The players each attempt to 'palm off' as many cards as possible on the other players. This is done by offering a card to another player stating at the same time, correctly or incorrectly, what creature is pictured on it. The player who misjudges the other ends up with the card.

The first player who gets four of the same card 'palmed off' on him, or who doesn't have any cards left in his hand when it's his turn to offer a card, loses.
