Chaos Construction: Numbered Rooms / Skyscraper / Sandwich Length
(Published on 4. May 2022, 07:54 by KNT)
A clue outside the grid can mean one of three things, as written below.
1. A clue outside the grid indicates the number which has to be placed in the Nth cell in the corresponding direction, where N is the number placed closest to the clue. Both the indexing number and the indexed number are in the same region.
2. Treat each number N as a building of height N. A clue outside the grid indicates the number of buildings seen from from that direction, where taller buildings hide shorter buildings. Each seen building is in a different region.
3. A clue outside the grid indicates the number of cells between the 1 and the 9 in that row or column. The numbers between the 1 and the 9 in that row or column are all in the same region, and that region does not include either the 1 or the 9 in the respective row or column.
Solution code: Type the digits (no spaces) of the region containing R8C4 as follows: Row 1's digit in the region (left to right), Row 2's digits in the region (left to right), etc. 9 digits total.

The clues on column 7 should be on column 8.

Tackling this almost two years after publishing - as part of a tour of older CC puzzles. Immensely enjoyable!

Very fun and interesting puzzle.
Complex ruleset, which required thinking about all the different clue types.
Impressive that you can set a puzzle like this at all, especially with only 1 given.
Not too hard either, once you get started.

Another beauty, thanks. KNT's puzzles tend to fry my brain, though they're worth frying one's brains for. I thought I'd broken this at least 3 times when I hadn't.

Loads of fun! Thanks!

Another piece of art with a ruleset that might seem too intricate at first, but once you get used to check-eliminate the wrong options, it makes for a great ride of deductions ! Many thanks again !

Great puzzle! Lots of beautiful deductions throughout.

Excellent Puzzle. Beautiful Logic. Some steps were really hard, but still fair in my opinion.

Very nice inspiration after Thonk, definitely both puzzles are fantastic!

Fantastic! Fun puzzle with consistent difficulty and a nice mix of different logic.

Thanks, Marc. Means a lot coming from you because from what I can tell you're a much harsher critic than most :-)
I am not sure if that's true but I certainly get less attracted by puzzles with the same variations on the same themes. Your puzzles (as well as those of some other of my favorite setters) do enter a class apart. I'll keep an eye on your posts.

Nice puzzle! Unfortunately it was unclear to me how to read the rules: I thought "one clue type from (rooms, skyscrapers, sandwich), and then given a clue the corresponding region constraint holds". After a contradiction I realised that the region contraints were included in the "one of the three holds"

Thank you, Siebuhh! I'm sorry the rules seemed confusing to you, but even after rereading them, I think the precision of wording conveys what I intended.

Very nice puzzle! There are some beautiful deductions in the solution path.

Thank you, kolot! I had a lot of fun figuring out different things with this ruleset. I honestly think I could make 10+ more puzzles with it, each that use different ideas.

I got the idea for this puzzle about 2 weeks ago when I saw "Thonk" by purpl posted in the CTC server. I thought the ruleset was interesting, and got the idea to turn it into a chaos construction (I have not actually solved "Thonk", I just saw the ruleset and got inspired. Sorry, purpl).
I immediately found it almost impossible to force any sort of break-in without loads of givens, and about a week ago I made a puzzle with this ruleset with 7 givens. I was determined to get it down to 4 givens, and after a few more days I reached that goal. After talking to a few people about the ruleset, I got new insight that eventually birthed the 1-given holy grail of a puzzle you see here.
While you might not find this the most difficult, or the most fun of all my puzzles, I am very proud of this one because from a setting point of view this was extremely hard for me to execute.
Anyway, if anyone solves this and is interested, I have 2 other puzzles (one with 6 givens, one with 3 givens) that use a similar break-in idea, but have wildly different back-two-thirds of the solve. I am happy to send them if you send me a message- I am in the CTC discord server. Albeit while I don't think either is worth posting here when this puzzle exists, they do have some interesting ideas I was unable to explore with this one.
