GAME MACHINE

PROBLEM TO BE SOLVED: To provide a game machine which reduces the burden at the time of designing the game machine and with which a player can play a game without loss. SOLUTION: In the game machine whether of not a ball is left in a role object variable prize winning unit is confirmed based on the detecting result of a role object prize winning detecting switch 33a3 and a non V prize winning detecting switch 223, an opening and closing member is inhibited to change into an opening state in the case that a ball is left in the role object variable prize winning unit. Consequently, a designed value set in advance can be made be approximated to a practical measured value when doing a game practically in an expected value in which the ball is sorted to a V guiding unit because a new ball can be prevented from entering the role object variable prize winning unit. As a result, the burden at the time of designing can be reduced without needing a complicated design. Further, jackpots can be surely detected and the player is prevented from having loss because the detection of the ball by a V prize winning detecting switch 33b8 is confirmed while the ball is left within the role object variable prize winning unit.
