A lump of clay is held in between the hands of the 'Thumb War Players'. Thumb War is a game played by two players in which the thumbs are used to simulate fighting. The object of the game is to pin the opponent's thumb, often to a count of three. The players face each other, and each holds out their left hand or right hand in a "thumbs up", they link hands such that each player's fingers curl around the other player's fingers. Players may not use any of the fingers except the thumb to pin down their opponent's thumb.
