I am up to Senior level classes and I notice I am not having the difficulties solving puzzles I once had . Still stumble a little but am having more fun solving harder puzzles than ever before . Thanks Chad!

Greg Dodson

Your videos are excellent ! I have taken all the undergraduate lessons and have just started the graduate ones. Before I started watching your videos I found doing very easy puzzles quite challenging. Now I can do very hard puzzles. Your videos have helped me gradually progress. What is particularly helpful is the format of a lesson video and then another video going through the homework exercise puzzle. Your discussions about how to think about various scenarios are a great guide. Thank … Read more

You have taken my Sudoku proficiency up several levels! Many thanks for all your enlightening videos!

Hello Professor, When I bought your video’s I was pretty new at Sudoku and thought the only way to solve them was to use the “Brute Force Technique”. After watching some of your video’s I can see where the numbers go more easier than before. The techniques that you teach are very easy and straight forward it was worth the money . I would also like to say that the outfit that you wear in the video’s is a nice touch.

I am SO enjoying them. Maybe there is hope for me yet with Sudoku! I had already done the one thru nine (my son’s suggestion) and had stumbled onto the double-double but did not know what it was called. Your method makes a lot of sense…I never did like having so much information in one little square as some of the others recommend…too confusing! Can hardly wait for the next lesson!

Thank you for checking how I have been doing. I really appreciate it because it shows genuine concern. I have been really enjoying the videos a lot and I have been very systematical and I have solved many puzzles that I had purchased. You sir have been a perfect professor no question about that… I am very grateful to you, you have an amazing gift of teaching. You do not rush and you repeat you are really patient. I really wish you were here at times !!

I haven’t gotten through all of the Sudoku Videos yet. However, those that I did see were marvelous. Early on in the program, I learned that some of the videos are vital to the understanding of the next program. Therefore, I repeated the lessons and took notes…You definitely have an engineer’s mind. Most of us don’t, but I appreciate people who try to help others to see a process. I can tell you love to solve these puzzles, because you want others to see the process or logic that is involved. Yo… Read more

I wanted top learn more about Sudoku so surfed the web to see what was available. I came across your website and completed all of the free lessons. After completing the course I was invited to sign up for the remainder of your lessons. I have done this and what a great decision it was. You explain concepts in a clear and concise way that is easy to understand. I have no hesitation in recommending your service to others like me who want to learn how to solve Sudoku puzzles.

I am a student of the Sudoku Professor and have only good things to say about the service. For years I was a very frustrated Sudoku player,just trying to bluff myself through each game not having any plan or systematic approach.In fact I stopped playing on several occasions because of that reason. I can,t tell how many games I left unfinished. However one day I decided to remedy the situation and was surfing the internet when I came upon The Sudoku Professor,s web sight and thought I would gi… Read more
