Ignoring the 7 in Box nine blatantly *staring* at the 5/7 pair in Box seven is such a Simon thing to do :D

@RichSmith77 10 ай бұрын

His whole method of haphazardly removing pencil marks once he had completed the "thermo" in c9 was so frustrating. Anyone else would go down, line by line, cleaning the pencil marks down the grid. Not Simon. Proceeds to remove one of the two 8s in row 8, one of the two 7s in row 7, (pause), one of the two 2s in row 2, (long distraction), removes the other 2, removes *both* 3s in row 3 (great!), removes a 9 from r7c7 (good), removes a 3 from r7c3 while ignoring 7 looking at the same cell (oh dear)... Admits at this point, this is why he doesn't like pencil marking so extensively. "I'm just rubbish at it". Yep. We can tell. 🙂 At least he finished off by tidying up box 5 efficiently.

This puzzle is a perfect example of Dorlir’s outside the box thinking, and unstoppable urge to create minimal looking grids with lots of juicy hidden logic inside. It amazes me how he keeps being successful in this endeavour, and this gem has to be one of his best and most surprising creations / discoveries yet. My favourite part was realising that the shaded cells in box 2 could only escape via box 1. Fantastic solve from Simon too, who grasped the logic almost immediately.

A trick I noticed: You have a pencil-marked 5 in R4C5, but that cell can never be a 5. A 5 in row 4 must be unshaded, but as it is also in box 5 it must be shaded. How can a cell be both shaded and unshaded at the same time? It can't.

Yeah I noticed that early and was trying to see if it would apply elsewhere, but it ended up not being a very generalizable trick. There are very few digits where this thought process could be useful.

Fascinating puzzle! At first I misread the rules to say that the rule applied to row, box, *and column* N, and after a minute ran into a contradiction in box 7. Fortunately, I ran into the issue quickly. It would have been awful if I had gotten 20 minutes into the puzzle before discovering my mistake.

Somewhere around 25 minutes in, you made an assumption that the 12 domino in box 2 was on the left, when it could possibly have been in the middle and connected to a 5. I skipped to the end to see whether you were right and you never checked. I had assumed the middle and made several deductions before you did that, so I was quite taken aback. Edit: I feel so stupid now. I just realized there can't be a shaded 5 in row 4.

i had a brilliant deduction that simon missed. sadly it doesn't help the solve, but thought it was really beautiful. at 22:35, we get that the 5 is in 2 cells in box 5. the digit 5 in box 5 needs to be shaded, but in row 4 the 5 needs to be unshaded, so r4c5 can't be 5 or it would need to be both shaded and unshaded to satisfy the row and box requirements. that places the 5 in r6c5 and is shaded

I tried it, but I drew the entire shading first, looking for a way it could work, then started doing sudoku all over the place, did find row 9's thermometer that way, but was forced to put a digit on the parity line where it did not belong. When I undid the whole thing, I could see several places where I could still obtain the same total shaded cells in different places, but I couldn't quite figure out how to be certain. So I watched Simon do it instead, at least some of my skyscrapers were in somewhat the right place. Now I get to watch Simon again doing all kinds of otherworldly things in Chants of Sennaar.

It always felt like it would definitely be possible to see a next step if you scouted around enough.

Everything else was just getting to grips with how the row & box restrictions interacted until I got a digit on the red line, then I did an absolute ton of pencil marking 😅 I don't know if this was a 'hard' puzzle or just a case of looking in the right place for each logical step, but it's probably one of the most complicated solves I've managed to complete and I'm extremely proud of getting it done.

@Raven-Creations 9 ай бұрын

@ 14:56 - "there is a 1 that is shaded, and everything else is unshaded" - Your musings that follow are ridiculous. There is exactly one shaded cell in R1. You've just gone through at length how there can only be one or two runs of colour around the perimeter. Since there is only one shaded cell in R1, there are two colours in the perimeter. Given that R1C1 would be an isolated cell if it were shaded, R1C9 must be the shaded cell or you'd break the rule. All you're cell-by-cell logic extensions are just daft, since you can't have more than one shaded cell in the row. @ 30:09 - "I don't think I'm thinking about this clearly" - You're asking the wrong questions. Where does the unshaded 9 go in box 8? It must be in R7. If it were in R8, it would have to connect sideways, but there's already an 8 in the row. In box 7 you need unshaded 8 and 9. The diagonal is shaded, so the cells below the diagonal must be shaded or they can't get out. The 8 and 9 in box 7 must be vertically to connect, so they must be on the perimeter, which makes the rest of the perimeter unshaded. You know which is 8 and which is 9. You now have a resolved 15 pair on the diagonals in R7. The 9 in box 8 must connect to an 8 above it, making R4C4=6 and R4C6=2 (shaded). In C1, similar logic to the shaded cells in C9 applies, putting 1 in R9, and 2-9 in order vertically. @ 43:58 - Having just claimed you can put 12 into R5C7/8. Actually you can't. If you do that, the 9 in the box must connect sideways to 8 in box 5, which connects vertically to 9 in box 8. This then has to connect to 7 in R5C6, 9 in the centre and now you have no more high digits to connect with, and you need at least one more. In addition, you'd have a stranded 12 pair in the box. You didn't need to use yin yang trickery; during my own solve, there was never a checkerboard possibility.

@Steev42 10 ай бұрын

Christ. I spent way too long (well over an hour) trying to figure out how box 2 escaped, eventually by basically brute force realizing the shaded 5 in box 5 had to be on the bottom, thus preventing a 1-2-5 vertically in the middle from box 2 to box 5. Never even dawned on me that 5 couldn't be shaded in row 4. Amazing how missing one little thing can make a puzzle so much harder.

Because in row 7 the digits 1-7 need to be shaded. Also in box 8 the digits 1-8 need to be shaded. So the only digit in box 8 that's unshaded is the 9.

I don't think you can assume the c9 thermometer. Consider a 1 in r2c3 and r3c4 with a 2 in r2c4. This leads to the 2 and 3 being reverse in c9. Similar can be done with 8,9 in boxes 7/8.

You can’t put a shaded three in row 2

I was thinking the same, but that's surely why the rule for row N is included

I wonder if it’s called parity cave because the shading looks kind of like stalagmites in caves after the puzzle is finished

No, it's because the rules are very similar to a type of pencil puzzle called cave puzzles.

Ropes can be straight or interlaced. Braids weave.

The strands that make up a rope twist. You just need to imagine you're looking at one side of a three dimensional rope. The strands disappear off the left (column1), go round behind, and re-emerge on the right (column 3).
