Hi Mr. Jarman! I was in your grade 5 class at Lakeview Elementary many years ago. I have so many fond memories of my time in your class. I am a teacher now myself.

Nice video. I would suggest spending a lot more time explaining what is going on with the XY chain since that was really the crux of the whole solve. Most of the rest of the video is just tidying up pencil marks, but you glossed over completely why the chain even works at all. That would have helped your viewers a lot.
Around 2005-06 I was so addicted to Sudoku that I would go to coffee shops and rip the Sudoku page off of newspapers. Still love it today. Good for the brain.

Great as usual. At 31:30 the 4 that was removed in the top middle box by using the 6 9 two answers to the puzzle, you could always use the triple in the same column (column 5) to get rid of the 4 at the top. Or even notice that there is a hidden matching 6 9 in the same column. Possible these are easier to spot.

Good Point. There are times when a strong link can be used. (not often) This puzzle was tough as you can see later. It can be solved. Try solving it without using the strong and weak links section. Robin
@11:30 I thought you were excited as marking the little 9’s in block 7 would give you the big 9 in block 9 which as collateral would give you the 9 in block 3 so when you placed the little 9’s to make the matching pair in block 8 I was really confused and thought why couldn’t they go in the top row😂 had to replay to hear you explain the reason why and it’s logic I had never thought of before so simple yet so effective wow will be looking out for that in future games thank you amazing video as per 👍🏼

Congratulations. Often there is more than one way to go....so much depends on what you see and when. However a step by step procedure is also very helpful Robin
At approx 16:30 into your video you pencil 2 in r3c4 and r3c6. I did not see why you were able to eliminate the 2 for possible in r2c4 and r2c6. Please explain why at that point of the puzzle that 2 is not possible in r2c4 and r2c6. Thanks. It seems at approx 23:00 into video you correct that omission when you enter all the missing small number possibilities. My final breakthrough also came using a XY chain, but interestingly it involved a different set of numbers. Amazing how solutions can be arrived at using different directions. Thanks for the difficult puzzle. I enjoyed it a lot.
I made the puzzle by myself and got stuck where you solved by using the x and y chain and pivot technique. . That part I still did not get. I have to check out more of your videos on this…great video!

What I like to do too is, see the second last row of numbers, they are 4 _ 1 _ 2 _ 5 7 8. Since there are 3 remaining spaces I write outside the box each of the 3 possible combinations, in this case 3 6 9 remain Then I write 369, 396, 639, 693, 936, 963 and look up and down each row to see, by chance, if there are any of those numbers in their place. Since there is a big 9 in the top cell, you immediately eliminate the 936, 963 combinations so now you have 4 possible combinations remaining 369, 396, 639, 693. It's a long way around doing it, but if you like it, you like it 😅😃
It was an extremely important puzzle for serious learners like me. I think it would have been easier for us to understand XY chain if the small digits were marked as follows: ab, bc, cd, da -representing 12, 23, 35,51 to eliminate #1 from r1c1. Regarding AIC of #2 the weaklink in Box#1from #2 to #2 was a strong link behaving as a weaklink where the definition of a Weaklink " if A is true, then B is false" is satisfied.
A very interesting puzzle. @36:00 The XY chain was a very good find. But I interpreted it a bit different. I looked at the 23 pair in box 6 (R4C7) and looked what the effect would be if I put a 2 or a 3 in it. As I followed the chain I then came to the conclusion that the 12 pair in R1C7 could only be a 1. This then allowed to solve the rest of the puzzle quite easy following the pencil marks.

Using the fact that we know a sudoku has a unique solution to reduce options by spotting potential deadly patterns requires us to step outside the inherent logic of the puzzle and apply the meta-logic of the fact we have been told the information it has a unique solution. This doesn’t seem to be a particularly “pure” technique, although of course it does work due to the information we have about the sudoku. But a well-constructed sudoku ought to be soluble without needing to resort to such means.
I column 6 cell 3 and 6 are the only places in the column where you find a 3/8. Therefore they become a matching pair. and other small numbers in those cells can be removed. Please watch this section again and I hope you will understand. All the best Robin
I suggest you look at tutorial 69 and above as I cover a lot of information about locked little numbers. Removing of 4 in row 1 cell 4 .It could have been done when I noticed the locked little numbers (4) In block 8 which meant that the little 4 in row 1 could be removed. because there had to be a 4 in column 5 block 8. Thanks for asking. Robin

This is such a huge leap up in difficulty compared to almost all of your other videos, that I fear you will have successfully alienated 98% of your audience. I may be wrong; time will tell. I used a sort of chain in the left-most vertical chute to crack the puzzle. A 5 in R4C1 soon led to a conflict, as it left no space for a 2 in box 1.

