This happens at the start of the game, halftime and after a goal has been scored. A forward player standing near the center line kicks the ball to a fellow player. After the ball makes one complete revolution the game is officially started. The kicker may not touch the ball until it has been kicked by another player. After the ball wholly crossed the sideline or goal line it is out of play.
Any ball striking a referee, goal post, corner post and remaining on the proper field is in play.
A goal is scored when the ball wholly 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. While going toward an opponent's goal the offensive team may not have a player ahead of the ball unless there are two defending players present. The exception to this statement is when the player is 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 offsides infraction depending upon whether the offending player is seeking an unfair advantage.
