About Sumo Volleyball

This project is a fan-made recreation of the classic Sumo Volleyball originally created by Shizmoo Games. Our goal is to bring back the original gameplay experience as faithfully as possible — the physics, the feel, the fun — for a new generation of players. We do not claim ownership of the original game's intellectual property.

We are not affiliated with the team at sumovolley.com who are developing a mobile version of Sumo Volleyball. We respect their work, but we believe that Sumo Volleyball as it was meant to be played belongs on a keyboard — the precise, responsive controls that made the original so addictive simply can't be replicated on a touchscreen.

History

Sumo Volleyball was created by Shizmoo Games, a small studio founded by brothers Dan Goldstein and Joshua Goldstein. Shizmoo first gained recognition with Kung-Fu Chess, a real-time chess variant that won the Audience Choice Award at the 2002 Independent Games Festival. Sumo Volleyball followed as the studio's second hit — a deceptively simple 1v1 and 2v2 volleyball game featuring sumo wrestlers that became beloved for its tight physics and fierce competitive play.

Early 2000s
Shizmoo Games launches on shizmoo.com with Kung-Fu Chess and Sumo Volleyball. Both games use a belt-based rating system (colored belts from green to black) to rank competitive players. The games run as ActiveX/browser-based multiplayer — pretty much IE-only at the time.
2005
Sumo Volleyball and a simplified version of Kung-Fu Chess are integrated into the ICQ instant messaging program, exposing millions of users to the game. Sumo Volleyball becomes the more widely played of the two, building a loyal community of competitive players.
~2007
The game is picked up by MTV Arcade (MTV's online gaming portal). Shizmoo.com begins redirecting to Sumo Volleyball on MTV.com. This version reaches an even wider audience but with a different look and feel.
2008
Shizmoo.com goes offline permanently. The original community of dedicated players scatters, though many continue to remember and discuss the game for years to come.
2025
This fan recreation launches at sumovolley.org, aiming to recapture the original keyboard-driven gameplay with modern web technology.
