All players are sent a suitcase containing 100 million yen and are told to protect it from their assigned opponent. No dealers are used in this game as players are contacted by the Liar Game Office via cards. Once the player opens the suitcase with the 100 million yen inside, it is taken as a sign that they agree to participate in the tournament.
Players are assigned opponents, and they must do whatever they can to steal as much of the 100 million yen from their opponent as they can. As money is stolen the players are updated with the results. The game lasts for one month, and players are told the exact time the game ends a few days prior to the final day.
