I have enjoyed the videos. Your instruction program is great. I have completed the program through the senior level and have learned quite a lot. And I am getting better. I was lucky to find your program and glad that I did. I would recommend the program to anyone really interested in Sudoku.

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.

Have finished all the videos. They have been a great help especially in spotting pattern, double doubles, triple doubles, etc. Solved all the puzzles with the videos…Thanks for the brilliant videos.

Your lessons are awesome! I really like how you build on the patterns. I am currently working on Senior lessons. Currently on vacation and taking a break from the lessons. Have purchased a book of puzzles, “SUDOKU ON THE GO” expert level. Before your lessons I could complete even one of these puzzles. I am now completing them in 45 min to an hour and not cheating at all. I am amazed at how much I have learned towards solving Sudoku. Your lessons really do bring fun to Sudoku! … Read more

I find the techniques that you teach in the Sudoku Professor lessons very helpful to solve the puzzles. I am at Sophomore 206 level. I realize that it is important to use the techniques and to practice as much as possible to be successful. Buying your lessons was money well spent!

I truly do enjoy having this resource . Initially it was a self explore method, which got me pretty far. But when faced with the hardest puzzles I was stumped . Help! How could I find my answers? Voila! , one day I received an email about sudoku professor, and my answers were solved. The professor has a wonderful teaching style that is appealing and clear and concise. I’m grateful because now I can better enjoy one of my favorite pastimes. Sudoku. 🙂

I am really enjoying your lessons and am getting better at solving puzzles. I struggle to remember all of the patterns and how to use them but have started to play your lessons again and that helps. Your methods have certainly improved my ‘logic’ and I am appreciative. Warm regards

I have found the Sudoku Professor addicting in a good way, helping me to sharpen up the old brain cells and provide an unexpected pastime. Thank you

Chad, I started–per your suggestion–on Freshman Video #2. I PICKED UP A TRICK I HADN’T CAUGHT BEFORE. JUST ONE SO FAR, BUT I WAS SO EXCITED, I WANTED TO TELL YOU RIGHT AWAY. It’s so simple, I’m amazed I didn’t catch it before. My worst fear in your videos to date is that I won’t have to enter each & every possible subset number in every cell. The complexity between Medium & Hard is so pronounced that neither my husband nor I thought there would be any other way. NOW I’M BEGINNING TO HOPE AGAIN. … Read more