Hello hello hello. Thank you so much for your support. Please tell your friends about my site Robin
Around 2005-06 I was so addicted to Sudoku that I would go to coffee shops and rip the Sudoku page off of newspapers. Still love it today. Good for the brain.
Yes and good for memory. Thanks for your support Arctic.Wanderer
Done, waiting for tutorial 100 , century awaited
Tutorial 100 is coming out in February. It is a unique tutorial as it has my wonderful partner Cathryn working with me. My special guest.
Hello, sir.

Hello! I love Sudoku. Thanks for your tutorials.
Speaking of 'not so easy puzzles'...how about those where hardly any numbers are provided? Will you demo how to solve them? Thanks!
Great suggestion! If you go to my sudokuguy.com you will see a list of all the videos starting very easy to very hard. I would suggest that you look at this page and learn by going step-by-step. Thank you for your support. Robin
Great as usual. At 31:30 the 4 that was removed in the top middle box by using the 6 9 two answers to the puzzle, you could always use the triple in the same column (column 5) to get rid of the 4 at the top. Or even notice that there is a hidden matching 6 9 in the same column. Possible these are easier to spot.
Great job! there are many times where you miss ramifications and sometimes as a result new techniques can be used.
If you’re wondering if there are any 2’s in the middle block of rows, here is the answer: 04:22
Sorry there is and if you watch further a 2 comes up Notice that I use a procedure to go through the puzzle. I suggest you go below and click on the link to learn more.

At 34:06, why are the [2s] in box 1, regarded as a weak link when there are only 2 options in box 1 for the 2 to go into, wouldn't that be a strong link???
Good Point. There are times when a strong link can be used. (not often) This puzzle was tough as you can see later. It can be solved. Try solving it without using the strong and weak links section. Robin
Fan of your videos, you make me to understand this game easily which i thought very tough in childhood. Super work sir, love from India😊👌

Always a joy to watch. Thank you.
Thank you so much
@11:30 I thought you were excited as marking the little 9’s in block 7 would give you the big 9 in block 9 which as collateral would give you the 9 in block 3 so when you placed the little 9’s to make the matching pair in block 8 I was really confused and thought why couldn’t they go in the top row😂 had to replay to hear you explain the reason why and it’s logic I had never thought of before so simple yet so effective wow will be looking out for that in future games thank you amazing video as per 👍🏼

This was a tough one, I was right with you until about minute 33, then raised column 5 could only be 1 & 4 in bottom square, and from there finished the rest of the puzzle in about 3 minutes.
Well done 😀 thank you so much for your support

another great video Robin😀
Thank you so much 😀 please tell your friends.
23:04 I found X-wing with 5s in left blocks, that solved the whole puzzle.
Congratulations. Often there is more than one way to go....so much depends on what you see and when. However a step by step procedure is also very helpful Robin
Its hard for me to spot x wing 🍗
At approx 16:30 into your video you pencil 2 in r3c4 and r3c6. I did not see why you were able to eliminate the 2 for possible in r2c4 and r2c6. Please explain why at that point of the puzzle that 2 is not possible in r2c4 and r2c6. Thanks. It seems at approx 23:00 into video you correct that omission when you enter all the missing small number possibilities.
My final breakthrough also came using a XY chain, but interestingly it involved a different set of numbers. Amazing how solutions can be arrived at using different directions. Thanks for the difficult puzzle. I enjoyed it a lot.
thanks for sharing Really appreciate it.
I made the puzzle by myself and got stuck where you solved by using the x and y chain and pivot technique. . That part I still did not get. I have to check out more of your videos on this…great video!
Glad it helped! hang in there You can do it. I demonstrate this in a puzzles somewhere between tutorial 75 and above
Thank you Robin.😊

