Your channel is the only one that explains everything sufficiently enough to make the information useful. It seems like some others just try to show off under the guise of giving a tutorial. Yours actually instructs and teaches. Thank you

@deirdrejs6593 Год назад

That is the first tutorial of yours that I have done. It is by far the best explanation of the many many vids I have watched regarding triplets. Thanks so much. I'm looking forward to watching more of your tutorials.

@LearnSomethingNewEveryDay Год назад

I'm so glad it was helpful! I'll be putting out more videos soon, hopefully during my winter break. Thanks for the comment!

@davidfusani Год назад

These videos the best Sudoku tutorials by far. You eliminate any extraneous comments and spare us the cute asides, thereby making it possible to focus on the techniques you present. Thanks!

@georgefulton8152 6 месяцев назад

You are an exceptional teacher. Your videos are so concise, no extraneous dialogue to wade through, with total clarity! And your graphics are really just so perfectly clear as well. I imagine you must also be a school teacher, because you seem truly unselfish in the way you present information. You make it about clarity first and foremost, no attempts to appear clever, just thoroughly helping any viewer who loves Sudoku. This was exactly the tutorial I needed for some tricky puzzles. Thank you.

Very systematic procedure and exclamation. @5:15 you identified a triplet 6,7&9 in column 5, block 5 whereas these numbers are also present in the same block in the row. I did not understand. Could you please clarify.

@calypsopiter Год назад

Someone's passion, like yours, invigorates, helps to learn a lot and make it interesting and satisfying 👍 thank you for your passion 😊

@RWBHere 6 месяцев назад

For your last example, I was almost shouting the open 1,5,7 triplet in block 2. Thanks for the video. 4 x 4 Sudoku puzzles are even more fun, especially if you don't mark possible numbers into the 16 x 16 rows and columns. Both puzzle types are great for memory training if you tackle them in that way.

Ive watched a few of these and they are really great. I understood naked triples fine but, when we start talking about triples that are hidden and split amongst several different cells, it feels like it could just be any combination of numbers. What cant it be? What are the parameters 7:07

I've loved your sudoku tutorials. I wish you would do some tutorials on suguru/tectonic puzzles. I know some of these methods can be used for suguru but it's a bit more complicated 😅

One of the better explanation. Still went over my head but a little less confusing

@eugenetswong 3 месяца назад

A good way yo understand this is to create a row of triplets, and then hide them, and then try to imagine how you would discover them.

@user..Aa..Bb.. 3 месяца назад

@divermike8943 3 месяца назад

I've watched this video multiple times and its great, It gets my thumbs up. BUT, there is not really an explaination as to why a triple allows you to eliminate the the three numbes outside of the triples cells if they are in the same "house"=row, column or block. The reason you can eliminate the numbers that make up the triple everywhere else in the same "house" is not shown. I think it would be best if that logic was shown. I think I get it. Here is my explaination. Regarding the triples in block 7. The Cells, G1, H1, & J1 contain only three numbers (1,7 or 9). If say H2 was a 9, then G1, H1, & J1 could not contain a 9. But if that is true G1, H1, & J1 could each only contain a 1 or a 7, and that can't be. You have only two numbers to use across three cells. Two of those cells would have to contain the same number twice and that breaks the suduko rule for Column 1, and Block 7. You can't have duplicates.

@andreas-hf6ec 11 месяцев назад

Great tutorial! I have no trouble using the techniques described in the video but I wonder about the logic behind it and why it works? Maybe im to stupid to understand it

@brucewernick6542 2 года назад

Triples are amazing. The naked triples are easy to see. I need practice to spot the hidden ones. Does anyone know of a website that has triple practice examples?🏋

@gaynorwilliams4033 2 года назад

Why couldn't the 769 triple be the three going across the same box - row 5, columns 4, 5 and 6? I don't understand?

@dianewendorf2242 Год назад

My question too!!!!!!!! Wish she would answer. There is no explanation of why not.

@MacXpert74 Год назад

Because in column 5 the only three numbers missing were the 769, so they HAVE to be in the middle top to bottom three squares of block 5. Another reason why the left and right squares in that block can’t contain a 769 is because there’s also a hidden 23 pair in those same boxes. So you can erase the 769 from them for that reason as well, just as the other 3s in that row in block 4 and 6.

@redcreeper2521 Год назад

Great video, but I don't understand what happened to Snyder Notation?

@lostwanderingprince Год назад

Can a matching pair or triples be said as pairs or triples even when they are in a diagonal arrangement in the same block and they aren't a parallel straight line (horizontal and vertical)? Could this even exist? Are pairs or triples must always be besides each other? I'm confuse about this thought. Thank you.

@philbaum449 Год назад

Why cant you use the 679 in row e as the triple?

