When a performance button is operated within the operation valid period, the central CPU determines whether or not to execute a probability-variation announcement performance at an execution probability of a probability-variation announcement performance according to the determined variable pattern P3 or P4. When the determination result is Yes, the central CPU rotates a rotating movable body in stages.</p> |
