I am a university professor who does as little as possible with math. I work best in a verbal world so when a neighbor encouraged me to work Sudoku, I knew I couldn’t do it.

I would highly recommend the Sudoku Professors complete set of videos. I bought them all and they are the best on the market. I have found a ton of tricks and procedures in these videos. They are well worth the investment. I now have very little trouble solving the hardest puzzles. Thank you Professor!

I really enjoy the lessons in video format. I am at the junior level and find that using what I have learned not only makes the puzzles easier to solve but much more fun as well. I am really looking forward to the advanced videos and techniques so I can go after the difficult puzzles with greater confidence.

I have learned a lot about Sudoku while watching your videos. When I first started, I could not figure out the most simple puzzles. Now I can work the daily newspaper ones, with exception to the Saturday and Sunday editions which are the hardest.

Hi Chad I am impressed with your videos. I found them interesting and fun. I can now do the easy level of sudoku, and some of the intermediate level puzzles. Best Regards,
