Hello dear mentor, I have been playing sudoku for a while and enjoy so much! I never searched for tips and tutorials since starting playing but came across your videos and have been learning so much from you plus I admire your patience and personality teaching your subscribers. I watched all your videos all the way to tutorial number 100! I love when you say “what’s the ramifications of that?” and keep saying to myself the same thing while I’m playing. 😂 I noticed you replied to one of the comments that you are taking your time to focus on your family health and I admire that. Hope you and your family are doing well and wish you a speedy recovery. In other words come back we need you!

First of all I would like to say: I love your channel! What I haven't understood yet: when do I know that I should look for an x-wing... It's pretty time consuming. Love from Munich
Good question! when you find a small number in the same row or column which is in diffent blocks. Once you find this then look for the same making a rectangle in another row or column. I suggest you look at the tutorials 63 and 63 .again. You will notice that in one case I dscovered an Xwing using rows and in the other I discovered an X wing using columns. Hope this helps.

Hello RObin , your explanation is GREAT . And I understood finally the x-wing . but maybe you should reinforce that in the columns should only exist 2 small sevens . That was my error until I understood your clear definition of an X-wing .Congrats

At 4:08 there is something nice to spot after putting the 2 little 7s in box 2. Because of the 7s in c1 and c9, putting a 7 in C5R2 impose the 7s in box 7 and 9 to be on the same row (R9). Impossible. So 7 in box 2 is in C5R3. Which gives the 3 and then th 6 in box 2, then all the 8s in the grid...
I get stuck sometimes, usually near the end, where the x,y,z, wings don't work. (Wings have been really helpful.) Can you suggest a trick that might work. It happens fairly often, and I just have to finish by trial and error. I think it has to do with isolating a number that can only have on possibility. (a pair of numbers included on a possible "wing" set, but not associated with the wing.) I hope this makes sense.
Sorry Charles I am a little confused. With the X wing you are looking for a rectangle using usually iwith the corners in 4 blocks. where one number is found only twice in a row or column and in 2 blockes. Hang in there..Sometimes looking at a video again helps
Very good instructions. All of the examples in 62 and 63 look like the numbers are in both the rows and columns at the same time. How do you tell if the x wing is in the row or column?
It is either in a row or a column Either the row or column will only have the number 2X Check this out if you wish. Thanks for your comment.

I agree with being sparing on the Candidates because they clutter up the space. Generally speaking for me when candidate are in a line within a cell I put all three in but only two if they are not. The line eliminates for the other cells in line with them. I had a collegue who never put any candidates in, phenonimal memory.

#SudokuGuy What would you suggest for a puzzle that has all 4 of the corner grids completely blank? It is in the middle of a Samuari Sudoku Puzzle. It is the 9x9 grid that connects to the other 4 outside grids....

@@SudokuGuy I'm finding that working with the 9x9 grid in the middle of the main puzzle that has all the corner grids blank it is a little easier to try to fill those empty grids in if I get most of the middle grids figured out.
Hello, thanks for this tutorial. I've searched this question on the net but haven't yet found anything. Once you have all remaining squares with only two number (so not a BUG+1) where do you go from there?
Hello Barb Well having not seen what you have I am guessing that there are or is a matching pair there or there are no matching pairs!!! Whatever it is , maybe send me your puzzle that you have almost completed and I will have a look at it. You can send me your almost completed puzzle by going to sudokuguy.com. Scroll down to where you can send me an email and a copy of your puzzle. Robin
Question please: Thanks for all you videos Robin ... For me, it spoils a puzzle when I have to revert to a 50:50 choice and then trial and error to see if it works out or not later on the the puzzle... Is it possible to solve all Sudokos without trail and error with 50/50 cells? Or do some puzzles force the trial and error approach?
Good question My tutorial in July soon to be uploaded. I mention this. Look at my tutorial # 21 Danger Danger. I only use this when I am in a hurry and want complete. The logic is " if not this then it MUST be that" providing you have all the correct small numbers. Keeping an eye out for a danger danger is important, however when I see a potential danger danger I always try to solve it anothe way using logic.

I printed the puzzles I'm working on from www.memory-improvement-tips.com/printable-sudoku-puzzles.html. I chose very hard. I did the easy and hard (from another site). These are TOUGH. I'll watch your other lessons. Thanks.
Im literally sitting here crying. I thought i had it, 2nd C & 7th C top row and 8th row 2nd column and 7th. Whoa..... watching you work the puzzle mine was an x wing also I think? If not, I will be diving so deep in x wings as i feel like i am drowning anyway. Autism brain stinks. 😭😣😓😩
HI Kandi sometimes it takes watching a video more than once. There are 2 types of X wings one is using rows and the other is using columns Maybe you have watched tutorial # 63 already. Hang in there ....once you understand the steps you will succeed. it takes practice spotting X wings.
@@SudokuGuy Yes Thank you so much. I did watch 63 also. I do rewind and rewatch the parts my brain won't compute and it does help. I keep a small file box near me and one folder is puzzles to come back to, IE: called "stepped away" and after several months of watching your videos I was able to pull them all out and solved them all except one like it was my job. 😊 so i am definitely learning, just not as fast as I would like.

