A 2 player sumo wrestling game online: two chunky rikishi grapple on a circular dohyo that keeps shrinking. Dash to shove, dig in to hold your ground, and push your rival clean out to win the round.
About Sumo Smash
Sumo Smash is a physics shoving match played on a ring that never stops closing in. You and your rival slide around on momentum and friction, so every move carries weight and every stop takes a beat to settle. Dash toward your target for a hard, cooldown-gated lunge, or plant your feet and wait 0.6 seconds to dig in, a heavier stance that shrugs off incoming shoves while making your own hits land harder. The tactical heart of the game is timing that dig-in against an incoming dash: dig too early and you eat a full-speed collision anyway before the stance kicks in, dig too late and you get launched clean off the sand. Every ten seconds the dohyo shrinks a little more, so the safe patch of ring you were circling around slowly disappears and stalling becomes a losing plan. Play best of five against ramping CPU opponents or grab a friend for same-device local 2P, dividing the screen into two drag zones for a couch-multiplayer shove-fest that rewards patience as much as aggression.

How to play Sumo Smash
Move your rikishi around the shrinking dohyo and slam into your opponent to knock them back; the harder and faster you're moving on contact, the bigger the shove. Stand still for a moment to dig in and become heavier and harder to push, or hold your dash to lunge forward for a big hit once its cooldown ring is full. Push your opponent's entire body outside the ring to win the round; first to 3 round wins takes the match, but the ring keeps shrinking every 10 seconds so nobody can just turtle in the middle.
Controls
Desktop: WASD to move / SPACE to dash (Player 1), Arrow keys to move / Right-Shift or Enter to dash (Player 2, local mode). Touch: drag your half of the screen to move, tap the glowing 💥 button to dash.
Tips & tricks
- Dashing has a 2-second cooldown shown as a ring around your rikishi — don't waste it chasing air, save it for when your opponent is close to the edge.
- Digging in takes 0.6 seconds of standing still to kick in, so start planting your feet just before contact, not during it — a dash mid-transition still connects at full force.
- Relative velocity is what matters on impact: a fast dash into a stationary opponent knocks them much further than two rikishi drifting into each other at low speed.
- The ring shrinks every 10 seconds, so don't waste the first shrink circling for position — force an engagement before your safe patch of sand disappears entirely.
