The method of Description The present application claims priority from GB Patent Application No. 0420125.7, filed on Sep. 9, 2004. The present invention relates to games of chance involving roulette wheels and, more particularly, but not exclusively to a game of chance involving multiple roulette wheels. Games of chance are highly popular and have been around for many centuries. One especially popular game of chance is roulette, which is believed to have been around in something close to its present form since the 18 Traditional roulette is based on a single wheel, and is generally played at a casino where a wheel is mounted on a table and a cloth or like marked spread is provided to enable each player to indicate his predictions. The wheel is set near the center of the table. As indicated above, certain of the numbers and spaces on the roulette betting felt (such as 2, 4, 6, 8, 10, 11, 13, 15, 17, 20, 22, 24, 26, 28, 29, 31, 33, and 35) are colored black, while others (such as 1, 3, 5, 7, 9, 12, 14, 16, 18, 19, 21, 23, 25, 27, 32, 34 and 36) are colored red. Also included on the betting felt are spaces for such bets as: “manqué” (1 to 18 inclusive); “pass” (19 to 36 inclusive); “pair” (an even number); “impair” (an odd number); “rouge” (a red number); and “noir” (a black number). Therefore, the winning bet may be comprised of a bet on the particular winning number, a bet on a range of numbers that includes the winning number (e.g., on odd or the “2 All bets are placed against the house and are indicated by placing stakes (e.g., chips) on the particular numbers or types of bets selected as they appear on the table. Once the bets are placed, the “croupier” spins the wheel in one direction and tosses the ball onto the wheel in the other direction. The sector where the ball finally comes to rest is the outcome, thereby indicating the winning number and color. This information is then used to manually determine which of the bets are winning bets. Various betting combinations with different odds and maximum bets are allowed depending on the rules of the gaming establishment. The standard odds and payouts for traditional roulette are well known in the art. One way of increasing the possibilities in a game is to increase the number of balls that circulate with the roulette wheel, thus increasing the number of outcomes that can be bet on. An example is shown in U.S. Pat. No. 6,209,869 to Mathews, which discloses an apparatus and method for playing a roulette-type game. The apparatus includes a conventional roulette wheel and four tables. Each table has a lower playing field and an upper playing field, wherein each field is utilized for placing bets. During play, four balls are utilized on the one wheel, wherein each ball corresponds to one of the tables. The lower field is utilized for placing bets on the single ball that is associated with that particular table, while the upper field of each table is utilized for placing bets on all of the balls in play. U.S. Pat. No. 5,755,440 to Sher relates to an apparatus used to play roulette using multiple balls. The apparatus includes a single roulette wheel that has multiple tracks, thereby permitting two or more balls to be propelled into the wheel simultaneously. The mechanical systems above can be simulated electronically, and both stand alone roulette machines and computer programs for playing roulette are well known. The computer programs may be stand alone programs or can be played by remotely located participants over the Internet. U.S. Pat. No. 5,259,616 to Bergmann discloses a coin-operated gaming machine that has a roulette-like number pan and a setting keyboard. In operation, the player inserts one or more coins into a coin insertion slot. The player then selects which numbers the player wishes to bet on using the keyboard. After the player places a bet, a random number generator randomly determines the winning number, and that number is then highlighted on the number pan. The random number generator also randomly determines a win multiplier number by which the winning payout is multiplied. U.S. Pat. No. 6,083,105 to Ronin et al. discloses a single-player computerized roulette playing apparatus. The apparatus includes a rotatable roulette wheel that is mechanically rotated using a drive mechanism. One or more balls are put into play during the game. A roulette game field is displayed on a corresponding computer display, which provides a means by which the player can place one or more bets. Recently, a system intended for Internet based betting or for a betting machine, provides for a series of roulette wheels and allows a player to take a betting position that takes into account the results at each of the roulette wheels in the series. The system thus allows for results with odds that are lower than 37/1 and thereby permits higher payouts, but only in a limited way. Such a system is exemplified by International Patent Application No. WO 2004/054665, which teaches a computerized multiple wheel roulette game allowing players to place bets on different wheels and on multiple numbers on the same wheel. The idea is to permit bets with lower odds and thus to permit larger prizes. The game is based on individual results produced on individual wheels and, since these are independent events, the use of the individual results does not succeed in giving a level of odds and consequent maximum prize, which can stand out against national or state lotteries and other available games of chance. There is thus a widely recognized need for, and it would be highly advantageous to have, a game of chance based on roulette wheels which is devoid of the above limitations. According to one aspect of the present invention there is provided a method of playing roulette using a plurality of wheels having discrete stopping positions, each stopping position being a discernable result, the method comprising: -
- receiving at least one player's prediction of an accumulated result possible for the plurality of wheels,
- operating the plurality of wheels to cause each wheel to reach one of its stopping positions at random, thereby to give one of the discernable results,
- calculating an accumulated result for the plurality of wheels by adding the discernable results, and comparing the accumulated result with the at least one player's prediction to identify a winning prediction.
