One tip that I've picked up from watching these is to train yourself to occasionally scan the numbers in the rows and columns, looking for places where lots of different numbers overlap. Those are often places worth looking at more carefully. R8C7 is a perfect example. If you scan the board you can see quickly that C7 has 2347, R8 has 3689, and 1 is in the box. So bam, you've just found a naked single 5. Also look carefully at houses that have only a few empty cells, and make a note of what's missing from them. e.g. C5, which starts out with 5 digits given, leaving just 1238 to go. After checking the overlapping houses, while there are no singles out of the gate, you have already found two bi-value cells.
@YourCritic2 жыл бұрын
When Mark said pause, I spotted a naked 5 without even having to pencil anything in. Similar strategy to Mark's - I looked at cells with longest lines of intersecting digits and found that in box 9 the cell to the left of the 9 can only be a 5. Admittedly, that 5 placement doesn't seem to open up the puzzle much so eventually, the 2 on the third box would have been required.

In my month or so of following this channel and playing some of the games, I've realized that Snyder notation is very good for most traditional sudoku games, but it also tends to make some of the more complex puzzles and techniques harder. The main problem with it is that logic techniques that rely on elimination and spotting broader patterns don't stand out as much. In particular, patterns like x-wings/fish are hard to locate, as they rely on noticing exactly which, where, and how many candidates exist in certain columns and rows. I guess in the end you need to learn how to balance the use of Snyder and traditional cell-based notation, and when to switch between them.

@grahamfisher3078 ай бұрын
I don't have link to play it, so would have to use a hand drawn grid. My start point would be a single 5 in C7 - that with3 & 7 as well as the 3, 5 & 7 in R2 gives those numbers as a triple in block 3. That means that 2 has be be in R2 of block 3, and places itself in R1C3. R2 becomes a single 8, the 7 goes in R3C1, and that gives 2 more 7s around the grid, and at least one 2 follows also. Now I'll watch, and my next number when the question came u is R8C7 = 5, and that wasn't the answer which was 2, a number I would have found a couple of moves later.

@rabidsamfan5 жыл бұрын
On paper, after I've found the pairs in squares (snyder notation marks) I "think outside the box", i.e., I make a note of which digits are left to go into the most crowded sets. So on row 2 my note was "12689" for example. Then it's fairly quick to check each of the cells in that row. (I also note cells which only can have two digits, so r2c3 got a "2/8" note which was very quickly resolved when I found the 2 farther over.) I'm not super fast, but I get there.
@dancollison15 жыл бұрын
I also have trouble seeing them, but, for now, the best I can come up with is to scan for the most restricted rows or columns, then see if they intersect in a 3x3 box. Or, find the most restricted 3x3 box, then look for the most restricted rows or columns feeding into that box, scanning to find the rows/columns/3x3 boxes with the least numerical overlap. Or, if I have thoroughly notated using Snyder notation, I look for cells with either no or a single Snyder little number, and test them for naked singles. If using a pencil, I mark unused numbers "outside the puzzle" adjacent to the candidate rows / columns / 3x3 boxes (demarking the 3x3 candidates with a squiggle line next to it, using a double squiggle to demark the numbers for the central 3x3 box (Box 5). Hope this wasn't too simple minded an answer.

The hell of a long time? Eight minutes?? Man, you've no idea what a long time is! I normally solve difficult puzzles in - oh I don't know - five to ten minutes, maybe - occasionally much faster, though. But I have one that I've spent years on NOT solving! I had a Nokia telephone once (who didn't?) with 100 puzzles on it. The first 90 were ridiculously easy, but the last 10 were hard, and one of them is just about impossible. On the phone you can cheat, and I did that once very quickly just to check that there was a solution, and there was. I often keep a print of this puzzle in my bag to show to people who think they're good at solving sudokus. You can very quickly write the first number, a 5. But I've never met anyone, myself included, who could get any further.

The traditional full notation system is inefficient for speed solvers. The numbers clutter up the board, often hiding as much as they reveal, and valuable time is wasted unnecessarily filling in and removing marks. They prefer to use a more streamlined method called Snyder notation, that (for the most part) only adds candidates when there are exactly two possibilities left in a box. They have designed their platform to work the way they do. There are plenty of other programs out there that will automate that kind of thing if you want to go the regular route.

Too bad, I only play easy difficulty puzzles And there is always an empty house (9*9 box)

9*9 box is never empty unless you're the one creating that sudoku.

I still don't know how you found that 2. In the same row, why couldn't it go above the 8? or next to the 7 or above the 9?

It could go in those places, but as he mentions when looking at the middle square then: 1. from the row 5, 7, 3, and 4 are present and ruled out, leaving 1, 2, 6, 8, and 9; 2. from the column, 6 and 9 are present and ruled out, leaving 1, 2, and 8; 3. from the 3x3, 8 is present and ruled out, leaving 1 and 2; 4. from placing the 1 in the only places it can go rule that out, leaving just the 2. Therefore, as there is only a 2 possible that can go in that square, it is what's called a "Naked Single" and so that square must be the 2. If the 2 was placed above the 8, it could not go in the middle square, but neither could any other number.

@@msclrhd Okay I see it now. I started to do that in my sudoku games. Eliminating possibilities from a certain square because of the row columns and the box.
