I’m finding the various techniques very helpful, although I have to get used to the terminology ( triple double; double double, quadruple; ect.) Haven’t had a lot of time to devote to the videos but the little I have watched and used have already made a big difference. Thanks for offering these instructive videos.

I’ve been trying to solve sudoku puzzles in a certain newspaper for the last 6 months. These puzzles are only rated medium or hard, never easy. I’ve finally solved my first medium puzzle using your techniques – mind you I’ve only completed the freshman exercises so far. So what seemed impossibly difficult at one time has become solvable thanks to your excellent video classes.

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.

Great job. All the other sites want to sell you something before you learn anything. I take it back, you learn that you don’t need them and their jumbled crap. Keep up the good lessons I will recommend you to my friends. Thanks,

I appreciate your videos so much but I am a slow learner and have to do the puzzles over several times. But I am determined to get it all. I am so happy that I ordered the extra videos. I am enjoying them very much. Thank you so much for putting that all together.

The Sudoku Professor doesn’t simply give you “tips” to help solve puzzles, but rather presents you with a logical way to approach and think about sudoku … Anyone can do simple “cross-hatching” or fill the squares with numerous candidates … There’s no logic in that – no use of mental acumen … The joy in solving sudoku, especially the extreme puzzles, is figuring out the patterns … The techniques which Chad shares help to unlock those puzzles without endless frustration … Once you learn the value … Read more

Hey Sudoku Professor, Thank you very much for you help. I’m up to the Junior 1 & 2 Puzzles, and today I finally made it through a “four star” newspaper puzzle that took me days to finish… but I did it!! The “too much information” rule is, I think, the most helpful rule I’ve learned. I’m looking forward to the Senior puzzles and think maybe I’ll be able to finish my 4 stars sooner after I work through those. I’m addicted! Sincerely,

Kathy

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 !!
