Description
BACKGROUND INFORMATION

Slot machines and other wagering games capable of being played within similar cabinets in casinos and other gaming establishments have been very popular. In a typical configuration, rows of cabinets offering the same of similar games are set up with each cabinet touching the one next to it. To perform maintenance on these cabinets or to change the type of game being offered in the cabinet, it is often necessary to shut down the game and pull the cabinet out of the row it is in and into the area where players normally sit. This in turn usually requires other games around the cabinet being worked on to be shut down as well.


While a computerized slot machine, which does not include any physical components other than an interactive display, can be readily reprogrammed to provide a different game, the type of game is limited to just what can be displayed. There is no opportunity to replace the display with a different type of game, such as one that incorporate mechanical elements into the game as well. To offer that type of game in place of the slot machine, the entire cabinet would have to be removed and replaced. If the new cabinet is not exactly the same as the prior cabinet, the new cabinet may not align well with other cabinets in the same row, giving the row an awkward and unappealing appearance. Further, whether a cabinet has to be pulled out for maintenance or repair or conversion to another game or a cabinet has to be replaced, such operations are disruptive to the gaming area, require multiple machines to be shut down, and can significantly increase costs while revenue is lost.


It is also desirable to be able to provide a wide array of different games within a gaming cabinet, including dice, wheel and balls games that rely on gravity, such as roulette. The size of the cabinets, however, is problematic because the roulette wheel needs more horizontal space than is available. Yet, turning the roulette wheel vertical makes it impossible to spin a ball around the roulette wheel, which is critical to the game.


TECHNICAL FIELD

The present disclosure relates generally, but not exclusively, to the field of gaming, particularly gaming cabinets for different games, including roulette.


SUMMARY

FIG. 1 illustrates a base 100 for a universal cabinet for a variety of different games that may be connected to a top 101 of an upper section 102 of the base 100. The base 100 may further include a lower section 103 on which the upper section rests. As further illustrated in FIG. 3 and FIG. 4, the base 100 may include a number of exterior elements that provide visual and audio effects that serve to either attract attention to the game, so as to entice someone passing by to play a game offered by the universal cabinet, or to enhance the play of a game being played in the universal cabinet.


The exterior elements may include soft touch gel buttons, such as buttons 104 and 106, gel arm rests 108 at the bottom of the upper section 102 where a players arms would rest for extended periods of time, and a control button 110 that may be used for different games. Other lighting effects that may be provided include gel LED modules 112 of different sizes and shapes and an ambient LED 114 that illuminates the bottom section 103 from underneath the upper section 102. The upper section 102 may further include a money/credit/card receiving/payout mechanism 116 and a display 118. Speakers 120 in the lower section 103 may provide some or all of the sound, depending on the nature of the game being played. A foot rest 122 may also be built into the lower section 102.


The inside of the universal cabinet may include a controller module 200 that may provide common connections for each of the different types of toppers and provide a USB connection to an embedded computer (not shown) in the bottom section 103. The embedded computer may be a GANLOT AMDY-7005, which is designed for gaming applications. The controller module 200 may also provide outputs for the base cabinet lighting and buttons, which makes it possible to offer numerous gaming machine lighting designs. The controller module 200 may also make it possible to quickly change toppers on the base 100. Only the upper section 102 may need to be removed to access the controller module 200. Connections from the existing topper may be disconnected and the topper removed from the upper section 102. The new topper may then be attached to the upper section 102 and its connections plugged into the controller module 200. In an embodiment, a switch in the controller module 200 may then be switched to correspond to the new topper. In other embodiments, the new topper can be identified by connecting or plugging one or more additional modules for that topper into the controller module 200 or changing a program of the embedded computer. This may make it possible to quickly change the type of game that is being played on the universal cabinet base 100 without have to remove the base 100 from any row it is in and without moving other machines or forcing the other machines to be shut down. The may also make it possible to prototype and develop other toppers for new games, further reducing development and production costs.


As previously note, FIG. 3 and FIG. 4 further illustrate the base 100 of the universal cabinet when a seat 300 and a tall curved display topper 302 have been connected. In addition to the speakers 120 built into the lower section 103 of the base 100, such as a 50 Watt/4 Ohm subwoofer speaker, the seat 300 may include additional speakers 402, such as two 25 Watt/8 Ohm speakers in an upper section 403 of the seat 300. Additional speakers may be included in the topper 302, such as two 25 Watt/8 Ohm speakers 408 at the top of the topper 302 and two 25 Watt/8 Ohm speakers 410 at the bottom of the topper 302. In addition to those speakers, a 50 Watt/4 Ohm rumble speaker 404 may be provided in the bottom section 405 of the seat 300. This many speakers may enable a variety of audio effects, especially if a range of speaker types are used, including tweeters, midranges and subwoofers or woofers.



FIG. 5, FIG. 6, FIG. 7 and FIG. 8 illustrate different types of topper that may be added to the base 100 as previously discussed. These toppers include the dice topper 500 of FIG. 5, which enables craps and similar types of dice games to be played. The base 100 includes a random generator (not shown) for controlling the randomness of the dice roll in order to make game fair. Even though the dice are being tossed as part of the game in the see-through section 502 of the dice topper 500, the game cycle speed may be just as fast as slot machine game cycles, thereby providing a different and more exciting form of a game with at least the same revenue potential as a slot machine being played for the same period of time. Depending on the type of game incorporated into the topper, the base 100 may send random results for the game to the topper and in other cases the topper may send the random results to the bottom. For example, in the dice game, the resulting throw of the dice may be randomly effected by a random generator in the base, but the resulting throw cannot be predetermined so it has to be determined at the topper and then sent to the base 100.



FIG. 6 illustrates to card game toppers, a baccarat topper 602 and a blackjack topper 604. Each of the card mechanism 606, such as a SUZO card flipper module, may flip cards under control of the random generator. The card decks can be varied depending on the game, such as a classic deck with or without jokers, and cards including the back sides of cards so cards can be covered. FIG. 7 illustrates a display card topper 700 where the display is wider than tall, which may allow higher resolution display. FIG. 8 illustrates two different versions of vertical roulette toppers 802 and 808. Vertical roulette topper 802 includes a roulette wheel 804 and signage 806 on top of the roulette wheel 804, while vertical roulette topper 808 includes an additional display 808 on top of which is mounted a roulette wheel 812 and signage 814.


As illustrated in FIG. 9 and FIG. 10, the vertical roulette wheel 900 includes a stationary roulette ball 902, which is shown mounted to a non-moving portion of the wheel 900 near the top, although other positions are possible. Since the roulette ball 902 does not move, the numbers do, which may be accomplished by mounting a circular ring of numbers on a transparent or translucent number wheel 904 that can be rotated based on the random generator of the base 100. To simplify the electro-mechanics associated with rotating the number wheel 904, the number wheel 904 may be sufficiently translucent that LED lighting 906 provided behind the numbers is clearly visible. The LED lighting 906 circuit board is illustrated in FIG. 10. The numbers themselves may be physically printed or attached to the number wheel so they can be illuminated by the LED lighting 906. In play, the random generator may determine an amount of force to be applied to rotate number wheel 906 or the random generator may determine when a breaking force will be applied to the number wheel 906 or a combination of both.
