In typical game play, players attempt to move towards a base through individual control of the ball, such as by dribbling (running with the ball close to their feet), by passing the ball from teammate to teammate and by taking shots at the base. Opposition players may try to regain control of the ball by intercepting a pass or through tackling the opponent who controls the ball. Tackling usually means barging a player on the opposing side. Barging must be done with the shoulder and must not be from directly behind the opponent as to hit their back. You are permitted to tackle even if the opponent is not in possession of the ball.
