RULES:

---

Normal Sudoku rules apply.

• Parity (red): Digits along each Parity line must alternate between Odd and Even.
• Renban (pink): Digits along each Renban line form a set of consecutive, non-repeating digits in any order.
• Zipper (purple): Digits an equal distance from the center of a Zipper line must sum to the digit in the middle of that line

INTRODUCTION:

---

I think I might be up to my elbows in triangles for awhile; there's an incredible amount of pressure that Zipper lines can place on other constraints, which may be part of its charm. There's still so much line logic to explore (Entropy, Modular, Nabner, Tens, on and on and on..).

Here are some puzzles from other setters using the same constraint:
"It Began with a Zippy Smile" by gdc
"Zip-Tied and Locked in a Cage" by gUBBLOR

Have fun!
