PROBLEM TO BE SOLVED: To provide a Pachinko game machine that inhibits a ball from entering a general prize winning opening at upside of a variable prize winning device during an open driving of opening and closing members each of which is driven when a ball is passed through a trigger region, so as to prevent a chance of causing a big win from being lost. SOLUTION: A screening member (a ball inflow-inhibiting member) 17 that is changed over and driven between a screening position where it invades an upside of the general prize winning opening 16 to make inflow of the game ball impossible and a standby position where it retreats to make flow of the ball into the general prize winning opening 16 possible is arranged at a position above the general prize winning opening 16, so as to change over and drive the screening member 17 to the screening position when open driving of the opening and closing members 4a, 4a.
