Excellent lesson. I have watched many sudoku tutorial and nobody taught this method. Your video are very well explained logically and very well demonstrated with visual cues.
Excellent video - I’ve watched this video three times over the past week and today I finally found and solved an xy wing. It feels great to have spotted an xy wing and worked out the logic. I have been struggling with the xy concept for sometime and this video make total sense to me. Thank you.
Excellent explanation. I see so many how-to's that show what to look for but don't explain the exclusion logic. This is a very powerful demonstration and learning tool. Thank you.
Fantastic explanation! This is a very difficult topic to explain with clarity and rarely does the light go on in my head, like it did when watching this video. Thank you very much!
Ahh thank you so much! I finially get it 🎉❤ Great multiple examples, that’s what helped me understand the formula. Thank you again! So satisfying to unlock the puzzle
At 1:05 a bunch of numbers magically disappear, (crucially, the 28 in row 2 column 6). Why is this? Is that part of the Y wing 'magic' or was that done by some other logic that I can't follow?
Detailed and well explained. Gives me confidence to tackle some of the more challenging puzzles I am getting. Thanks very much for all your sudoku puzzles guides!
I copied this puzzle a couple of months ago, stowed it away, and tried to solve it on my own this morning. I found a different y wing: cells 41, 63 (pivot) and 69 which combined eliminate the 469 in cell 61, leaving a 3 for that cell. Maybe technically it's not a y wing but I think it works.
Not following very well, but definitely do a spot check now with the XY and it helps identifies the single # that goes in the box. I use probabilities which work only 90% of the time, though
For example 1 - I don't see how this is a y-wing. Both of the wing cells have only two candidates, yes, but BOTH candidates in each of the wing cells are also in the pivot cell. That is until at 1:05 two candidates in the pivot cell magically disappear to make the pattern fit the definition. How did you know which of the 4 original candidates in the pivot cell to eliminate?
ok, i am seriously still stumped, like aimlessly stuck. I take pride in my math skills and have done well in my career as a result, but unfortunately still cant grasp it. if u have time can u help me, plz
I’ve got a puzzle with what appears to be an XY wing but it seems to cancel out the correct answer. I’d love to show this puzzle to someone who could help!
if thats xy wing there is another one with the 79 in the middle box aka box 5, one wing is in box 2 contains 47 and the other wing is in the box 4 and contains 49, either way both box 2 and 4 could have number 4 but that solves nothing i wonder is it xy wing at all or it is but its just unusable xy wing someone ?
Actually, if you follow the Sudoku logic the 7 in the 79 also sees, or is the same as, the 9 in the 49 in Row 1 Column 3. 7 eliminates the 7 from the 47; leaving 4 which reduces 24 to 2; creating a 34 pair eliminating the 4 from the 49. Leaving 9. Does that make sense? Thanks.
This solution violates the multiple solutions rule. When you lay the 8 you end up with 4 intersecting cells with the candidates 2/8... Unless there's an error somewhere else. Cells in question are A4, A9, H4 and H9
0:33 Instead of relying on Google first-page response, in the future how about curating/picking a clearer definition? Because Google's was awful. "unit".... okayyyy, what a uselessly broad term. Ugh. And how does it define "first"? It doesn't. If you're going to try to teach you have to use well-thought out materials that are appropriate to beginners. I think your videos have merit, but teaching is a skill that requires effort to think llike someone who knows little/nothing of the topic you are trying to teach. At 1:02 we see 6,B lose two candidates without explanation. You never explain HOW you spot an X/Y wing, they're just magically green now. Nor do you explain why that is the "pivot" cell (we have to guess it's related to intersection). Again, I think your vids have merit, but you need to proceed from the standpoint that the viewer does not know what you know.

When the XY is shown to me, it becomes obvious. However, the odd of me finding one in the wild are slim to none!
Согласен на 100%! Быстрее банальным перебором решить судоку, чем искать (и не найти) необходимые пары. 😏
I'm having trouble identifying the pivot..
😅😅
Excellent lesson. I have watched many sudoku tutorial and nobody taught this method. Your video are very well explained logically and very well demonstrated with visual cues.
Thanks mam, and please never stop. Your Sudoku tutorials are top-notch.
This is by far the best and most detailed explanation that I've heard. Such a good explanation that is clear. Thank you so much!!
For quite a while I have been trying to spot and figure out the xy wing. This video is the best explanation that I have found! Thanks!!
Your instructional technique is excellent!
best explanation of the XY Wing I've come across. Thanks!

