<P>PROBLEM TO BE SOLVED: To provide a pinball gaming machine capable of sufficiently exerting an amusement improving effect by a combination of so-called "definite-number probability variation" function and "sudden probability variation" function. <P>SOLUTION: The pinball gaming machine is configured so that when a symbol has a jackpot pattern, a jackpot state is generated to open a big winning means according to a predetermined opening pattern, and when a predetermined start condition is established, a high-probability state is generated until the symbol variation frequency reaches a specific frequency after generation of the jackpot state. In the pinball gaming machine, when the start condition is established during the high-probability state, the time of termination of a specific game state is postponed until the subsequent symbol variation frequency becomes the specific frequency, and when a specific start condition of the start conditions is established, a specific opening pattern A in which a game ball can hardly win a prize is selected as the opening pattern of the jackpot state. When the specific start condition is established during the specific game state, a specific performance is executed, the specific performance indicating that the time of termination of the specific game state is postponed to the time of termination of the specific game state based on the assumption that it is not postponed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
