Best Sudoku game I

Ive tried a bunch of them, this is by far my favorite. I especially like that it is a wonderful tool for learning how to play. No matter what level, there are great features for learning more advanced techniques. My sudoku solving abilities have increased quite a bit in only a couple weeks. But its not just a tool for learning, its also a very playable game. Defaults are fine - Ive never felt the need to change them. Numbers are the perfect size and very readable. Kudos to the programmer(s).
