ACTSudoku is a great sudoku game, reasonably priced, with almost all of the options you could want in a sudoku game. While the graphics aren't the best ever seen, they game play is nice, progress is saved, and there are some good hint options.

One nice feature is the hint button. If you are stuck, this button will give you an little help. ACTSudoku also includes the option to turn on automatic pencil marks -- if you're lazy like me.

One of the features that ACTSudoku prides itself on are the nearly infinite game puzzles. These puzzles are nicely categorized into 3 different difficulty levels. Also included in the game is a good level of documentation on the game of Sudoku. Including general game play rules and solving techniques - great for beginners.
