Wavy Zippers
(Eingestellt am 19. Dezember 2023, 23:15 Uhr von ViKingPrime)
PUZZLE:
RULES:
Normal Sudoku rules apply.
• Entropic (beige): Each set of three consecutive cells on an Entropic line must contain a digit of each size - low {1, 2 or 3}, medium {4, 5 or 6} and high {7, 8 or 9}.
• Modular (teal): Each set of three consecutive cells on a Modular line must have digits each with a different remainder when divided by 3 - remainder one {1, 4 or 7}, two {2, 5 or 8} and zero {3, 6 or 9}.
MODIFIER:
• 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:
Zipper lines are more popular than Renbans now; I don't know which will go first — Sudoku or consecutive groups of digits arranged in any order.
If you're familiar with Entropic and/or Modular lines, this may feel a bit easier; whereas if this is your first puzzle with these lines, this may feel a bit more challenging. I hope you'll forgive me either way, as (in my opinion) the logic here unfolds rather prettily.
Have fun!

Had to spend a couple minutes to think about what effect mod3 and entropy has on zipper lines, after that the puzzle solved very smoothly, nice construction!

Brilliant puzzle! After quite a hard break-in, the puzzle became super smooth. Thank you

After an initial realization about the lines, this is very smooth and sweet!

Took a while to realise how restricting zipper&modular/entropic is.
Lovely pieces of logic throughout

Well modularity is definitely not my strong point, and I did find it confusing switching between entropy and modularity, and made a few silly mistakes because of that.
But this is a brilliant construction, loads of really cool interplay between the two rules. And I like how there are some embedded unwritten rules to find and learn too.
Particularly enjoyed one early deduction on the bottom-right modular line, and then again later found it very satisfying how it got finally disambiguated.
Lovely titbits of logic running all the way through, and a stunningly elegant grid aesthetically too. LOVE how every zipper is a right angle without exeption. One of my favourites of yours, top class stuff

A stunning setting and a really smooth flow! You are a constructing machine right now!
