AUSTRALIA Patents Act 1990 COMPLETE SPECIFICATION STANDARD PATENT Applicant: Aristocrat Technologies Australia Pty Limited Invention Title: A Gaming System And A Method Of Gaming -2 A GAMING SYSTEM AND METHOD OF GAMING Field of the Invention 5 The present invention relates to a gaming system, a controller, and method for awarding prizes. Background of the Invention 10 Many venues employ controllers for awarding prizes to one or more of a plurality of gaming devices participating in a linked event. For example, in a linked event where jackpot prizes are awarded, a portion of turnover on each gaming device will typically be forwarded to a jackpot controller as 15 a contribution. That is, part of each wager goes towards the jackpot. The technique can be extended to a so called wide area jackpot where gaming devices from a number of different venues contribute to a single jackpot pool. 20 One common way of awarding a jackpot is a so called mystery jackpot where a trigger value, generally in a prize range, is randomly selected and stored by the jackpot controller. The jackpot controller determines to award the jackpot prize when the contributions cause the value of the jackpot pool to 25 reach the trigger value. While such techniques provide an opportunity for players to win large jackpot prizes, the need exists for alternative gaming systems in order to maintain or increase player 30 enjoyment. It would also be advantageous if there was provided a gaming system for increasing the social interaction between players.

The jackpot controller comprises a jackpot determination module which is arranged to award a primary prize to a first gaming device 15 participating in the gaming event, and determine at least one second gaming machine to award a secondary prize. The determination is based at least in part on the location of the second gaming device with respect to the first gaming device. An award module is also provided to award the 20 primary prize and secondary prize. General System Configuration In the gaming system configuration 100, a jackpot controller 25 110 is in data communication with a plurality of gaming devices 120 over a network 130. The gaming devices 120 are arranged in two banks 103 of two gaming machines 120. A person skilled in the art will also appreciate that other configurations may be viable.

-8 Gaming Devices Herein, the term gaming device is used to refer to any device used by a player to a play a game and specifically includes 5 stand alone gaming machines and interactive video terminals which implement games in a client/server architecture. A gaming device in the form of a stand alone gaming machine 10 is illustrated in Figure 2. The gaming machine 10 includes 10 a console 12 having a display 14 on which is displayed representations of a game 16 that can be played by a player. A mid-trim 20 of the gaming machine 10 houses a bank of buttons 22 for enabling a player to interact with the gaming machine, in particular during game play. The mid-trim 20 15 also houses a credit input mechanism 24 which in this example includes a coin input chute 24A and a bill collector 24B. 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 comprising a 20 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. 25 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 30 console 12. A coin tray 30 is mounted beneath the front panel 29 for dispensing cash payouts from the gaming machine 10.

-9 The display 14 shown in Figure 2 is in the form of a video display unit, particularly a cathode ray tube screen device. Alternatively, the display 14 may be a liquid crystal display, plasma screen, any other suitable video display 5 unit, or the visible portion of an electromechanical device. The top box 26 may also include a display, for example a video display unit, which may be of the same type as the display 14, or of a different type. 10 Figure 3 shows a block diagram of operative components of a typical gaming machine 300 which may be the same as or different to the gaming machine of Figure 2. The gaming machine 300 includes a game controller 301 having 15 a processor 302. Instructions and data to control operation of the processor 302 are stored in a memory 303, which is in data communication with the processor 302. Typically, the gaming machine 300 will include both volatile and non volatile memory and more than one of each type of memory, 20 with such memories being collectively represented by the memory 303. The gaming machine has hardware meters 304 for purposes including ensuring regulatory compliance and monitoring 25 player credit, an input/output (I/0) interface 305 for communicating with peripheral devices of the gaming machine 300. The input/output interface 305 and/or the peripheral devices may be intelligent devices with their own memory for storing associated instructions and data for use with the 30 input/output interface or the peripheral devices. A random number generator module 313 generates random numbers for use by the processor 302. Persons skilled in the art will - 10 appreciate that the reference to random numbers includes pseudo-random numbers. In the example shown in Figure 3, a player interface 320 5 includes peripheral devices that communicate with the game controller 301 comprise one or more displays 306, buttons and/or a touch screen 307, a card and/or ticket reader 308, a printer 309, a bill acceptor and/or coin input mechanism 310 and a coin output mechanism 311. Additional hardware may be 10 included as part of the gaming machine 300, or hardware may be omitted as required for the specific implementation. In addition, the gaming machine 300 may include a communications interface, for example a network card 312. 15 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. 20 Figure 4 shows a block diagram of the main components of an exemplary memory 303. The memory 303 includes RAM 303A, EPROM 303B and a mass storage device 303C. The RAM 303A typically temporarily holds program files for execution by the processor 302 and related data. The EPROM 303B may be a 25 boot ROM device and/or may contain some system or game related code. The mass storage device 303C is typically used to store game programs, the integrity of which may be verified and/or authenticated by the processor 302 using protected code from the EPROM 303B or elsewhere.

