Sudoku. Lesson 22. Review scenarios and the skyscraper pattern.

#sudokuguy #sudoku #learnsudoku

The skyscraper pattern (Trapezium) or Sashimi X wing are difficult to spot. You will have to put in all the possible numbers for each cell before you look for it. This is for advanced players. The skyscraper can be vertical, upside down or sideways. Have fun.

NOTE A better and more thorough explanation and demonstration of the Skyscraper pattern can be watched on Tutorial # 75

You are soooo awesome!!! I love your teaching style! You an absolute pleasure to watch teach. I’ve been a teacher for 32 years, and teachers like you are a rare find! Your enthusiasm is absolutely infectious.

Thank you so much! I have been trying to understand the dang "Y-Wing" forever. I have no problem solving puzzles until I get to this point. I could never quite figure out which blocks were eligible for elimination. The "roof" concept of the trapezius cleared it up beautifully. This is singularly the best and simplest explanation I've gotten. Thank you so much for your videos!

Before I viewed Sudoku Guy, I never tried doing the daily puzzles in my newspaper. Now, I watch for them, clip them and print 4 to a page so that the answers follow the previous puzzle. I am sure to date them to keep them in order. This way, I can work the puzzles as I find time, and I have the answers if I am not sure. Sudoku Guy got me started doing the puzzles. I never thought I could do them, and I am getting better and better, trying more advanced lessons, and frequently repeating them. Sudoku Guy, you proved that a person can do Sudoku, even if
challenged, like me.

I wish to thank Sheuy 187 as he explains the skyscraper very well.  He points out what is not a skyscraper as well as shows that a skyscraper will have 4 cells, each in a different block.

Wow, I just did my first Hard puzzle and Never Guessed! The 3 numbers in rows or columns helped me find the others as you said. I was really lost until I watched this lesson 22. I also like your encouragement and feel more confident.

We've sat for two days stuck on a puzzle till I found you and your AWESOME videos.  You explain it so clearly compared to many others that you are going on my subscribe list and I'll be studying your videos to death!!  

Very happy Sudoku couple living in Chattanooga, Tennessee here!!! :D

I've tried learning this technique from other videos and ended up frustrated
then I watched your video for 2 times and I understood completely then I watched sheun videos and practised finding skyscraper now I'm perfect in this

thank you so much you're a rockstar

[anonamatron]

I've come back go this video so many times now. I can spot skyscrapers but always screw up their usage. Not sure why it's taking this one so long to sink in for me. You explain it quite clearly.

Oh my god. The X Wing, Skyscraper lessons are the advanced techniques I’m looking for. I’m very familiar with the TMB LCR techniques. However, I always struggle when I do the difficult puzzles simply because I’m not aware of these advanced techniques.

Thanks for explaining. I’ll keep watching other lessons/tutorials and look for advanced techniques like these. Thank you 😊

Very nice way of explaining a difficult task to a simple solution. Thanks

Was stuck on a puzzle for a whole hour and solved it right after learning the skyscraper, MINDBLOWN

[juliabooth]

Thank you! I actually understand the skyscraper technique through your explanation and I was able to solve a puzzle I had left unsolved.

I took that challenge and decided to see if I could find the alternative solution. One thing that I noticed is that the second row from the bottom has only one spot where you can fit a 1.
I'm not sure if that solves the entire puzzle, but it looks like it helps quite a bit.

[samwithoutlimits]

This is very helpful! I don't understand the cleaver much but the rest I can use.

[miaash]

You look terrific!
Thank you for an excellent channel.

Hi Sudoku Guy & thank you for helpful videos. I was wondering *why* this 'Skyscraper' pattern works though - what's the numerical / mathematical basis behind it? I think this would help me use it in practice. Thanks

[MaTuLa]

Thanks for the explanation! Also found this to be called a Sashimi X-Wing.
