rules to play roller skating

Points are scored as follows A jammer receives one point for every member of the opposing team he or she passes, every time he or she laps the pack. If a blocker commits a foul on a jam skater, the jam skater will be awarded the point that he or she is attempting to score. If, in the opinion of the referee, there is a deliberate penalty against a jammer to prevent that skater from scoring, and this jam would determine the games outcome, the official may award up to 5 points on the jam. The determining factor would be the score differential at the time of the jam. The injured teams score could not be raised higher than the fouling opponent.