In a particularly preferred embodiment the method uses five roulette wheels, as this gives a level of odds that are seen as an ideal balance between the level of the prize and the chances of actually winning. The wheel being used may be the traditional European version having 37 stopping positions, or it may be the traditional USA version having 38 stopping positions. As a further alternative the wheel may make use of any other suitable format. There exist for example various historical formats of the roulette wheel which are not in widespread use today. The method may use a dedicated electronic slot machine. Alternatively, the method may use a dedicated mechanical device, for example a device in which a given number of wheels are arranged in a column. A single spin action by the operator sets all of the wheels spinning but they come to rest independently. Preferably the stopping positions are electronically detected and the sum of the stopping positions is indicated at an output. Alternatively the method may be played using a computer program, which simulates the spin of the roulette wheels. The computer program may be stand alone or support play with one or more remote users over an electronic network, say between a server and a client. According to a second aspect of the present invention there is provided a device for playing a game of chance comprising: -
- a plurality of roulette wheels each spinnable to provide a result, and
- an accumulator for calculating and outputting a sum of the results of the plurality of roulette wheels.
A preferred number of roulette wheels is five roulette wheels, again for providing a trade off between the ability to provide a large prize and a reasonable possibility of actually winning. As above, the wheels concerned may be in the US format or the European format. Alternatively they may be in any other suitable format. The wheels may be physical wheels, irrespective of whether the accumulation is carried out electronically, mechanically or left to the users. In an alternative device the wheels are implemented virtually. As discussed above, the virtual implementation may be provided over a network, such as the Internet, to enable participation by remotely located participants or players. According to a further aspect of the present invention, there is provided a method of providing a game of chance having a non-linear mapping of probabilities to each of a plurality of different outcomes, the method comprising: -
- providing a plurality of roulette wheels each spinnable to provide a result, and
- providing an accumulator, in association with the plurality of roulette wheels, for calculating a current one of the plurality of different outcomes, the current outcome comprising a sum of the results of the plurality of roulette wheels.
According to a further aspect of the present invention there is provided a method of providing a game of chance having a non-linear mapping of probabilities to each of a plurality of different outcomes, the method comprising: -
- using a plurality of wheels having discrete stopping positions, each stopping position being a discernable result, the method comprising:
- operating the plurality of wheels to cause each wheel to reach one of its stopping positions at random, thereby to give one of the discernable results,
- calculating an accumulated result for the plurality of wheels by adding the discernable results, the accumulated result providing the outcome, and
- comparing the outcome with the at least one player's prediction to identify a winning prediction.
