The Sudoku Challenge

One of my friends asked me if I enjoyed working on sudoku puzzles. I told her that I was afraid to start on them because I suspected that I would become an addict. While I was my home, my grandmother told me that she worked them to help her stay sharp. After feeling like a slacker I gave in and worked the puzzle. As I predicted, I am now hooked. If you have not started, then fight the temptation.
