Do you like Sudoku puzzles? Every so often, I get on a Sudoku kick for a week or so, feeling an urgent need to solve one each morning before embarking on my real work for the day. Eventually, I encounter one that is so maddening that once I do solve it, all others seem anti-climactic and I break the habit for a while. That was the case with this one, which took way too long. You might have better luck with it than I did. Then again, it might take you as long as it did me. So you'd better not go there.