The non-linear mapping is typically a bell-shaped distribution about a median, the median being the sum of the median results of each wheel of the plurality of wheels. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The materials, methods, and examples provided herein are illustrative only and not intended to be limiting. Implementation of the method and system of the present invention involves performing or completing certain selected tasks or steps manually, automatically, or a combination thereof. Moreover, according to actual instrumentation and equipment of preferred embodiments of the method and system of the present invention, several selected steps could be implemented by hardware or by software on any operating system of any firmware or a combination thereof. For example, as hardware, selected steps of the invention could be implemented as a chip or a circuit. As software, selected steps of the invention could be implemented as a plurality of software instructions being executed by a computer using any suitable operating system. In any case, selected steps of the method and system of the invention could be described as being performed by a data processor, such as a computing platform for executing a plurality of instructions. The invention is herein described, by way of example only, with reference to the accompanying drawings. With specific reference now to the drawings in detail, it is stressed that the particulars shown are by way of example and for purposes of illustrative discussion of the preferred embodiments of the present invention only, and are presented in order to provide what is believed to be the most useful and readily understood description of the principles and conceptual aspects of the invention. In this regard, no attempt is made to show structural details of the invention in more detail than is necessary for a fundamental understanding of the invention, the description taken with the drawings making apparent to those skilled in the art how the several forms of the invention may be embodied in practice. In the drawings: The present embodiments comprise a system and method for playing multiple wheel roulette in which a final result on which players place bets is an accumulated or otherwise combined total taken from the results of the different wheels. In a further aspect the present embodiments provide a game with a plurality of possible outcomes and a non-linear probability curve defining the likelihood of the different outcomes. More specifically but not exclusively the non-linear probability curve is a bell curve or a Gaussian distribution or like statistical distribution about a median or mode. The system and method may be played using multiple standard roulette wheels used together or it may be played using a dedicated mechanical machine including the multiple wheels needed for the game or it may be played using an electronic slot machine or it may be played over the Internet or like electronic network, for example using a server-client type connection. The principles and operation of a multiple wheel roulette system or method according to the present invention may be better understood with reference to the drawings and accompanying description. Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments or of being practiced or carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein is for the purpose of description and should not be regarded as limiting. Reference is now made to Reference is now made to The number of roulette wheels can be selected according to the desired maximum odds it is intended to provide. Thus a game provider wishing to provide odds of a million to one so that he can advertise a million dollar maximum prize, would select an appropriately large number of roulette wheels. A typical application would include say five roulette wheels, although herein, at least partial probability tables are given for all possibilities between two and nine wheels. Reference is now made to It is of course appreciated that stages one and two need not be successive. It is common in roulette to continue to place bets up to a certain point in the spin of the wheel. Once the wheels have settled at their stopping positions then the numbers of the different stopping positions are taken in stage S In a final stage S It is pointed out that as well as placing bets on the accumulated total, it is also possible to place bets on individual outcomes, for example will a three appear on any of the wheels, or will a three appear on any specific wheel. Reference is now made to Reference is now made to It will be appreciated that for any given number of wheels, possible summation results range from zero to the number The importance of the above is that the summed roulette game as described here is very different from traditional roulette because the graph of the odds is essentially a bell curve, whereas with the traditional game it is a flat curve. This enables the game designer to offer different odds for different sums and thus advertise a maximum prize which is in fact extremely high, even though the overall chances of wins of some kind occurring is not that small. As explained above, the idea of using multiple roulette wheels is to provide the possibility of predictions with lower odds, so that larger prizes can be paid. In the following tables, odds are given for different results using different numbers of wheels. Tables 1 to 8 below represent the probabilities for the most likely outcomes when spinning a number of roulette wheels and calculating the sum of all the individual outcomes. For each number of wheels the Mode sum is given, indicated by shading, as well as the corresponding probability of occurrence. Also given are the probabilities of obtaining the five closest sums to the Mode, 5 on each side. It is noted that the probabilities for getting mirroring sums around the Mode are the same as the distribution is symmetric. The calculations were carried out using a counting algorithm that works in a recursive fashion and counts the number of times each sum occurs when adding an additional roulette wheel. The probabilities are obtained by dividing the number of observations by the size of the population of possible results.
It is clear from table 9 that the best odds available to the player are for the sums about the mode. The game designer is able to offer a flat level of odds over the entire table or he can offer a curve of odds, thus offering a very high maximum prize for the sums towards the ends of the table.
Tables 10 and 11 show for the two separate cases of the European and the US format of roulette wheel the probability that a given number from 1 to 36 will appear on no wheels, on exactly one wheel etc up to five wheels. The second row shows the chances of a number from 1 to 24 will appear on no wheels, on exactly one wheel etc up to five wheels. The third row shows the same calculation for numbers from 1 to 18 and then the remaining lines are for individual numbers. Winning Table 5 Roulettes
