4 -6 teams of 3. Half on mini line in teams of three other half on goal line. Ball starts from goalie to other team who attacks. 18 yard line is offside for attackers. Defenders start at 6 yard box.
Once score on ball dead rotate. Attacking team on mini side goes off field to goal line and team defending on big net go off field on side of minis. Team on outside just rotate into middle on their respective side.
