IMPORTANT - Rule update:

Rule 6 has been updated:

6. Only the defending keeper is allowed in the goal area. Keepers must distribute the ball under arm and below waist height, failure to do so will result in a free kick being awarded 3M from where the ball left the penalty area.
A defending outfield player who enters the penalty area to play the ball or to seek to gain an advantage will have a penalty kick awarded against him. However if the defender plays the ball but his momentum takes him into the area this is not an offence.
An attacking outfield player playing the ball or seeking to gain advantage from entering the goal area will have a free-kick awarded against him which will result in a keeper throw out. However if the attacker plays the ball outside the penalty area but his momentum takes him into the area this is not an offence.
