(Not applicable)




BACKGROUND OF THE INVENTION




(1) Field of the Invention




The present invention relates generally to a roulette-type game, and more particularly to an improved method for playing such a game, utilizing a plurality of balls.




(2) Background Information




Gambling and games of chance are popular sources of entertainment for many people. Such games of chance are more enjoyable if a variety of different gaming apparatus are available to the player. New forms of gaming apparatus and new methods of playing existing games can generate new interests and enthusiasm in this activity.




One game that has been popular through the years is the game of roulette. In this game, a single rolling ball is propelled around a generally circular track in a direction opposite the rotation of a central wheel. Wagers are placed on the likelihood of the ball landing in a particular pocket or cassette formed around the perimeter of the central wheel.




While roulette has been a gaming apparatus present in casinos for many years, it has been becoming less popular in the recent past. While many reasons have been given for this reduction in popularity, today's gamblers have found conventional roulette to be “boring” and “too predictable” a game.




BRIEF SUMMARY OF THE INVENTION




It is therefore a general object of the present invention to provide an improved method for playing a roulette-type game.




A further object of the present invention is to provide a method for playing a roulette type game, which permits betting on the number of balls which may simultaneously fall within a single pocket, or within a specified group of pockets.




These and other objects will be apparent to those skilled in the art.




The method for playing a roulette-type game of the present invention includes the steps of:




(A) providing a first playing field for betting on the conclusions of a plurality of gaming trials, wherein the playing field restricts bets on at least one of the plurality of conclusions of each trial, to thereby create a house advantage;




(B) placing a bet as to the conclusions of each of the trials;




(C) initiating the trials;




(D) identifying the conclusions of each of the trials; and




(E) determining winning and losing bets for the serial of trials.




The payout ratio for a winning bet includes the steps of:




(A) determining the house advantage for the playing field;




(B) determining a cumulative house advantage for the playing field;




(C) determining a single trial bet probability;




(D) multiplying the single trial bet probability times itself with an exponent equal to the number of trials in the game to produce a multiple trial bet probability;




(E) determining a payout variable by inverting the multiple trial bet probability to form a fraction having 1 as the numerator;




(F) determining a payout ratio numerator by multiplying the payout variable by the cumulative house advantage; and




(G) designating the payout ratio denominator as 1.

.




Referring now to

FIG. 2

, a layout of the preferred embodiment of the roulette game of the present invention is shown in more detail. The roulette wheel


10


is preferably located generally centrally among four radially projecting tables


42


,


44


,


46


, and


48


. In order to associate each table with one of balls


26


, it is preferred that each table have a colored top matching the color of the particular ball. Thus, in this case, table


42


is identified as a blue table and is associated with a blue colored ball


26




a,


table


44


is red and is associated with a red ball


26




b,


table


46


is purple and is associated with the purple ball


26




c,


and table


48


is green and is associated with green ball


26




d.


A vertical electronic display post


50


is provided for each table


42


,


44


,


46


, and


48


, and is located proximal the roulette wheel


10


and each table. Each post


50


has electronic display apparatus for displaying the number of the pocket within which the associated colored ball falls during play of the game. Thus, post


50




a


displays the location of blue ball


26




a,


post


50




b


shows the location of red ball


26




b,


post


50




c


shows the location of purple ball


26




c,


and post


50




d


shows the location of green ball


26

Each pocket


22


includes a plurality of sensors


52


, each operable to detect one of the four balls


26




a,




26




b,




26




c,


and


26




d.


The sensors are shown in only one pocket in the drawings, and are well known in the art and will not be described in further detail herein. The sensors


52


are electrically connected to posts


50


to transmit information for display thereon. Posts


50


are preferably mounted to permit viewing from all four tables


42


,


44


,


46


, and


48


.




Each table


42


,


44


,


46


, and


48


includes a lower playing field


54


and an upper playing field


56


, upon which bets are placed for the roulette game. Playing fields


54


and


56


are identical on each table, and therefore only table


48


will be described in detail hereinbelow.




Referring now to

FIG. 3

, the green table


48


is shown in more detail. Table


48


has an upper and lower playing field


56


and


54


, the upper playing field


56


utilized for placing bets on the plurality of balls


26


, while lower playing field


54


is utilized to place bets on the single ball


26


which is associated with that particular table. In this case, lower field


54


would be utilized to place a bet on the green ball


26




d.


Lower playing field


54


is arranged in a conventional fashion for American roulette, having a “0” and a “00” on the wheel. Thus, the player may place any of the following different bets:





















Number of Numbers








Name of Bet




Covered by Bet




Payout Ratio




























A - Straight




1




35/1 







B - Split




2




17/1 







C - Street




3




11/1 







D - Square




4




8/1







E - Line




5




6/1







F - Line




6




5/1







G - Dozens




12




2/1







H - Columns




13




2/1







I - High or low




18




1/1







J - Black or red




18




1/1







K - Even or odd




18




1/1















Sample locations for each of the above-identified bets are marked on the lower table


54


with the letters A, B, C, D, E, F, G, H, I, J, K, respectively. Thus, it can be seen that the roulette game of the present invention may be played in the conventional fashion, placing bets on the ending location of a single ball into one of the pockets


22


.




The addition of the upper playing field


56


permits new possibilities previously unknown in a roulette-type game. Upper field


56


is the same as lower field


54


, but with the addition of two additional betting boxes


58


and


60


. In the preferred embodiment of the invention, four balls are in play, and box


58


permits a bet of any three of the four balls falling within a single pocket. Similarly, betting box


60


envisions a four ball game with the bet covering all four of the balls falling within any single pocket. Obviously, the method of this game is equally applicable on games having either fewer or more balls in play, but with a minimum of two balls in play. In a two ball game, the upper layout would be utilized to cover both balls falling within the range of pockets allowed by the type of bet. Thus, if the bet were “straight up” both balls would have to fall within the same pocket. If the bet were “split” then the two balls would have to fall within one or both of the two pockets covered by the bet. Similarly, in a two ball game, betting box


58


would cover “any one of two” and betting box


60


would cover “any two of two”.




