PROBLEM TO BE SOLVED: To provide a pinball game machine having new game property.SOLUTION: A pinball game machine is provided on a second big winning hole 22 with a continuation region where it is determined that a next unit game is started if a game ball enters or passes the hole, and a provability change determination region where it is determined to shift to a probability-changed mode in a normal game after termination of a special game if a game ball enters or passes there. As the opening time of the second big winning hole 22, different opening time may be defined according to the type of big win patterns showing that a determination result is a win. A provability-changed determination region is activated in a specific unit game in a special game, or it is shifted to a mode where a game ball easily enters or passes the provability-changed determination region when compared with a unit game other than a specific unit game.SELECTED DRAWING: Figure 1 |
