Chaos Deconstruction #2: Cave (11x11)

(Eingestellt am 6. Juli 2022, 07:57 Uhr von KNT)

And now a second entry to my Chaos Deconstruction series, and this time with maybe an even weirder ruleset than the last!

I set this puzzle (almost) start to finish on livestream in the CTC discord server! While this puzzle is primarily my creation, I want to say thanks to Niverio and TotallyNormalCat for helping out so that the end solve didn't break over and over again.

Rules:

1. Chaos deconstruction rules apply. In the 11x11 grid, nine 9-cell regions containing the digits 1-9 must be located. Digits cannot repeat any row, column or region, and regions are orthogonally connected.

2. A digit in a circled cell indicates the number of digits seen in all four orthogonal directions (including itself). Region borders obstruct vision.

3. The entire puzzle is a "cave" pencil puzzle, where filled cells are cave and empty cells are wall. In other words, every filled cell must be orthogonally connected, and every empty cell must be orthogonally connected to one of the edges of the grid. All circled cells and given digits are nonempty.

Play on Penpa+!

Lösungscode: Row 5 followed by Column 11, ignoring blank cells

Another doozy. Unlike some others I didn't struggle too much with the irregular bit, but it took me a while to spot some of the region building steps. Thanks!

Very nice - like all the other ones! ;-)

That was a fun way to spend time while flying! The ruleset was cool and there some neat tricky steps. The irregular sudoku at the end was tough for me, though.

Wonderful deconstruction. I found the irregular sudoku to be more difficult than the region building. Fun all the way through though!

Very nice! I was quite nervous toward the end, having broken it two or three times when I tried it last summer. Very relieved to finally have succeded :-)

Beautiful! I'll admit I was terrified at how few digits had been placed after all the clues were used, but the irregular logic was genuinely lovely. Thank you!

Awesome. Had to try it after the plug during the Memeristor interview. Thanks!

A very fine construction with a great balance of all the constraints. I totally understand why you said you had trouble figuring out the end solve, because it constantly felt like it was on the verge of breaking near the end with "almost deadly" patterns, and "naked singles" popping out of nowhere ! Cave logic was delightful and very powerful !

Superschönes Rätsel.
Sehr kniffelig, aber logisch zu lösen.

Absolutely wonderful! The integrated Cave puzzle really adds another dimension, requiring some logic not commonly used in Chaos Constructions.

Great puzzle. Thank you!

I'm glad you all enjoyed the puzzle!

Quite happy with how this one turned out given that it's probably the first puzzle in a very long time that I set start to finish in one sitting :)

Brilliant! Cave hybrids are always a lot of fun and this one worked wonderfully!

Got the break-in right away and never got stuck, nevertheless 4¼ difficulty.

Cannot wait to see more of these!

This puzzle took me 2 hours and completely destroyed my scanning abilities, but I did it! Very nice!

Wonderful rule-set! Great fun to solve :)

Really cool ruleset, and a fun challenge from start to finish! Even after finding all the regions the irregular sudoku didn't let up easily.
