Good teaching app + good solver – Sudoku 101 (Free) Review

I've played a few Sudoku apps on the iPhone, but this one's my favorite. Here's why: 1. It's got a nice, simple uncluttered interface, yet still has all the things you'd expect it to do, like auto or manual pencil marks. 2. The teaching mode is actually pretty helpful and has taught me a few tricks I wouldn't have otherwise known. The gimmick of the college course outline is a little too cute, but that doesn't get in the way of the actual teaching mode. 3. It's got a solver, so I can put in a puzzle from the paper or a book and get hints on it if I want. 4. The best feature. The price! (can't beat free)
