Suguru Chaos Deconstruction #3: Whispering Palindromes
(Published on 20. February 2022, 16:27 by mathpesto)
This puzzle is the third in a series, and I think it's harder than the other two, so I'd recommend first trying out "Suguru Chaos Deconstruction" and "Suguru Chaos Deconstruction #2: Kropki Edition". If you're stuck, check out the walkthrough of the solution below. Hope you enjoy!
Rules:
Fill some cells in the grid with the digits 1–9 such that no digit repeats in a row or column. Cells with a line or circle must have a digit in them.
Cells with a gray circle contain an odd digit. The sequence of digits on a gray line must read the same forwards as backwards. Adjacent digits on a green line have a difference of at least 5.
All digits must belong to a region, which is a collection of orthogonally connected cells. A region of size n contains the digits 1 through n once each. Regions may not touch each other orthogonally, although they may touch each other diagonally.
SPOILER ALERT Walkthrough of Solution
Puzzle:
Solution code: Ignoring blank cells, write the digits in Rows 1 and 2 (left to right, no spaces)

I'm a latecomer but have fallen in love with this series. :) This felt like the most hardwon victory. I love how the region-discovery phase was set up so much differently from the first two. Thank you for making these!

A real tough one, and a lot of fun to solve at the end :)

I thought I made a mistake bc I got a deadly pattern at the very end but it turns out the german whispers line on R3C9-R4C8 doesn't appear/is covered by the palindrome line on the CtC link
--------
@derKrampus: Thank you for pointing that out! It must've gotten messed up when CtC software made an update. I've provided a new link.

These are highly addictive. I've done four now and I think this was the hardest, but I got there via some very clever logic, thanks.

Fun, fun, fun. I didn't find it too difficult, but it did take me a bit longer than the first two puzzles in the series.

I actually found this one about as difficult as the second of your Suguru Chaos Deconstructions, but even more elegant. I really liked the role of the palindromes in this puzzle. Thanks a lot for setting it, mathpesto!

@Phistomefel: Thank you so much for solving another one of my puzzles and for your kind words! Be on the lookout for my fourth installment in the series soon ;-)

Clarified rules to explicitly state all digits must belong to a region.

I played this puzzle some time ago and wanted to leave a rating sooner but i had isues logging in. Anyways this puzzle just like the other 2 was fantastic although this one was way harder in my opinion and i even made a mistake along the way causing me to stress out if i would even be able to complete it. but aventually i did it yet a gain a nice puzzle

@Jjesper, thank you! That means so much that you came back to leave a rating. And I'm glad you persevered and were able to solve it!

Great puzzle again! The logics are all reasonable; the most difficult part for me is to do scanning on this really large grid :p

Wonderful puzzle again. I loved it.

Starts easy, then becomes monstrously hard.

Again, very nice and enjoyable puzzle! Definitely a bit more difficult than the first two, though I would personally say four stars rather than five.
