In each round one of the players takes the role of the Hall Monitor his aim will be to catch each other penguin. The others, however, will try to run through several doors, thus gaining fish on their way. When either the Hall Monitor has caught each other penguin once or any of the others have gone through all of the doors that have fish on them, the round is over. Each player will take the role of the Hall Monitor once and at the end of the game the winner will be the one with the most points on their fish cards.
