On Repeat
(Published on 14. March 2022, 01:14 by mathpesto)
I decided to try and combine a few different rulesets from recent puzzles of mine: repeated digits in rows and columns from "Take Five (Away)", regions of varying sizes in a large grid from "Suguru Chaos Deconstruction", and arrows designating regions in a chaos construction from "Chaotic Arrows". Much gratitude to @Jesper, @myermian, @Plostoni, and @henrypijames for testing and providing great feedback on this one. I won't be posting walkthroughs of solutions like I had been doing, but feel free to post a hidden comment below if you'd like any help! :-) Hope you enjoy!
Rules:
Fill every cell in the grid with the digits 1–9 such that each digit appears at least once and at most twice per row, column, and region. Regions must be determined. The gray circle contains an odd digit. A digit cannot touch itself orthogonally nor diagonally. Digits along an arrow must sum to the digit in the circle. Digits along an arrow are part of the same region, and the digit in the corresponding circle is in a separate region.
Note: A region is a collection of orthogonally connected cells. Each cell belongs to exactly one region, regions may vary in size, and the number of regions must be determined.
Puzzle:
Solution code: Type the digits (no spaces) of the region containing R1C1 as follows: Row 1's digits in the region (left to right), Row 2's digits in the region (left to right), etc.

Tought but fair I think. Unusually complicated region building, but all good healthy fun, thanks.

Great puzzle! Enjoying your CC’s a lot. Thank you :)

Drawing for regions for half an hour after filling the digits: Never seen any chaos like this before.

Finally, a hoorah on this one, on the 3rd attempt!! Difficulty is 6* i think :) Enjoyed the marathon. Thanks, @ mathpesto :)

Großartig, vor allem nachdem ich meine ersten Denkfehler überwunden habe ;)
Great, especially after I got over my first thinking errors ;)

Wow, this one took me a while because I kept repeating the same wrong deduction at the top left part of the puzzle, which invariably led to a dead end... So I had to repeat, and repeat, and repeat again... But I've done it and it was so cool ! Really pretty interactions all over the grid, and much harder for me that your sequel puzzle "Repeater" ! Now I shall go back to the SCD series. Thanks.

That was so hard but equally so much fun. Thank you, mathpesto!
Also, I tend not to get hooked by chaos construction puzzles, but this one reeled me in from the get-go, which was a nice surprise.

@Mox: Thanks so much! Glad you enjoyed it!

Very hard, this is my favorite of your chaos construction puzzles.

Wonderful puzzle again! This one was the hardest of your CC puzzles. It was really challenging but fun.

Great puzzle! Cool ruleset with some new and interesting logic, and well balanced puzzle with a consistent level of difficulty throughout.

Very challenging, but really fun and interesting

I do find this version better than the first draft.
