Xtreme Ziplining
(Eingestellt am 11. November 2023, 20:04 Uhr von gdc)
This puzzle combines Zipper Lines (ruleset form Jaze) with X-sums. Thanks flinty for that idea and users on the CtC-fan-discord for testing. The puzzle is meant to be relatively approachable. However, If you've never seen Zipper Lines before, I'd recommend solving Zip-a-De-Doo-Dah first.
- Normal sudoku rules apply.
- X-Sums: Digits in tabs (outside the grid) indicate the sum of the first N digits looking into the grid in the row/column, where N is the first digit seen. For example: If the tab above column 2 contained an 8, the column could start with 2 and 6.
- Zipper Lines: Digits an equal distance from the circled center of a line sum to the central digit.
Example Puzzle
Here is a 4 by 4 example from Jaze (left) and it's solution (right). Notice how the ends of each line sum to the digit in the center of the line. Additionally, the long line also contains two more sums 4=1+3=1+3=2+2. You can play the example here.

Wow! That was phenomenal. As I started, I wasn’t sure if I was going to break in, and then I started to put things together and it all flowed very quickly. That was a lot of fun and quite satisfying. Thanks so much!

Brilliant puzzle. I especially liked the interactions across the grid.

This puzzle deserves a lot more than 4 solves. :(
It's far more approachable than perhaps some folk are thinking? I hope this comment convinces a few more people to give it a go.

Interesting interaction between xsums and zipper lines. I would love to see more mixing between zipper lines and other kind of lines
