Room Codes & Timing Duel · Second Sumo

Second Sumo is a browser WebSocket duel: share a room code, watch the clock, and stop closest to 0:00. The loser gets shoved off the platform. Matches are intentionally ~60 seconds — rematch immediately instead of overthinking.

Calibrate once in a friendly room before inviting chaos friends. Network jitter matters more than fancy reads; if ping spikes, play safer and stop a hair early rather than overshooting zero.
