Description

AUSTRALIA Patents Act 1990 COMPLETE SPECIFICATION Standard Patent Applicant: Aristocrat Technologies Australia Pty Limited Invention Title: AN APPARATUS AND METHOD FOR GAMING The following statement is a full description of this invention, including the best method for performing it known to us: P76506.AU PatSet_Fin Appication 2009-5-8.doc (S) 589798_1 (GHMatters) - 2 AN APPARATUS AND METHOD FOR GAMING Field of the Invention The present invention relates to an apparatus and 5 method for gaming and, particularly, but not exclusively, to an apparatus and method for displaying gaming related information. Background of the Invention 10 Gaming is implemented by many types of gaming systems, providing many different types of games. These include traditional type casino games, such as roulette, Keno, bingo and many others, all of which may nowadays be implemented in electronic form (in many cases utilising 15 video display screens). These also include gaming systems which comprise a game controller arranged to control the random display of several symbols from a pre-determined set of symbols and to determine a game outcome such as a game win, based on the displayed symbols. Such gaming 20 systems may commonly be implemented as a stepper machine provided with reels, with each reel carrying several symbols of the set, or a video machine wherein selected symbols are displayed on virtual reels in a graphical display device. Win outcomes can occur based on symbols 25 appearing on one or more horizontal lines, diagonal lines, or in any other pre-determined way. Known gaming systems and gaming machines (such as Electronic Gaming Machines, "EGMs"), use various lighting and sound effects to attract, stimulate and entertain 30 players, and also to provide information on progression of a game, which may be an individual game played on the machine or a linked game played by several players. Separate displays may be provided for displaying different information on different games, advertising or other 35 information. The provision of separate displays or displays which provide different gaming and advertising information from the "main" game played on the machine, C:\NrPortbl\GHMatters\MARKO\1791245 1.DOC 25/09/09 -3 may require construction of expensive apparatus, particularly where the displays are implemented in an EGM. In some gaming apparatus, such as EGMs, a "main" display may be provided for displaying aspects of a main 5 game, for example symbol selection games such as discussed above, and a secondary display, usually mounted above the main display in a "top box", may be provided to display other information. The other information may include information on other games, such as games played on the 10 EGM, progressive jackpot levels, and/or various illuminated or video artwork associated with the EGM. These secondary displays are part of the EGM and therefore add to the expense of the EGM. They are designed specifically to operate within and as part of the 15 EGM. It is known to provide "toppers" which are separate displays units that may be mounted to an EGM. Commonly, toppers merely display artwork (which may be illuminated) associated with the EGM or are driven by another device, 20 such as a jackpot controller, for example, to show the progression of a linked jackpot. These toppers are usually machine specific. That is, they are designed for particular EGM, or a particular linked game. Typically these toppers are in the form of backlit printed glass 25 bearing the name of the game. Inasmuch as the printed glass is a fixed medium, the toppers have been designed to identify the game to players from a distance so the players can find the game among other games on the casino floor. 30 Summary of the Invention In accordance with a first aspect, the present invention provides a display apparatus for a gaming system, comprising a display unit arranged to be mounted 35 to an Electronic Gaming Machine (EGM), and display circuitry arranged to control the display unit, the display circuitry being arranged to communicate with an C:\NrPortbl\GHMatters\MARKO\17912451 .DOC 25/09109 - 4 EGM controller to display information under a control of the EGM controller.

