PROBLEM TO BE SOLVED: To provide a game board of a pachinko machine with improved game properties. SOLUTION: The game board is structured so that a game ball rolling/moving on a rear stage part 110 in a center ornament 100 passes a center inclined part 112 or either left or right inclined part 113 or 114 and falls down from the rear stage part 110 after that. A center stage part 140 comprises ball passages 141 and 142 through which the game ball having fallen from the center inclined part 112 can roll/move, a pit 144 disposed at the distal ends of the ball passages 141 and 142 for the game ball reaching the distal ends of the ball passages 141 and 142 to fall toward a first front stage part 120, and a tapered part formed in an opening on the ball passage side in the pit 144. The game ball reaching the distal ends of the ball passages 141 and 142 is made to fall from the pit 144 while rotating after rolling/moving along the tapered part. COPYRIGHT: (C)2006,JPO&NCIPI
