Tutorial #43 The XY Wing Part 1

[@walrusahoy5878]

I struggled with the written logic of this until this chap talked it through. The pivot is where you apply the logic and not the pincers. Another sub for you!

[@SudokuGuy]

thanks Walrus.

​@@SudokuGuy, you must be superfast at advance level Sudoku. I love trying to best my own time score. Thank you for sharing your clever techniques.

[@SudokuGuy]

Hi all. I apologize for omitting an elimination at 4.50 of the small number 1 in block 3 cell 2. which left a big 7.

[@junkmailfolder5600]

Hello 🙂 I noticed a lot of confusion in the comments. It would be beneficial to pin a comment to the top which clears up the 1 in row 1 which may be eliminated is in column 8, not in column 4 as illustrated.

[@NatiDeNut]

4:50 - there is one cell you eliminated 1 from which I cannot see why (row 4 column 1). It is not 'seen' by both pincers, like the other two cells in that section.

[@SudokuGuy]

The pivot can "see" both cells. That is the key. I hope I have answered your question.

[@bmacdonald5137]

In your final example, the XY-Wing does not prove that the 1 in R1C4 is False.

[@SudokuGuy]

You are right. I should have mentioned this. Thanks for your feedback.

[@SudokuGuy]

I have made some improvements on the XY wing in the next tutorial.

[@commentfreely5443]

wow

[@Anione111]

@@SudokuGuy Could you not add an addendum to the video? I am confused now as to what actually can be concluded from the XY wing in the second example.

[@DocSardo]

@@Anione111 I guess the easiest way to think about it is that in order to be able to eliminate a number the cell must be able to "see" both X and Y, and must contain the number that is common to both X and Y (1 in this case). Only the cells R2C4 and R2C5 can "see" both X (same block) and Y (same row), so the "1" can be eliminated from both of those cells. Since the cell in R1C4 can only see X, but has no relationship with Y, the 1 can't be eliminated from that cell.

How to know which pair to take as a pivot

By looking at the numbers in the pincers and checking whether another cell can see both ends of the pincers. If it can then it can be removed. The little numbers are always a 3X3 3 cells can each be one of the numbers only.

[@gyongyipedersen9264]

But I could not understand how to identify the pivot?

[@SudokuGuy]

Yes a pivot is hard to spot. Look for a 3 cells with only 3 numbers which is called a 3X3 or Triplet. The pivot has 2 little numbers. If there is a cell which can see the pincers This is what you are looking for. if one of the numbers in the pivot is true then one of the pincers cannot be true. Same with the other number in the pivot. The cell which can see both ends of the pivot cannot be that number in the pincer. I demonstrate this better in a later tutorial. Hope this helps. Hang in there. the XY wing is difficult to find but always valuable.

[@InGreed666]

How do you find out which one the pivot is?

[@SudokuGuy]

Good question. imagine that the pivot is the centre of a clock and the pincers become the end of the hour hand and the minute hand.

[@kishoregupta1166]

In the XY wing how to identify Pivot and Pincers? A pincer can become Pivot also.. For example take three cells having candidates 27, 17 and 12. If I take 27 as Pivot then, 17 and 12 are Pincers. But if I assume 17 as Pivot then 27 ,12 are pincers. Or if I assume 12 as Pivot then 27,17 are Pincers? So which is correct? What is the logic to identify correct Pivot in XY wing?

It can "see" the other 2 cells. One in the block and the other along the row.

[@alinefuga5887]

I have a doubt . If the pivot is 4 then x=1 and the square on the right of the pivot cannot be 1 , so y must be 1 but if y=1 there is no 5 on that big square! Am I right or I’m missing something?

New to Sudoku....Please could you clarify if for me -- before applying the XY wing technique...do we need to establish that the numbers in the pivot and X and Y cells are the only possible numbers that could go into the cells?

No there can be other numbers. I use only one number to show easily the effect. I have another tutorial coming which shows how even having other numbers in the X Y cells can make a big difference.

Doesn't it take much time to write possible numbers in all boxes? But your method of teaching is very good.

