Marks
These times never leave this browser. There is no account and no global leaderboard. Finish without Hint or Peek, then Save. Five names per board type.
Daily boards list under their UTC date. Timed runs show as timed 60s. Clearing site data wipes the list — export is not built yet, so treat Marks as a local scratch pad.
What counts
A clean finish means exit reached (and keys collected when the mode needs them) with no Hint and no Peek. Pause is fine. Switching tabs pauses the clock; it does not spoil the run.
Board types
Size, mode, daily date, and timed flag each make a separate list. A twelve classic practice time does not replace today’s Daily entry. Outline shapes on the homepage save under their own labels when you finish clean.
