Gather all players into a circle, and tell them to learn the names of the players around them. The first player goes into the middle of the circle, and is the shooter. That person points to a person in the circle, yelling "BANG". The person being shot ducks, and the two people on the ends of the ducking person need to shoot each other by yelling the other person's name correctly as fast as possible. The first one to say the name wins the duel. The person who died can either be eliminated from the game, or be the new person in the middle if you don't want players to be eliminated.
