DETAILED DESCRIPTION

Referring to the drawings, there is shown a gaming system having a game controller arranged to implement a game wherein the same plurality of combinations of symbol positions are evaluated irrespective of the bet placed by the player. As a result, in embodiments where the game involves win lines, the same number of win lines is always evaluated irrespective of the bet.

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 comprises several core components. At the broadest level, the core components are aplayer interface50 and agame controller60 as illustrated inFIG. 1. The player interface is arranged to enable manual interaction between a player and the gaming system and for this purpose includes the input/output components required for the player to enter instructions and play the game.

Components of the player interface may vary from embodiment to embodiment but will typically include acredit mechanism52 to enable a player to input credits and receive payouts, one ormore displays54, agame play mechanism56 that enables a player to input game play instructions (e.g. to place bets), and one ormore speakers58.

Thegame controller60 is in data communication with the player interface and typically includes aprocessor62 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 amemory64 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 standalone gaming machine10 is illustrated inFIG. 2. Thegaming machine10 includes aconsole12 having adisplay14 on which are displayed representations of agame16 that can be played by a player. A mid-trim20 of thegaming machine10 houses a bank ofbuttons22 for enabling a player to interact with the gaming machine, in particular during game play. The mid-trim20 also houses acredit input mechanism24 which in this example includes acoin input chute24A and abill collector24B. Other credit input mechanisms may also be employed, for example, a card reader for reading a smart card, debit card or credit card. A player marketing module (not shown) having a reading device may also be provided for the purpose of reading a player tracking device, for example as part of a loyalty program. 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.

Atop box26 may carryartwork28, 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 afront panel29 of theconsole12. Acoin tray30 is mounted beneath thefront panel29 for dispensing cash payouts from thegaming machine10.

Thedisplay14 shown inFIG. 2 is in the form of a video display unit, particularly a cathode ray tube screen device. Alternatively, thedisplay14 may be a liquid crystal display, plasma screen, any other suitable video display unit, or the visible portion of an electromechanical device. Thetop box26 may also include a display, for example a video display unit, which may be of the same type as thedisplay14, or of a different type.

FIG. 3 shows a block diagram of operative components of a typical gaming machine which may be the same as or different to the gaming machine ofFIG. 2.

Thegaming machine100 includes agame controller101 having aprocessor102. Instructions and data to control operation of theprocessor102 are stored in amemory103, which is in data communication with theprocessor102. Typically, thegaming machine100 will include both volatile and non-volatile memory and more than one of each type of memory, with such memories being collectively represented by thememory103.

The gaming machine hashardware meters104 for purposes including ensuring regulatory compliance and monitoring player credit, an input/output (I/O)interface105 for communicating with peripheral devices of thegaming machine100. The input/output interface105 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 randomnumber generator module113 generates random numbers for use by theprocessor102. Persons skilled in the art will appreciate that the reference to random numbers includes pseudo-random numbers.

In the example shown inFIG. 3, aplayer interface120 includes peripheral devices that communicate with thegame controller101 comprise one ormore displays106, a touch screen and/orbuttons107, a card and/orticket reader108, aprinter109, a bill acceptor and/orcoin input mechanism110 and acoin output mechanism111. Additional hardware may be included as part of thegaming machine100, or hardware may be omitted as required for the specific implementation.

In addition, thegaming machine100 may include a communications interface, for example anetwork card112. 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.

FIG. 4 shows a block diagram of the main components of anexemplary memory103. Thememory103 includesRAM103A,EPROM103B and amass storage device103C. TheRAM103A typically temporarily holds program files for execution by theprocessor102 and related data. TheEPROM103B may be a boot ROM device and/or may contain some system or game related code. Themass storage device103C is typically used to store game programs, the integrity of which may be verified and/or authenticated by theprocessor102 using protected code from theEPROM103B or elsewhere.

It is also possible for the operative components of thegaming machine100 to be distributed, for example input/

output devices

106,107,108,109,110,111 to be provided remotely from thegame controller101.

FIG. 5 shows agaming system200 in accordance with an alternative embodiment. Thegaming system200 includes anetwork201, which for example may be an Ethernet network.Gaming machines202, shown arranged in threebanks203 of twogaming machines202 inFIG. 5, are connected to thenetwork201. Thegaming machines202 provide a player operable interface and may be the same as the

gaming machines

10,100 shown inFIGS. 2 and 3, or may have simplified functionality depending on the requirements for implementing game play. Whilebanks203 of two gaming machines are illustrated inFIG. 5, banks of one, three or more gaming machines are also envisaged.

One ormore displays204 may also be connected to thenetwork201. For example, thedisplays204 may be associated with one ormore banks203 of gaming machines. Thedisplays204 may be used to display representations associated with game play on thegaming machines202, and/or used to display other representations, for example promotional or informational material.

In a thick client embodiment,game server205 implements part of the game played by a player using agaming machine202 and thegaming machine202 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. Adatabase management server206 may manage storage of game programs and associated data for downloading or access by thegaming devices202 in adatabase206A. Typically, if the gaming system enables players to participate in a Jackpot game, aJackpot server207 will be provided to perform accounting functions for the Jackpot game. Aloyalty program server212 may also be provided.

In a thin client embodiment,game server205 implements most or all of the game played by a player using agaming machine202 and thegaming machine202 essentially provides only the player interface. With this embodiment, thegame server205 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 thegaming network200, including for example a gamingfloor management server208, and alicensing server209 to monitor the use of licenses relating to particular games. Anadministrator terminal210 is provided to allow an administrator to run thenetwork201 and the devices connected to the network.

Thegaming system200 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 afirewall211.

