:The only thing which can make the difficultly change is how many cells are pre-filled. If 0 are filled then either both solutions are correct, or it is impossible to know which solution is correct. If 1 cell is filled, then it is easy to complete the rest of the grid. If 2 are filled, then it is even easier to complete, and easier again with 3 filled. --[[User:Pudder|Pudder]] ([[User talk:Pudder|talk]]) 11:01, 28 July 2015 (UTC) | :The only thing which can make the difficultly change is how many cells are pre-filled.
