Your records.
Written by the match server, across every device you play on. It keeps the finishing places it witnessed; score and lines are not here because nothing on the server saw them.
Kept on this device.
The theme behind the dojo and the match. Zero is silence.
IPPON, SHIHŌGIRI and the rest. Raise it if the music buries them.
The board dips as a piece lands and slides into a wall. Turn it off if it unsettles you.
Click a key to change it, then press the one you want. Escape cancels.
Your system asks for reduced motion, so the board stays still whatever this says.
Optional. You can play every mode without one — signing in is what will let a record follow you to another device, and what creating a dojo will need.
Your finishing places are recorded whether you sign in or not. Signing in is what ties them to you rather than to this browser, and brings the ones already played here with it.
