The standard BoxxyBall game is designed for 1 v 1 or 2 v 2.
However, more players can play on a standard court, e.g., 3 v 3 works well when younger players are involved.
BoxxyBall Xtra is designed for more players, e.g, 3 v 3, 4 v 4, 5 v 5 or even 6 v 6. This version of the game uses a larger net and is played on a regular volleyball court.
