Abstract

A game of chance is played on a gaming machine controlled by a processor in response to a wager. The game includes an array of locations displayed on a video display and individually selectable by a player and the processor. The player and the processor make alternating selections of unoccupied ones of the locations in the array for placement of respective first and second symbol types. The probability of using a winning strategy for the selections by the processor increases with successive ones of the selections by the processor so that the processor appears to become more intelligent as the game progresses. A payout is awarded to the player based on an outcome of the game.

Claims (17)

1. A method of conducting a game of chance on a gaming machine controlled by a processor, the method comprising:

receiving a wager;

displaying an array of locations individually selectable by a player and the processor;

receiving alternating selections by the player and the processor of unoccupied ones of the locations in the array for placement of respective first and second symbol types, the receiving selections by the processor includes: (a) determining, via the processor, a best location of unoccupied ones in the array for placing the second symbol type, (b) applying a predetermined weighted probability to determine whether the second symbol type should be placed in the best location of the unoccupied ones, (c) if, after applying the weighted probability, multiple unoccupied ones of the locations are available to receive the second symbol type, applying, via the processor, a random determination as to which of the multiple unoccupied ones of locations to place the second symbol type, the weighted probability varying with successive ones of the selections by the processor; and

awarding a payout based on an outcome of the game.

2. The method of claim 1 , wherein the weighted probability increases the probability of a winning outcome for the processor with successive ones of the selections by the processor.

3. The method of claim 2 , wherein the weighted probability increases the probability of a winning outcome by about 10 percent with each successive selection by the processor.

4. The method of claim 1 , wherein displaying the array of locations includes displaying the array of locations on a video display.

5. The method of claim 1 , wherein awarding a payout includes awarding a first payout for a win by the player, a second payout for a win by the processor, and a third payout for a draw.

6. A game of chance for a gaming machine controlled by a processor in response to a wager, the game comprising:

an array of locations individually selectable by a player and the processor;

means for receiving alternating selections by the player and the processor of unoccupied ones of the locations in the array for placement of respective first and second symbol types, the receiving selections by the processor includes: (a) determining, via the processor, a best location of unoccupied ones in the array for placing the second symbol type, (b) applying a predetermined weighted probability to determine whether the second symbol type should be placed in the best location of the unoccupied ones, (c) if, after applying the weighted probability, multiple unoccupied ones of the locations are available to receive the second symbol type, applying, via the processor, a random determination as to which of the multiple unoccupied ones of locations to place the second symbol type, the weighted probability varying with successive ones of the selections by the processor; and,

means for awarding a payout based on an outcome of the game.

7. The game of claim 6 , wherein the weighted probability increases the probability of a winning outcome by the processor increases with successive ones of the selections by the processor.

8. The game of claim 7 , wherein the weighted probability increases the probability of a winning outcome by the processor increases by about 10 percent with each successive selection by the processor.

9. The game of claim 6 , wherein the array of locations is displayed on a video display.

10. The game of claim 6 , wherein the means for awarding a payout includes means for awarding a first payout for a win by the player, a second payout for a win by the processor, and a third payout for a draw.
