About the game

You control a sumo ball in an online arena and try to knock every other player off the platform.

Fast multiplayer rounds. Easy drop-in and drop-out play. A win for the last ball left on the platform.

netpro2k took the idea from the sumo minigame in Fusion Frenzy and the bumper balls in Mario Party. The project started with quick multiplayer rounds, and they built the rest by feel.

It ranks #395 of 588 games all-time, going by its jam placement until players rate it. How rankings work
