There are two players, and each one gets 5 cards with values from 1 to 5. Then the players reveal one of the cards in their hand simultaneously in rounds. If both are identical, or if one is a "1" and the other a "5", both cards remain on the desk. Otherwise the player who played the higher card takes it back to her hand, whereas the lower card must remain on the desk. The first player unable to put down a card loses.
