PROBLEM TO BE SOLVED: To improve players' interests by applying a newly added value to the game balls discharged outside the playing area. SOLUTION: The game machine is provided with a game board 14 which has a playing area where the game balls roll and pass through a prescribed area to offer prize balls while passage ports 55a and 55b are disposed to guide some of the game balls to a game board rear unit 300 as a non-playing area having a game ball storage part 304 for storing the game balls and calculates the rate of put-out balls as the ratio of the number of balls put out as prize balls to the number of game balls fed into the playing area for each prescribed period. A control is made to express the rate of put-out balls calculated with the game balls stored in the game ball storage part 304, thereby applying a newly added value to the game balls guided to the non-playing area.
