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 game balls enter a start pocket, reserve information is stored, and special symbol variation is performed on the basis of the reserve information. Before starting the special symbol variation, variation time is decided in advance from among predetermined multiple kinds of variation time. When the variation time passes, the symbol is stopped. As a performance patter for executing the performance along with the symbol variation, a basic performance pattern corresponding to the predetermined multiple kinds of variation time and an auxiliary performance pattern for complementing the shortage are stored. When the operation part is operated during symbol variation, the symbol is stopped before the variation time passes. Reduced time is added to the variation time of a symbol corresponding to any of the reserve information. In accordance with the added variation time, the basic performance pattern and the reserved performance pattern are combined to form a performance pattern.