- 11 It is also possible for the operative components of the gaming machine 300 to be distributed, for example input/output devices 306,307,308,309,310,311 to be provided remotely from the game controller 301. 5 A gaming device as indicated above may also take the form of a client/server architecture where a portion of the game is executed on the client and a portion of the game is executed on the server. In such embodiments, the client typically 10 takes the form of an interactive video terminal which has a similar outward appearance to the gaming machine described above. A person skilled in the art will appreciate that the type of gaming device that is employed is not important to the present invention. 15 Further Detail of the Controller As described in preceding paragraphs, embodiments of the present invention relate to systems and methods for awarding 20 primary and secondary prizes to gaming devices participating in a linked gaming event, such as a linked event implemented over the network 130 (described previously with reference to Figure 1). 25 More particularly, the system may determine non primary prize-winning gaming devices (hereafter "second gaming devices") to award the secondary prize, with the determination based, in part, on the location of the second gaming device with respect to the primary prize winning 30 device (hereafter "first gaming device"). For example, secondary prizes may be awarded to second gaming devices located within a specified distance of, or number of devices adjacent to the first gaming device. In accordance with such - 12 an embodiment, the sense of community shared between the players may be heightened. To carry out such functionality, the gaming system 100 5 comprises a controller as shown in more detail in Figure 5. According to the described embodiment, the controller is in the form of a jackpot controller 110 which can be incorporated, for example, into a jackpot server of the gaming system 100. For simplicity, only those modules needed 10 to carry out embodiments of the invention are illustrated in Figure 5. The jackpot controller 110 includes a processor 52 which is arranged to carry out the functions associated with awarding 15 the primary prize and secondary prize in the linked gaming event. It will be apparent that the processor 52 implements a number of modules, namely a random number generator 521, determination module 522, award module 524 and display controller module 526, based on program code stored in memory 20 54. The memory 54 is also arranged to store a database 528 providing the necessary information to determine the relative position/orientation of each gaming device participating in 25 the linked gaming event. In one embodiment, each gaming device is referenced by a unique number which is used in all communications to/from the linked gaming device. Upon set up, a positional map is built by the jackpot controller 110 which includes the identifier of each participating gaming 30 device, the relevant bank number and associated position therein.

