I’ve really been enjoying the tutorials. I’m not a Sudoku “addict”, but I’ve always enjoyed doing the daily puzzle in our newspaper. I always used the “Brute Force” method, and I actually discovered “double-doubles” and “row/column elimination” on my own, but often with harder puzzles I knew there was some logic key that I just wasn’t seeing. Now, I’m always really excited when I see a pattern in the puzzle that the Professor taught me about. I solve puzzles in a fraction of the time it used to take, it’s much more satisfying, and more fun! I’m up to the Junior level in the tutorials, and solving all but the most difficult puzzles is child’s play now.

Thanks, Professor, for giving me the keys to Sudoku secrets!
