As you start solving more difficult puzzles being able to spot a 3X3 is essential. if you spot a 3X3 in a row, block or column, you can safely eliminate other small similar numbers in that particular row, block or column which are part of the 3X3. . Watch for this in difficult puzzles.
Ooops Did you notice that I missed a ramification at 7.54 of a 6 which could go in Block #3

Robin sir,
Your method of explaining is fantastic. I am 61, a medical doctor, and was always at my wit’s end while solving the puzzles till about a month ago. Then I came across you channel on TH-cam and I believe that there has been a tremendous improvement in my ability to solve the puzzles with varying degrees of difficulties. I take out time to see your tutorials in the limited time that I get, but they are really amazing. God bless you.

Lost it at "There are no 7's in these three columns. Except for this one. And this one." That was super funny to me for some reason.
Glad you saw the humor! Ryan.
You are the best Sudoku teacher! Thanks so much for sharing your knowledge! You do it in such an interesting and entertaining way, I never get bored watching and learning from you.

I already know most of this but I love watching these videos. Thank you, Sudoku Guy. This is great content and you're an endearing man.
Thank you ARDistilled. there is much more to come. Have fun
I'm 76 and I have problem's with keeping #'s in my head - so, I enter the #'s on the squares. I didn't think I could get excited about something with numbers, except my check book - but you have opened up this wonderful game that will help me through this MN.. winter. You're a great teacher, just ask my wife because I am almost even with her abilities. Bless you, Sir.
Gee thanks for your support and encouraging comments. Robin

@@SudokuGuy I’m the Jen part of the Merv ( who is my husband) ! He thinks I’m great at Sudoku because I’m always trying to complete one! But that’s my story- I’m still trying ! I remain determined to conquer it! I do work out
Some but not all. The only thing that keeps me trying is you, Mr Sudoku Guy! There’s always a way, you say! Thank you!
Hi again! I dropped out for a while but now am back to learn more. This one was especially helpful, thank you.
And as always, you are looking good! I appreciate all of your tips. I may not understand it all at the time but later

_"Some people say you go too fast!"_ -- Funny, I watch these videos at x2 speed. LOL
Can't win them all eh!
@@SudokuGuy LOL I have a really hard time learning if I play the videos at normal speed. I almost never got any value from lectures at university because of my ADD. That's one of the reasons I love Sudoku. It's something I can concentrate on to quite my brain! :-)
@@dienekes4364 I have the EXACT same way
20:00 not sure how that fixes the 9 at the bottom, (could still be a 4 ?) but I'll watch it again (I think that 4-9 could have been the other way round)
I think it wise to look at it again. the 8/9 in cell 8 has the 8 removed leaving a 9 to go in that spot. Hope this helps
@@SudokuGuy nope it still makes it a 4-9 matching pair
Its easy to miss things sometimes. Don't worry
Really cool, thank you.
My pleasure.

Simply amazing lesson.
Glad you think so! Michal.
Another name for the 3X3 is a triplet. and a 4X4 is a quadruplet.
Really some nice work you are doing.
Thanks a lot Oliver. Please tell others. I need more subscribers.
Very good teacher often though your right side covers part of the puzzle
Sorry. I'm doing my best to correct that.

It's so much fun when you can solve a more difficult puzzle using the techniques learnt so far. the 3X3 pattern plays a very important part in more difficult puzzles. subscribe and you will see many future tutorials where the 3X3 is used and spotted.
The most fun channel!
YOU have made my day Mia. there are many future tutorials which cover 3X3 or triplets. What the next tutorial for a demonstration of a triplet. or 3X3

Don't you worry Sudoku guy I sure do spread the word that you are the best to learn Sudoku... plus I forgot to mention😭 THE CLEAVER WOW! that is awesome. I never thought I would hear myself talking about Sudoku like this. When I first look at Sudoku I thought it's just a bunch of numbers 1-9 & U have to fill in each squares😴 how can that be fun? Well, Sudoku guy here I am replying back to you 😁 again thank you 👍😃
hi sudoku guy,
your tux looks great.
from now on i shall wear my ball gown & tiara to do my puzzles.
Love your sense of humour
Great!
11:8 There is an 8 down at (col 4, row 9), which blocks the entire col 4. That leaves you with only two places to put an 8: (col 5, row 2) and (col 6, row 3).
You are right but what about col 1 row 2?
Love your videos and love your personality!!! You remind me of my piano, voice, theory and music history instructor from Oakville Ontario. His name was Dr. John B Younger. I miss him. Been at Sudoku for just a week. I’m obsessed. Where in Canada are you?

I love this soduko guy. Funny and explains very well. Now my question is why not make an app for soduko. I fly a lot and I look forward to solve soduko on a plane from United magazine. It was difficult to put the little numbers while solving when you have a small space. That is why an app would be better.
I suggest you buy a book by Will Shortz which has one puzzle per page. That's how I learnt to do puzzles on flights There are apps you can download, but be careful some are poor. i suggest "Enjoy Sudoku" Aslo 1 puzzle per page.
Oh Baby, a Triple!