@lukejuras8024 11 месяцев назад

Because there are other places in that row (in box 4 and box 6) where the numbers 6, 7, and 9 can go. It is only a triple if there are only three cells in a unit (which can be either a box, a row, or a column) left for those three numbers to go.

@didi7680 2 года назад

I am so freaking confused still. Is there a sudoku for dummies? One thing I need to know for sure is, do I have to fill in every single space before eliminating ANYTHING, or can I do random blocks, rows and columns? Sometimes if i go to another section randomly i have to put back in a digit to make THAT section have legitimate possibilities or eliminations. Do I make sense? haha. I don't even know how to state a question due to being so confused

@LearnSomethingNewEveryDay 2 года назад

Maybe watch one of my "solve with me" episodes, start with Episode 1 for beginners and work your way up, and think with me as we solve together. Hope that helps you! If you go to my channel page you'll see the list of solve with me videos. Have fun!

@TrungHieuNguyen-sz2tu Год назад

@jimdouglas1425 Год назад

Am I to assume that the 2-3-8 and 3-8 in columns 4 and 6 are not part of the triplets action because the other 3 in columns 1,7, and 9 are naked? Otherwise those in columns 4 and 6 could be hidden...making the row have quintuplets!

@lukejuras8024 11 месяцев назад

They are not part of the triplet because they contain other numbers, 1 and 7. In order for it to be a hidden triple, imagine that there were no 2s, 3s, or 8s in columns 1 and 9. Now you could eliminate candidates 1 and 7 from rows 4 and 6 because there are only three spaces where the three numbers, 2 3 and 8, could go - 1 and 7 cannot possibly go in those squares.

@mendy3115 Год назад

What is the logic behind a triple when one of the cells has only 2 digits?

@lukejuras8024 11 месяцев назад

Watch at 6:02 again. It's a triple if there are three cells for three numbers, and those numbers can't go anywhere else in that unit.

@andreagrazianodibenedetto1464 11 месяцев назад

You lost me at the hidden single at 4:31 and at the hidden triplet at 7:57 respectively.

@Bodkin_Ye_Pointy 10 месяцев назад

Sorry, I could not finish the presentation. I would have solved those puzzles without complicating it with "Triplets". For instance, the top row solved itself based on the information at hand. It was clear where the 6 should go. It was clear where the 9 could not go and that left a default position for the 1. Job done, no Richarding about with "Triples".

@Philomate 2 года назад

At the end, why can’t the hidden triplet be 138 instead of 238?

@Mrbiggestbawss 2 года назад

It's because 1 is in other cells as well. Can't be part of the triple because it's not contained in those 3 cells

@Harker777 5 месяцев назад

This is somewhat a ridiculous path to go by. 1:44 - It's obvious that the two goes in column 1. Why waste time notating every possible number per cell?

@Tee-Catin 2 года назад

I understand in the example at 7:04, you are discussing naked triplets rather than hidden triplets, but if we did not know know that, couldn't either cell A4 or A6 also be possibilities for the 2,3,8 triplet - hiding behind the 1 in A4 or the 7 in A6? My other question is, we would have to have all candidates for the entire row filled in to see these possibilities, is that correct? In the last two lessons, some of the examples have started from that premise, if I'm understanding correctly. One of the challenges I'm having is that when I get past the early steps (scanning, intersecting lines and completed segments), I start to fill in all possibilities for rows and columns with only three or four empty cells, and I lose sight of cells that only had candidates noted with Snyder notation. It seems like instead of eliminating candidates, I am sometimes headed in the opposite direction. I hope this question makes sense.

@LearnSomethingNewEveryDay 2 года назад

Hello Andrea, thanks for your question! Snyder notation is very useful in the beginning stages of solving a puzzle. If you are working with a more difficult puzzle then eventually you will have to fill in all the candidates to see patterns emerging. If you are working with pencil and paper you can write the Snyder notation one way, say in a corner of the cell, and the cell notation in the center so you know which is which. As for you first question, A1 can only be a 3,8, A7 can only be a 2,8 and A9 can only be a 2,3 and nothing else, so those cells MUST have those 3 numbers and nothing else, therefore any other cell in the same row can't have those 3 numbers. Once we see that triplet, then we can eliminate all the other 2,3,8's in the row. I hope that helps!

@Tee-Catin 2 года назад

@@LearnSomethingNewEveryDay Thank you! I will study this triplet example more carefully. I work from the NY Times Sudoku puzzles on my phone, usually the medium and hard levels, so it's not possible to customize the location of the Snyder notation within the cells. Lately I believe I'm making better use of those cells with Snyder notation candidates - by that I mean I have been able to find more numbers before I need to switch to filling in all possibilities. Thank you for helping me LEARN SOMETHING! 🌝
