The lessons have been very helpful! I received a “Sudoku a Day” calendar last Christmas and was stuck on the hard puzzles. Now that I’ve been through all of the lessons, I’m keeping up with the puzzles and don’t have any outstanding unsolved puzzles.

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.

I have just started doing sudoku puzzles and was pretty much lost till I stumbled onto your website. Thank you so much for your videos. They are wonderful, and I have found success after watching your videos. You are the best thing I have found to help me understand how to solve a sudoku puzzle. I don’t know what to say except thank you so much and keep up the good work. I may have given up the puzzles if I hadn’t found your web site. Thank You so much.

I have found the videos to be very helpful. The way they are presented is very good and the explanations are very helpful.

You are definitely delivering what you promised, and we highly recommend membership to those people who see soduko puzzles in the newspapers and think to themselves “You’ve got to be kidding me! These things aren’t doable!

I think your teaching in the videos is exceptional. I am up to the senior level and have learnt so much. My Sudoku solving has improved enormously and I am happy with the results.

Veronica

Videos are very good. I have made very good progress quite quickly as a result of the techniques set out.

Alan Gall

Thanks for your assistance. I have thoroughly enjoyed the process.

Bill Rubel

I do enjoy the videos. I find them helpful. I received a book of 90 “easy” Sudoku puzzles and find that I am able to solve most of them. I did look at a couple of other online sudoku aids but as you note, I found them difficult to work with. I generally try one [puzzle] each day, and as I said I do figure out most of them. Thanks for your help

Think they are great.Clear to the point and you have great patience with your students. It is easy to go back and see where you made your mistakes. Best money I ever spent. Sincerely,

Mr. Chad Barker, I recently bought your Sudoku lessons. I was doing Sudoku close to 1 year, I read several courses that were free on the Internet, and I could not grasp when they explained, like you mentioned, x-wing, xyz-wing, Swordfish, etc, etc. After using your method after 1 or 2 days I realized I could complete diabolical Sudoku’s in about 30 to 35 minutes. Now I only works on diabolical Sudoku and have fun doing it. Best regards,

Michel