Could you please explain why you do the rows, then the columns then the cross? I always just do the cross. It seems to me to be much, much faster.
+Malte Christensen You will notice that in my tutorials I combine techniques. For learners I show one step at a time. Once you are epxerienced which I know you are the using combinations of techniques is fine.

Hello Sudoku Guy!
First off thanks for the videos as i'm recently getting into doing these Sudoku puzzles and they're really enjoyable and your videos are really helping me getting some techniques to do them. I was wondering if you, or anybody else could help me explain something in more detail so that i can understand it. At about 20:00 (20 minutes in) you have a 3x3 on box 1 and 7. The missing numbers are 4,8,9. You figure out that the 8 is on box 1, but then how do you figure out which cell the real number 9 is in? as you have two cells that are possible 9s. Thank you for your videos, they're great! :).
thst answer will come as you solve other parts of the puzzle. Good question
@@SudokuGuy Cheers for the answer! I figured the most i could of done with that situation is that i could of gotten a 4-9 matching pair. I thought that you used some super technique that i didn't know about. I'm glad that the case is different and that i was on the right track. Much love from Sweden! :).
Happy new year😀

Will you please explain to me why the 5 doesn’t appear on the top line at the start of the video? I can see how you come up with 1,3, and 4. Surely, there needs to be a 5 on the top row. I will have to revise the previous videos to answer my query I think 🤔 thank you for all the tuition, greatly appreciated 😊
Sorry AngelH. it is not needed. I suggest you look at lesson 1-12 again.
Is there any advice for when you have 3 or 4 boxes that have 2-4 numbers?
Yes I have done many of these and more are to come. See below and look at tutorials from 20 up to 81.

Thanks for your comment. I will work on this.
I can’t see how you got those matching pairs before we started
I made them up to show a technique.
Hi! I am Theo from Germany and I like your explanations: You are the best! One simpel (perhaps stupid?) question to this lesson: Is there such as a hidden 3x3?

I am a beginner and still working on easy to moderate puzzles. I am having trouble with matching pairs. I want to put a third number there, like 964, 964, and 9... I want to put the 9 in both other spots that you may claim is a "matching pair". Can you explain matching pairs differently?
Good question a 3X3 is 3 n small numbers which can only go in 3 cells. We don't initially know which number will go in which cell, but usually once you get one number you get the others. re matching pairs .... only 2 little numbers can go in 2 cells e.g. 36/36 No other little numbers can go in those cells at any time. Look at lessons 3,8,11,14. Also go to my web site sudokuguy.com and scroll down to the index of techniques and tricks. You will find many more example of tutorials which cover matching pairs. One of the great features of a matching pair is that if you solve 1 number then you know the other number in the other cell. All the best You can do it!!!

... When you completed the first column: I agree that the 8 goes in the 2nd cell, I thought the bottom 2 cells of the first column would become a 49 matching pair at that point as I couldn't see anything that automatically confirmed which would be the 9 or the 4. Is this a mistake or can you explain if there is a rule I have missed? Many Thanks :)
+Wilma Millar Hi Wilma. You are right. I jumped ahead instead of putting in a 49 matching pair at the bottom of column 1. My apologies as I missed a step. If you look at block 9 you will see that by using LCR a 4 will go in cell 7 column 8, thus I jumped ahead and put the 9.in cell 8 column 1, because the 4 goes in cell 9 column 1. No you didn;t miss a new technqiue, I just jumped ahead. Sorry.
I came here to the comments just to see if anyone caught that.

18:53 he could put 6and6 at the bottom of the middle box at the very beginning, and those 6's says there cant be that 6 on the left of them so its 5, then you get 7 and 6 in that box, i guess he missed it on purpose

Explain the 1-3, 1-4, and 3-4 on the top row. Are they just arbitrary numbers you chose as an example?
Hi J. the 1 is there because of TMB and the remaining 2 cells have to be 23/23 matching pair. Yes with the 3 empty cells you have a 3X3 but it doesn't help a lot once you get the 1.
Bonjour de Belgique à tous les Sudokistes du monde entier.
Thankyou Merci Robin
11:09 8's can go in the top centre block in either the central square or the right bottom cell as two little eights. But you'll probably come across it again later. 11:48 3's running across the bottom row blocks; because the centre bottom row is already full a three has to go in either of the top two row cells. Which means that a 3 can only go in the bottom left corner cell of the bottom right block. Immediately after the 3's because a four can go 4's in the top right block two central row cells the ramification of that is a 4 has to go in the top right block bottom centre cell. I think your teaching method must be working: I am starting to talk just like you. Lol
Thank you for your comment Chris. There is much to learn. Hang in there.
What whiteboard is that? Or did you make it with a grid?
+alberto barbosa I made it with the help of my friend Burton who does vinwl stickers.
Thanks

