Sumo is a multiplayer physics-based party game for up to 4 players, where players use their wits, special abilities, and spherical physique to wrestle your human or AI opponents over the edge of irrationally hazardous Arenas. You have only one objective - Be the last sphere standing.

Sumo was originally a small-priced product and was a learning project for our team. It did not have commercial interest, and we ceased development on it in 2019. Since it isn't commercially viable, I decided to make the game free for everyone - I'd rather it be a possible bit of entertainment for some if possible!

If you do enjoy, please consider checking out our current title, which has been published and successful and will continue to be our primary development focus in the future.

Fast-Paced Action

Each of Sumo's spherical combatants is deceptively maneuverable -- dashing and jumping to juke attacks and hazards alike. Do your best to snap up Boost Orbs to power up your devastating ability, before your round rivals do.

Unique Arenas

Each Arena in Sumo offers creative ways to send your opponents careening off the edge. But beware, all Arenas continuously collapse, leaving only one player victorious. In Sumo, look forward to unceremonious ring-out by such things as:

Pressurized pipe-blasts of the WaterWorks!

Incoming meteors in Sumo in Space!

Runaway trains in Railway Rumble!

... but be sure to knock your friends into all of them!

Multiplayer Mayhem

The longer you survive, the more points you get! The first to reach the point goal wins. In Sumo, ties cannot be tolerated, and are settled with the white-knuckle, rapid-fire Sudden Death round!
