Tutorial #40 A must know technique. NOT a puzzle.

PLEASE NOTE. This is NOT a real puzzle. Don't try to solve it as a puzzle. It is a demonstration only of a technique

VERY IMPORTANT.... Some subscribers have told me they are not getting notification of when I upload a new video. YouTube has been working on this issue. I am pleased to inform all my subscribers that if you click on the bell at the right side of the red subscription button, you should receive a notification from YouTube that I will be uploading something new on a particular day and time.
I will only be putting up notifications once or twice a month.
One advantage of doing this on my channel is that when I premier a new video you have the opportunity to chat with me as well if you wish.
For frequently asked questions FAQ

When you have 3 or 4 or 5 or 6 or more empty cells in a row column or block this "outside the puzzle" procedure is VERY helpful.

Frequently when solving puzzles there are several paths to take to solve the puzzle. SO MUCH DEPENDS ON WHAT YOU SPOT AND WHEN. In this video there is a 3X3 of 2,3 and 5. which means you can remove all other small numbers of 2,3 and 5 in the rest of the row. This will also help you come up with a correct solution. Thanks to Jim W for pointing this out.
ALSO note that 8 can only go in column 3, because block 3 has an 8, column 5 has an 8 and column 1 has an 8. See lesson 13 "There's only one place it can go"

NEW you can now go to my web site and see an INDEX OF VIDEOS under strategy headings. Clcik on the number and it will take you to the video of interest.

I am battling with Anxiety Disorder and with that my memory have weakened. So what I did is start to do brain games. Sudoku is the brain exercise that i have chose. I just started last week and i have been enjoying solving bc of you. Cheers to you!

You seem like a great teacher. The fact you go through so many comments, even if you have to sift through a lot of the same questions, shows how much you care.

My teacher handed out sudoku books, and I had to finish it for my homework.
Thank you for teaching me this technique! :)

[bridgendesar]

You got me into Sudoku, it's a wonderful way to keep the brain sharp, I thank you for that.

[debchambers]

I would like to thank you for the lessons you’ve taught me. I play electronically but I use the same concepts. The app I use forces me to be quick in order to get a good score but I still wouldn’t do as well as I do without your tutelage. It is SO fun and I think it helps keep my brain young.

[krystelltheisenescobar]

A great tutorial, my 8 year old homeschooler does Sudoku as a part of his activities and we really enjoyed learning this new strategy. Thank you!

[asmolbean]

This is so wholesome I love it.

My grandfather got me into chess and sudoku, but I never quite got the knack of any sudoku above hard lol

[rosethorns]

Lol...I’m stuck so I came looking for strategies. This is my first time looking and low and behold, this is the main technique I use every single time.
I need to find another video.

Hi, Sudoku Guy, ...just thought I would say a big thank you for your tutorials. Two months ago, I was an absolute dunderhead about sudoku. Now, thanks to you, I am solving fiendish and diabolical puzzles with little difficulty.
Keep up the good work.
By the way, it is now my favourite pastime.

[reeperplayz]

Hi sudoku guy. I absolutely adore your content you are probably one of my favorite Youtubers. I’m starting to use the technique you’re using in this video and it is insanely helpful. Keep up the good work

[iloveturtles]

I'm a 4th grader who just got into a sudoku contest. To me, sudoku is very hard, but your videos helped me understand it. Thank you very much.

[KpexSmith]

Amazing game, Great video. Your a wonderful teacher, Thank you so very much.⚓️🇺🇸

[tesstucker]

Great explanations! I find I can solve most puzzles with this technique and the pairs, along with the pairs patterns that I’ve kind of gotten in my head with experience. I have Tourette’s Syndrome and puzzles help me ground myself and decrease my tics after a long day 😊

[dinojaxon]

You are such a great teacher. You make me smile. Thank you!

[antrnf-gaming]

Who can dislike this guy? If you dislike the video I don’t know what to say to you.
Aside, this is a great method, thank you for this and I’m glad I came here.

[juanplasencia]

I solved two easy ones earlier today but I got stuck in four others, got frustrated 🤬🤬🤬and tossed them out... Can't wait to try your wonderful techniques. And you made me smile, reminded me of how happy I felt in High school when a mathematical formula finally made sense to me...thank you so much!

[akritisingh]

You're amazing. Something about this video warms my heart♡
Also, loved the content! Surely gonna use this trick :)

[suomenautisti]

Thanks a lot! I learned so much techniques with your videos and you explain these steps so incredibly well👍
Now I'm interested more in other variants like Thermometer or odd/even -sudokus.
I started also creating my own sudokus and variants. But you are biggest reason that I started sudoku and biggest thanks belongs to you!

[joanwilson]

You got me into Sudoku. Started just last week. Was stuck on a few but now I've seen this I can go back over the many I give up on and check for a number that appears in only one cell. I'll be back to watch your next video when I'm stuck again (no doubt). Thank you for your great tuition Sudoku Guy.

[davidcrabb]

Thanks I was hating little numbers until I discovered your tutorial no.40, and BINGO! I am now off on another level
