Nice to see the rule spelled out, I've seen you guys use it for ages but it didn't "click" that it's normally used when there are only two possibilities in the box. I just tried the puzzle with this in mind and it helped a lot to know that once you remove or overwrite one mark, the other automatically becomes true, without scanning the context.

I think Simon has said that for him he uses it for digits restricted to 2 positions in more classic Sudokus to avoid cluttering the grid, and 3 positions for Sudokus that have other strong restrictions (like anti-Knight or something) where knowing it's down to 3 might be more relevant.

Using Snyder notation, you could have placed that 1 without looking at 2s. In Box 2, Snyder notation places a 1 in column 5, which limits the 1 in Box 5.

Thank you, Simon (and whoever convinced you and/or Mark that these would be a good idea). I knew about Snyder notation from your comments in earlier videos, but it's nice to see it laid out like that. I've used Snyder notation on occasion when solving Sudoku (I'm advanced beginner-ish), but I was inconsistent and haphazard at best. I was delighted to see how far I could get into the example puzzle with this notation. I'm still not quick, but eh... I'm here to enjoy sudoku, and speed is only one small part of that for me.

After penciling 1s into two positions in box 6, you can also pencil 7s into exactly the same two cells. You can now switch from corner pencil marks to central pencil marks in those cells to indicate a 1/7 pair. Central pencil marks indicate which candidates a specific cell in the grid is limited to. You know that one of these cells has to be the 1, and the other has to be the 7. No other candidates can go in either of these cells. If you tried to place any other number into one of these cells, the remaining cell now has to be both a 1 and 7, which doesn't work for obvious reasons. See if you can use Snyder notation to find another pair in box 4.

The problem I have with Snyder notation is that for an inexperienced Sudoku player, it's very difficult to spot something as simple as naked singles using it because if you would have pencil marked every possible position for every number, a naked single becomes immediately apparent - not so if you are only marking numbers that can only go in 2 positions.
@PedroContipelli2

I find that marking every possible position should only be used as a last resort as it actually obscures more than it helps. There is such an overload of information that simple pointed pairs are harder to spot and use.

@@PedroContipelli2 I actually switched back to marking every possible position and have found it immensely more helpful, so to each his own. I find that the more advanced techniques typically don’t come into play in most puzzles until AFTER you eliminate all the other more obvious ones (like nakeds, hiddens, etc.) and by then the pencil marks dwindle to a much more manageable amount so it makes it not very difficult to apply advanced techniques. It would just irritate me to no end to get stuck on a puzzle using Snyder notation because I missed a naked single somewhere

Weird, my previous comment almost immediately got deleted (was it because I mentioned a sudoku app that I dislike?), so I’ll just post my timing on this one: 1 minute 55 seconds. 😊 I admit I was helped a bit by pencil mark auto-eraser (the one that, if you put a digit in solid, erases all pencil marks of that digit in the same box, row, and column), but other than that, I was all by myself. Been solving classic sudokus on my phone since around 2012, with a couple 1-2-year breaks, but I still have a lot to learn about the harder puzzles, so I’m subscribed to this channel. :)

Sorry, I'm not at all convinced yet. That's a specific scenario and most of the time a digit can be in three or more cells which means I could never mark them and thus lose track? Also let' say I mark three cells e.g. in a L-shape, with the next known number, I can either still delete two and end with one or delete one and end with two which is at least as good as this. I feel like if I don't mark numbers that can only go in 3 or 4 positions, I will oversee a lot of restrictions and more often than not lose time instead of saving it. I'm not an expert though so if all experts can juggle all the restrictions in their heads with ease then (and imo only then) this tip might be helpful - but not for normal level solvers. Please let me know if I'm wrong! Edit: Usually you'll also use center and color marks so I feel you won't come far using ONLY this "trick".
@bjorn9875
2 жыл бұрын
This is meant as a compliment to other stuff, such as center marks. As you say, with only this "trick" you will still not get very far, but by using it, it helps make a lot of other techniques more easily found. (X-wings, for example). It's also very useful when a digit is limited to a row or column, but the cells themselves might have very little limitation. As for why it's suggested to not mark when it applies to more then 2 cells is not critical, but in a classic sudoku when your forced to mark 3 cells, it can sometimes cause more confusion then it helps. The less markings you have, the more easily you can find "weak" cells, or combinations that matter. If you get to a point where you have marked everything that feels important, then you can start marking >2 possibilities/region, but until then, it's generally easier to see what is going on with fewer markings. (The same reason we generally don't fill in all options in the center of all squares, but only those that have a few options.) Edit: Also in non-classic sudoku I very often use this notation for >2 cells, although often limited to max 3 cells, but that's a different issue :) Edit2: I'd go so far as to say that this technique is meant to avoid having to juggle restrictions in your head, by writing out "likely relevant" restrictions, and only such. The idea is that you don't need to solve it in one pass, but by finding more and more restrictions, you can look at previous stuff and find new restrictions thanks to you easily being able to see markings.

Snyder notation is specific for when a digit can _only_ be placed in exactly 2 positions. This is why there's a different notation for Snyder notation up in the corner, so that you can distinguish it from other types of pencil marking and coloration. The reason it's such an important tip is that the _binary positioning_ is specifically important to getting you placable digits, while other types of pencil marking or coloration fill other purposes. While 3 or 4 _MIGHT_ be helpful in an L shape, it's not until you get good at using it for this purpose that you'll know when that might be useful or when that's giving you too much to look at. You get a really good sense of the differences in how those multiple types of notation are used in how Simon differentiates them in the videos, and you can even see how he & Mark use standard pencil marking very differently from one another.

This is not the only trick. You have to remember they only have a minute to show you something. This is an example and it will not show you all different scenarios. This is a method you just start with when you are searching for naked singles. By using this method you might also find pairs. These pairs can then be used to possibly find even more cells to notate. This is definitely a very powerful tool to help you solve and keep track of what's going on. There is nothing wrong with notating three different cells. Usually you start with looking for those that only have two possibilities to keep it simple. Sometimes it's not good to clutter up the grid with pencil marks. When you go down the list of numbers you hope you will get many of them. This technique is only one example of different ways to notate cells. There are also center mark and coloring which have become huge in solving. It's not going to solve the puzzle for you but it will help you keep things straight and give you important information. Again, please remember they only get one minute and it's impossible to give you all the techniques in one sitting. It's very possible you will be given other techniques in future shorts or if you go and watch the channel you will see these techniques in action. The channel shows live solves with a lot of variances in the rulesets. They also do the classics Sudoku which you will see a lot of different ways they notate cells.
