Sumo.io

Sumo.io turns the ancient sport into an instant multiplayer brawl: a ring, a crowd of wrestlers, and one rule — push everyone out while staying in yourself.

How to Play

Enter the ring and start shoving. Charge into opponents to knock them back; anyone forced outside the boundary is eliminated. The ring gets more dangerous as fewer wrestlers remain — endgame duels are pure positioning and nerve.

Controls

• Move: Mouse or WASD

• Charge / push: Click or Space

The Art of the Shove

Real sumo wisdom applies: raw aggression loses to timing. A wrestler mid-charge can't change direction — sidestep and their momentum carries them toward the edge. Champions win with angles, feints and patience, not button mashing.

Tips

• Sidestep charges; let their momentum do your work

• Never fight with your back near the boundary

• Push opponents into other fights — chaos eliminates for free

• Short controlled shoves beat one big desperate charge

• In final duels, feint first; the player who commits first usually loses
