If you like Sudoku, you owe it to yourself to get this game.

User Rating: 9.5 | Zen of Sudoku PC
While Zen of Sudoku doesn't revolutionize Sudoku puzzles, and while there are other options available online, including free ones, this game is worth picking up if you're a Sudoku junkie like me. It provides you with pleasant backdrop, soothing sounds, and a full range of difficulties. You can make "pencil marks" to keep track of moves, and if you're stuck the game will give you a hint about your next move, and even teach you some Sudoku strategies along the way. It even has some achievements to keep you coming back for more.

Zen of Sudoku will run on just about any PC, and I love doing a quick puzzle on my netbook on the train, when I'm supposed to be paying attention in class, or even while I've got the TV on at home. Bottom line: if you like Sudoku, get this game, it'll provide hours of entertainment while you sharpen your mind. Cobalt says: 9.5 / 10
