Claims39
A method of operating a gaming device including at least one memory device which stores a plurality of instructions, said method comprising:
- (a) causing at least one processor to execute the plurality of instructions to provide, for a single play of a game, a first attempt for obtaining any one of a group of awards, the first attempt having a first probability of obtaining one of the awards, said first probability being greater than zero;
- (b) causing at least one display device to display the first attempt;
- (c) after displaying the first attempt, for the single play of the game, causing the at least one processor to execute the plurality of instructions to provide a second attempt for obtaining any of the remaining awards from the group:
- (i) the second attempt having the first probability of obtaining one of the awards if the first attempt does not successfully obtain one of the awards, and
- (ii) the second attempt having a second probability of obtaining one of the awards if the first attempt successfully obtains one of the awards, said second probability of obtaining one of the awards being different than the first probability of obtaining one of the awards;
- and
- (d) causing the at least one display device to display the second attempt.
A method of operating a gaming device including at least one memory device which stores a plurality of instructions, said method comprising:
- (a) causing at least one processor to execute the plurality of instructions to provide, for a single play of a game, a first attempt for obtaining an award selected from a group of X number of awards, X being greater than two, said first attempt having a probability of success greater than zero;
- (b) causing at least one display device to display the first attempt;
- (c) after displaying the first attempt, for the single play of the game, causing the at least one processor to execute the plurality of instructions to provide a second attempt at obtaining a second one of the awards, the second attempt having a probability of success equal to ((X−1)/X) if the first attempt is successful at obtaining one of the awards;
- (d) causing the at least one display device to display the second attempt;
- (e) causing the at least one processor to execute the plurality of instructions to provide, for the single play of the game, a third attempt at obtaining a third one of the awards, the third attempt having a probability of success equal to ((X−2)/X) if the first and second attempts are each successful at obtaining one of the awards;
- and
- (f) causing the at least one display device to display the third attempt.
A method of operating a gaming device including at least one memory device which stores a plurality of instructions, said method comprising:
- (a) for a plurality of attempts at obtaining a plurality of randomly generated awards for a single play of a game,
- (b) causing at least one processor to execute the plurality of instructions to provide a plurality of successive probabilities of success at obtaining the randomly generated awards, the probabilities being provided according to a function of (x−n)/x, x being a total number of awards and n being a number of prior successful outcomes obtained and a first of the probabilities of success being greater than zero;
- and
- (b) causing at least one display device to display each of the attempts.
