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 at least during a portion of a game implemented by the gaming system, a display area is provided including a plurality of display positions. The display positions define a plurality of win lines, some of which have differing numbers of display positions or game matrix coordinates. In this way, win lines comprising differing numbers of display positions/coordinates/symbols are provided which allows different win possibilities to be provided according to the number of display positions in the win lines.
In some embodiments, win lines with differing numbers of display positions are achieved by arranging the display positions so that the display positions together define a generally diamond shaped display area (game matrix), and defining win lines which traverse the display area left to right, right to left or both ways. In other embodiments, the display positions may define a generally square or rectangular shaped display area and win lines defined which extend generally diagonally across the display area.
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 may have a single mode of operation or may be of the type including multiple game modes, such as 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 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, function data 16 indicative of one or more functions allocatable to the symbols, 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 15 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.
With this embodiment, the game controller 32 also comprises a trigger determiner 24 arranged to determine whether a trigger condition exists, and a feature implementer 25 arranged to cause the gaming system to operate in special mode wherein a feature game is implemented when a trigger condition exists. Such a trigger condition may be display of a particular symbol or combination of symbols corresponding to a winning combination and the selected identifier 15 in this example is applied to the prize associated with the winning combination so as to increase or decrease the prize, or maintain the prize the same.
The gaming system may also be arranged so as to operate in normal game mode wherein at least one base game is implemented and special game mode wherein at least one feature game is implemented. The trigger determiner 24 may be arranged so as to commence special game mode based on display of a particular symbol or combination of symbols during normal game mode.
In this example, the game controller 32 also comprises a function allocator 27 arranged to select and allocate one or more functions to one or more symbols. Such functions include a wild function, a scatter function, or any other function which may be applied to a symbol or to the game.
The game controller 32 also comprises an outcome evaluator 28 which in accordance with the game instructions 18 determines game outcomes based on the symbols selected for display to the player by the symbol selector 20, and a prize allocator 29 arranged to allocate a prize to a player when a winning outcome exists.
In the embodiments described below, the symbol selector 20, the trigger determiner 24, the feature implementer 25, the function allocator 27, and 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. 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 device in the form of a gaming terminal 202 and the gaming terminal 202 essentially provides only the player interface. With this embodiment, the game server 205 provides the game controller. The gaming terminal will receive player instructions, and pass the instructions to the game server which will process them and return game play outcomes to the gaming device for display. In a thin client embodiment, the gaming devices 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 10 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 is operable in normal game mode and special game mode and the gaming system comprises five reels, each of which has an associated set of symbols.
The reels comprise standard symbols and optionally 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 rotating.
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 disposed on a win line, the player wins a prize.
The gaming system may be arranged to commence special game mode when a predetermined game outcome occurs, and special game mode may comprise one or more feature 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 after the player has identified that a game outcome corresponding to special game mode requirements has occurred.
The gaming system 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 certain time periods and so on.
Special game mode may also be arranged to commence when a special game is purchased by a player.
The system and method may also be configured to provide for “scatter” wins for symbols appearing anywhere in the game display matrix.
A specific example will now be described in relation to flow diagram 250 shown in
An example display area 300 of an embodiment of the invention is shown in
It will be understood that since some win lines have different numbers of display positions, the winning outcomes available will be different for the win lines having 3, 4 or 5 display positions.
Since the win possibilities are different for win lines including 3, 4 or 5 symbols, the gaming system may be arranged such that for example the third win line 320 which comprises 3 display positions is cheaper for a player to purchase than the first win line 316 which comprises 5 display positions. This reflects the greater potential prize that a player could achieve with a 5 display position win line than with a 3 display position win line. Alternatively the award schedule for the second and third win lines 318, 320 may be different because of the diminished number of included display positions. Thus, in one configuration, the award schedule may be configured to offer different awards based upon the number of display positions associated therewith.
In the present example, a winning outcome including 4 ACE symbols (2 WILD (W) symbols and 2 ACE (A) symbols) occurs on the first line 316 and, accordingly, a prize associated with a win comprising 4 symbols on the first line 316 is awarded to the player. The player may also be awarded for 3 Queen (Q) symbols on the second win line 318.
A further example winning outcome is shown in
An example display area 400 of a further embodiment of the invention is shown in
In the present example, a winning outcome including 5 QUEEN symbols (1 WILD symbol and 4 QUEEN symbols) occurs on a win line 420 and, accordingly, a prize associated with a win comprising 5 QUEEN symbols on the win line 420 is awarded to the player.
A further example display area 500 of an embodiment of the invention is shown in
As with the above described embodiments, since some win lines have different numbers of display positions, the winning outcomes available will be different for the win lines having 3, 4 or 5 display positions.
In the present example, no winning outcome exists.
The above embodiments described in relation to
The gaming system in this example is arranged to operate in normal game mode and special game mode. Special game mode commences when a trigger condition exists and during special game mode at least one feature game is implemented.
The gaming system may be arranged so that a game with multiple win lines, at least some of which have differing numbers of display positions, is implemented during both normal game mode and special game mode or only as part of a feature game during special game mode.
In an alternative arrangement, the gaming system is arranged to operate in normal game mode only. In an alternative embodiment a traditional three reel of five reel base game may be offered with the diamond shaped reels of
It will be appreciated that while the above embodiments are described in relation to a display area of generally diamond or square configuration, it will be understood that many variations are possible to the extent that any shape display area may be provided, the important aspect being that win lines having differing numbers of display positions are defined.
In the claims of this application and in the description of the invention, except where the context requires otherwise due to express language or necessary implication, the words “comprise” or variations such as “comprises” or “comprising” are 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.