Great Lesson. XY wings are very hard to find (for me anyway). I enjoyed your explanation.
Excellent presentation. Spot on explanation...simple, elegant, easy to understand!
This really is the best explanation I've seen, love the multiple examples
Very clear explanation, with different examples. Thanks to you, i've got it at last! Many thanks.
Great explanation. Thank you. Cleared my doubts on XY wings
This is best XY Wing example ever! I can actually do them now. Thank you!
Fantastic explanation! This is a very difficult topic to explain with clarity and rarely does the light go on in my head, like it did when watching this video. Thank you very much!
This is the best explanation I've come across! Thanks!
Such great explanation, examples and practice! Really, really clear to understand. Thanks a lot!!!
This was so helpful. Thank you. I’ve watched other videos but never really got it before!
Thank you so much. I don't think I have found anyone that has explained as well as you have so I subscribed
Ahh thank you so much! I finially get it 🎉❤ Great multiple examples, that’s what helped me understand the formula. Thank you again! So satisfying to unlock the puzzle
I’ve been confusing y wings with swordfish. Your explanations are helping me so much!
best explanation of the XY Wing Thanks
This looks like a powerful tool, very well explained by you, thank you. However, one needs practice in spotting the 3 cells.
Great tutorial!
Great job explaining it! Thank you!
Thank YOU, I appreciate your comment!
Great explanation! Thanks!
At 1:05 a bunch of numbers magically disappear, (crucially, the 28 in row 2 column 6). Why is this? Is that part of the Y wing 'magic' or was that done by some other logic that I can't follow?
it was magic
A Wonderful explanation. Thank You.
Thank you so much!❤ This was a very well explained video❤
OMG u r so amazing!!!!!!!!! Thank you for sharing this info!!
Detailed and well explained. Gives me confidence to tackle some of the more challenging puzzles I am getting.

Thanks for the comment kolst8406! Whatever works, right? There's more than one way to solve most any puzzle. Have a great day!
Not following very well, but definitely do a spot check now with the XY and it helps identifies the single # that goes in the box. I use probabilities which work only 90% of the time, though
Very good explanation thank u so much mam
How did the pivot cell jump from being 2368 to just 68 with no explanation?
That's the exact place where I get confused, too.
Thanks a lot very nice video
It is hard to find them. First i try to see the "bent triple" . And if i found one ,then i try to make the XY-wing.
For example 1 - I don't see how this is a y-wing. Both of the wing cells have only two candidates, yes, but BOTH candidates in each of the wing cells are also in the pivot cell. That is until at 1:05 two candidates in the pivot cell magically disappear to make the pattern fit the definition. How did you know which of the 4 original candidates in the pivot cell to eliminate?
Thank you!!!
My pleasure, and thank you for watching!
Hi, in the 3td example, i was looking at A4(69), C6(49) pivot cell and I6(46). Is it another posible XY wing? Please advise. Thank you
Can the pivot cell and the wings cells be in the same row??
I love your easy learn way of explaining sodoku but canwe solve a sodoku puzzle without having to rely on x wings orxy wings
很棒喔👍
excellent
In block 5 cell 7,8 also is peer cell
Isn't it Mam In the third example
ok, i am seriously still stumped, like aimlessly stuck. I take pride in my math skills and have done well in my career as a result, but unfortunately still cant grasp it. if u have time can u help me, plz
It looks to me that any of the three cells can be considered pivot cell while the other two wings, right?
I was thinking the same thing.
I’ve got a puzzle with what appears to be an XY wing but it seems to cancel out the correct answer. I’d love to show this puzzle to someone who could help!
if thats xy wing there is another one with the 79 in the middle box aka box 5, one wing is in box 2 contains 47 and the other wing is in the box 4 and contains 49, either way both box 2 and 4 could have number 4 but that solves nothing

someone ?

nice
Idk why , when I find one I always have to different numbers and she always get 2 of the same .
2nd example was not needed as we had a 1,5 double which would have left a naked 7 and a naked 8 which would have solved it a lot quicker.
I watched on my mobile and simply couldn't see the numbers.
When you say the answer I see the solution as clear as day and understand until I get another example. Idk, maybe I need Jesus to help me every time.
It seems that the so called pivot can be any of the three cells
well yes thats easy theres only a few numbers missing try that with an extremly hard one at beggining
XY wing, Y wing, whatever, it looks like an L to me

I don't understand this at all
1:53 Seriously? SERIOUSLY? That's your explanation for the naming? Seriously thinking about unsubscribing.
