Completed, excellent puzzle , keep it going. Ron

[@SudokuGuy]

Thanks, will do!

[@bttceb2004]

Hi Robin, great puzzle, I enjoyed a lot. I spotted a X-Y Wing that leaved a single in a column. The rest was much easier. Thank you for your lessons!

[@SudokuGuy]

Nice work! there are several ways to solve this puzzle. congratulations for finding the XY wing.

[@SoRTs6233]

That's more like it! Something to get your teeth into! Found a skyscraper, rest was easy. Looking forward to seeing your solution! Take care

[@SudokuGuy]

That's the plan! There are several ways to solve this puzzle. Congratulations for solving. Did you use a computer or was it on paper?

[@SoRTs6233]

@@SudokuGuy I always use paper, in fact, I bought a supply of squared A4 jotters specifically for Sudoku! Cheers, catch you later.

[@jamesgoacher1606]

Yup that was better. I needd to use a couple of 'Chains' in two colours first then came a 'Swordfish' which just about did it with one more double colour 'Chain'. Thanks, needed a little thought. Looking forward to your analysis.

[@SudokuGuy]

Yes there are several ways to cook and egg! Well done.

[@dsremingto]

Xwing advice did the trick. Had to go back to early lesson to learn technique . Fun!

[@SudokuGuy]

Rock on! Bernadine. You can do it!

[@jimchalkley7961]

Thanks to your teaching skills I had no problem with this puzzle.

[@SudokuGuy]

Well done Jim.

[@HITARIX]

I will try to solve it myself and is excited for your try!

[@SudokuGuy]

Go for it! Robin

[@robertbrodine9841]

Thanks Robin! When I put it into my computer to see all the little numbers, it said that it was asymmetrical. I don't exactly know what that means, but I solved it anyway with no problems. Some nice X Wings and a Sky Scraper.

[@SudokuGuy]

Wonderful! Well done Robert. See my solving check my try on June 27th my time.

[@h0016911]

I used x wing and skyscraper to crack it. I look forward to seeing the methods you use !

[@SudokuGuy]

Well done sammy. There are several techniques you can use.

[@dsremingto]

Well you certainly took us from easy to hard. All those original digits made me think it was a breeze. I'm still struggling looking forward to your help!

[@SudokuGuy]

You can do it! Bernadine. I hope you learnt something from this. Make sure you watch my solving. There are several ways to solve this puzzle.

[@mariawiderstand9390]

This puzzle was very hard for me. It took me three times to beginn and the last time i solved it very easily. I did not see the obvious in the first time. Thank you so much, i learned a lot by doing this puzzle.

[@SudokuGuy]

That's great maria. Have a look at my solving when it is uploaded around March 27th. there are several paths you can take to solve.

@@SudokuGuy Thanks you sir

[@petrahobby1518]

I solved it 😀

[@SudokuGuy]

Congratulations. Did you use a computer?

[@petrahobby1518]

@@SudokuGuy no 😀 i searched for single numbers, and then, wuupp , done 🍀

[@SudokuGuy]

@@petrahobby1518 Well done Petra.

[@AnonimityAssured]

The key cells are... R5C7 and R4C7. The rest is straightforward.

[@xskyzel]

Those were the two first digits that I solved too!

[@SudokuGuy]

Please tell me how you used these 2 cells to solve.

[@AnonimityAssured]

@@SudokuGuy Colours on 6s for both cells. I noticed that 6s looked most promising as a way in, as they were greatly channelled by filled cells, especially in box 5. By 'colours on 6s', I just mean following 6s. From each of the two mentioned cells, they very quickly lead to a conflict - one directly and the other by excessive constriction. Technically, it could be considered a form of bifurcation, but I think it's contained enough to be a legitimate logical technique.

[@xskyzel]

@@SudokuGuy yeah, I'm not quite sure of the solution right now cause I did it last night before I sleep, but by isolating all numbers, I remember that those 3 and 9 were the first two numbers I put! 😅

[@tenbears845]

Yep it is a dandy, took a good hour.

[@SudokuGuy]

Congratulations if you solved it without a computer.

[@tenbears845]

No just printed the screen shot and solved with your standard approach. With that there were several choices which I followed and on the third attempt I broke through. Excellent puzzle. I still can't see things like swordfish and skyscraper and am slowly getting better at finding the hidden numbers in groups

[@leejohn4597]

Who invented sudoku??

[@SudokuGuy]

Howard Garns a 74 yr old retired architect. The name was registered in Japan in 1986

[@oootkarsh]

This is too hard for me. It's almost like a trap. Your mind immediately jumps to the conclusion that it must be easy because there are lots of numbers. I AM AT MY WITS' END.

[@SudokuGuy]

Hello DJ Please do not be frustrated. Many players asked me to do a harder puzzle. Look at my solving of it when it is uploaded around May 27.

[@venkataraghotham7586]

I have sent the solution to your Instagram account.
