Today's Ranking Game

This lobby is where a player reviews the official conditions before an attempt begins — the timer never starts and the grid never shows until you enter the event itself.

Event conditions

FormatOne official Sudoku
AttemptsOne submission
ToolsNo hints or live error checking
ResultProvisional until verified

Before entering

  • Sign in to the player account that will own the result.
  • Confirm the event window in your displayed timezone.
  • Use a stable connection and supported browser or app version.

Protected attempt: the start time is recorded by the server the moment you enter, and elapsed time is derived from that record — not from anything sent by your device.
