A game where you are blindfolded and try to tag the other players.
Blindfold one player and spin them around 3 times. The blindfolded player tries to tag one of the other players, who may crouch low, sneak up behind the "blindman" and yell "Boo", or stand still and keep very quiet. Eventually though, someone will get careless and be tagged. That player is then blindfolded for the next game.