- 13 For example, with reference to the example implementation shown in Figure 6, the following data may be stored in the database 528 for gaming devices 120a to 120g: No Identifier Bank Position 120a 2000021 103b 4 120b 2000022 103b 3 120c 2000026 103b 5 120d 2000024 103b 2 120e 2000027 103b 6 120f 2000023 103b 1 120g 2000028 103b 7 120h 2000029 103a 4 5 Table 1: Map Data The map is manually entered into the database 528. However, in alternative embodiments the map could be automatically built by the jackpot controller 110 using the relevant data 10 communicated from the respective gaming devices 120a to 120g during initialisation. The linked gaming event implemented by the gaming system 200 is in the form of a progressive mystery-type jackpot game, 15 with the primary prize corresponding to the major primary prize awarded in the jackpot game. Persons skilled in the art will appreciate that the linked gaming event could comprise of any conventional linked gaming event, including, for example, outcome-based jackpot systems and the like. 20 With reference to Figure 6, there is shown an example implementation for awarding prizes in a progressive mystery type jackpot game. In such an example implementation, gaming - 14 devices 120 are located in a series of banks 103a, 103b, 103c. A percentage of each wager placed by the gaming devices 120 in a base game, such as a standard reel game, goes towards a progressive jackpot prize pool. A jackpot 5 trigger value is predetermined by the jackpot controller 110 to fall between a lower jackpot value and upper jackpot value. The jackpot trigger value falls somewhere between the lower and upper jackpot value and is randomly determined utilising the RNG 521. Upon reaching or surpassing the 10 jackpot trigger value, a jackpot event is initiated by the jackpot controller 110. The jackpot determination module 522 subsequently determines which of the linked gaming devices 120 provided the contribution that triggered the jackpot event and awards that device with the primary prize (i.e., in 15 this embodiment, the jackpot prize). In the illustrated embodiment, gaming device 120a triggered the jackpot event and is therefore awarded the jackpot prize. Responsive to determining that the jackpot prize is to be 20 awarded, the determination module 522 determines at least one second gaming device to award a secondary prize. The determination is based, in part, on the location of the second gaming device with respect to the gaming device that is to be awarded the jackpot prize, i.e. gaming device 120a. 25 According to the embodiment described herein, in order to be awarded a secondary prize, the second gaming devices must be located within a specified number of gaming devices adjacent gaming device 120a. For example, in Figure 6, only linked devices located within two adjacent positions of the first 30 gaming device 120a are to be awarded the secondary prize. The secondary prize may, for example, take the form of bonus credits, coupons, feature games or any other conventional prize suitable for awarding to a gaming device. In the - 15 illustrated embodiment, however, a proportional amount of the total jackpot prize is awarded to the second gaming devices, which decreases in value the further away the devices are located from the first gaming device 120a. 5 For example, in Figure 6, gaming devices 120b and 120c are both located immediately adjacent the first gaming device 120a (i.e. at positions 3 and 5) and are therefore awarded a higher proportional amount than gaming devices 120d and 120e (located at positions 2 and 6, respectively). Gaming devices 10 120f and 120g are not awarded a prize as they are located more than the specified number of devices away from the first gaming device 120a. Persons skilled in the art will appreciate that value of the 15 secondary prize can vary depending on the actual implementation. For example, in some implementations, the secondary prize value will vary as a function of time or as a function of the value of the jackpot prize pool. 20 In an embodiment, should the jackpot controller 110 determine that one of the devices to be awarded the secondary prize is not active (e.g. it has not contributed to the jackpot pool for a specified period of time), then the prize to be awarded to that device can either be passed on to the next adjacent 25 device or put back into the jackpot prize pool. It is envisaged that other re-distribution arrangements may also be implemented depending on the actual arrangement of the linked devices.

- 16 An indication as to the identity and/or location of the first gaming device 120a is provided to further facilitate interaction between players. In one implementation, the location and/or identity of the first gaming device 120a is 5 displayed on the display module of each gaming device awarded the secondary prize. For example, a flashing arrow points in the direction of the first gaming device 120a. In addition, the first gaming device 120a can advertise its position by providing a visual or auditory alarm. 10 The method of the invention is summarised in Figure 7. At step 702 it is determined that a first gaming device participating in the gaming event is to be awarded a primary prize. Responsive to determining that the primary prize is 15 to be awarded, at step 704, the jackpot controller 110 determines at least one second gaming machine to award a secondary prize. The determination is based, at least in part, on the location of the second gaming device with respect to the first gaming device. In a final step 706, the 20 primary prize and secondary prize are awarded to the first gaming device and at least one second gaming device, respectively. In an alternative embodiment to that described above, the 25 positional map stored by the database 528 specifies the actual location of each gaming device. For example, Cartesian co-ordinates of each of the linked gaming devices are input in association with the unique gaming device identifier. In such an embodiment, the jackpot controller 30 can be arranged to award secondary prizes to gaming devices located within a specified distance, or radius, of the primary prize-winning device. In an alternative embodiment, the requirement may also specify the direction or orientation - 17 of the at least second gaming device with respect to the first gaming device. In this manner, gaming operators or the like can specify individual rows or banks in which the at least one second gaming device is to be located. In an 5 embodiment, the relative location of each gaming device is determined by the gaming devices themselves by using conventional wireless triangulation locating methods and then communicated to the jackpot controller to build the positional map. 10 According to embodiments of the present invention, non primary-prize winning gaming devices can be determined for awarding a secondary prize, with the determination based at least in part on the location of the non primary-prize 15 winning gaming device with respect to the primary prize winning gaming device. According to such a technique, the sense of community among linked players may be increased and as a result the overall enjoyment experienced by the players. 20 It will be appreciated by persons skilled in the art that numerous variations and/or modifications may be made to the invention as shown in the specific embodiments without departing from the spirit or scope of the invention as broadly described. The present embodiments are, therefore, 25 to be considered in all respects as illustrative and not restrictive. It is to be understood that, if any prior art publication is referred to herein, such reference does not constitute 30 an admission that the publication forms a part of the common general knowledge in the art, in Australia or any other country.
