Suguru Chaos Deconstruction: Zipper Lines
(Published on 24. December 2023, 04:34 by ONeill)
Deconstruction: Fill some cells in the grid with the digits 1–9 such that no digit repeats in a row or column. All digits must belong to a region (a collection of orthogonally connected cells), and 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.
Zipper Lines: Digits an equal distance from the centre of a green Zipper Line sum to the digit in the middle of that line.
Cells with a circle contain an odd digit. Cells with a square contain an even digit.
All cells with a clue contain a digit.
The puzzle:
SudokuPad
Solution code: Ignoring empty cells, the digits in Column 7, followed by the digits in Row 13

Abandoned this several times earlier, always getting stuck in the endgame, but finally managed to get thru this time. Very ingenious, and fun. Thanks, @ ONeill :).

It’s a fun puzzle! Very hard but flows really nicely once the little nuggets of logic are found. Thanks for sharing this delightful puzzle.

What an absolutely gorgeous work of art. I kept getting blocked, and then finding a small break that would keep me invigorated. Next thing I knew I had been sitting in one spot for over 2 hours and had a masterful work of art completed in front of me. I couldn't help but stare at it. Easily one of my favorite puzzles, bar none!
