11922758
The present invention relates to a gaming system, a method of gaming, a game controller and computer program code.
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.

The game controller further awards game credit based on a second outcome displayed in the three-dimensional array of display positions. In some embodiments, a winning outcome is determined based on symbols of the second outcome and their relationship to pay lines that pass through one or more two-dimensional arrays of the display positions.
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
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
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
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 (110) 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
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.
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.
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
The game controller 60 of the embodiment is shown in more detail in
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
Starting with the example of
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
As shown in
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.
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
The method of the invention is summarised as illustrated in
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 (
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.
