Sudoku!

The other day my wife was telling me about the sudoku puzzle that they like to do in her office (USAToday is where they get them). I had played with some of these puzzles a year or two ago, so I was anxious to try one out, because they are pretty fun. Today I was going over to the MAA website and saw there is a nice column about about Sudoku! Check it out:Sudoku Variations. It talks more about the history and variations of the game than it does about the math aspects of it, but it is still a good read.
