Every escape room needs a players' emergency exit. This is not an exit onto the street. The emergency exit allows players to leave the game for any reason. Whether the power went out, they panicked, or nature came calling, players can exit the game.
Anyone utilizing the emergency exit forfeits their place in the game. They have to wait in the lobby for their friends to finish. Then, they sit at a corner of the dinner table, silent, head down, wishing they had not left the room as they hear the tales of glory from their escaped teammates.
Everyone knows that escape games lock players in (anyone who doesn't really needs to read up on
