Great sudoku game

I like to jot down options in the squares as I cant remember what I have already done as I work through the game. This app lets me work like I do on paper, which is great. So far I have not had any problems with it. I dont know how the scoring works but dont really care. It is nice to see how long it took to do a particular puzzle.
