PROBLEM TO BE SOLVED: To provide a game machine capable of preventing erroneous detection of ball detection means. SOLUTION: In a back unit box 24, a left ball path 25 for discharging and guiding Pachinko balls B which enter upper and lower left normal winning ports is formed. At an attaching part 27b formed at the lower end part of a first left vertical path 27 communicating with the upper left normal winning port in the left ball path 25, a left normal winning sensor 30 is disposed matching a passing hole 30b with the path 27. On a rear wall 25b in the first left vertical path 27, a left projection 32 projecting inwards from an inner edge in the passing hole 30b of the left normal winning sensor 30, projects at a position above the attaching part 27b. That is, the Pachinko balls B which enter the upper left normal winning port and flow down the first left vertical path 27 hit the left projection 32 and then pass through the passing hole 30b of the left normal wining sensor 30.
