To provide a pinball game machine that allows a player to reduce symbol variation time, and increases the interest of a player without excessively increasing gambling spirit.

When a game ball enters a start pocket, reserve information is stored, it is determined in advance whether the stored reserve information is specific reserve information, and symbol variation is performed on the basis of the stored reserve information. Before starting the symbol variation, variation time is decided in advance, and after the variation time passes, the symbol is stopped. Performance is executed along with symbol variation. Operation of an operation part is enabled during the symbol variation on condition that the stored reserve information contains specific reserve information. When the operation part is operated, a symbol is stopped before the variation time passes. The reduced time is calculated by subtracting actual variation time from the predetermined variation time. The reduced time is added to the symbol variation time for the specific reserve information.
