In order that the present invention may be more clearly ascertained, embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings, in which:
The present gaming system operates such that during game play, a plurality of symbols are randomly selected from a set of symbols and displayed in a corresponding plurality of display position groups, each of which comprises a plurality of display positions. The symbols shown at the display positions are used to determine game outcomes by comparing the displayed symbols with defined winning combinations.
In one conventional type of gaming machine, a display area including 15 display positions is presented to a player with each display position including one symbol. The display positions are arranged in five vertically disposed display position groups, with each display position group corresponding to a rotatable reel, and each reel having three visible display positions. After the reels are spun and subsequently stopped, the display positions show a random selection of symbols.
Generally, with such games, a plurality of win patterns in the form of win lines are defined which extend across the reels and include one display position from each reel. Typically the symbols that are disposed in a win line are compared with winning symbol combinations defined in a pay table so as to determine whether a player of the game should receive an award. For example, if winning symbol combinations are based on poker hands, a particular prize would be awarded if the win line comprises four aces. Other winning symbol combinations and corresponding prizes may also be defined.
Such a game often comprises normal game mode and special game mode. During normal game mode, the displayed symbols are compared with winning combinations defined in a pay table.
With the present system, during special game mode, the gaming system is arranged to select symbols in a first set of display position groups, and provide the player with the option of keeping the selected symbols or re-selecting symbols for display in the first set of display position groups before symbols are selected for display in a remaining second set of display position groups. In this way, interactivity between the gaming system and a player is increased, and the player has a degree of control over the game in a way similar to draw poker whereby the player has the option of keeping or replacing the symbols initially displayed. While the present embodiment is described in relation to implementation of this functionality during special game mode, it will be understood that the functionality may be implemented during normal game mode of a multi-mode gaming system, or in a gaming system that has only a single mode of operation.
Referring to the drawings, there is shown a schematic block diagram of a gaming system 10 arranged to implement a probabilistic game of the type wherein several symbols from a set of symbols are randomly displayed, and a game outcome is determined on the basis of the displayed symbols. The system is of the type including multiple game modes, such as being operable in normal game mode wherein a base game is implemented and special game mode wherein a feature game is implemented.
With some such probabilistic games, the set of symbols used during normal game mode include standard symbols and function symbols, and the game outcome is determined on the basis of the displayed standard symbols and the function associated with any displayed function symbol. 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 along a win line, or are displayed according to defined outcome patterns such as scattered, and so on. The function associated with a function symbol may be for example a wild function wherein display of the function symbol is treated during consideration of the game outcome as any of the standard symbols. A function symbol may be represented as the word “WILD”, a star, or by any other suitable word or symbol. Other functions are also envisaged such as scatter functions, multiplier functions, repeat win functions, jackpot functions and feature commencement functions.
Referring to
Components of the player interface 30 may vary but will typically include a credit mechanism 34 to enable a player to input credits and receive payouts, one or more displays 36 which may comprise a touch screen, and a game play mechanism 38 arranged to enable a player to input game play instructions.
The game controller 32 is in data communication with the player interface 30 and typically includes a processor 40 arranged to process game play instructions and output game player outcomes to the display 36. Typically, the game play instructions are stored as program code in a memory 42 that can also be hardwired. It will be understood that in this specification the term “processor” is used to refer generically to any device that can process game play instructions and may include a microprocessor, microcontroller, programmable logic device or other computational device such as a personal computer or a server.
A functional diagram illustrating operative components of the game controller 32 is shown in
The memory 42 is arranged to store symbols data 14 indicative of a plurality of symbols, in the present example associated with a plurality of reels, win lines data 16 indicative of available win lines, and game instruction data 18 indicative of game instructions usable by the gaming machine 10 to control operation of the game.
The game controller 32 includes a symbol selector 20 which is arranged to select several symbols from the available symbols 14 for display to a player in a plurality of display positions, in this example by spinning reels containing the symbols and stopping the reels so as to display at least one symbol on each reel. In this example, the selection carried out by the symbol selector 20 is made using a random number generator 22.
