PROBLEM TO BE SOLVED: To provide a game board of a pachinko game machine which can improve the playing performance. SOLUTION: In the game board of the pachinko game machine, when balls are shot intensely onto a playing area 3 from a ball shooting path 2, the balls bump against a center decoration 14 with the clearance 41 of a ball inlet part 40 that is so formed as to enable only one ball to pass but none of two balls aligned longitudinally to raise the possibility of being bounced back to a gage area 5. On the other hand, the balls bounced back to the gage area 5 are caused to flow down on the gage area 5 with the clearance 42 between a game nail 7 provided near the ball inlet part 40 that is so formed to let only one ball pass but none of the two balls aligned longitudinally and a guide rail 4.
