I am very new to Sudoku. In fact, until I watched Chad’s free lessons, I had never even completed one puzzle because after the obvious fill-ins, I had no idea how to narrow down what number went where. My husband has his own system, but, frankly, it looks too complicated to me. So off to the internet I went to see if I could find some lessons. After watching Chad’s free lessons, I knew his solving method would work for me!! I’m really good at following step-by-step instructions and that’s w… Read more

Learning lots! Trying to accelerate solving with the technique’s I have learned. Doing practice with Brown Belt Sudoku…As I do other puzzles I am beginning to notice the distinct patterns. That really helps. It’s funny because my brain is starting to do automatically rather than have to tell it what to do. I feel that’s amazing.!

I am very happy with Sudoku Professor…it is very informative. I forget stuff and will have to go back over it, and that is great that I can do so. However, what I do remember has been soooo helpful… all in all, I do enjoy what I have learned. Thank you. It makes doing the puzzles much more enjoyable. I love challenges. I am 74 years old. So far, I don’t feel I have cognitive problems, but I love playing games, and I think that keeps the brain active. Thank you again!… Read more

I take your lessons slowly. Your tips have been great and I am able to do the Globe and Mail “1 – 3 star quite well. I feel an air of accomplishment when I am able to complete them.

I enjoyed the lessons. The step by step logic is very helpful.

Hey Professor… As a beginning Sudoku player I searched the web, found your site and subscribed. At the time I was brute-forcing my games with real poor results. After watching your video’s on 1-9, doubling, and searching for patterns, I am now completing the Sudoku puzzles in the local weekly paper. I’m looking forward to receiving more lessons and maybe moving my game up the rung of difficulty a notch. Thanks again.

I have viewed and solved all the sudoku puzzles you have sent by printing and following along on the solutions. The help has been tremendous!!! Thank you for your step-by-step instruction. You have the heart of a teacher and I’m a very grateful student.
