850. Persons skilled in the art will appreciate that various display techniques will be available in order to display all the symbols, including making part of the display transparent or “ghost-like” during part of the display routine or rotating the symbol display, spacing the sub-arrays 840,850 and 860 or providing an auxiliary display (e.g. on a display in the top box 26) showing each of the sub-arrays in plan view. In each of FIGS. 8 to 10, a common convention is used to designate the three axes of the three dimensional array of display positions of symbols. As indicated by reference axis 805, the two horizontal axis are designated the X and Y axis and the vertical axis is designated the Z axis.
Each sub-array 840, 850 and 860 is depicted as a 3×3 matrix of symbols as would be displayed in a familiar, virtual, 3-reel slot machine. Thus each sub-array 840, 850 and 860 presents 9 symbol positions defined by three rows of symbols for each of three reels (in the X axis). The reels for one sub-array may be rotated 90 degrees relative to an adjoining sub-array. For example, sub-array 849 may have its reels arranged rotated 90 degrees relative to the reels of sub-array 850. In the embodiment the reels for all sub-arrays 840,850, 860 are arranged to spin in the same direction.
It will also be appreciate that the 3D display controller 623 may be arranged to display the reels as spinning in the direction of the z axis. Further, other techniques may be used to display the symbols locating in the display position without displaying reels or the like. For example, it is possible to individually select the symbols for each position and individually populate each of the display positions.
Referring to FIG. 8A, it will be apparent that the three dimensional array 800A shown in FIG. 8A is displayed in a perspective view in order to maximise the number of display positions that are visible.
As shown in FIG. 8A each sub-array 840,850,860 includes five pay lines 820 (shown in sub-array 840 only in FIG. 8A). FIG. 8B illustrates the pay lines that are available in the middle sub-array 850 as exemplified by pay line 820. FIG. 8C shows the pay lines in the bottom sub-array 860 as exemplified by pay line 825. The pay lines lie in the individual sub-arrays. Thus, in the depicted embodiment, 3×5=15 pay arrangements are shown.
FIGS. 9A to 9C illustrate a like number of pay lines that pass through vertical planes 910, 920 and 930 respectively defined in the array 800A and which include symbols from tow or more, in this case all three, sub-arrays 840,850, 860. Thus the vertical arrangement of pay lines in FIGS. 9A-9C shows another 3×5=15 pay lines.
Persons skilled in the art will appreciate that other pay lines are possible, for example an additional pay line could extend diagonally so that it passes through each sub-array 840,850,860 and each vertical plane. It is also possible to have pay lines that reflect through the three-dimensional array 800A to include symbols from different sub-arrays 840,850,860. However, it will be appreciated that irrespective of the embodiment, there will be pay lines in at least two different sub-arrays 840,850,860.
Persons skilled in the art will appreciate that it is not strictly necessary to employ both horizontal and vertical planes in the same embodiment, although it is advantageous to do so.
FIG. 10A to 10F illustrate that the pay lines can be represented in different ways in that the display positions can be different. It can be apparent from FIGS. 10A to 10F that the displays 1000A to 1000F can take the form of cubes rather than the open lattice type display of FIGS. 8 and 9. Win lines can extend through horizontal planes as indicated by win lines 1010A to 1010E and these planes can be transverse to one another as indicated by win line 1010F. Shading 1015 to 1019 can be used to highlight different pay lines.
Once the symbols have been displayed at all the relevant positions under control of a 3D display controller, the prize evaluator 622B determines whether the symbols in their symbol positions (given the win entitlement of the player) result in the awarding of any prize based on the prize data 641B. The prize evaluator 622B may compare the symbols selected and displayed in any arrangement selected by the player to be wagered upon. If the symbols for any wagered upon lines compares with a predetermined winning combination, the player is awarded a prize.
Various other embodiments will be apparent to persons skilled in the art, for example, the 3×3 array of FIGS. 8 to 10 can readily be extended to a 4×4 array. Further, while in the exemplary embodiment there are no purely vertical pay lines—i.e. which extend in a direction along the Z axis, vertical pay lines could be used in some embodiments. Further, the invention can be extended to rectangular prisms of display positions. For example, a 5×3×3 three-dimensional array.
The method of the invention is summarised as illustrated in FIG. 7 where a pay line selection is received 710, symbols are selected 720, they are displayed in a three dimensional array 730 and prizes are evaluated from the player's selection of pay lines and the symbol patterns on those pay lines.
In this respect, persons skilled in the art will appreciate the prize evaluation may be in accordance with techniques known in the art.
Persons skilled in the art will also appreciate that the bets may relate to the lines that are available.
It should also be noted that scatter pays may also result in an award if certain symbols should occur, for example, in any position in each of the sub-arrays 840,850,860.
Other features found in conventional gaming machines including feature trigger symbols and the like may be applied. Further, the size of the three dimensional array could vary during game play. For example, a player may initially start with a two dimensional array of symbols but acquire a second two dimensional array of symbols or have the symbols expanded to a 3×3 matrix in response to a trigger event occurring. Such a trigger event may be in accordance with techniques known in the art including the occurrence of a particular symbol in the base game, the payment of an additional bet or trigger based on turnover or games played.
Other variations will be apparent to persons skilled in the art. As but an example, symbols from one or several of the arrays may be used as substitute or additional symbols for a main game array to define additional winning outcomes. For example, the array 840 may represent a primary array. Symbols at corresponding locations in arrays 850 and/or 860 may be used to replace certain symbols at the primary array 840. For example, if either array 850 or 860 displays a wild symbol, that wild symbol may be displayed as migrating to the primary array 840 to define additional winning symbol arrangements. In this fashion the symbols at arrays 850 or 860 may be used to define multipliers or otherwise change the award as produced in the primary array 840.
Other variations would be apparent to persons skilled in the art and should be considered as falling within the scope of the invention described herein.
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.
It is to be understood that, if any prior art publication is referred to herein, such reference does not constitute an admission that the publication forms a part of the common general knowledge in the art in any other country.
