Spikeball is a popular modified version of 2v2 volleyball created in 1989 by Ewan Sellars and abandoned in the 1990s. From 2008 - present Kankakee Inc. (USA) and Spikeball Europe Sport, Marketing & Entertainment GmbH (Europe) made Spikeball popular. There are multiple ways to play Spikeball. Most games consist of four players, but there are also two- and six-player variants. Differences include where the players line up, infraction penalties, among others. The materials used in Spikeball include a small trampoline-like object with string netting, a small bouncing ball (usually yellow) with a 12-inch circumference, and four players. In standard play, players line up next to each other around the trampoline; in other versions, they line up across from each other. In all versions, the game starts with a serve from one team to another, continues as long as the ball is being hit from players to trampoline, and ends when an infraction occurs between either the players or the ball.