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, thegame server205 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 toFIG. 6, the player operatesgame play mechanism56 to input an initiate play instruction selected from one of a plurality of available initiate play instructions. As described above, the game play mechanism can be in the form of a touch screen and/or buttons. In the embodiment, irrespective of the initiate play instruction that is entered theoutcome evaluator623 evaluates the same plurality of combinations of display positions in accordance with at least onegame rule642.

In one embodiment, theoutcome evaluator623 will evaluate a plurality of win lines specified bygame rule data641.FIG. 8 shows an example of agame play mechanism56 for such an embodiment. In this example, there are 25 win lines evaluated. A player can choose between four different initiate play instructions by pressing (or touching in a touch screen embodiment) one of

buttons

561,562,563,564.Button561 corresponds to a bet of 25 credits,button562 corresponds to a bet of 50 credits andbutton563 corresponds to a bet of 250 credits. “Play Again”button564 may be employed to initiate play using the previously placed bet again.

Theoutcome generator622 operates in response to the player's operation ofgame play mechanism56 to generate a game outcome which will then be evaluated byoutcome evaluator623. The outcome generator forms the game outcome by employingrandom number generator621 to randomly select symbols from a set of symbols specified bysymbol data641. The selected symbols are advised to thedisplay controller625 which causes them to be displayed ondisplay54 at a set of display positions.Outcome generator622 selects symbols for display from a plurality of symbol sets corresponding to respective ones of a plurality of spinning reels. Thus, the symbol sets641 specify a sequence of symbols for each reel such that theoutcome generator622 can, in one example, select symbols for display by selecting a stopping position in the sequence. In one example, three symbols of each of five reels may be displayed such that symbols are displayed at fifteen display positions ondisplay54. To obtain a desired return to player, a probability table having weighted outcomes is typically employed when selecting the symbols.

Outcome evaluator

623 evaluates each of the plurality of win lines to determine which, if any, of the win lines corresponds to a winning combination specified in theprize data642A based on game rules. For example, the game rules may specify that all combinations are evaluated left to right or can be evaluated right to left or both. Depending on the specific rules of the game implemented by the embodiment, the outcome evaluator may evaluate the win lines to determine whether they provide a trigger for a feature (or secondary) game.

Theoutcome evaluator623 may also make additional evaluations known in the art, for example “scatters” where a player is awarded a prize or a feature game for a designated number of symbols, irrespective of whether they are on a win line. By way of example, the feature game may be a series of free games, in whichcase outcome evaluator623 triggersoutcome generator622 to carry out a series of free games andoutcome evaluator623 evaluates each of these games to determine any awards to be made.Prize awarder624 determines the quantum of the award to be made from the initiate play instruction (e.g. based on the size of the bet) and the prizes are accumulated to a win meter stored asmeter data643. Once all outcomes have been generated and a further game play instruction is required before any further play can occur, credits are transferred to a credit meter inmeter data643. In embodiments, where a gamble feature is offered it may be possible, for example to seek to double the accumulated win at the risk of losing it. In such embodiments, it may be necessary for a player to operate thegame play mechanism56 to indicate they want to take an accumulated win or to initiate a further play of the game before credits are transferred from the win meter to the credit meter.

Persons skilled in the art will appreciate that win lines are formed by a combination of displayed symbol positions, one from each reel, the symbol positions being located relative to one another such that they form a line. Examples of win lines are given in Australian patent 684195 owned by Aristocrat Technologies Australia Pty. Ltd.

FIG. 6 shows anoperator interface66 which is deployed in some embodiments to enable the operator of the venue at which the game can be played to configure the number of lines which constitute the plurality of win lines. In this example, the operator can select between 4 options,661,662,663,664 corresponding to different numbers of a plurality of win lines offerable under the game rules642. For example, 6, 9, 15 or a maximum of 25 lines. In such embodiments, the game rules641 may default to the maximum number of lines offerable under the game rules. In such embodiments, it may be desirable for the game play mechanism to be provided by touch screen buttons to make it easy to change the text displayed to each player on the buttons.

In the above description it will be appreciated that the various of the above functional modules are implemented byprocessor62 executing code stored inmemory64. Persons skilled in the art will appreciate that other embodiments are possible including dedicated circuits.

Persons skilled in the art, will appreciate that in other embodiments, the outcome evaluator may evaluate symbol combinations in a different way. For example, in the manner in which outcomes are evaluated in games marketed under the trade name “Reel Power” by Aristocrat Leisure Industries Pty Ltd and described in U.S. Pat. No. 6,093,102. In such games symbol combinations are made by forming combinations from each selected reel by combining it with all the selected positions of other reels. In other words, all symbol positions of a selected reel can be used to form symbol combinations with designated, symbol display positions of other reels. This means that in embodiments where there are three symbols displayed for each reel and five reels, there are 243 different symbol combinations (35) to be evaluated by the outcome evaluator (also known as “ways” to win). Thus in this embodiment, the game rules641 may specify for example the evaluation of 2, 3, 4 or 5 reels irrespective of the game play instruction. This may be configurable by the operator in the manner described above.

Themethod700 is summarised inFIG. 7 and involves receiving710 an initiate game play instruction, generating720 a game outcome, and evaluating730 plural different combination of symbol positions irrespective of the initiate play instruction.

Persons skilled in the art will also appreciate that the method of the embodiment could be embodied in program code. The program code could be supplied in a number of ways, for example on a computer readable medium, such as a disc or a memory (for example, that could replace part of memory103) or as a data signal (for example, by downloading it from a server which results in the program code being transmitted from the server to a gaming machine or computer which receives it).

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.

It is to be understood that, if any prior art publication is referred to herein, such reference does not constitute an admission that the publication forms a part of the common general knowledge in the art, in Australia or any other 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.
