Ballz is a two-player 3D action fighting game for the Sega Mega Drive/Genesis, the Super NES (SNES) and the 3DO. It was developed by PF Magic and published by Accolade in 1994. The 3DO version was released as a director's cut in 1995. Ballz offered three difficulty levels over a total of 21 matches. Its distinguishing quality was that each of the characters were composed completely of balls, with a pseudo-3D look. Although the game was not a tremendous success, PF Magic reused its graphics technology in a successful line of virtual pet titles, Petz, Dogz, Catz and Oddballz.

The opening PF Magic developed for the game stated "To be the champion, you gotta have Ballz!". Due to its racy double-entendre ("balls" may be used as a slang term for testicles), Nintendo demanded the wording be changed for the SNES version. The SNES version of the game states "...you gotta play Ballz", while the Sega version uses the original intro. The game was also notably bizarre for its lineup of fighters, which included a farting monkey, a jumping clown, a sumo wrestler, a caveman, a bodybuilder, a ballerina, a rhinoceros and a "superhero".
