    For everybody who wants to try out something new in sudoku, try shendoku, using the sudoku rules but playing two people, one against the other, like battleshipps. They have a free version to download at . Anything else they are bringing out or they are working on you can find at or at they´r blog . Have fun, I am. I specially like one slogan I heard about Shendoku: SUDOKU is like masturbation (one person)…. SHENDOKU is like sex (it takes two).
