PROBLEM TO BE SOLVED: To provide a board surface structure of a game machine, securing the degree of freedom in design in a playfield even when various devices such as a presentation display device are made large-sized. SOLUTION: A playfield 110 surrounded by an outer rail 103, an ornament member 104, a rail member 151, and an inner rail 105 is formed on a game surface 102. A guide passage 106 is formed along the inner rail 105 on the left of the playfield 110. A rail member 151 constituting the base of a second lower area 110d located at the lower right of the playfield 110 has a smaller angle of inclination than the inner rail 105 constituting the base of a first lower area 110c located at the lower left of the playfield 110. Thus, a lower-right area of the playfield 110 is secured widely to form various ball entering ports in the second lower area 110d. COPYRIGHT: (C)2011,JPO&INPIT
