Sudoku Allocation List [Page 3 of 13]

Previous Index Next Next

It's often useful to check which Sudoku squares have been allocated, particularly when you have to make a guess as to what should go in a Sudoku grid square.

Sudoku Solver has an allocation list which you can optionally display (using the View | Options...) to the right of the grid. It shows the row and column of the Sudoku square allocated in the grid; the number/letter allocated to the square; the step number within the list and the time taken to deliberate over making the allocation. The final column gives text describing the allocation, if you use the Automatic allocation command to allocate the step this will indicate why the allocation was made. If the allocation was made to a step that has annotation text then the text is shown (and a star displayed in front of the row). An orange ball indicates step allocated by the user. It also records when you make tentative possibility assignments to squares. The Undo command undoes and deletes the last command in the list; the Redo command redoes a previously undone allocation (or setting of a possibility) - it will appear back at the bottom of the list. You can 'undo' as many steps as you like and they are remembered even when you save a puzzle and restart it later on. This is very useful if you find you need to backtrack after making an incorrect guess. The full list of allocations can be printed together with the grid.
