How to play
Fill every row, column, and 3×3 block so the numbers 1–9 appear exactly once in each.
If the same number is duplicated in a row, column, or block, those cells are softly highlighted. Your entries are never checked against the solution while you play.
Use Memo to keep candidate numbers. Your entries and elapsed time are saved automatically on this device.