What I like to do too is, see the second last row of numbers, they are 4 _ 1 _ 2 _ 5 7 8. Since there are 3 remaining spaces I write outside the box each of the 3 possible combinations, in this case 3 6 9 remain
Then I write 369, 396, 639, 693, 936, 963 and look up and down each row to see, by chance, if there are any of those numbers in their place. Since there is a big 9 in the top cell, you immediately eliminate the 936, 963 combinations so now you have 4 possible combinations remaining 369, 396, 639, 693. It's a long way around doing it, but if you like it, you like it 😅😃
Thank you very much for your comment. If it works for you that’s fantastic. Robin
Please,make a video about how to solve number of pyramid.🙏🙏🙏🙏🙏🙏😥😥
Sorry I am not familiar with pyramid. Send me a picture of one please. You can email me at support@sudokuguy.com
It was an extremely important puzzle for serious learners like me.
I think it would have been easier for us to understand XY chain if the small digits were marked as follows:
ab, bc, cd, da -representing 12, 23, 35,51 to eliminate #1 from r1c1.
Regarding AIC of #2 the weaklink in Box#1from #2 to #2 was a strong link behaving as a weaklink where the definition of a Weaklink " if A is true, then B is false" is satisfied.
Thanks for your reply and yes you are right.
A very interesting puzzle. @36:00 The XY chain was a very good find. But I interpreted it a bit different. I looked at the 23 pair in box 6 (R4C7) and looked what the effect would be if I put a 2 or a 3 in it. As I followed the chain I then came to the conclusion that the 12 pair in R1C7 could only be a 1. This then allowed to solve the rest of the puzzle quite easy following the pencil marks.

Love your videos, they are great teaching tools. Here is something that puzzled me though. At 16:40 you put little 2's in row 3 columns 4 and 6. Seems like the 2's could also have gone in the same columns of row 2? Did I miss something?

Using the fact that we know a sudoku has a unique solution to reduce options by spotting potential deadly patterns requires us to step outside the inherent logic of the puzzle and apply the meta-logic of the fact we have been told the information it has a unique solution. This doesn’t seem to be a particularly “pure” technique, although of course it does work due to the information we have about the sudoku. But a well-constructed sudoku ought to be soluble without needing to resort to such means.
Right ... thanks for your comment.
At 27 -27 min say3/8 hidden matching pair you didn't say why I rubbed out the two can you or some one explain please?thank you
I column 6 cell 3 and 6 are the only places in the column where you find a 3/8. Therefore they become a matching pair. and other small numbers in those cells can be removed. Please watch this section again and I hope you will understand. All the best Robin
don´t get it 32:25, the elimination of 4 column 5, row 7. thanks for the further explanation.
I suggest you look at tutorial 69 and above as I cover a lot of information about locked little numbers. Removing of 4 in row 1 cell 4 .It could have been done when I noticed the locked little numbers (4) In block 8 which meant that the little 4 in row 1 could be removed. because there had to be a 4 in column 5 block 8. Thanks for asking. Robin
Can u solve one of the hardest Sudoku that exists ? I want to see u trying in a video!😃
Send it to me and I will get back to you as soon as I have time
I suggest you look at tutorials number 79 to 99. There is much to learn about hard puzzles in this set of tutorials.
I listen to your videos with headphones and I hear the wind going through your home. Sounds haunted. 🙂
Sorry that day was very windy.
At #10, you could have also used the 134 triple in column 5 to eliminate the 4's in rows 1 and 5.
Hello java, Sorry but i don't see a 134 triple in column 5.
After your video #100 I could not find further videos.
Sorry but I have sickness in the family which has taken up a lot of my time. I am assuming you have watch all of my videos e.g. Tutorials from 1 to 100 . If so congratulations.

Q: at timestamp 35.40 you mentioned you were employing an X-chain technique. Ive watched ALL your videos, I dont ever recall an X-chain, particularly being shown. I’ll have to go back through your catalog. Do you recall which video it was in? Thank you this was a great video.

I don’t know if anyone understood what you were doing with the coloured pens. There was not an explanation
When a new number is solved I used a different colour so you know what is not in the original puzzle. Hope this helps.

At 27.01I was right 38
Thanks
I dont know why you eliminated the 4 on minute 31
Good Question This was the only way of stopping the "danger danger" of having 2 possible answers. This puzzle was a difficult puzzle. Well done for getting this far on your learning curve. Robin
That second or "XY chain" was impossible for me to see or understand.
Yes the XY chain is difficult to spot. For more information about the power of strong and weak links, see below the video. I give a list for you to study. Strong and weak links are used in several of my videos Thanks for your question. You are the first to ask about this out of over 15 million viewers. All the best as you look at the samples I give below the video. #99. If you go to my channel page and look for tutorials 50 and above you will come a ross more examples of the XY wing. Robin

At 29.30 ur 5 is not deleted😂
Really See previous comments.
This is such a huge leap up in difficulty compared to almost all of your other videos, that I fear you will have successfully alienated 98% of your audience. I may be wrong; time will tell. I used a sort of chain in the left-most vertical chute to crack the puzzle. A 5 in R4C1 soon led to a conflict, as it left no space for a 2 in box 1.

Can't believe these sudoku tutorials. What is there to learn? Every booklet has instruction which takes about minute or two to read and that is it. Suguru is much more interesting and based on logic.
