Hi Chad. I started to play sudoku about 2 months ago and never used to mark any other numbers in until I got to the hard puzzles. And that's when it got to be too much information just like you said. That is when I contacted you for help. Thanks and looking forward to more lessons. — Mike

I find your instructions to be very helpful, as a matter of fact after looking at the 3rd lesson, I was able to figure out how to complete the puzzle. Because of your instructions I have bought a Sudoku puzzle book and I am finding the easy and medium puzzles a snap. — Troy

I wish to let you know how much I am enjoying your videos. I admire your professional approach and the extremely clear way you make it all come over. Very many thanks. — L. Jarman (Rugby, England)

Dear Chad, I want to thank you for taking the time to produce your Sudoku videos. Although I've reached the point where I can do a few hard puzzles, I don't seem to be able to push forward and do them successfully on a regular basis. Your videos have already given me a few new ways of looking at the puzzles. I am looking forward to working through the whole series. Sincerely, — Jean

Hi Chad, I'm hooked. I was seeing Sudoku everywhere & I just didn't get it. Then when I was preparing a CARE box to send to my grandson in Iraq, my daughter suggested puzzles & Sudoku was one on them. I told her I didn't get it but I never tried. She said she would show me, but I was impatient to know, so I went on line & found your Sudoku classes & now being a numbers person, I'm hooked & look forward to each lesson. Thank you, — Barb (Wesley Chapel, FL)

Thank you very much, Professor. I did enjoy the videos, they are very helpful and easy to understand. I'm sure this appreciation is shared by many of your students. Wishing you all the best. — Agnes

So far so good, you definitely make yourself understood. An idiot could understand. Please keep up the good work. Thanks again! — Kathy Connell

Hi Chad: I enjoy your lessons very much. We get two newspapers and they each have a puzzle, so that keeps me busy most of the time. I also have a magazine of puzzles. Being an 86 year old, it gives me a great excuse to sit and WORK. HAVE A GOOD WEEK. — H. Miller

Just a short note to say thanks for taking the time to create the videos. Good investment for me. I'm still learning, mostly to trust my instincts and not 2nd guess myself. After watching your vids I am presently completing about 60 to 70 percent of the medium challenge puzzles. The easy ones I am pretty much trotting through, and I can sit and watch the evening news and do 3 or 4 back to back without much hesitation. These things are addictive for sure. Thanks Again, — R. Weeks

I thought my method for solving was good, but your method is much better and results in a quicker solution . . . . — P. Hochstetler

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. — C. Oake

Great stuff, Thanks for the lessons. I am using your two and three in box or column primarily, and when that fails, stepping back and filling all the spaces in the mostly filled areas. I owe you. Thanks, — Gary Cramer

Hi, Chad, I just got lucky and found your lessons right after I'd started doing sudoku. I've been a crossword person for years and finally decided I had to see what all the hoo-ha was about. The lessons are great. Thanks again, — Tamara

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. — Lonnie Lloyd (Hermiston, Oregon)

Good Morning Professor, Just finish watching your First lesson and already know more about solving these Sudoku Puzzles than I did for the last few years. Can't wait to see what is next Thank you, — Charles

Hi Chad-I'm just a beginner and your lessons are very important. I look forward to the next one. — Pete S.

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. — "Tumbleweed"

Hello there Professor, I love your lessons because your teaching makes it so simple for me. I watch my husband faithfully work [Sudoku puzzles], but he has no patience with my slow understanding, just like I won't let him teach me golf, being that I hit left handed. Keep sending them. — Laura Calhoun

I am very impressed with how easy you make learning Suduko. Having never played this game prior to receiving your first lesson, I am feeling like I am getting it. Each lesson has helped me even more. I will highly recommend your services to anyone who asks. — Jim Warner, Texas

I viewed all four of the videos you emailed me and they were great. Thank you — Carole

Hey Chad, Thanx for your commitment. I think you have given me a great heads up on the matter. I never knew how addictive it could be. I think I'm going to have to take up Sudoku anonymous therapy classes now. So long and thanx again. — S. Williamson

Professor Sudoku, Your Lessons are clear, concise, helpful and talked me off the ledge... I'm determined to "get this" and with your help I'm sure I'll succeed. Thanks! — Cynthia

Hey Prof. The lessons are appreciated. They are a more organized approach than I have used before. So they are a help. Thanks. — Jack Rhine

The videos are a great help and are time saving. [Puzzles] are a lot easier to solve when you don't have too much information. — Clewood

Dear Sudoku Professor: Thank you for emailing me the lessons, I am now anxiously waiting to receive the 5th lesson and then I wonder what is next. I love watching your videos, and I have them all saved. I have learned a lot and from your techniques... I am a very busy housewife and a grandma I hardly get free time to solve much. I have also forwarded your website to some of my friends. Again thanks a lot for the videos. — Guity

Your video is great. I love the game, and now I can play it better thanks to you. I can enjoy it. Its lots of fun. Thank you so much. — M. Belair

Hi Chad, Your lessons are FANTASTIC!!! Thank you so much...I am enjoying them very much and I have forwarded them to friends as well. Your "character" and your method is GREAT! My girl friend and I (both retired engineers) just love it. Thanks so much. Sincerely, — Bruce

Chad: I watched all four lessons & enjoyed them. I am able to do the easy puzzles so far with little difficulty and I had never done them before. I would have to say that the lessons have been very helpful. Thanks so much. — J. Rivas

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, — Louise

Hi, Chad I truly enjoy your Sudoku lessons. Explanations are clear and detailed (just great !). Keep on your good work, Chad : I just can't wait for my next Sudoku lesson ! Have a nice day and take care. — R. GERVAIS

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

Greetings, Sudoku Prof (SP for short) Pursuant to your request for feedback, may I say without reservation that your video lessons are clear and to the point, which is just what they should be. Using your techniques are improving my game considerably. Thanks! Your humble student, — Arlene

Hi Chad: Your videos are terrific and I have sent your website info to a few friends and hopefully they will contact you and get started. Have a fine day. Cheers, — J. Rutherford

Chad, I think you videos are excellent. I am still learning, and I sometimes replay them all to refresh my memory. I am a senior, and I find I cannot retain things like I did when younger - like you, I have told several of my friends about your lessons, and told them how to get the videos. I am sure you will be hearing from some of them. Thank you again...I look forward to the next lesson. — Fred

Love it!!!!! I've definitely enjoyed the teaching videos, and they have been a great help to me. I have a better time doing them. Thank you. — Suzanne D.

Thanks for the lessons. I am usually fair at the easy ones but at my age, 65, I need to push my brain to get some gray matter exercise, and you help with that!!!!!!!!!!!!!!!! — J. Kimball

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

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, — Sheldon

Thanks, Chad, this is great! Yes, I'll be happy to spread the word. — Connie

Hey, your lessons and method of teaching are great! I just finished winning a game in record time using these lessons. Your technique of going through the numbers was helpful, and your concept of "too much information" was particularly helpful. I am looking forward to the next lesson. — F. Tinker

THANK YOU!!! Where do I begin, I wanted to send you this information but, I didn't want to seem like I was bragging. I have done all the puzzles, including the ones you just gave information on how to look at the puzzle from different ways using your system. IT WORKS..... I'VE LEARNED SO MUCH FROM YOUR LESSONS I APPRECIATE YOU BEING THERE .. Thank You Again. — Philip
