A. -He must be across the halfway line, in his opponents' half of the field (i.e., in the half of the field with the goal which his team is attacking).
-He cannot be in an OSP in his own defending half, even if ahead of all of the opponent's defenders. So, if the opponent's defenders decide to push up over the midline, an attacker can station himself behind them as long as he stays in his own defending half.
-He is closer to his opponents' goal line than the second-last defender (note: if he is even with the second-last defender, he is onside).
-He is onside as long as there are two or more defenders between him and the goal (i.e., even with him or ahead of him).
-He is ahead of the ball.
-The ball is always considered to be onside, so an attacker can play a ball laterally (called a "square pass") or hook it back to another incoming attacker who is even with the ball when it is passed, even if they both are ahead of all the defenders - even the keeper. This occurs often in games, especially at the older age groups when keepers become more daring.
-He is not receiving the ball directly from a goal kick, a corner kick or a throw-in.
-An attacker can be ahead of everyone on the field on a throw-in, a goal kick or a corner kick, and legally receive the ball and score.
-His team has possession of the ball, so that the ball is being played or touched by one of his teammates.
-Normally, you cannot be called for offside if the ball is in the possession of, and being played by, the opposing team. However, where the ball simply ricochets off the keeper or the 2LD, they are not considered to have played the ball, so an attacker can be called for offside if he receives the ball from such a ricochet.

B. player must wear a jersey or shirt, shorts, stockings, shinguards and footwear (i.e., shoes). Goalkeepers must wear colors that distinguish them from other players and the officials.

C. faces the field of play (and normally also faces the direction in which he is going to throw the ball);
has part of each foot either on the touch line or on the ground outside the touch line (that is, the thrower's feet may not be entirely inside the touch line);
uses both hands (many referees interpret this to mean "with equal force")
delivers the ball from behind and over his head.