It will be appreciated that the random number generator 22 may be of a type which is arranged to generate pseudo random numbers based on a seed number, and that in this specification the term “random” will be understood accordingly to mean truly random or pseudo random.
The symbol selector 20 interfaces with a reel controller 26 arranged to control and coordinate the reels, and in particular to control the stopping positions of the reels.
With this embodiment, the game controller 32 also comprises a trigger determiner 23 arranged to determine whether a trigger condition exists, and a feature implementer 25 arranged to implement a feature game when a trigger condition is determined to exist.
During a feature game, the feature implementer 25 causes the symbol selector 20 to select symbols for display from a first set of symbol display groups, in this example symbols from some but not all of the reels, and causes the reel controller 26 to spin all of the reels and subsequently stop some but not all of the reels in order to thereby display the symbols selected in the first set of symbol display groups. No symbols are displayed at this stage in a second set of symbol groups, in this example the remaining reels, and these reels continue to spin. The player is then provided with the option of keeping the symbols selected for display in the first set of symbol display groups or re-selecting the symbols for display in the first set of symbol display groups and thereby re-spinning the reels associated with the first set of symbol display groups. Player selection may be made using a touch screen 27, using buttons, or in any other way
The game controller 32 also comprises an outcome evaluator 28 which, in accordance with game instructions 18, determines game outcomes based on the symbols selected for display to the player by the symbol selector 20 after all reels have stopped spinning.
The game controller 32 also comprises a prize allocator 29 arranged to allocate a prize to a player when a winning outcome exists.
In the present embodiment, the symbol selector 20, the trigger determiner 23, the function allocator 24, the feature implementer 25, the reel controller 26, the outcome evaluator 28, and the prize allocator 29 are at least partly implemented using the processor 40 and associated software although it will be understood that other implementations are envisaged.
The gaming system 10 can take a number of different forms.
In a first form, a player operable gaming device in the form of a stand alone gaming machine is provided wherein all or most components required for implementing the game are present in the 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 device and some of the components required for implementing the game are located remotely relative to the gaming device. For example, a “thick client” architecture may be used wherein part of the game is executed on a player operable gaming terminal 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 terminal 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 device is networked to a device 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.
A gaming system in the form of a stand alone gaming machine 50 is illustrated in
A top box 66 may carry artwork 68, 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 69 of the console 52. A coin tray 70 is mounted beneath the front panel 69 for dispensing cash payouts from the gaming machine 50.
The display 54 is in the form of a video display unit, particularly a cathode ray tube screen device. Alternatively, the display 54 may be a liquid crystal display, plasma screen, or any other suitable video display unit. The top box 66 may also include a display, for example a video display unit, which may be of the same type as the display 54, or of a different type. The display 54 may comprise a touch screen usable by a player to interact with the gaming machine, in particular during game play.
The display 54 in this example is arranged to display representations of several reels, each reel of which has several associated symbols. Typically 3, 4 or 5 reels are provided. During operation of the game, the reels first appear to rotate then stop with typically three symbols visible on each reel. Game outcomes are determined on the basis of the visible symbols together with any special functions associated with the symbols.
A player marketing module (PMM) 72 having a display 74 is connected to the gaming machine 50. The main purpose of the PMM 72 is to allow the player to interact with a player loyalty system. The PMM has a magnetic card reader for the purpose of reading a player tracking device, for example as part of a loyalty program. However other reading devices may be employed and 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. In this example, the PMM 62 is a Sentinel III device produced by Aristocrat Technologies Pty Ltd.
The gaming machine 100 includes a game controller 101 having a processor 102. Instructions and data to control operation of the processor 102 in accordance with the present invention 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 a player interface 120 of the gaming machine 100, the player interface 120 having several peripheral devices.

A random number generator module 113 generates random numbers for use by the processor 102.
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 may 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, a 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 205 and the gaming machine 202 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.
