Below are the official rules of Spikeball, used for tournament play in USA Spikeball and most leagues across the country. Two teams square off consisting of 2 players each, lining up across the net from one another. Play starts with one team serving, hit behind the outside boundary line into the spikeball net towards the opposing team. After the serve, both teams can move around as they please. A point is scored once a team cannot successfully return a serve or hit into the net within the 3 touches allowed.
Unofficially, there are plenty of variations to the rules of spikeball that are played as well, some more popular than others. Below is a simple modification that we really enjoy playing that seems to simplify the game a bit, reduce the athleticism needed to compete while keeping the game fun and interesting and still very competitive. The simple difference is that instead of players being able to freely roam around the entire net, the field is split into 2 halves, with one team on each side. This eliminates judgement calls on player interference penalties or reserves, reduces the risk of players running into each other and while still active, is quite a bit less strenuous as far as players jumping and diving around. All other rules still apply, but this one rule completely changes the game, some say for the better.
