Concealed Zippers
(Published on 10. January 2024, 23:01 by ViKingPrime)
PUZZLE:
RULES:
Normal Sudoku rules apply.
Normal Chinese Whisper, Entropic, Modular, Nabner, Parity, Region Sum and Renban line rules apply
(full explanation for each line is within the puzzle link).
MODIFIER:
• Line Ambiguity: Each line has its own unique identity, to be deduced by the solver (e.g. the Nabner line could also function as a valid Entropic line but will still be identifiable as the Nabner line).
• Zippermania: Each line also acts as a Zipper line, wherein digits an equal distance from the center must sum to the digit in the middle of that line.
INTRODUCTION:
I thought this may be the final entry in the series but as gdc has pointed out, this is not nearly the challenge needed for a grand finale; expect another (much more challenging) entry sometime in the future.
Here are some puzzles from other setters using the same constraint:
"Flipping the Zipped" by SSG

Really excellent setting and a rewarding puzzle to solve. It's surprising this could be easier than the previous "Exposed" puzzle. But it's still quite a challenge! I spent many minutes staring at it, wondering how there could possibly be enough information in those few grey lines.

Super smooth and enjoyable. When I said, this is not suitable as 'the big finale', I was commenting on the difficulty which I think could be higher with that much buildup. The quality and elegance here is great!

This is an amazing construction. Staggering that VKP was able to take 7 familiar line constraints, and arrange them so neatly without any kinks or twisty bits, just 6 straight lines and one right angle, to lead to such a rich and fun solve path.
Not his hardest puzzle, but in my mind that is a good thing :D It certainly wasn't trivial, there was lots to consider at the start... this was a perfect difficulty level for me.
Lovely stuff, this puzzle oozes elegance
