PROBLEM TO BE SOLVED: To provide a pachinko machine which can distinguish certainly prize balls from dispensed balls and can count the number of delivered balls. SOLUTION: This pachinko machine is provided with a ball-delivery unit equipped with a sprocket driven by a pulse motor. On the downstream side of the ball-delivery unit, a flow-route changeover unit is arranged, which bifurcates a guide conduit into a prize-ball flow route and a rental-ball flow route, and at the bifurcation point, a flow-route changeover valve is provided to guide balls into whether the prize-ball flow route or the dispensed ball flow route. A prize-ball detector and a dispensed ball detector 62 are arranged in the prize-ball flow route and the dispensed ball flow route respectively. Detection signals from said prize-ball detector and detection signals from the dispensed ball detector are transmitted to a delivery controller as confirmation signals respectively, and the flow-route changeover valve is restored after a certain time from the rental-ball final detection.
