PROBLEM TO BE SOLVED: To provide a game machine which can exchange a certificate component and can find fraudulence when the certificate component is fraudulently exchanged.SOLUTION: An engagement part 440 includes an engagement pin 450 which engages with the certificate component 400 so as to make the certificate component 400 impossible to be detached from a game board 30 and is separately provided from the certificate component 400. The engagement pin 450 has a cut part 471 enabling the certificate component 400 to be detached from the game board 30 by being broken, so that the certificate component 400 is impossible to be detached from the game board 30 without breaking the engagement pin 450 of the engagement part 440, when the certificate component 400 is engaged with an attached part 30b of the game board 30 by the engagement part 440. Thus, the integration inseparability of the certificate component 400 and the game board 30 can be secured, fraudulent exchange of the certificate component 400 can be reduced, and it can be guessed that the engagement pin is broken by a person who is not a rightful worker by seeing trace of breaking the cut part 471 of the engagement pin 450 and loss of the engagement pin 450. |
