[@dollarbill2208]

This was a great tutorial as far as the grouping zones organization. However, you only went through one type of W-Wing. The other type of W-Wing is where the matching pairs lie in different chutes, and there are only two possible cells for the candidate elimination. I would love to see if you could organize the other type of W-Wing in the zones like you did here, and showcase that one also. Edit: I see someone else has already brought this to your attention. Still very good insight though.

[@SudokuGuy]

Thanks greatly for your observation. I will seriously consider it soon.

[@csvidyasagar]

Dear Mr Robin, I have started solving Easy puzzles of Suduko after viewing all your videos of Beginner lessons, Advanced lessons and all 70 tutorials. I am 73 years old and slowly becoming addicted to Suduko, thanks to you. I have visited other videos on Suduko but I find none can explain Suduko concepts the way you do. Even most difficult concepts are explained in such a way a beginner like me understand without rewinding the video. Needless to say you are best in the business. You explain even complicated issues in a very simple language. I have one observation on W wing. In this video of W wing in Vertical Blocks, you mentioned that you do not take Matching pairs 6, 9 in cells Row 1 - Column 7 (R1 -C7) and R5 - C9. If I have heard you correctly, you say the Green Zone does not have digits of matching pairs. My observation is If you take 6 & 9 as matching pairs, then the Green Zone is in cells in Column 8 containing digits 5 & 9. Since matching pairs have digits 6 & 9, you can see Green zone has 9. Can you explain why you chose to take matching pair of 4, 8 as I have not understood why 6 & 9 cannot be taken as matching pairs? May be you might have solved using 6, 9 as matching pair and could not complete the puzzle. That I think could be the reason why you chose matching pair of 4, 8.

[@oldiesalternative5715]

@@SudokuGuy I agree with dan post & I still don't see how you can definitely eliminate the 8 in R9C1 (you say because there is an 8 in row 8 C1 but R8C1 is a 2)

[@scwyldspirit]

Robin, at 4:20 I was looking at R1C5 and that can't be a 2 or a 5 because of the 5 at R9C5 so now you are only left with a 2. Also you have a mistake if you go back and look at 12:07 if you look in lower left grid column 3 rows 7 and 8 it can't be a 7 or 4 because it would violate sedoku rules. because the 7 and 4 are already in C3R1 and C3R3 respectively.

[@SudokuGuy]

Right.

[@danpost5651]

@11:00 "Why can't this be an 8?" -- Truer words never spoken. Just because it didn't work out when you tried it one time, doesn't mean it won't work out the next time (just happened not to work that time).

[@SudokuGuy]

Thanks for your comment. hang in there. Nothing like practice to help you improve.

[@gabrielpoarch635]

How do you determine which matching pair to use? At 25:44 there is also a 1 and 7 pair that looks like it could apply to the W-wing. If it doesn't could you explain why it doesn't?

Yes you are right. congratulations. Tell me if the puzzles works out as I am travelling do not have the ability to do the complete puzzle.

[@fidsah]

On the last puzzle, if you execute a W wing on the 1/3 pairs in boxes 4 and 7, R4C3 becomes a 5. If, however, you execute the W wing on the 5/8 pairs in boxes 4 and 6, R4C3 becomes a 3. Since R4C3 cannot be both a 3 and a 5, I feel that there must be a more specific rule for identifying a proper W wing than this video went into.

[@SudokuGuy]

Interesting however both the 5 and 8 can go into the green zone. It is only a W wing when one of those numbers cannot go into the green zone. Hope this helps.

[@fidsah]

Can you also use an xyz wing? X being r2c6, y being r3c6, z being r2c1, to deduce r1c5 is a 2? With then makes r1c2 a 9, r3c1 a 5, and so on solving the puzzle?

[@svpickell]

this might be a silly question but why not just change the matching pairs to the number that has the number in the green zone? in the example above 58, 58 matching pairs and there is an 8 in the green zone so why not make the matching pairs 8's? thank you for your awesome videos!

[@SudokuGuy]

By all means you could do that. Because both numbers are in the green zone it is not a legitimate W wing.

As with most "Rules" this one is a combination of other "Rules" of Elimination by CoIncidence of Pairs. But the "Rule" is much more difficult to describe than it is to use. I can never remember the description or even what they are called.

[@SudokuGuy]

Thank you for your comment. I suggest you write the rules down somewhere. You are right....once you hae done a feww the rules are simple.

[@delmitch02]

Like to watch your series. I noticed in Tutorial #64 that when you show all the alternatives before doing the W wing you did not have an 8 in each of the bottom cells on the left side of the middle block or a 1 in the top of the bottom block in the middle top cell or a 3 in the top of the bottom middle block on the right side. If the 8"s were in then you do not have the the matching pairs that you selected so how can the puzzle progress?

