<p>PROBLEM TO BE SOLVED: To provide a game machine which hardly causes the problem in progress of a game.SOLUTION: A pachinko game machine has an upper big winning port and a lower big winning port, and executes a round game in which the upper big winning port is opened and a round game in which the lower big winning port is opened, in a big winning game state. On the basis of the fact that a game ball entering the lower big winning port has passed a probability variable area in the round game in which the lower big winning port is opened, the state is controlled to a probability variable state. In the vicinity of the probability variable area, a probability variable area cover is provided which changes to a permissible position in which the game ball can pass through the probability variable area and a regulation position in which the game ball cannot pass through the probability variable area. Here, when the number of the game ball entering the lower big winning port and the number of discharged game ball are not matched in the round game in which the lower big winning port is opened, abnormality-time operation is executed which drives the probability variable area cover to dissolve jamming with balls.</p> |
