PROBLEM TO BE SOLVED: To enable the manufacturing cost of a mechanism board to be reduced and the board box to be effectively equipped on a part lower than the opening window of the mechanism board. SOLUTION: A prize winning ball collecting passage 32 (32b-32c, etc.), an out ball discharge passage 33 communicating with the prize ball outlet of an out port of a game board, a prize ball guide part communicating with the prize ball outlet of an upper ball tray, and a surplus ball passage 34 communicating with the surplus ball outlet of a lower ball tray are formed in front of a mechanism board of a Pachinko machine, i.e., a space part under a prize ball collecting space to the same side. A prize ball supply device 28 and a prize ball discharge chute 29 are equipped in the rear side of the mechanism board 20. A prize ball guide passage 51 communicating with the prize ball guide part and a surplus ball guide part 52 communicating with the surplus ball guide passage are partitioned and prize balls supplied to the prize ball discharge chute 29 are preferentially guided to the prize ball guide part 51 so the prize balls overflowed from the prize ball guide passage 51 are guided to the surplus ball passage from the surplus ball guide passage 52.