In a variation of the above thick client embodiment, the gaming machine 202 may implement the game, with the game server 205 functioning merely to serve data indicative of a game to the gaming machine 202 for implementation.
With this implementation, a data signal containing a computer program usable by the client terminal to implement the gaming system may be transferred from the game server to the client terminal, for example in response to a request by the client terminal.
In a thin client embodiment, the 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, and pass the instructions 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 system 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 monitor the network 201 and the devices connected to the network.
The gaming system 200 may communicate with other gaming systems, other local networks such as a corporate network, and/or a wide area network such as the Internet, for example through a firewall 211.
A loyalty program server 212 may also be provided.
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.
Examples of specific implementations of the gaming system will now be described in relation to a stand alone gaming machine 50 although it will be understood that implementation may also be carried out using other gaming system architectures such as a network architecture of the type shown in
In this example, the gaming system comprises five reels, each reel corresponding to a display position group having an associated set of display positions for displaying symbols. The reels may be mechanical or virtual.
The reels are arranged to display standard symbols and one or more function symbols and win outcomes are determined on the basis of the symbols visible at the display positions when the reels stop.
Typically, a player will purchase or otherwise obtain win entitlements such as several win lines which are used in the game to determine win outcomes. If the displayed symbols on the reels have symbols associated with a winning combination such as a winning combination disposed on a win line, the player wins a prize.
The gaming system is operable in normal game mode and special game mode and may be arranged to commence special game mode when a predetermined game outcome occurs. Special game mode may comprise one or more free games. Special game mode may commence automatically on the basis of a game event occurring during a game such as display of a particular symbol, based on game outcomes determined by the gaming system, or may be prompted by a player pressing a button on the gaming system 10 after the player has identified that a game outcome corresponding to special game mode requirements has occurred.
The gaming system 10 may also be arranged so as to determine eligibility for special game mode, for example based on the amount or type of bet placed, based on particular time periods and so on.
Special game mode may also be arranged to commence when a special game is purchased by a player.
A specific example will now be described in relation to flow diagram 250 shown in
As shown in
During implementation 254 of a base game, the reels are spun and subsequently stopped to show a plurality of symbols 294 in the display area 290. Winning outcomes are determined with reference to symbols 294 appearing in the display area 290, for example along defined win lines.
The outcome generator 28 determines whether the symbols displayed at the display positions correspond to a winning outcome and, if a winning outcome exists, a prize associated with the winning outcome is awarded 256 to the player. This determination is made by comparing the symbols displayed at the display positions with a pay table or similar.
If a predefined game outcome occurs 258 during the base game, such as display of a defined combination of symbols, the gaming system implements a feature game.
During implementation of the feature game, the reels are caused to spin and some of the reels are stopped 260 so as to thereby select the symbols to be displayed on the reels in the display area, as shown in
As indicated at step 262 of the flow diagram 250 and shown in
If the player chooses to keep the symbols displayed on the first, second and third reels 280, 282, 284, symbols for display on the fourth and fifth reels 286, 288 are selected, the virtual shutters 302 open and the fourth and fifth reels 286, 288 are caused to stop 268 so as to display the selected symbols, as shown in
If the player does not choose to keep the symbols displayed on the first, second and third reels 280, 282, 284, symbols for display on all reels are re-selected, all five reels 280, 282, 284, 286, 288 are re-spun, as shown in
It will be appreciated that in some embodiments the shutters may be omitted such that all reels are always visible during implementation of the feature game.
It will also be appreciated that the above feature game implementation described in relation to
It will also be appreciated that instead of stopping the first three reels and providing a player with the option of keeping the symbols shown on the stopped reels, any one or more of the reels may be stopped and the player provided with this option, such as the first reel only, the first and third reels only, and so on. As a further variation, the stopped reels may be selected randomly.
While the above embodiment is described in relation to a gaming system wherein virtual reels are displayed on a graphical display device, it will be understood that, as an alternative, physical reels may be provided instead of virtual reels. With this embodiment, physical shutters may be provided to selectively conceal one or more of the reels.
