To achieve a Pachinko machine preventing a player from losing since the player does not know immediate occurrence of a jackpot after completion of a probability variable game state.

In a setting where a probability variable game state is completed when the number of variation times reaches 70, when the number of variation times reaches 67 and the remaining number of variation times N is 3, a special symbol retention number U reaches an upper-limit value, namely 4, and the fourth retention becomes a jackpot (a). After that, when variation display based on retention is performed for three times and the remaining number of variation times N reaches 0, the probability variable game state is completed and a probability variable performance is also completed (d). Then, in execution of variation display based on the first retention, the probability variable performance is extended (e). In the variation display, a jackpot symbol is determined and displayed and a jackpot occurs. In this manner, by extending the probability variable performance, completion of the probability variable game state cannot be recognized easily.
