Love the pencil mark feature. Very easy to use. Very addictive.

This is an astonishingly, spectacularly, breathtakingly awful game. It doesn't have autopencil, undo, heck it doesn't even have autoerase or highlighting. Games would have to be ten times harder to be suitable for complete beginners. This would be good as a high school programming project but cannot be meant seriously as a game to be played by people. By far the worst Sudoku I have ever seen.
