## Zipper or Ziffer?

(Eingestellt am 26. November 2023, 02:06 Uhr von marty_sears)

Was an absolute pleasure creating this puzzle with ViKingPrime and ThePedallingPianist. We are all big fans of Jaze's zipper line, and also ambiguity puzzles, so this seemed like a perfect thing for us to collaborate on.

Rules:

• Normal sudoku rules apply.
• GERMAN WHISPER LINES: Adjacent digits along a green line must have a difference of at least 5.
• Digits separated by an X sum to 10.
• For each purple line it must be determined whether it's a Zipper line or a Ziffer line.
• ZIPPER LINES: Each pair of digits an equal distance from the central spot on a Zipper line have the same SUM, which appears on that central spot.
• ZIFFER LINES: Each pair of digits an equal distance from the central spot on a Ziffer line have the same DIFFERENCE, which appears on that central spot.

I was trying to find early ziffer puzzles and I tell you what it is hard to search for ziffer puzzles -- Ziffer means 'digit' in german, and it shows up often on german rules pages here! ai

what a puzzle! I'm glad I went back a few pages to find this gem. I find "must be determined" puzzles daunting, and this was no exception. In retrospect there was a bunch of clues to keep you going, and by the end the purple lines became my close friends. very fun!

Very nice puzzle! I sadly broke it 2 times but always came back with a nice „ahhhh“-Moment of what was overlooked initially. I found it more difficult but maybe I‘m not yet used to the Zipper logic :)

Enjoyed this a lot! The ruleset lends itself to some really interesting logic and the puzzle does a great job of showcasing it

Very nice ambiguity puzzle. It seemed quite busy to me at first but the pressure points were always visible. Liked the unexpected ways some of the logic unfolded and the whisper lines seem perfect to round out everything.
