PROBLEM TO BE SOLVED: To prevent an increase in winning of starter prizes discarded as invalid as much as possible when the occurrence frequency of winning starter prizes changes higher. SOLUTION: In the game machine, the variable display of a variable display device 24 is started by responding to the winning of a starter prize with a shot ball entering a starter slot 5 shiftable to a position of making shot balls easier to win or a position of making them harder to win. When a special jackpot pattern is presented as the result of the stoppage, thereafter, the probability of winning the jackpot is heightened while the game is shifted to a variable probability state that an openable wing piece 102 provided at the starter slot 5 is opened to heighten the probability of winning starter prizes. The variable display time of the variable display device 24 is shortened when the start memory counts reach 4 as given by a start memory LED 33 under the normal state other than the variable probability state, whereas the variable display control time is shortened under the variable probability state when the start memory counts exceed 2.