I have three pairs in a row so is there a teick for that? 14-19-49 in a same row???
Hi Alejan. Yes it is possible to have 3 matching pairs in a row column or block. Just continue with your puzzle solving and everything will come together for you. Hang in there and have fun
@@SudokuGuy Thank you sir. So there is no trick for that. An I am confusing how in matching sometimes. Such as 179 167 279 369. lets say this. Which pairs whould be selected correctly. Do you have a video for this one?
Robin, are those techniques , all, your own, inventions ?
I'm not sure but I can say this. I use terminology which can be understood by the average person. if I use another persons technique I always give them credit.
20:03 error, it also could be 4

@@SudokuGuy your site is superb :)
Why u already writing the matching pair no?i get confused
Plz, write infrent of our
Please listen to the video again . I actually explain why. All the best have fun.
20:00 There are 2 places 9 can go. So, why you chose the top one?
See my comment below.
I don't see where he's commented on it Oner Tapacoa
There DOES seem to be 2 places for the 9
I still want to know what to do if I put them wrong number on.
Start over again for the beginning. Sorry this is my suggestion. Robin
where do these pairs of numbers come from : 13,14,34??. i don't understand. Help me
I made them up. This to teach a technique. A 3X3 is very important in solving. You will come across them any times. I suggest you watch the video again. Hang in there
@@SudokuGuy but why not 5 but 13,14,34. I do not understand this problem
@@SudokuGuy I thought forever but did not understand
@@2..t.thienanh973 Please let me know the clock time you are referring to. I'd be glad to help.
Hhhhhh bom bom bom bang well done
Neat eh!
Triplets!
Means the same.
Captions are not available on this one at all. :(
Yes they are I believe You can turn them on by going to the bottom of the video and clicking on the cc Robin
@@SudokuGuy They are not. You can verify yourself.
Would you like to add subtitles to this video the subtitles are listed, the other videos have subtitles turned on
how can I add the subtitles in Dutch?

First rule of any kind of teaching/training - NEVER NEVER NEVER talk to the Board!!! Use some type of pointer and ALWAYS face the student(s).
Well said! but I have to face the board in order to enter information.

10:12 Middle top block. You have the bottom line already ruled out for "2" by the 2 in the bottom line in top-left block. Therefore the two empty squares, top and middle horizontal lines, can be noted with small "2" each. Later on you go on to say "wherever possible", and you still did not see this. Oops!
Right. it is easy to miss. However in the end the puzzles was solved.
10:33 Dealing with "6's". You can put in "6" in bottom line (middle cell) left and right cells, as you have top line ruled out by the "6" in middle right block, and the entire dead centre column has a "6" in it already. And you would have to remove the "6" from the pair in bottom line of block on left hand side (in middle, vertically). That would place "5" in bottom row, left column, centre left block. Therefore, "5" being used, top cell becomes "7". Left Column, middle cell becomes "7". And in your next move about "7's", that eliminates "7" from middle block, top centre cell (where you have little "37") , leaving "7" to go in dead centre cell of that block. Oops. Big Oops.
Well done.. there are many ways to cook and egg. Thanks for your comment.

Love you Daddo but, please try to stand to the side and not cover up the board. Sometimes I need to see the whole board. Thanks, you're the best.
Sorry about that My recent videos are much better re your comment. thanks for your support.
Robin ..........I spotted 3T formations on the puzzle i am a currently on yet there are 3 numbers to fit into the puzzle, and one of the numbers is inside the very same block (different T )...........any tips on how we handle such?
HiJoseph. I suggest you send me the puzzle you are working on. Send it via my web site.

12:05 "3" in bottom centre block, top line, left and centre cells. Oops.
It's easy to miss. Yes. But it get solved in the end.
how did u get 13 14 34 sir....???
Prashant Velu Thank you for asking Prashant. This is not a real puzzle, I have just put those numbers to demonstrate what is meant by a 3X3. ie 3 numbers which can only go in 3 cells. You will discover many of these in rows, columns and blocks as you progress onto the more difficult puzzles.. It is a matter of spotting them and this take practise. Hang in there!
Prashant Velu III
realy thx but how can write in 2,14 sec 13,14,34 your logic ok or you can write becouse there is no restriction outside

In systematic horizontal/vertical set of blocks scanning "There is only one N , leave it" is a misleading guideline alone, it is not a sufficient reason for there not being new numbers to be spotted, it gives rise to too many missed opportunities, as you could use 'cross technique' (or perhaps some others) to eliminate cells, and establish new final numbers or mere candidates, in some rare cases even when there are no Ns. I am surprised that you don't apply 'cross technique' here as in other lectures (several double candidates and at least one final number are missed here). Or perhaps you just wanted move along faster to the core teaching of the video, or for a similar reason.
When you say "Too much information" in 10:30 on, strictly speaking should not the correct expression be "Not enough information": the more semantical information we gain, the more impossible or uncertain cases, here cells, are being ruled out, that is, by narrowing down our search space of cells, our uncertainty decreases, hence more informed we become.
Thank you for the videos (and sorry about the rant but "There is only one N , leave it" is not a good advice).
You are right. Please undestand that there are many paths to take to solve. In this case my main aim was to show the 3X3 pattern which is essential to know about.
very good but ur blocking it
Sorry!
