I found the swordfish. I found the X Wing. I found the Skyscraper. I found the finned X Wings. I found the triples and the pairs. I found the Y Wings. I STILL had to bifurcate.

Took me about 40 minutes. Swordfish? No, didn't even know what that was till this video. Even missed the Xwing. So, what did I do? Bifurcate, and click undo like a monkey; bifurcate again. Repeat. About 5 bifurcations did do the trick. This works ok on-line, cannot do it this way with a pencil+paper sudoku. Not sure I would even want to deploy a swordfish after seeing this, but the bent triples were cool.

Derek Neil's puzzles in the Classic Sudoku app really did prepare me for this one!

There are lots of extreme sudoku possibilities out there, but they wouldn't be fun as you would just have to plough through endless logical chains (or simply resort to trial and error). Derek's puzzle is much better, as it is solvable with techniques relying on recognising typical pattern, and not just endless variants until you can rule out single digits.

@@blobblub9424 Mark sometimes does this thing where he plugs a number in somewhere and follows the ramifications of that placement to see if it causes problems elsewhere so that he may eliminate that possibility. It is incredibly hard to follow and even harder to do yourself. What it allows Mark to do, however, is get to a solution faster without having to figure out the logical path to the solution which may be fairly narrow and hard to figure out. My comment was an allusion to the fact that I can neither figure out the logic like Simon nor bifurcate like Mark. Especially not on a beastly puzzle like this.

It took me 4 hours 44 minutes, and I took a few hints from the comments to be aware of what to look out for, but I'm proud that i was able to finish it. It was very extremely hard going, but unusually not particularly frustrating this time. Maybe it's because I knew it would be a devil before I went in. I think it's been a good one for teaching me how to spot patterns, especially the y-wing.

That was incredible! I wish I had brains like that 😅

I entered the puzzle in "heart sudoku", a sudoku app for macos, which can highlight the pencilmarks for a selected number. This helped me to spot some patterns... so the solve was successful, but a little bit cheated because of the highlighting. Without that - no chance for me... Good job Simon!

34:23 - I can see it, Simon! I can't believe it, but I can see it. Top right hand square. In four squares, you know it's (1,4), (1,3,4), (5,6) and (3,5,6) sort of going clockwise, but NONE of those squares can hold a Budgerigar. So there's a Budgerigar in the square above the nine, and yes, I'm being silly. (It's clearly a crocodile).

After doing all the simple standard tricks, I went straight to following Ariadne's thread over and over, like I usually do. There were very few times where I found a breakthrough that afforded me several digits. Most times it only resulted in being able to erase one pencil mark, and then right back to following threads again. It was like that all the way to the end. Nothing ever really "broke the puzzle open". It took me 3 hours, not using any advanced techniques. It was like death by a thousand cuts, but it sure felt good when I finally finished. That was my kind of FUN!

i got it in about 2 hours :d i recognized number patterns to help me with some numbers, though it also set me back when i thought i saw one pattern that was just a trap, i thought i'd finish in 20minutes and it stretched me out for another hour before i realized it great video
