Players must stay within the boundaries. Referees Referees are on the field during the game. They check players to determine if they have been tagged. Refs can and will remove players who violate safety rules. Five-person teams play a variation known as center flag.
Teams play against each other in sets, two games per set.
Points are given for flag capture, flag hang, number of opponents tagged and for winning a set. Paintball Sports International, October, 1995. Randy Kamiya, Editor of Paintball Industry Magazine. Sports Illustrated, October 19, 1981.
