GameZebo: "Being a complete novice, I didn't realize how much nuance Sudoku actually has. Sudoku for Dummies was developed in conjunction with Wiley Publishing, creators of the line of black and yellow Dummies books we've all read for years. When you boot up the game, the same hand-drawn googly-eyed guy helps walk you through the techniques just like the books. The layout and aesthetic is taken directly from the famous tomes, helping you feel right at home.
You can jump right into the Sudoku puzzles contained in the game, or if you're like me, you'll want to hit up the tutorial levels first."
