The Sudoku craze

I've made the mistake recently of getting addicted to sudoku, the newest craze in logic games. Thanks to www.websudoku.com, I can play as often as I like. Which has turned out to be a horrible thing, especially considering the fact that I play it for hours on end. If you dare, check it out. But I must warn you, it does have the potential to suck the life out of you.
