9-steps Tutorial: Zipper Line
Here is a tutorial sudoku teaching the zipper line constraint and aimed at first-timers. It is accessible, though not the easiest puzzle. When following the steps, it is build to showcase some common logic of this line type. However, if you feel like it, or for more experienced solvers, feel free to solve it any way you like, there are no rules! (Except the following...)
Rules: Normal sudoku rules. Along a lavender zipper line, any pair of digits that are the same distance from the centre of the line (marked by a spot) sum to the same total. For odd length lines, the total is the central digit.

Last puzzle in the serie: Little Killer
Solution code: Bottom row, left to right

Thank so much everybody for all the nice comments!
@gdc: Thanks, I'll find some time to adapt the visuals. I couldn't find a predefined style on the setting apps. I just tried to guess.
@Bulkystapler: Feel free to contact me on the CtC discord if you want help

@bulkystapler the CTC app doesn't have a solution programmed, it is only checking for sudoku errors, so you've likely made a msitake with one of the lines not adding up correctly.
Puzzle's a good intro to the rule, only just above gas level in difficulty.

Thanks for the excellent zipper line puzzle

I've had trouble withn this one. The CTC app gives me the solution as correct, but the solution code won't confirm that.

Very nice setting! Sometimes I feel constructors only use zipper lines for fairly challenging puzzles although the ruleset can also be used in a very beginner-friendly way as demonstrated here. Glad to see even zippers were mixed in as well.

@haligonian: Thanks a lot! It is exactly the difficulty I was going for :) Glad you liked it!

This was a fun intro to zipper lines. I had to work out a couple of fun things that are probably universal to this type of clue.
It was easy, but not *easy*. A 1.5/5 if you've not done zipper lines, 1/5 if you have, in my opinion.
Thanks for setting!
