In accordance with a third aspect of the present invention, there is provided a computer readable data storage device having a computer readable program code embodied therein for causing a computer to operate in accordance with the gaming system of the first aspect.
The present invention will now be described, by way of example only, with reference to the accompanying drawings, in which:
a to 8c are diagrammatic representations of a display area of a gaming system in accordance with an embodiment of the present invention shown during implementation of a game.
The present gaming system implements a probabilistic type game wherein a plurality of symbols are selected and displayed in a plurality of display position groups. During the game, or during implementation of a feature game, at least one of the display position groups is selected and obscured or the otherwise made less visible than the other display position groups. A first game outcome is determined on the basis of symbols displayed when one or more of the display position groups is obscured or otherwise made less visible. At least one of the obscured/less visible display position groups is then revealed or otherwise made as visible as the other display position groups, and a second game outcome is determined on the basis of the symbols displayed.
In this way, at least 2 game outcomes are determined, one when at least one symbol group obscured or otherwise made less visible, and the other when the at least one symbol group is revealed or otherwise made as visible as the other display position groups.
In one embodiment, a mechanical shutter is disposed over each of the reels, and each shutter is controllable so as to selectively move between a closed position wherein the shutter obscures a respective reel or an open position wherein the shutter does not obscure the respective reel and the reel is revealed.
In an alternative embodiment, at least one virtual shutter device is disposed over the reels, the virtual shutter device being controllable in response to an electronic signal so as to be disposable, at selected parts of the device, in a substantially transparent state wherein one or more reels are visible through the device or a substantially opaque state wherein one or more reels are not visible through the device.
In a further alternative embodiment, instead of providing a mechanical or virtual shutter to obscure one or more of the reels, the gaming system may be arranged to modify the lighting at one of more reels so that the symbols on one or more of the reel(s) are noticeably less visible than symbols on the other reels.
In one conventional type of gaming machine, a spinning reel type game comprises a display area including 15 display positions, with each display position including one symbol. The display positions are arranged in five vertically disposed reels, with each reel corresponding to a display position group, 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.
Referring to
The components comprise a player interface 30 and a game controller 32. The player interface 30 is arranged to enable interaction between a player and the gaming system and for this purpose includes input/output components required for the player to enter instructions and play the game.
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.
With the present embodiment, a mechanical spinning reel type game is implemented during normal game mode. The set of symbols used 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.
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 selectable symbols, win outcome data 16 indicative of win condition requirements games implemented by the system, and game instruction data 18 indicative of game instructions usable by the gaming machine 10 to control operation of the games.
The game controller 32 includes a symbol selector 20 which is arranged during normal game mode to select several symbols for display to a player in a plurality of display positions on a plurality of reels, and a reel controller 21 arranged to control spinning and stopping of the reels so that the reels stop with the selected symbols displayed. 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.
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.
For use during the feature game, the gaming system 10 also includes a shutter 27 for each of the reels, and a shutter controller 26 arranged to control the shutters in order to selectively dispose each of the shutters in an open configuration or a closed configuration.
In this example, the shutters 27 are mechanical shutters selectively individually movable between a first position wherein the shutter conceals a reel and a second position wherein the shutter does not conceal the reel.
However, it will be understood that other arrangements are possible. For example one or more virtual shutters may be provided, each virtual shutter being electronically controllable so as to dispose the shutter or part of the shutter in a substantially transparent or substantially opaque state.
During a feature game, the feature implementer 25 instructs the shutter controller 26 to close one or more of the shutters 27 so that at least one selected reel is concealed and is therefore not visible to a player.
The reel that is concealed may be selected by the gaming system, for example randomly using the random number generator 22 or based on a defined process, or may be selected by a player using a reel selector 31. The reel selector 31 may comprise a touch screen or one or more buttons.
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 during normal game mode when all reels are visible, and during special game mode when at least one selected reel is obscured by a shutter or otherwise made less visible and when the at least one selected reel is not obscured by a shutter.
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 21, the shutter 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 top box 66 may also include a display, for example a video display unit, which may be of the same type as the video display unit, or of a different type.
Typically, 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. 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.
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
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
In this example, the gaming system comprises 5 reels 280
arranged to display standard symbols and one or more function symbols during implementation of a base game. 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.
During normal game mode, all 5 reels 280 are visible. The reels spin and are subsequently controlled by the reel controller 21 to stop such that selected symbols are displayed. The displayed symbols are then evaluated by the outcome evaluator 28 and if the displayed symbols correspond to a winning outcome, a prize is awarded by the prize allocator 29.
If a trigger condition exists, for example if one or more defined symbols are displayed, the trigger determiner 23 identifies the trigger condition and instigates special game mode wherein at least one feature game is implemented.
As shown in
After the selected reel is obscured by the shutter 282, the 5 reels spin and are subsequently controlled by the reel controller 21 to stop such that selected symbols 284 in 4 of the reels are visible and selected symbols on one of the reels are obscured from view by the shutter 282, as shown in
In the example shown in
As shown in
In the example shown in
As an alternative, instead of obscuring one reel with a shutter, the gaming system may be arranged to obscure more than one reel, with each reel being selected by a player or selected randomly by the gaming system. With this implementation, the selected reels may be obscured and revealed at the same time, or the reels may be obscured together, each reel revealed individually and a game outcome evaluated after each reel is revealed.
With this alternative embodiment, each previously concealed reel that is to be revealed may be selected by a player or randomly by the gaming system, for example such that the order of reels that are revealed is determined by the player or randomly by the gaming system.
For implementations that are arranged to obscure more than one reel, subsequent reels may be revealed in response to a game condition, such as a random trigger or display of a particular symbol or combination of symbols.
As a further alternative, instead of obscuring one or more reel, the or each selected reel may be made less visible than the reels that have not been selected. This may be achieved by modifying lighting associated with the gaming system such that selected reels are not illuminated or illuminated less than reels that have not been selected.
While the present embodiment is described in relation to a mechanical type base game, it will be understood that other arrangements are envisaged. For example, the reels may be virtual reels shown on a display device.
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.
Modifications and variations as would be apparent to a skilled addressee are determined to be within the scope of the present invention.
