How to play
Fill every row, column, and outlined 3×3 region with the numbers 1 through 9, without repeating a number.
Select a square, then use the number pad or your keyboard. Duplicate numbers turn red, but the game never identifies which entry should change.
Turn on Notes to pencil in possibilities. A full conflict-free board is checked automatically.
