Two teams square off in 4v4 or 5v5 games. No goalies, no offsides, and pretty much no rules. Score as many goals as you can while steamrolling the competition.
One person is designated the "shark" and everyone else "minnows". The minnows attempt to cross the field without getting knocked over. If they get knocked over they join the shark next round. So much fun.
One player from each team is the football. Win by getting your team's football into the other team's end zone while keeping the other team's football out of yours.
Two teams compete for CTF glory. The mission is to capture the other teams flag and return it to your side of the arena without getting knocked over.
(We come prepared to play all of these games at our rentals.)
