Chaos Construction: Killer

(Eingestellt am 4. April 2022, 23:31 Uhr von KNT)

Normal Chaos Construction rules apply. Place one of each digit 1-9 in every row, column, and region, but the regions must be determined by the solver. That is, divide the grid into 9 orthogonally connected groups of 9 cells.

Digits in a cage must sum to the value in the top left corner of the cage. Every cage is entirely contained within one region. That is, for any cage, no two cells within that cage belong to different regions.

After a flurry of chaos constructions, this should be my last one for a short while, but I am particularly proud of this, more than the rest I have made. I think the difficulty is somewhere between 4 and 5 stars, but I am posting it at 5 to signify it is harder than my other 4 star puzzles. I hope you enjoy this one as much as I enjoyed setting it!

Lösungscode: Type the digits (no spaces) of the region containing R1C9 as follows: Row 1's digit in the region (left to right), Row 2's digits in the region (left to right), etc. Then do the same for the region containing R9C1. 18 digits total.

Very nice CC with killer cages. Really nice deductions involving the columns. I particularly liked the one that forced 2 cages to be in different regions because of one digit. So cool. Thanks++

My favourite of your puzzle so far. So many beautiful deductions throughout!

Took me an hour to get it done, only to find a deadly pattern at the very end haha. Then another 10 minutes to see my error. Really nice!

That was fun to solve, thank you for setting this :)

Thanks TNC! I can’t lie, your puzzle Tight Fit definitely inspired me to try making a puzzle with this ruleset. I’ve been solving for a long time, but only started setting about 2 weeks ago, really with the purpose of making puzzles of rulesets that I personally enjoyed. I think this ruleset in particular is heavily underutilized for chaos constructions- it’s a ton of fun!

————

I agree, I think what's missing is an easier puzzle with this ruleset since mine was 5/5 difficulty as well :)

It's always amazing to see something inspired by my puzzle, it feels like I created something more than just a sudoku

Hm. During my various attempts, the puzzle seemed really brutal, but once I solved it, everything suddenly seemed obvious and easy to spot. Very odd! ;-)

————

I think similarly! It’s all about asking the right questions at the right time. I’m glad you enjoyed it!

Lovely puzzle! That was too hard but very satisfying.

————

I’m glad you enjoyed it! Too hard? Aside from one step (that i mentioned to cdwg in a hidden comment), I felt everything was not monstrously difficult. Nevertheless, I am very happy with how this puzzle turned out.

Right, it is not monstrously hard but there was one step (which is not the one you mentioned) which took me a long time to spot. That step may not be hard for others, but I just couldn’t see it quickly.

——

If you don’t mind, can you write which in a hidden comment? I truly am curious. Once again thank you for the solve!

Very nice! Some beautiful but not easy to spot steps.
