PROBLEM TO BE SOLVED: To provide a ball game device in which the space of a play field can be more efficiently used and a player can fairly aim at all prize winning holes by rotating the prize winning holes and the player can enjoy a game more interestingly in the game device that balls are dropped along a vertical surface or rolled along an inclined surface, because the prize winning holes are not fixed to the play field and arranged along the outer periphery of a rotating board disposed on the center of the play field so that the prize winning holes can be arranged more on a circumference than those on a fixed straight line. SOLUTION: The ball game machine comprises the play field provided on the prescribed vertical surface or the inclined surface to drop or roll the balls, the rotating board having U-shaped grooves on an outer periphery to which the ball are fitted, a detecting means for detecting the positions of the balls fitted to the U-shaped grooves provided in the rotating board, a means for driving a present conveyor as a result of the positions of the balls and a means for putting out medals as a result of the positions of the balls.