This embodiment therefore has the option of a hardwired connection or a wireless connection. The 20 invention is not limited to this. Other embodiments may have hardwired or wireless connections, but not both. As previously mentioned, the controller 402 may be programmed with the necessary software and hardware to communicate with (and more particularly receive display instructions 25 from) a device coupled to the apparatus by way of the input/output interface 403. In this embodiment, speakers 406 for providing audio outputs are provided. This embodiment is therefore an intelligent 30 device 401 which can be selectively controlled by an EGM or other external devices to display information on a display 400 required by the EGM and/or other external devices. Figure 12 illustrates just one way in which a display 35 apparatus in accordance with an embodiment of the present invention may be utilized. A plurality of different EGMs 501, 501 and 503, are each provided with a generic C:\NrPortbl\GHMatters\MARKO\1791245 .DOC 25/09/09 - 20 topper unit display apparatus 504, in accordance with an embodiment of the present invention. The display apparatus 504 includes a display and the other components described with reference to Figure 11. In this 5 embodiment, the topper display apparatus 504 may be controlled by the Casino server 500 which is hardwired (via contacts 405, for example) to communicate with the display controller 402 to control displayed information on the display apparatus 504, as desired by the Casino io server 500. The topper display apparatus 504 is selectively connectable to the EGM 501, 502, 503 controller to display information under control of the EGM controller. It will be appreciated that many other ways of utilising the display arrangement are available. For 15 example, referring to Figure 5, display apparatus 250 in accordance with embodiments of the present invention may be used with a "downloadable" EGM, which is configured with software from a server to play different games, depending upon the software downloaded to it. Similarly, 20 the display apparatus 250 may be driven to show different information depending upon the software downloaded to the configurable EGM 203. As discussed above, the display apparatus can be driven/controlled by the EGM itself or any other external 25 device. The display controller 402 communicates with the EGM's controller. In some embodiments it is also possible that the display may be controlled directly by the EGMs controller and/or external device. Connectivity is wired, wireless, or a combination of both, as discussed above. 30 Audio may be generated through the EGMs controller, or external device, or the topper unit 401 may have its own audio programmed in. Advantages of using this type of intelligent display apparatus are many and it can have many applications. It 35 may be used in an attract mode, for example, to attract players to the slot machine or EGM, to display Casino promotions, information on Casinos, games and other C:\NrPortbl\GHMatters\MARKO\17912451 .DOC 25/09/09 - 21 matters. It does all this without compromising any space within the EGM it is mounted to. A topper unit may be utilised on a bank of several EGMs to display live synchronised video streams 5 animations, graphics, synchronised with sound. It can also be used as a stand alone unit on a single EGM (as discussed above) and linked to the game as part of a game feature, or may be controlled independently of game theme. Additionally, the topper unit may be used for 10 community gaming, group gaming or peer to peer gaming to display video, animation and/or sound based on different game themes. It can also be controlled by a jackpot controller, for example, to display jackpot/progressive information as needed and/or to display bonusing features 15 depending upon game themes. As discussed above, the topper unit also can be used with configurable or downloadable EGMs. When the downloadable EGM is updated with a different gaming and/or theme the topper unit may be updated at the same time or 20 controlled by the EGM to be updated, so that the topper can remain consistent with the EGM game/theme. The display controller of the gaming apparatus may include software (stored in memory) configurable to enable it to communicate with EGMs of different types and/or 25 external devices of different types. In the above embodiment, the display apparatus includes a processor arranged to control the display apparatus. The invention is not limited to this. Other embodiments may include display circuitry enabling the 30 display to be directly controlled by the EGM and/or external device. Note that the term "electronic gaming machine" is not limited to machines which play reel-type games. Other games, such as roulette, Keno, bingo and many others may 35 be played on EGMs and display apparatus of the present invention may be used with EGMs playing these types of games. C:\NrPortbl\GHMatters\MARKO\1791245 1.DOC 25/09/09 - 22 In the above embodiment, the display apparatus are removable and selectively mountable on different types of EGMs. In an alternative embodiment, the display apparatus may be non-removable and permanently attached to an EGM. 5 It will be appreciated that programme code may be necessary to some embodiments for, for example, enabling the display apparatus controller to communicate with the EGM and/or external device. Any programme code may be supplied in a number of ways. For example, on a computer 10 readable medium, such as a disc or a memory, or as a data signal (for example, by downloading it from a server). 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 15 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. 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 25 are, therefore, to be considered in all respects as illustrative and not restrictive. C:\NrPortbl\GHMatters\MARKO\1791245 .DOC 25/09109
