Summary:PROBLEM TO BE SOLVED: To provide a synthetic resin game board in which the bouncing amount of a game ball at the time of colliding against a nail is sufficiently increased. SOLUTION: An opening bottom hole 36 is installed on a game surface 26 in a way that it penetrates a platform 20. The bottom hole 36 is made in a shape with steps provided with: a large diameter section 44 composed of an opening on the game surface 26 side with larger inner diameter than the outer diameter of a body section 38 of a nail 30; and a small diameter section 46 composed of the section except for the opening on the game surface 26 side with smaller inner diameter than the outer diameter of the body section 38 of the nail 30. The nail 30 is fixed on the platform 20 by press-fitting it into the small diameter section 46 in a state that it is not in contact with the inner periphery of the large diameter section 44 of the bottom hole 36.
