SuDoku

I am hooked, people. A lifetime crossword puzzle fan, I'm on the bandwagon with this new[ish] craze. It's called SuDoku. It's Japanese for "single digit" or something like that. The Daily SuDoku is but one of scores of websites where you can print out clean, logic-only puzzles. It's also the reason my [ahem] productivity has dropped at work. :)

This is the best resource I've found detailing How to Solve SuDoku.
