<P>PROBLEM TO BE SOLVED: To provide a pinball game machine for attaining a novel game by changing processes of a game. <P>SOLUTION: The pinball game machine performs an advantaged jackpot game where a larger amount of game balls is dispensed and probability that an extended opening period is set is higher after termination. The advantaged jackpot game is frequently started in the extended opening period, and can be started in a normal state which is not the extended opening period or a high probability state. When a state is changed from the normal state to a latency state where extended opening is not performed and the probability is high, the advantaged jackpot game is not started unless the extended opening period is entered. <P>COPYRIGHT: (C)2012,JPO&INPIT |
