Team red starts as the attacking team and want to score on the big goal.
Team blue is the defending team and want to conquer the ball and score in the goall on the side.
One person, from the defenders, starts with the ball and plays the ball back to someone on the attacking team. That defender runs onto the pawn and runs a tackle back.
Team white is waiting on the other side and hits ready to start when the other side has scored or the ball is out.
Then the defending team stands to the side and no longer participate
The attackers then become the defenders and go on the other side to defend the new team. it keeps going like this.
