One person is chose to be "it", they are then blindfolded. The other players then put on bells and try to tag the blindfolded player. "It" must try to evade being tagged. When a player tags "it", they get a point. The first player to get to 10 points is the winner. The player with the least points, becomes the new "it". Once everyone has had a turn at being blindfolded, the player who was "it" for the longest time (during a turn) is the winner
