PROBLEM TO BE SOLVED: To provide a game machine which can prevent the fraudulence by immediately discovering (electrically detecting) the fraudulence attempted onto game nails or prize devices within a playing area with a piano wire or the like, for example, through a hole bored in a glass frame 13 of the game machine. SOLUTION: The game machine is provided with a game board 10 in which game nails 40 are placed on the front of a base material 10a, a body frame 11 where a housing part 11a for housing the game board is formed and a glass frame 13 which is openably pivoted on the body frame to hold a glass plate 14 making the game board visually recognizable. An electroconductive layer 10b in continuity with at least the game nails is formed on the front of the base material while the glass frame 13 is formed out of an electroconductive member and a fraudulence detection means (display controller 110) is installed being electrically connected to the elecltroconductive layer and the glass frame 13 to detect the fraudulence from the electrical continuity of the glass frame 13 and the electroconductive layer occurring through an electroconductive foreign matter.
