BACKGROUND OF THE INVENTION
The present invention relates to an apparatus and method for gaming and, particularly, but not exclusively, to an apparatus and method for displaying gaming related information.
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 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 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 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 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 information. The provision of separate displays or displays which provide different gaming and advertising information from the “main” game played on the machine, 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 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 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 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, 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 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.

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 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.
As discussed above, FIG. 2 shows a representation of a display apparatus 40 in accordance with an embodiment of the present invention, which is arranged to be mounted to an EGM. The display apparatus 40 provides a display 41 which can be used in addition to the main display 16 (and also any secondary display in the top box 26) of the EGM 10. The display apparatus 40 may be controlled, in this example, by the EGM 10. It also may be controlled by an external device, such as a Casino server or jackpot controller (e.g. implemented by the jackpot server 207 shown in FIG. 5). Information relating to the EGM may be displayed by the apparatus 40 under the control of the EGM, or information required to be displayed on the apparatus 40 by the server or jackpot controller may be displayed.
A display apparatus 40 is in this case is in the form of a housing separate to the EGM 10 which mounts a display unit and display circuitry. The housing is arranged to be mounted to the EGM 12 by mounting apparatus, such as interfering mechanical arrangements, screws, nuts and bolts, or any other convenient fashion. In some embodiments, electrical or wireless connections may be made between EGMs circuitry and the display circuitry and/or between a network to an external device and the display circuitry of the display apparatus.
The display apparatus can take different outward forms. For example, FIG. 6, FIG. 7, FIGS. 9 and 10 show different types of EGMs, which may play different games. Although not described in detail here, they will have similar architectures to the EGM described with reference to FIG. 2. They may be programmed to play different games, may have different types of displays, etc, but generally their purpose is to play games for entertainment.
Each of the EGMs in FIGS. 6, 7, 9 and 10 have a display apparatus in accordance with an embodiment of the present invention mounted thereto. Referring to FIG. 6, for example, the slant top EGM 300 is in this case provided with a primary video display 301 for playing a game where a plurality of symbol bearing reels are emulated by the video display 301. The player interface and components of the EGM 300 are similar to those described with reference to FIG. 2, although the external shape of the EGM 300 is different and it may be arranged to play a different game. Mounted to the top box 302 of the EGM 300 is a separate display apparatus 303 including a display screen 304 which in this case has been retro-fitted to the EGM. The display apparatus 303 comprises a display controller 402 which has been programmed to interface with a display controller of the EGM (e.g. using the same protocols, drivers, or any other necessary software/hardware). In this embodiment, the display apparatus 303 is oval in shape.
Referring to FIG. 7, an EGM 310 of the form having actual reels 311 driven by stepper motors is illustrated. Attached to a top box 312 of the EGM 310 is a display apparatus 313 in accordance with an embodiment of the invention. This has a display 314 and is also generally oval in shape.
FIG. 8 shows a display apparatus 330 in accordance with the present invention shown separate from the EGM. The housing 331 mounts display circuitry and a display 332. In this embodiment, the display apparatus 330 is shown displaying particular artwork for a particular game played on the type of EGM illustrated in FIG. 9 as EGM 340. The display 332 is a video display, and can therefore display any artwork in either static or dynamic forms under the control of the EGM 340 (in this embodiment). It will be understood by persons skilled in the art that the display apparatus 330 could advantageously be mounted to a different type of machine, playing a different game, and, under control of the controller of the EGM, display different artwork (and, indeed, any information that it is required to display).
Referring to FIG. 10, a further type of EGM 350, again having stepper reels 351, is illustrated. A display apparatus 352 in accordance with an embodiment of the present invention, is mounted to the top box 353 of the EGM 350. The display apparatus 352 is of a different and “fancy” shape to that of the other illustrated embodiments. It includes a video display 353 and also artwork 354.
The display apparatus of embodiments of the present invention may be formed by any conveniently shaped housing. The housing may or may not include artwork, but will include a display, which may be a video display, which can be controlled by the EGM or another external device to display information as desired by the EGM or other external device.
Referring to FIG. 11, a display apparatus 401 in accordance with the present invention, comprises a display 400, which in this example is a LCD (liquid crystal display). It may be any other type of display in other embodiments, however, such as vacuum fluorescent display (VFD), an LED display, plasma display or any other display of any shape or size.
The display apparatus 401 also comprises display circuitry, in this embodiment being in the form of a display controller 402 which includes a processor and associated memory for intelligently controlling the display apparatus 401. The display circuitry in this embodiment also includes an input/output interface 403 which includes a wireless communication facility 404 and also a hardwired connector 405 for connecting to external circuitry, such as contacts from an EGM or other external device. This embodiment therefore has the option of a hardwired connection or a wireless connection. The 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 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 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.
FIG. 12 illustrates just one way in which a display 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 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 FIG. 11. In this 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 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 example, referring to FIG. 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, 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 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.
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 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 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 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 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 depending upon game themes.
