Modular Zipper
(Published on 7. December 2023, 12:07 by gdc)
Since I've already put some modular arithmatic in the solve path of previous Zipper Lines puzzles, I now decided to directly use modular lines with zippers. Thanks Jaze and Fulldeck-Missing for coming up with those fantastic rulesets!
- Normal Sudoku rules apply.
- Any set of three sequential cells along a teal modular line contains one digit from (1,4,7), (2,5,8), and (3,6,9).
- Digits an equal distance from the center of a lavender 'Zipper Line' sum to the digit in the middle of that line.

Solution code: Column 4 (9 digits)

Some amazing discoveries at the intersection of sudoku lines and modular arithmetic here. Amazing construction. 4* for me though.
