This is two volleyball games going on at once played by three teams. The two courts are set up in a line with the middle team playing on a side with normal dimensions against the two outer teams at the same time (The court is one and a half times as big as a single volleyball court since the middle area is used for both games.) You might put the better players in the middle; they need to play in both directions.
Almost everyone loved this game. Kids who don’t like any active games didn’t like this game either.
