General Construction of Gaming System
The gaming system can take a number of different forms. 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 has 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 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 including one or more input devices that enable a player to input game play instructions (e.g. to place a wager), and one or more speakers 58. The player interface may also comprise one or more input devices to allow a player to interact with the player interface. The input devices may comprise a touch screen display or one or more buttons or both.
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 rules 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. That is a processor may be provided by any suitable logic circuitry for receiving inputs, processing them in accordance with instructions stored in memory and generating outputs (for example on the display). Such processors are sometimes also referred to as central processing units (CPUs). Most processors are general purpose units, however, it is also know to provide a specific purpose processor using an application specific integrated circuit (ASIC) or a field programmable gate array (FPGA).
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 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 mounted on a circuit board. 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.
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.
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 bonus controller, central controller, server or database and receive data or commands from the bonus controller, central controller, server or database. In embodiments employing a player marketing module, communications over a network may be via player marketing module—i.e. the player marketing module may be in data communication with one or more of the above devices and communicate with it on behalf of the gaming machine.
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. For example, the displays 204 may 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 perform accounting functions for 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. Other client/server configurations are possible, and further details of a client/server architecture can be found in WO 2006/052213 and PCT/SE2006/000559, the disclosures of which are incorporated herein by reference.
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 system 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 game 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.
Further Detail of Gaming System
Referring to
That is, the display 56 comprises a plurality of selectable symbol display positions 600. The symbol display positions 600 can comprise a n×m grid of symbol display positions. The n×m grid can be any sized grid. In the example of
The player can select one or more windows that define a subset of the symbol display positions provided the player's selection complies with game rule 841. The player can select a window through placing a wager. In one embodiment, to form the wager, the player initially indicates how many windows they wish to place over the symbol display positions. The window or windows are then displayed on the display 56 and the player operates one or more input devices to position the windows relative to the symbol display positions. For example, a window may be displayed as a touchable window on a touch screen display and the player may drag the object to a desired position relative to the symbol display positions. In another embodiment, the player could operate arrow buttons to position the windows. The player interface 50 allows the player to select which window to move when there are plural windows, for example by providing a button that allows a player to cycle through individual windows.
In some embodiments, in addition to specifying the window to apply, the player may also select a win entitlement to be evaluated in respect of the window. In other embodiments, the win entitlement may be fixed. In some embodiments, the gaming system may allow different win entitlements to be selected and applied to different windows. In other embodiments, the same win entitlement may apply to all windows.
It will be appreciated, that as the player makes choices, a wager will be built, typically in a number of credits and displayed to the player. The player may adjust their selection of windows and/or win entitlement in order to adjust the wager.
In other embodiments, a player may decide on a wager amount which affects what selections of windows and win entitlements are available.
The win entitlement may be selected from those known in the art. Persons skilled in the art will appreciate that a player's win entitlement may vary from game to game dependent on player selections. In one example, a player's win entitlement may be based on how many lines they play in each game—e.g. a minimum of one line up to the maximum number of lines allowed by the game (noting that not all permutations of win lines may be available for selection) and how much they wager per line. Such win lines are typically formed by a combination of symbol display positions, one from each reel, the symbol display positions being located relative to one another such that they form a line.
In many games, the player's 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.
Persons skilled in the art will appreciate that in other embodiments, the player may obtain a win entitlement by selecting a number of “reels” to play and an amount to wager per reel. Such games are marketed under the trade name “Reel Power” by Aristocrat Leisure Industries Pty Ltd. The selection of the reel means that each displayed symbol of the reel can be substituted for a symbol at one or more designated display positions. In other words, all symbols displayed at symbol display positions corresponding to a selected reel (or column) can be used to form symbol combinations with symbols displayed at a designated, symbol display positions of the other reels. For example, if in a window, there are fifteen symbol display positions, arranged in a five by three grid, the symbols displayed in the centre row are used for non-selected reels/columns. As a result, the total number of ways to win is determined by multiplying the number of active display positions of each column, the active display positions being all display positions of each selected column and the designated display position of the non-selected columns. As a result for five columns and fifteen display positions there are 243 ways to win.
