The Big Zipper
(Published on 1. November 2023, 14:04 by marty_sears)
I really like Zipper lines, which were recently introduced by Jaze. So I thought I'd see how far I could push the idea, and made this :)
Rules:
- Normal sudoku rules apply.
- Along a lavender zipper line, any pair of digits that are the same distance from the centre cell of the line (marked by a spot) sum to the digit in that centre cell.

As jellef already wrote: you need a lot of tools. I’ve never used so many before... colors, letters, Xs, and circles. It was a wonderfully beautiful jumble. But I managed to keep track of everything. That was great.

A magnificent puzzle!
I had to guess a few 50-50's, with about half of these (predictably) leading to a broken grid! But I'm glad I kept going and got there in the end.
I will certainly come back to this wonderful creation and try to complete it cleanly.

Wow, this is a mind blowing puzzle. It requires a completely different way of solving, using pencil mark tools I never used before. But with the right tools, it's doable. Such a clever design!

My first zipper line puzzle. The break-in is lovely, and the main logic very enjoyable.

My first thought was „Oh no! Not another line rule!“ But now I think this one works great especially in such a wonderful executed setting. Thanks a lot for sharing this masterpiece.
