PROBLEM TO BE SOLVED: To provide a game machine which can restrain inserted game balls from being inappropriately detected. SOLUTION: The game machine is structured so as to detect the passage of game balls by upstream sensors 553 and 2553 and downstream sensors 554 and 2554 arranged in the region in a pathway where the distribution direction of the game balls change. Even if a plurality of game balls flow in a row (in succession), the game machine can form a condition where game balls are not detected by both of the upstream sensors 553 and 2553 and the downstream sensors 554 and 2554. As a result, the game machine can unerringly detect the inserted game balls by restraining such an appropriate detection as the mistaking of the game balls flowing down in a row for one game ball.
