![]() ![]() Following all the rules you end up with two or more different solutions from the same starting squares. Multiple Correct SolutionsĪnother example of a puzzle that can not be solved is when it has multiple legitimate solutions. Sudoku Dragon has a hint that will show any incorrect allocations that you have made. Going back and 'Undoing' all the allocations, it turns out that allocating Dd to 8 was the mistake, it should have been a 9. SudokuDragon will spot this incorrect allocation using its hint facility and let you use undo to go all the way back and correct the square allocation. What has happened is that an incorrect choice was made for a square somewhere else and the repercussions of this has shown up here. If you run through the numbers 1 to 9 you will find there is already one of them allocated in a shared row, column or region. In this case there are two squares Bi and Ih that are in a bad state, no numbers can be allocated to these squares at all. To download this puzzle and see it in Sudoku Dragon click here.
