Abstract: This game system enables the entry of a new game terminal into a currently operating multiplayer game system, or the isolation of a specific game terminal from a currently operating multiplayer game system. Each game terminal includes a master/slave setting section which detects whether or not data is being transferred over data transfer lines when that game terminal starts up, and either sets itself to be the master machine if transfer data is not present, or sets itself to be a slave machine if transfer data is already present. The game system also includes an entry acceptance signal transfer section wherein the master machine transfers an entry acceptance signal between game terminals for accepting entries into the game system.
