CONSTITUTION:When it is judged that a coin thrown in is appropriate, game balls and the number of coins are displayed by a ball/coin conversion rate for the credit of the coin. When a start switch is turned on and a game ball sensor confirmed a ball shot ball, the number of game balls is subtracted one by one and the number of the coins is divided by a ball/coin conversion rate, and the result is displayed by cutting off the digit of decimal point and lower. Also, when there is no return ball, a random number is generated, and it is judged which random number region is, and a prize flag is erected. By the detection of a star ball, a variable display is presented based on the judging result of the prize flag, and a prize operation is performed. In this case, by the detection of a safe ball which enters a normal prize port, fluctuating or variable prize device, the number of game balls by a specified discharging rate is added to the displayed number of game balls, and the number of coins in response to the ball/coin conversion rate is displayed. |
