A forward player standing near the center line kicks the ball to a fellow player. Opposing players must stay outside the center circle until the ball has been kicked. After the ball is touched the game is officially started. The kicker may not touch the ball again until it has been touched by another player. After the ball completely crosses the sideline or goal line it is out of play.
Any ball striking a referee, goal post, or corner post and remaining on the proper field is in play.
A goal is scored when the ball completely crosses the goal line, between the goal posts and under the cross bar. The winner of the game is determined by the margin of goals scored. A player is not offside when in his own half of the field of play or if the ball was last touched by an opponent. The referee has the right to call or not call the offside infraction depending upon whether in his judgement the offending player gains or is seeking an unfair advantage. When offside is called, the defending team is awarded an indirect free kick from where the infringement occurred.
