The elegance with which Simon can express his ideas so we can follow the logic is endlessly fascinating. I can never see the idea myself, but as soon as it's expressed the clarity of it is immutable.

I smile everytime Simon makes a brilliant mind jump to spot a difficult correlation but then overlooks a simple Sudoku conclusion. I just think it's beautiful how your mind can be so locked in to something complex, that it misses something obvious that you would have usually spotted right away, if you weren't distracted by your own mind. And by "you" i don't mean Simon in particular but all of us.

Instead of that 'bifurcation' method, you could have used that 13 cage logic that you've seen later. Asking if 49 can be in that cage would quickly give you answer 'NO' and after that you'll conclude that circle in box 3 can be only 9 (either 13 cage or box 9's circle will have to have 8 in them) To conclude that 13 can't have 49: this 49 forms x-wing with 22 cage and places 9 in r6c2, eliminating 9 from circle in box 7. 49 itself eliminated 9 from circle in box 3, but we need at least one 9 in those circles After placing one nine in the circle, nine from another circle is eliminated by simple 'visualization' of nines in the grid :)
@RichSmith77

Hmm. I also fixed r2c7 circle as being 9 first, the same way you describe. But it was far from a simple 'visualization' of where 9's could go in the grid to rule out 9 from r8c2 for me. I'm now wondering if I missed something, but I still don't see it. I still ended up chasing 9's then 1's around the grid, much like Simon did, only I fully bifurcated by writing digits into the grid.
@emilywilliams3237

I'm curious how 'visualization' differs from 'bifurcation'? I feel that I visualize all the time, and sometimes with some digits in the grid (or pencil markings to help me keep my place) - is that bifurcation or is it not? (Perhaps there are subtleties that I don't understand.)

I solved the puzzle, but was convinced I'd bifurcated my way to a solution. I said to myself, ok, let's see how it should have been solved by watching Simon. I'm slightly shocked that Simon basically found the same logical chain I'd discovered, to rule out two 9's in circles, albeit he did it all in his head, whereas I wrote digits into the grid. I guess my solve wasn't so bad after all.

I finished in 126 minutes. Despite the trick being simple in nature, I struggled so hard to find it. I finally was able to prove that two 9s couldn't be in r2c7 and r8c2 thanks to box 9 and 6 limiting 9s as well as the 22 cage, which had to have a 9, breaking in box 4. That was not easy to see. It took me 90 minutes to do that. Then, it took me another 30 minutes to see the final trick, which I had already noticed way earlier as a possibility. That one involved the 8 arrow in r8c2. The arrow on the right couldn't be a 134, because it forces 34 into the 17 cage, which breaks it. This puzzle was fantastic, but those felt very hard to discover. Great Puzzle!

I came at the deduction of r2c7 and r8c2 not being 6s in a simpler way. 6 uses the digits 123 on a 3-cell arrow. Any 3-cell arrow needs two of the digits 123. If 6 were in either r2c7 or r8c2, then how does r2c2 respond to the correlating arrows? It would only be able to get 1 low digit on its arrow. That said, there's an even easier way to eliminate both 6 and 7 in r2c7 and r8c2. Both 6 and 7 only have one possible combination, 123 and 124 respectively. This would make either r2 or c2 in b1 the 123 or 124, and that is impossible.

20:44 this different way of seeing it is in fact circular logic, since you used the fact that 1s are on the arrows, which is deduced from r2c2 not being 9 (which is exactly from r2c7 and r8c2 containing at least one 9, seeing the cell)

found the breakin unsatisfying here, so tried to find something more straightforward. starting from the state of the grid at 33:11... we know both of the box 1 arrows must have a 1, and they either go in r3c2 and the domino in box 2, or r2c3 and the domino in box 4. in the former case, we have a 234 in row 3, and a 1 in r1c7. in the latter case (which is symmetric), we have a 234 in column 3, and a 1 in r7c1. either way, there's a 1 that sees r7c7, so we can eliminate that 1. that confines the 1 in box 9 into a domino in column 8, so there can't be a 9 in the 10-cage. now a 9 in both circles (boxes 3 and 7) would put a 9 in r9c6 and also in r6c9. but this eliminates 9 entirely from box 9. so they must be an 89 pair. it's still a little obtuse, but the symmetry makes it feel less like trial and error. wish i could see something a little more straightforward.

But I would recommend going through the older videos on the channel and try out the puzzles from some of the shorter videos (say, less than thirty minutes) They tend to be easier, and if you get stuck you can follow along with the video! Personally I did quite a few of the shorter fog-of-war puzzles - because the grid is partially covered it can be easier to know where to look next! Happy solving!