In general, in games with “n” balls in play, betting box


58


would cover a bet for “any n−1 of n”, while box


60


would cover bets on “any n of n”. The estimated payment rate for bets on the upper playing field would be as follows, where 4 balls are used in the game:



















Name of Bet




Payment Ratio













4 of 4 straight up




1,666,667/1     







Split 4 of 4




100,000/1   







Any 4 of 4




40,000/1   







Street 4 of 4




20,000/1   







Any 3 of 4




250/1 







Dozens




80/1







High or Low




15/1







Black or Red




15/1







Even or Odd




15/1















In addition, while the preferred embodiment of the invention utilizes a single roulette wheel with a plurality of tracks


38


for each of the balls in play, the method of the invention would work equally as well with a plurality of separate roulette wheels, each wheel having one or more tracks. The excitement in the game is the possibility of betting on a plurality of balls simultaneously, rather than merely on a single ball for each spin of the wheel.




In use, patrons will gather around each of tables


42


,


44


,


46


, and


48


, associated with each of the balls


26


to be utilized in the game. Patrons will then place allowable bets on the upper and/or lower playing fields


54


and


56


on their particular table. Croupiers then will put the four balls


26


into motion, one after another, from the lower most track


38




a


to the upper most track


38




d.


Preferably, the balls are placed into motion in a direction counter that of the rotation of the roulette wheel. As each ball loses momentum, it will spiral and bounce downwardly to finally fall within one of the pockets


22


on disk


12


. The sensors


52


will detect the presence and location of each ball


26


, and display the location on the associated post


50




a,




50




b,




50




c,


and


50




d.






After the simultaneous display of the four numbers, a croupier at each table will designate the appropriate number on the lower playing field


54


, and proceed to remove losing bets and payout winning bets. The process then begins again.




The method for determining the payout ratio for a particular bet in the improved quadroulette game, where either a plurality of balls are simultaneously propelled, or a single ball is propelled in a series of sequential spins, is the basis of a new method for playing a game of chance of the present invention. In order to determine the payout ratio for the upper playing field, it is first necessary to determine the house advantage and cumulative house advantage for the game. The house advantage for any playing field in a game of chance is determined by the proportionate number of possible conclusions in a trial in the game upon which a player's bets are restricted. For example, an American roulette wheel includes two locations on the wheel into which the ball may fall, but upon which a bet is greatly restricted. Thus, on any given spin of a 38 pocket roulette wheel, the house advantage is equal to 2 divided by 38 or 0.0526.




The probability of winning on a bet on any particular number on the roulette wheel must be adjusted to take this house advantage into consideration. Since two of the numbers are greatly restricted in the “betting pool”, the actual probability for the bet must be adjusted to take the house advantage into account. The house advantage of 0.0526 must be factored into the single ball probability to obtain the actual payout to a player, where a house advantage is present.




In the upper playing field of the present invention, a plurality of balls are simultaneously set into play, each of those balls being subject to a house advantage. For this reason, to determine the upper layout payout ratio, the cumulative house advantage for all of the balls must be determined. The cumulative house advantage is equal to the number of unrestricted “bettable” positions divided by the total number of positions on the wheel, this quantity then being multiplied by itself with the exponent equal to the number of balls in the game. In the quadroulette game disclosed herein, the cumulative house advantage would be equal to (36/38)


4


, which is equal to 0.805518681.




If the game is played with a single ball on a roulette wheel, this exponent would be equal to the number of sequential spins of the wheel, rather than the number of balls simultaneously propelled. Similarly, other games of chance would substitute the number of “trials” for the exponent in this equation.




The next step in determining the payout ratio for a winning bet includes the step of determining the single ball bet probability for a particular bet. As noted above, the single ball bet probability is equal to the total number of spaces which encompass the bet divided by the total number of spaces available on the wheel. Thus, if the bet is for a single number on a conventional American roulette wheel, the single ball bet probability would be equal 1/38. If the bet is for “dozens” the single ball probability would be 12/38.




The single ball bet probability is then multiplied times itself with the exponent equal to the number of balls in the game, in order to produce a multiple ball bet probability. A payout variable is then determined by inverting the multiple ball bet probability to form a fraction where the variable is equal to 1 divided by the multiple ball bet probability. This payout variable is then multiplied by the cumulative house advantage to form a product which is the numerator of the payout ratio. The denominator of the payout ratio is 1.




In the example of a bet on “dozens”, the payout ratio would be determined as follows. First, the single ball bet probability is equal to (12/38)


4


which equals 0.009945. When inverted, this results in a payout variable of 100.55634. As noted above, the cumulative house advantage for the American style roulette wheel is equal to 0.805518681. Multiplying the cumulative house advantage times the payout variable results in a product of 81, which rounds to a payout ratio of 80/1. Technically, it is more accurate to subtract the one dollar bet from the variable before multiplying it by the cumulative house advantage. Thus, the more accurate payout ratio for a “dozens” bet would be (100.5563271−1)×0.805518681=80. Thus, if all four balls in the upper field are located in the particular 12 locations forming the “dozens” bet, the player would win a payout ratio of 80/1.




Obviously, this method could be used with other games of chance having different house advantages and different probabilities of winning, so long as the game of chance includes a plurality of gaming trials, with each trial including a plurality of possible conclusions.




Whereas the invention has been shown and described in connection with the preferred embodiment thereof, many modifications, substitutions and additions may be made which are within the intended broad scope of the appended claims.
