PROBLEM TO BE SOLVED: To provide a Pachinko game machine preventing a user from acquiring an illegal profit. SOLUTION: The machine includes, as a variation period setting means 30, a first variation period setting means 35 which sets a first special symbol variation period when a game ball passes through a first starting port SW during a normal game and a second special symbol variation period when the game ball enters a variation prize-winning device and passes through a second starting port SW during a short-period game; and a second variation period setting means 36 which sets a second special symbol variation period when the game ball enters the variation prize winning device and passes through a second starting port SW during the normal game. The second variation period setting means 36 sets a sufficiently long period as the variation period of the second special symbol when the game ball enters the variation prize-winning device. Therefore, even when the player puts the game ball into the variation prize winning device by "hitting a game ball aiming at the right side" during the normal game, it is difficult to hit the game ball at the timing of opening and closing of an upper big prize-winning device, so that the user is prevented from acquiring the illegal profit.
