Instead it relies on running, agility, passing, catching and communication. Its these aspects that make Touch an ideal sport for all, regards of ability or age.
Teams are made up of 14 players with 6 being on the pitch at any one time. Its rolling subs so players can substitute themselves as often as they like during a game. There are three categories of team, either all male, female or mixed (3 male/3 female). Most of the Touch played in Scotland at club level is mixed. The aim of the game is to score touchdowns and prevent the opposition from scoring, each touchdown counts as one point. Each team gets 6 touches after which possession changes, unless an infringement has occurred. After each touch the defence must retreat 5 meters in a straight line onside.
