A partner game where you stand back to back and face to face.
Players stand in pairs, except one player who is "it". When "it" calls "Back to back!" the players must back up to a partner. When "it" calls "Face to Face!", these partners must face each other and shake hands. On the next call "Back to back!" and each time thereafter, all players must change partners. "It" tries to get a partner during the change. The player left out becomes "it".
