<p>PROBLEM TO BE SOLVED: To provide a pinball game machine which is novel and allows a game content to be easily understood.SOLUTION: When game balls enter a variable start pocket and jackpot occurs, a jackpot game is played. Even when jackpot occurs in a normal probability state, an opening time of the variable start pocket is not extended after the jackpot game, but when jackpot occurs in a high probability state or when jackpot occurs in an opening time extended state, an opening time of the variable start pocket is extended. It is hard to extend the opening time of the variable start pocket, but once extended, it is relatively easy to maintain the state, so that the game in the opening time extension state can be satisfactory. In addition, it is possible to play a more novel game than ever that even when the opening time is not extended, the game in a high probability state can soon restore an opening time extension state.</p> |