This formula determines if “1” is a candidate in column 1 row 1. Candidate is defined as a number that does not already exist in the Column, Row or Box. There are 729 formulas like this naming different parameters. The formula considers the influencing cells. The “&’s” concatenate the influencing cell values. The FIND searches the concatenated string for a number, in this case “1”. If “1” is not found then it is a candidate. Writing the formula is tedious. There is a pattern which makes it possible to automate the formula writing…more fun.

Thanks a lot for helpful tutorial. I am watching from Brazil.
Glad it was helpful! Thanks for your support. Robin
Agree with other comments that this was the best explanation of how to work out when a X wing is present
Thanks Please tell your friends. and thanks for your support. Robin
Hello dear mentor,
I have been playing sudoku for a while and enjoy so much!
I never searched for tips and tutorials since starting playing but came across your videos and have been learning so much from you plus I admire your patience and personality teaching your subscribers.
I watched all your videos all the way to tutorial number 100!
I love when you say “what’s the ramifications of that?” and keep saying to myself the same thing while I’m playing. 😂
I noticed you replied to one of the comments that you are taking your time to focus on your family health and I admire that.
Hope you and your family are doing well and wish you a speedy recovery.
In other words come back we need you!
Thanks for your your kind remarks. I hope to continue soon.
Your sudoku lessons are the best. Thanks for your help only I have done the sudoku champ and won. Love from India

First of all I would like to say: I love your channel! What I haven't understood yet: when do I know that I should look for an x-wing...
It's pretty time consuming.
Love from Munich
Good question! when you find a small number in the same row or column which is in diffent blocks. Once you find this then look for the same making a rectangle in another row or column. I suggest you look at the tutorials 63 and 63 .again. You will notice that in one case I dscovered an Xwing using rows and in the other I discovered an X wing using columns. Hope this helps.

Excellent sir… locating x ( 7 )wing is great…👏👏👍👍
Spotting x wings takes practice. You can do it Avanda
Hello RObin , your explanation is GREAT . And I understood finally the x-wing . but maybe you should reinforce that in the columns should only exist 2 small sevens . That was my error until I understood your clear definition of an X-wing .Congrats
Great suggestion! Fernando. Hang in there. there are 2 examples of an x wing.. I hope you looked at both.

At 4:08 there is something nice to spot after putting the 2 little 7s in box 2. Because of the 7s in c1 and c9, putting a 7 in C5R2 impose the 7s in box 7 and 9 to be on the same row (R9). Impossible. So 7 in box 2 is in C5R3. Which gives the 3 and then th 6 in box 2, then all the 8s in the grid...
Great thanks for sharing. there are many paths to take in sudoku. In this tutorials I was more interested in how to spot and Xwing.
Thank you for your xyz techniques
Sorry x techniques
Glad you like them! Have fun looking for them.
@5:23 The magic 1,3 pair puts directly a 4 in the middle right cell of the bottom-right box.
Yes you are right. I left as i was wanting to show a technique later for beginners.
@@SudokuGuy Understood. Thanks for the ramification of the X-wing. In this Sodoku it is the crucial step to be able to continue.
I get stuck sometimes, usually near the end, where the x,y,z, wings don't work. (Wings have been really helpful.) Can you suggest a trick that might work. It happens fairly often, and I just have to finish by trial and error. I think it has to do with isolating a number that can only have on possibility. (a pair of numbers included on a possible "wing" set, but not associated with the wing.) I hope this makes sense.
Sorry Charles I am a little confused. With the X wing you are looking for a rectangle using usually iwith the corners in 4 blocks. where one number is found only twice in a row or column and in 2 blockes. Hang in there..Sometimes looking at a video again helps
Very good instructions. All of the examples in 62 and 63 look like the numbers are in both the rows and columns at the same time. How do you tell if the x wing is in the row or column?
It is either in a row or a column Either the row or column will only have the number 2X Check this out if you wish. Thanks for your comment.

I agree with being sparing on the Candidates because they clutter up the space. Generally speaking for me when candidate are in a line within a cell I put all three in but only two if they are not. The line eliminates for the other cells in line with them.
I had a collegue who never put any candidates in, phenonimal memory.
Hi James. Yes they either have a great memory or the puzzles is not very diffcult even although the category may be hard or above.