[@SudokuGuy]

You are right. Avoid it if you can by using Snyder notation. However there are many puzzles where you have no alternative but to put all possible number in a cell. This is time consuming and messy. If this occurs look at tutorials from # 20 and up and you will see how to eliminate small numbers. Always use Snyder notation to begin with. i.e. never more that 2 small numbers in a cell.

[@dailydribble]

Newbie, so then what make it a "Pivot" ? seem you need to know how to locate it?

[@SudokuGuy]

A pivot is where if you use one little number it works and also if you use the other little numbers it works for each of the pincers.

Yes, I agree, it is easy to understand the logic, but what makes a "Pivot"? How can we be sure something is a pivot, and not pincer?

[@Jaiguruji77976]

This XY Wing is just like Hit and Trial method , if my understanding is correct..

[@SudokuGuy]

Hello Shweta. I am sorry but I don't agree. It is bases on logic. Please look at other tutorial where I cover this topic. go to my web site sudokuguy.com scroll down to the heading techniques and tricks and there you will see other videos where I talk about and demonstrate the XY wing.

[@amitpandya6827]

Nice, I still trying to understand

[@SudokuGuy]

Hang in there Amit. this is a pattern which is hard to spot.

[@MrChrisdube]

Thank you for the technique. However, I have a better question. Is there any resource for actually PRACTICING this technique? I first saw this about a year ago, but forgot how to do it because I haven't seen it since.

[@SudokuGuy]

You will only find this in advanced levels of puzzles. One thing I will say is this. the XY wing often will enable you to solve the rest of the puzzle. spotting them requires practice and patience. 3 cells with 2 small numbers with the numbers only being 3 different #. Happy spotting.

[@MrChrisdube]

@@SudokuGuy actually, because of its shape, I find it easy to spot. I just never see it anywhere. Same with X-wings. You mentioned Advanced resources. Can you recommend any in particular.

[@Audi-917P]

Love you sir....

[@SudokuGuy]

These are hard to spot. Usually found in difficult puzzles.

[@Audi-917P]

@@SudokuGuy yaaa..... i always had interest in sudoku but didn't know how to play..... I've learnt sudoku through your channel and thus started on my road of sudoku......... thank you very much sir..... love you Regards

[@atayaedreis1871]

thanks

You're welcome! Robin

[@lesliewendt648]

Finally!! I’ve been spotting those forever thinking “I know I should be able to use this, but I don’t know how!” Pretty soon I’ll be able to do the expert puzzles without the help of a hint (or three)! Thank you again! This and your previous posts have been very helpful.

[@SudokuGuy]

Glad I could help! Leslie. Love your sense of humor. You can succeed. Hang in there.

[@sylviacarlson3561]

So which number are you eliminating? You say "If" this number, then the result. I get that, but I want to see you do a puzzle where you locate the XY wing and then tell us what numbers should be eliminated. That would be very helpful.

[@SudokuGuy]

I will be doing these in real puzzles soon. I have a tutorial coming.demonstrating. To find them you require quite a few bivalue cells i.e. only 2 little numbers in a cell.

[@ohthatstoosalty3395]

Thank you, you explained it very clearly. I can't wait to use that technique!

How to solve or prepair a puzzle if all the cells are empty.

[@SudokuGuy]

This is not a puzzle but only a part of a puzzle.

[@sofiahedz]

Thank you!!!! :)

[@SudokuGuy]

You're welcome! Sofia. I suggest you look at Tutorial 44 as I did a better job with the explanation. Please give me a thumbs up below the video. if you liked it. kzbin.info

[@Darkhan9]

That doesn't seem right. In box 3, if the first number is 5, then the 5 gets eliminated from the y cell, making that a 1. That 1 eliminates in box 2 the 1s on the same line, but there can still be a 1 on the first line of box 2.

[@SudokuGuy]

Thanks for sharing.

[@bloodeyes1690]

I watch your videos and never do sudoku's its fun to watch surprisng how much detail people go into mastering them. Do you ever do timed solves or just difficult solves?

[@SudokuGuy]

I' m not into rushing. I like to take my time and I love a challenge. I do a puzzle every day while having breakfast and listening to the news. Sometimes on very difficult puzzles I will leave it and come back to it later. Often this helps me to see what I didn't before. It is amazing how this trick works. Please subscribe.. it's free and encourage others to do the same. Thanx!!
