The rest with the ball line up behind the attacker.
Number 1 with the ball throws to the playmaker, who gives a set up and the attacker tries to score.
The sham is going to try to pass and catch the ball, if he succeeds, the attacker is "dead" and has to take over the place of the sham who may now join the line.
If the attacker scores he will get the ball and join the back of the line.
This continues until there is only 1 attacker left, if he scores again, he or she is the winner.
