Difference - Show the difference between some of the cells
Compare - Show which of two bordering cells has a larger value than the other

Using More Clues

The Sudoku More Clues add-on works on all sudokus, depending on your license. There are three license variations that are explained in the next section.

If you don't have a license for the sudoku type, the results will be watermarked. If you use (test-drive) the More Clues add-on without a valid license, the results will also be watermarked.

Sudoku symbol types

The More Clues options will work for sudokus with number, hexadecimals and Roman numerals. It will give unpredictable results for sudokus with letters and images, i.e. there is no numerical 'Difference'or Çomparison' for two letters or two images.

Checkerboard and Nonconsecutive

Even though the More Clues add-on can work with the Checkerboard and Nonconsecutive sudoku variations, it is not recommended to do so: Both Checkerboard and Nonconsecutive sudokus already have additional visible and invisible clues incorporated. Adding "More Clues" will reduce the difficulty level of these sudokus.
