PROBLEM TO BE SOLVED: To provide a game machine avoiding an error in detection of a game ball filled-up state. SOLUTION: A Pachinko game machine 10 has: a ball path 70 which makes Pachinko balls flow down on to a lower tray 44 as exceeding the storage capacity of an upper tray 42; an expanding part 77 which expands the ball path 70 sideways to get the Pachinko balls retained as exceeding the storage capacity of the lower tray 44; and a detection lever 94 and a photo sensor 110 which are disposed on a sidewall making up the expanding part 77 and pushed with the Pachinko balls retained to move to a filled-up state detection position. The Pachinko game machine 10 further has a putout control board 88 which stops the putting out of the Pachinko balls from a putout device 62 based on detection information of the photo sensor 110. With the ball path 70 not yet filled up, since the Pachinko balls flow down in the expanding part 77 in a shortest distance, they hardly come into contact with the wall of the expanding part 77, which keeps the detection lever 94 from turning, thereby preventing an error in detection of the filled-up state.