Once a player has chosen to apply a win entitlement and window selection in one play of the game, the player may choose to apply the same wager (and hence selections) in a following play of the game. For example, by pressing a “play again” button.
Once the player initiates a play of the game, the game controller 60 generates a game outcome which will then be evaluated by outcome evaluator 823. The first part of forming the game outcome is for a symbol selector 822 to select symbols from a set of symbols specified by reel data 843 using random number generator 821. The selected symbols are advised to the display controller 825 which causes them to be displayed on display 54 at the set of display positions 60.
One example of selecting symbols is for the symbol selector 822 to select symbols for display from a plurality of symbol sets corresponding to respective ones of a plurality of spinning reels 843 specifying a sequence of symbols for each reel. In the embodiment, individual reels are associated with each display position, and the symbol selector selects a stopping position for each of the reels. In the example of
In another embodiment, reels may be associated with a row or column such that the symbol selector 822 can select all of the symbols for a row or column by selecting a stopping position in the sequence such that the displayed symbols are determined from the symbol at the stopping position and those symbols that neighbour it. It is known to use a probability table stored in memory 64 to vary the odds of a particular stop position being selected. Other techniques can be used to control the odds of particular outcomes occurring to thereby control the return to player of the game.
As shown in relation to
The number of windows that can be selected may be dependent on several criteria. The main criterion for the number of windows selected is dependent on the amount of credits the player wagers or spends. For example a player can buy more for windows for more credits. The amount of windows that can be selected or bought may also be limited by the available symbol display positions within the display area 600. The game controller 60 is arranged to control the amount of windows a player can select based on game rules 841
The player can buy and select multiple windows within the display area. The player selects additional windows by wagering more credits, i.e. buying more windows.
The player can move the position of a selected window 700, 701, 702, 703 around the display area. The window can be moved to define a different subset of symbol display positions.
In one example the player can change the size of the selected window by touching and dragging the corner of the selected window.
The one or more selected windows 700, 701, 702, 703 can be positioned adjacent or spaced from or intersecting with or wholly within the other one or more selected windows 700, 701, 702, 703. In one example one window can be positioned adjacent another selected window, e.g. windows 702,703 in
The size and the allowable position of the windows can be controlled by a set of rules defined and implemented by the controller. The controller can restrict the size and position of the windows depending on the available symbol display positions and depending on the game rules 841. For example, the size of the window may be required to be smaller than the size of the set of symbol display positions or there may be a defined maximum size to the window.
The outcome evaluator 824 of game controller evaluates the selected symbols within a selected window and determines a game outcome based on the win entitlement. As indicated above, in one example, the win entitlement is based on a selected number of win lines of an available number of win lines to be used in evaluation of the game outcome, each win line extending through a plurality of symbol display positions
In one example the player can play games such as a reel power game or a 25 line game or a 3 reel game or 6 reel game in different windows. In some embodiments, the type of win entitlement may depend on window size. The game controller 60 controls the type of game that can be played by determining the size of the window based on game rules. Further in some embodiments different pay tables may apply depending on the size of the window and/or the type of win entitlement specified by the player. For example, different awards may apply to reel power games relative to win line based games.
The game controller can be programmed so as to display special features or hot spots at certain positions on the grid. For example these special features may be multipliers or wilds to provide additional excitement into the game. Another example is that a feature like a “reel shuffle” may be implemented such that symbols within a window are re-arranged if a condition is met. Such a feature may be implemented separately for each window, e.g. if windows overlap.
Game outcomes within one or more window, may provide additional game play, such as a feature game. Persons skilled in the art will appreciate that a feature game involves some additional element of game play which usually only occurs when a trigger condition is met. Types of feature games include: those where a series of free game events are awarded such as free games or re-spins (where some reels are held while others are re-spun); games where the symbols on the reel are changed; and “second screen” games where game play is totally different to the base game, for example where the player makes selections in a “pick a box type” game.
