Totally worth every penny of the $3 I spent on it

Im a Sudoku fiend and have tried several Sudoku apps, and this is the shining star. I love the different looks (newsprint, yellow pad, etc.), the different difficulty modes and the note functionality is solid. I would have given this five stars, but the app has crashed a few times. My game was never lost though, so it wasnt a huge deal.
