Mad Zippers (Mad Fold-In)
(Published on 16. December 2024, 18:01 by gdc)
My third fold-in puzzle in a row! This time it is about zipper lines that become renbans when folded. Thanks to the testers. Hope you enjoy!
- Normal sudoku rules apply.
- Zipper: Digits an equal distance to the circled center of a zipper line sum to the central digit.
- Mad Fold-In: The dashed red lines are folded onto each other so that column 1, 2, 8 and 9 form a 4x9 grid. Lines act as renban lines in the folded grid.
- Renban: Digits along a renban line form a consecutive sequence in any order without repeats.

Terrific puzzle. Though I did find it closer to 4* difficulty.

Agree with ChinStrap! Love that the folded lines are totally different from the unfolded lines.

It is a very nice combination of logic, and the fact that there is 100% one set of rules on the folded and 100% of the other on the unfolded really gives it a transformative feel. Really fun!
