Here's a page from the extensive help system for Sudoku Dragon. It is available as a help screen when running the program. To get the full picture Download our Sudoku Dragon and see the screen in its context.

We now offer an alternative product only available for download from Microsoft Store. This shares many features but not all of them. For documentation of the SudokuDragon for Store version see its separate help section.
