PROBLEM TO BE SOLVED: To achieve a game machine in which shift to a high probability state is established by a game ball reaching a specific area, by one big winning port.SOLUTION: In a big winning for imparting the high probability state after the big winning, when the big winning port is operated in a probability variable form, a game ball that enters the big winning port reaches a probability variable port through an opened shutter. In a big winning for not imparting the high probability state after the big winning, the big winning port is operated in a probability non-variable form, and the game ball that enters the big winning port is blocked by a closed shutter and cannot reach the probability variable port. Thus, whether or not to impart the high probability state after the big winning can be achieved by one big winning port. Also, since an opening/closing form of the big winning port is changed according to a symbol, it is possible to make a probability of becoming the high probability state be different according to whether it is a first symbol or a second symbol. |
