I really appreciate the effort it took to edit this video using a puzzle that you have already solved and then doing the voice over for it. Great job of explaining the Snyder Technique!!
Thank you so much. This was a terrific video. Your explanations are so clear. I had been marking in every candidate (NY Times on my phone, so not too messy) and it would take me over an hour to solve a medium or hard level Sudoku. Sometimes out of sheer frustration, I used the auto-candidate mode, but as you point out, that's not really "solving" the puzzle - I was just rotely entering numbers in cells where I spotted only one candidate. Sometimes I would randomly guess at a number in a matching pair just to jumpstart the process, and if it were wrong, I'd use the other one. Not very elegant. I can't wait to try this new strategy using Snyder notation. I just wish the NY Times had a tool for drawing in temporary intersecting lines - sometimes I miss things trying to visualize the lines. Thank you for doing this.
Thanks Andrea, I appreciate the feedback! Everyone has different strategies that work for them, so as you progress you will find your own method. But Snyder notation is a pretty standard way of beginning to solve a puzzle, but you will see later in harder level puzzles you may have to put in more candidates to see the pattern, so stick with it, we will get there! Most of all, enjoy your Sudoku journey!
The key is using Snyder not only for doubles, but also for triples. The same 3 numbers in 3 cells would eliminate them from the rest of the raw, column or a box.
@@Globeisahoax I agree that identifying triples has been very helpful to me, but I think technically the term Snyder notation refers strictly to finding two and only two possible locations within a row, column or block, creating a true or false situation. So pencil marking triplets would not be a use of Snyder notation.
In the Sudoku app that I use, you are able to replay puzzles multiple times. I like to do each puzzle by placing the pencil marks myself, as suggested at the beginning of the video, then I replay the puzzle using the auto placing of pencil marks so that I can get the completed time as low as possible for myself. Both ways of playing the puzzles are enjoyable for me, but or different reasons, which is why I do each puzzle two times.
I am working on today's (6.30.21) New York Times Sudoku puzzle at the "hard" level. I used the scanning technique, then I went block by block applying intersecting lines to enter as many numbers as I could using Snyder notation. Now I am stuck. Is it just that I have not yet learned enough strategies to proceed, or am I missing something? I have completed "hard" level puzzles before, but usually I get a jumpstart at this point more from incorrectly entering a number in a cell or guessing, which allows me to then deduce the proper cell. So I am essentially blundering into it more than using logic at that point. I am resisting enabling the auto- candidate feature. Just wondering how to proceed or if I don't yet have the tools to tackle this level? I have a screenshot of my puzzle at this point. Thank you.
Once you are stuck, then you need more than Snyder notation, start looking for cells that can only have one candidate, or logically eliminate all others....its a hunt, sometimes cell by cell. And once you break one, the rest follow. You might want to use "hint" on the NYT site to see if that helps. I will keep providing more strategies in upcoming videos. Snyder notation is very helpful at the easy and medium levels, and at the beginning of the hard level, but at some point you may need to look at all the candidates in a cell for a row, column, or block, to then see something otherwise hidden.
@@LearnSomethingNewEveryDay @Learn Something Thank you. That lifts my spirits and gives me hope - I didn't want to be expelled from Sudoku U. 😉. I actually enabled auto-candidate for a few minutes this afternoon hoping to spot one cell with a single candidate, but to no avail. I don't know if the Times gives me increasingly more difficult puzzles, as I have been plodding through all three levels for several weeks. I will look at "hint" next, as you suggest. I have definitely observed that once I figure out one cell after being stuck, many others fall into place very rapidly. I will keep going and, as always, look forward to your next lesson. Thank you.
Too bad the soft dont offer center and corner marking for candidates. Corner indicates numbers in the box and center indicates numbers in the cell. Center marking helps in getting doubles and triples, that lead to a fast solve
Exactly!!😊Thanks for pointing out the obvious;)...I was actually looking for a comment acknowledging that!😅 So that matching pair could have been unmatched and entered accordingly in lieu of her explanation at 10:10... cheers!😸
The question is, do you even need these notation method on such an easy puzzle? It makes it difficult to figure out how to use it on more difficult puzzles…..

Excellent and really clear! Thank you!
I find your lessons to be very thorough and easy to understand. Thanks!
Thank you Hi Hi, I appreciate it!
This is an excellent presentation . Your highlights and arrows together with your explanation are really helpful .

@@Tee-Catin So we can call it Snyder Plus notation
@@Tee-Catin or using Snyder technique to find not only doubles, but also triples. Whatever works to help solving faster and easier
Your videos are easy and practical, they are amazing! Thanks for all the tutorials.
Glad you like them, and thanks for the comment!
All of your beginner videos are awesome!
Thx . Very lucid explanations...
I learned something for sure!!!
Excellent presentation ... thank you so much!
Excellent lesson. Learned so much. Now if m can only remember it all!
Thanks a lot. It's very helpful to me to solving sudoku.
Great we’ll done. I did learn something
Thank you, great video!
Glad you liked it, thanks for the comment!
See 10:10, the "matching pair" were due for a separation by noting the 3 sitting in the block below.. 😊
Thanks a lot for the videos. They are very useful.
Glad you like them, and thanks for the comment!
Great videos. Helping me realise how untidy my logic is. :)
Thank you so much..

Yes, I learned something
Thanks sir.
Why did this puzzle change after the first few minutes. A whole different puzzle was presented for solving.
Too bad the soft dont offer center and corner marking for candidates. Corner indicates numbers in the box and center indicates numbers in the cell. Center marking helps in getting doubles and triples, that lead to a fast solve

The question is, do you even need these notation method on such an easy puzzle?
It makes it difficult to figure out how to use it on more difficult puzzles…..

I M sorry but i find you going to fast. But i solve the problem I watch the video again and
Hope to understand but if not watch it again. L o l
