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