My friend Bob is a Sudoku guy too and he called me this morning wanting me to check out a puzzle in our local paper. It was a tough one. I took it to my favorite Sudoku site and entered it to find that it rated off the charts in the level of difficulty so I didn’t waste any time trying to solve it. Later Bob called and said that he found a Sudoku site that had some good strategy notes. I thought it might be a good idea if I made a note of the site.
