<P>PROBLEM TO BE SOLVED: To provide a pinball game machine, capable of fully exhibiting 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 gets into a jackpot mode, 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. When the start condition is established during the high-probability state, the end time 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 end time of the specific game state is postponed to the end time of the specific game state based on the assumption that it is not postponed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
