All you need for a fun and competitive (if you want) game of 2 vs 2. Play on grass, sand or indoors. A player starts a point by serving the ball down onto the Spikeball net so it ricochets up at his opponents. The returning team has up to 3 hits between them (think bump, set, spike) to return the ball back onto the net. The rally continues until a team can’t return the ball onto the net within their three touches. Set includes Spikeball set, 3 Spikeball balls, drawstring storage bag, and rule book.
