Japanese Patent JP2015019764

A

PROBLEM TO BE SOLVED: To provide a game machine in which security against fraudulent acts is improved.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, even when a probability variable area switch detects the game ball when the probability variable area cover is located at the regulation position, probability variable control conditions are not established.
