Means it’s obvious. By the time he’s just doing ‘by sudoku’ he’s just filling in the only number available in that square by the basic rules ‘of sudoku’. For example, if there is already 2,8 penciled in a square, when you get the 2 in a different square in the same row, then the penciled square gets the 8.

They do (hence where the name came from!) and they have at least one example of a sudoku solved on paper very early on in the channel's history. They also have quite a few other examples of non-sudoku puzzles from tournaments as well, which are stunning. You might be able to sort by oldest and flip through until you find it. The sudoku I'm remembering specifically was a strange 3d sudoku variant where you can actually fold the paper into a cube, but I think they might have had at least one other as well here.

The commands to swap between corner pencil marks, center pencil marks, and final number selection are all hotkeyed, and if you watch closely, you will often see him cycle through several numbers while saying the final number he wants because he is likely not an efficient typist. So several keystrokes to change marking types, then several more as he discovers he's off on his finger position when typing digits.

I've called a couple puzzles, "poster-childs for disciplined pencil-marking". This didn't seem like one of them, at least not at first. I penciled a few digits from 1 to 9, but didn't place any digits, or even fill any cells. It would have a futile exercise returning back down to 1 and redo the penciling. So I tried a few candidate cells, hoping for two-digits. Finding one in a corner, I followed a hunch and tried all corners, getting two digits in each. It did take me a minute or two to recognize the pattern as a Y-wing or bent triple -- allowing me to place my first digit, as well as my 2nd, 3rd, and 4th. I can't say it was plain sailing afterwards, but I encountered nothing memorable other than not spotting digits seeing cells. 6:00 So far, the path followed was very familiar. "You will never see a better example than this, to teach you" what a Y-wing is. Not true. There was that teaching puzzle that featured a chain of Y-wings, and perhaps one other with half a dozen or so. 8:40 This may have been my first case in the puzzle of not noticing something. I placed the 9 in box 9 a little later -- after finding a naked 9 elsewhere -- but didn't notice the single 8 remaining, and only placed it much later. It may have made the puzzle harder for me.

I decided before watching the video, I was going to give it a try. Quickly it boiled down to looking for cells with only three digits. I hate this part. It's so slooooooooow. After plunking along for 30 minutes or so, I was ready to give up and humbly bow before the master and say I wasn't good enough, but, out of the blue, I saw that y-wing and hope was renewed. It only took another half hour to finish the puzzle and the only reason I finished so quickly was I have been faithfully watching Mark and Simon everyday for the last nine months and doing at least two puzzles a day. Yeah, it took an hour, but nine months ago, I couldn't even begin. Mark and Simon, salute!

This puzzle is a delight to do without using any pencil marking. It took me sometime to get started and, being a rather slow player, it took me 25 minutes and a hal f to do it. Restrictions around box 9 allows you to figure the 7 must be in row 8, thus being restricted to r7c2, you end up seeing that row 1 becomes the Achylleus' heel of this puzzle, which can be completed easily, the rest falls into place rather easily.