#SudokuGuy What would you suggest for a puzzle that has all 4 of the corner grids completely blank? It is in the middle of a Samuari Sudoku Puzzle. It is the 9x9 grid that connects to the other 4 outside grids....

@@SudokuGuy I'm finding that working with the 9x9 grid in the middle of the main puzzle that has all the corner grids blank it is a little easier to try to fill those empty grids in if I get most of the middle grids figured out.
Hello, thanks for this tutorial. I've searched this question on the net but haven't yet found anything. Once you have all remaining squares with only two number (so not a BUG+1) where do you go from there?
Hello Barb Well having not seen what you have I am guessing that there are or is a matching pair there or there are no matching pairs!!! Whatever it is , maybe send me your puzzle that you have almost completed and I will have a look at it. You can send me your almost completed puzzle by going to sudokuguy.com. Scroll down to where you can send me an email and a copy of your puzzle. Robin
Question please: Thanks for all you videos Robin ... For me, it spoils a puzzle when I have to revert to a 50:50 choice and then trial and error to see if it works out or not later on the the puzzle... Is it possible to solve all Sudokos without trail and error with 50/50 cells? Or do some puzzles force the trial and error approach?
Good question My tutorial in July soon to be uploaded. I mention this. Look at my tutorial # 21 Danger Danger. I only use this when I am in a hurry and want complete. The logic is " if not this then it MUST be that" providing you have all the correct small numbers. Keeping an eye out for a danger danger is important, however when I see a potential danger danger I always try to solve it anothe way using logic.

HI AdrkSide. Same to you I hope you are having "bright " and safe time.
Your welcome
Ok, I didnt see all of the lessons. I tried x wing #1 lesson, no possibilities on the puzzle I'm working. Now I'll look at #2 lesson. I printed the puzzles I'm working on from www.memory-improvement-tips.com/printable-sudoku-puzzles.html. I chose very hard. I did the easy and hard (from another site). These are TOUGH. I'll watch your other lessons. Thanks.
hang in there cat. I have made many videos which cover many tricks and procedures. Take you time and master the easy/medium puzzles first.
Im literally sitting here crying. I thought i had it, 2nd C & 7th C top row and 8th row 2nd column and 7th. Whoa..... watching you work the puzzle mine was an x wing also I think? If not, I will be diving so deep in x wings as i feel like i am drowning anyway. Autism brain stinks. 😭😣😓😩
HI Kandi sometimes it takes watching a video more than once. There are 2 types of X wings one is using rows and the other is using columns Maybe you have watched tutorial # 63 already. Hang in there ....once you understand the steps you will succeed. it takes practice spotting X wings.
@@SudokuGuy Yes Thank you so much. I did watch 63 also. I do rewind and rewatch the parts my brain won't compute and it does help. I keep a small file box near me and one folder is puzzles to come back to, IE: called "stepped away" and after several months of watching your videos I was able to pull them all out and solved them all except one like it was my job. 😊 so i am definitely learning, just not as fast as I would like. You get what you get and don't throw a fit is my personal motto. 😁
Thanks Kandi for sharing.

I found 2 x wings but not the same design
Yes an Xwing can be found using columns or using rows. That is why I have shown 2 ways to spot Xwings. Hang in there. Robin
x=IF(A2>0,"",IF(IFERROR(FIND(1,A2&B2&C2&D2&E2&F2&G2&H2&I2&A2&A3&A4&A5&A6&A7&A8&A9&A10&A2&B2&C2&A3&B3&C3&A4&B4&C4&K2),"x")="x",1,""))
This formula determines if “1” is a candidate in column 1 row 1.
Candidate is defined as a number that does not already exist in the Column, Row or Box.
There are 729 formulas like this naming different parameters.
The formula considers the influencing cells.
The “&’s” concatenate the influencing cell values.
The FIND searches the concatenated string for a number, in this case “1”.
If “1” is not found then it is a candidate.
Writing the formula is tedious.
There is a pattern which makes it possible to automate the formula writing…more fun.
Brilliant sail.

Give a man a fish and he will eat for a day.
Teach a man to fish and he will eat for a lifetime.
Teach a computer to fish and everyone eats a lifetime, even the ones who cannot learn how to fish.
You enjoy teaching.
Use that skill to teach kids how to teach a computer to solve sudoku faster than the world champion.
Previously I described a formula that calculates candidates for one cell.
Anyone who understands that formula will have an easy time with the formulas that follow.

man .. oh ... man ... youre over complicating......
I understand what you mean, however i am a teacher and want to help the beginners learning. My self i just look for numbers in a rectangle that fit.
why do you find it necessary to alert people you are going to solve a puzzle at some future date? Why not solve the puzzle and post it….skip what appears to be nonsense.
