PROBLEM TO BE SOLVED: To provide a pinball game machine adapted to further enhance presentation performance by busy circumference of a prize winning passage for a game ball captured by a wing member and to be simplified as much as possible. SOLUTION: In a Pachinko game machine, a center Yakumono (prize winning port) includes a game ball-guiding passage extended on both sides of a big hit lottery portion 5 (e.g. numeral 4), and piston-shaped members P1-P4 positioned on both sides of the big-hit lottery portion 5 and disposed so as to be alternately protruded from and retracted into the game ball-guiding passage at a certain cycle. Threrefore, the circumference of the game ball-guiding passage as a prize winning passage for the game ball captured by the center Yakumono is busied by alternately protruding and retracting the piston-shaped members P1-P4 at a certain cycle to appeal to the player's eye, and the presentation performance is further enhanced.
