Sudoku is now finally comprehensible for me. Thanks for the informative (and calming) tutorial.

This seems really hard !! Am i wrong??

Repeats too much video could be much shorter

I have been following your Sudoku tutorials and my solving capabilities have been improving. Thank you, Madam for your articulate explanations and explaining each step repeatedly. A request - what software do you use for colour marking the lines & colouring the squares & candidates. Thank you in anticipation 🙏

This game was very good , I enjoy the games with out the red lines circles better, thank you for your help !!!

Ok but how do I figure out which number goes in which block

This is my first time trying the sudoku puzzle. Thank you for your step-by-step instructions video. Now I understand the puzzle better. Now I will try on my own.

burp?

Thank you for explainng how the game is played. Very helpful.

3:43 tells all

I like to know which blank Sudoku software are you using for this demonstration ?

HOW IS THIS A LESSON FOR BEGINNERS, WHEN YOU USE SOME MAGIC ASSISTANT TO FILL ALL THE CANDIDATES @3:22 ? HOW IS THE BEGINNER SUPPOSED TO DO THAT?

Off topic. You showed us an online template we could use. Can you provide the link as I am unable to find it. Thank you.

Eliminate 1 on cell 3

This was not a hard puzzle, but with only 23 givens it was rated hard...not because it would require advanced techniques or strategies. I think NYT just took the easy way of categorizing the puzzles. It seems to be the lazy way a lot of people rate puzzles. Of course they won't say "lazy"...they will say "efficient". Reminds me of my son! LOL 😍😍

This particular tutorial is just what I needed to help me when I write in all the candidates. It is pretty daunting at the beginning to try and find the triples with all those little numbers scattered everywhere. But, when you highlighted a single column and dulled down all the other columns, it was so much easier to see the triples. Now I am able to complete intermediate puzzles at last and I want to thank you for helping me out. You are an excellent teacher.

Excellent tutorial!

Just started solving sudoku and your tutorials have helped me get my very basics done pretty well.

I’m stuck in a sudoku puzzle 😢 How can I share it with you?

In row 8 column 2 why didn't u eliminate 5 from there since u said all 2,3,5,7 to be eliminated in block 7 as there are triples

In minute 5.51 you are too fast, you missed the position of the 9s in the central block (a very helpful construction, because the nine from below blocks the only free cell in the upper line of central block!) and so also the position of the nine in the right central block

Excellent 👌 teacher

Thanks a lot! 😊

This doesn't feel like a beginners lesson as it is so hard to spot those triples when all the candidates are placed. You are explaining it very well but I guess it's just practise, practise, Wish I had your skills.

In row 8 , column 8 , the number 2 could also be a candidate . Not only the number 4 and the number 5 right ? which means the 4 and 5 are no longer naked pairs right ? Appreciate your feedback , thanks for the videos !

Good explanation great job😊

The first example was at first very frustrating to me because I couldn’t find any use in the excluded 3. There‘s just no follow-up. But it made me look very closely until I managed to spot my very first xy wing 🎉🎉🎉 Hurray! There‘s one with the pivot in R3,C9, x in R3,C3 and y in R9,C9. It conveniently excludes the 2 in R9,C3 and the whole puzzle unravels easily, even disregarding the empty rectangle trick. So, while it was an underwhelming empty rectangle it would make an excellent example for a super helpful xy wing 😅 Thank you!

Well I definitely ‘Learned Something’! I never knew about hidden triplets. Thank you so much for your most clear and precise Sudoku instructions. In my opinion, you are the best on the Internet!!

I like your presentation very much. It's crystal clear with necessary visuals. I now stick only to your channel to learn Sudoku.

This lady is a born teacher.

Super helpful!😊

Which program do you use for sudoku??

thanks for your videos, I also know a little about sudoku strategy, but I can't speak english as well as you because I'm old and I've been in Vietnam all my life, thanks anyway.. I have solved and posted about 400 sudoku games on my youtube channels, some of them were requested by viewers to solve for them.. 😍😍😍

Very hard Thank you

Great teacher!🎉

Excellent video. Great teacher.

Thanks❤

Thank you for your hard work

Key thing to remember in finding X-wings or Skyscrapers: 2 "Sides" (2 columns or 2 rows parallel to each other) have to consist of Conjugate Pairs (only 2 Cells in Separate Blocks in a Column or Row contain the Same Number ie in video: b2,h2 and a7,h7) and that on the Third "Side" (in this case, the "Base") the Ends (h2 & h7) just be lined up in a Row or Column. And No, the Base DOESN'T have to be a Conjugate Pair or Matching Pairs. REPEAT: The Ends in the Third Side Doesn't have to be a Conjugate Pair or a Matching pair, they just have to line up. Sounds weird I know, but in a Skyscraper it's on the "Roof" (b2 & a7) where any Eliminations take place. Btw, same rules apply in an X-wing too! The Ends of the Roof (say if was b2 & b7) Doesn't need to be Conjugate Pairs or Matching Pairs (just like in the Base) they just need to Line up. Of course, the difference here is that (as opposed to a Skyscraper) you can also make eliminations in the Base too. Whew! Hope that helps guys! ✌🏼

At TS 8:25, why eliminate the 9 in G5 but not the 5? The logic for removing the 9 seems to apply equally to the 5. Did I miss something?

Do you know of a tutorial on how to use f-puzzles

I would like to see from beginning to the end

WOW I am having a brain indigestion !! I am going back to beginers ...beginers ... thank /you any way....

It helps me a lot thanks

Thank you so much🙏🏻

Very good

I was able to solve the puzzle in 30 minutes, using pencil and paper.

I don't understand the hidden signal... 6 could have always gone on the top left cell.of the top ri8 block... so why did you put in the left bottom cell of the block?