The trigger event may be, a symbol combination in the game, occurrence of a specific symbol in the game, purchased, be caused by another connected system, based on turnover, based on a random evaluation, etc.
Persons skilled in the art will appreciate that there may be more than one game round in a play of the gaming system such as is the case when a series of free spins is awarded. In this respect, a game round involves at least one of the reels being “spun”—e.g. new symbols of the reels are selected for display at the display positions and the reel is either physically or virtually spun to a stop. The outcome of a game round may be no win, a win (for example from a winning combination of symbols), a contribution towards a win accrued over a plurality of game rounds, a trigger condition occurring etc. As indicated above, a winning outcome will result in some form of award being made such as an award of credits based on the pay table 843. Such an award may never actually be physically received by a player. For example, many gaming systems provide a player with a double or nothing gamble feature, where the player can double or forfeit their credits before commencing another play of the game or cashing out. Further, as credits are fungible, once credits have been added to the credit meter it is not possible to distinguish between credits which exist because the player has input cash or the like and credits resulting from an award.
At step 903 the player can move the position of any one or more windows. The player can move the position of the windows, for example, by interacting with the touch screen of the player interface 50. In one embodiment the player can move the windows by drag and drop operations performed on the touch screen.
At step 904 the player can optionally manipulate the size of any one or more of the selected windows. In one embodiment the player can change the size of the windows by interacting with the touch screen inputting commands by gestures on the screen, for example touching one or more corners of a particular selected window and dragging the corners in a direction to increase the size of the window or reduce the size of the window or change the shape of the window. The window can be manipulated to any size or shape within limits on the size and shape of the window controlled by the game controller 60. The limits are dependent on the number of available selectable symbol display positions within the display area or on other parameters defined within the controller, e.g. a minimum or maximum window size, a maximum or minimum number of columns etc.
It should be understood a player can select multiple windows as shown in
At step 905 the player can specify the win entitlement for each window. For example the player may play a reel power game in one window and play a 25 line game in another window. The type of games that can be played within a particular selected window may depend on the size of the window. Step 906 comprises selection of one or more symbols for display at all symbol display positions by symbol selector 822.
At step 907 the method involves evaluating the symbols within a selected window determining a game outcome based on a win entitlement. The win entitlement may be different for each type of game being played, each game outcome being evaluated based on an individual win entitlement.
If an award criterion is satisfied the player is provided with an award. The player may be awarded credits or additional game play. As explained earlier the game may incorporate one or more feature games that can be triggered as a result of the play of the game. If the game controller determines that a feature should be should be awarded the feature game is carried out. If plural feature games are awarded, these may be conducted separately in different display areas on the display 54 or one after the other.
Further aspects of the method will be apparent from the above description of the system. It will be appreciated that at least part of the method will be implemented electronically, for example, digitally by a processor executing program code such as in the above description of a game controller. In this respect, in the above description certain steps are described as being carried out by a processor of a gaming system, it will be appreciated that such steps will often require a number of sub-steps to be carried out for the steps to be implemented electronically, for example due to hardware or programming limitations. For example, to carry out a step such as evaluating, determining or selecting, a processor may need to compute several values and compare those values.
As indicated above, the method may be embodied in program code. The program code could be supplied in a number of ways, for example on a tangible computer readable storage medium, such as a disc or a memory device, e.g. an EEPROM, (for example, that could replace part of memory 103) or as a data signal (for example, by transmitting it from a server). Further different parts of the program code can be executed by different devices, for example in a client server relationship. Persons skilled in the art will appreciate that program code provides a series of instructions executable by the processor.
It will be understood to persons skilled in the art of the invention that many modifications may be made without departing from the spirit and scope of the invention. In particular it will be apparent that certain features of embodiments of the invention can be employed to form further embodiments.
It is to be understood that, if any prior art is referred to herein, such reference does not constitute an admission that the prior art forms a part of the common general knowledge in the art in any country.
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.