@@SudokuGuy Oh I see now. I think you wanted to say red area in the video because if you start to use 69 as a w wing, you cant find any 6 in the red area so there is nothing there to eliminate. Right?

[@lauramcastro4897]

@@Sakraf654 I do think that's what he meant, yeah!

[@electroniceyes36]

i got that. bt i'm confused. i'll talk about the 1st example. there was a pair (2,5) in the position (row=1, column=5) or at the middle of 6 and 1 in the 2nd block. so in that position we have to put 2 or 5. now if we look down along the column there was a 5. so we can easily drop out 5 from the pair (2,5). then it becomes 2. another way we can also get the 2. that is, there was a matching pair (2,5) in the 1st and 2nd block.[ note: i really don't understand that why they are a matching pair. because i knew that the position of a matching pair can be in a row or a column or a block and if one of them is a certain number then the other will be distinct and corresponding number with respect to the pair. in these case (2,5) doesn’t not satisfy the rules]. and then and you showed that if one is 2 then another will be 2. but if one is 5 then it doesn't fit. so 5 can't be the answer. thus the answer is only 2. and the rest calculation is easy. so why do i use w-wing ?

I think I understand you however the 2/5 matching pair is the key for solving a W wing.

After reading all of the 3 years of comments, it appears I am the only one who wonders how the W-Wing got its name (or maybe the only one who cares?). I don't notice any visual clue in the puzzles you demonstrated. Also I searched several other sudoku sites to find out, but it isn't addressed anywhere I've looked. Is it an arbitrary letter assignment?

[@SudokuGuy]

I think so.

[@fernandoricagno]

hey ,,, Great Sudoku Guy ,,, I was reading all the comments and there is something I cannot find clearly , maybe is some restriction in the definition of W-wing Example 1 . Why isn't possible use MP 59 ? Ekample 2. Why isn't possible to use MP 47 ( blocks 1 and 2 ) and also MP 47 (blocks 2 and 3 ) Example 3 wht dont't use MP 69 Example 4 : why don't use MP89 ? Thanks a lot

[@prabhoochandshiboo8390]

In the first example if we take 59 as the matching pair it does not work ,why?

[@SudokuGuy]

god question. I did not cover the green zone being in the middle, however the principal still works. Using the big 9 is safer as we can't tell in the green zone whether there will be a big 5. due to 2,5,7 The blue zone is in 2 spots row 1 c4,5,6 and row 3 c 8,3,5/7., therefore the red zone is in row 1 bl1c 1,2 3 and row 3 bl 3.c 7,8,9, this means the 9 can be removed in block 1 c2 and block 3 cell 8.Using TMB and ram it is can be solved. such as you get a W wing. thanks for your question. I will add this to my description.

[@fernandoricagno]

@@SudokuGuychoosing MP 59 ,,,,,, as you said , you remove 9 in block 1 c2 and block 3 cell 8 . Using TMB then you arrived with two 5's in block 1 cell 4 and in block 3 cell 4 that's not possible. ?????

In this video, i feel you don't clearly illustrate why the green,red, and blue blocks are where they are.

[@SudokuGuy]

I suggest you look at this video again as I do explain the different colours. and where they may be found.

I don't understand why you decided to remove the two twos at the start. You could have just as easily removed the five and the nine from those two cells, and have gotten a different - yet still possible - solution. Also, I don't understand how you got your small numbers in the first place. You say 5 can't go in r3c8 in the first place. But what precludes it? There's no other 5 in row 3 or in square 3 excluding a 5 there. There isn't a cleaver pattern forcing the 5 up, there isn't a naked pair in the row or a matching pair in the square forcing it out, and we know there isn't a 5 in column 8, because you've put a small 5 in r1c8. So it makes no sense to me - how could you eliminate a 5 from that cell? Again, in the second example, I still don't follow the logic - you want to make one part of the pair an 8 because that would make the other an 8 also. But what you want and what you get aren't the same thing. You can just as easily not make one or the other an 8, and since you can do both, it means you have no proof to do either. Also, an 8 in cell r8c8 does not exclude an 8 from cell r9c2. It excludes an 8 from r9c8, which pushes the 8 in row 9 to square 7, meaning either cell r9c1 or r9c2. And nothing to indicate which one of the two get the 8. Essentially, you've explained what this W-Wing thing does, but never explained why. You say you've tried putting an 8 inn the other cell (r9c1) and then tried to complete the puzzle and it didn't work - well, great, that's bifurcation for you! But you're not doing bifurcation, you're teaching logic. So kindly please explain it.
