PROBLEM TO BE SOLVED: To reduce the cost, save an electric power and effectively suppress an irregular game in a game ball rotating movement-distribution device of a pinball game machine having a plurality of rotating bodies related to winning. SOLUTION: This game ball rotating movement-distribution device of the pinball game machine is provided with a plurality of rotating bodies freely rotating in the axial rotation direction, having one end face crossing with the rotation axis direction made to face a game machine front side, receiving sent game balls with a retention part and sending them to a downstream side, wherein a rotating body in the downstream side of the rotating bodies is used as a distribution rotating body for distributing the game balls to a winning route or a failure route according to their rotating positions, and a motor 41 for operatively connectingly actuating the plurality of rotating bodies by a gear mechanism 42 is defined as one for rotating a single gear 44. The number of teeth of at least one gear out of the plurality of gears 48-50 is set to a prime number, and the least common multiple of the numbers of teeth of the gears 48-50 is set large so as to set the period of the rotating position of the rotating body large. This constitution can make it difficult for players to estimate a relation between the rotating positions of the rotating bodies and the distribution timing to the winning passage.
