Sudoku Help - Square Allocation details

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.

Whenever you set the contents of a square in a Sudoku puzzle the program tracks which square was allocated so you can easily change your mind and make a different allocation.

To activate this screen you can press F3 key or select View | Allocations from the menu.

The screen details identifies the square that has been allocated and its current allocation together with how long it took to make the choice. The allocation notes can optionally be printed out with the puzzle. Any Sudoku squares that have notes are indicated with a star in the first column of the list so you can quickly look back through the squares that need special attention. The note you added is listed in the last column.

The list also includes allocation of tentative possibilities and impossibilities as well as square coloring - in fact any change you made - and these can all be easily undone/redone.

If you click on an entry in the list, the square will be highlighted in the grid - this makes it very useful for working back over the squares previously allocated.
