FROM IDEA TO DONE

Make it yours, in three steps.

  1. Start with the editable sudoku size example.
  2. The generator only removes a clue when the remaining grid has exactly one solution. Difficulty describes clue targets, not a human solving rating.
  3. Generate unique Sudoku, review the result, and save your creation on this browser or download a private backup.
