Incomplete Squares (Zipper Lines)
(Published on 28. October 2023, 20:36 by gdc)
I can't get enough from the new Zipper Lines ruleset from Jaze and hope you do too. This one is meant as an introduction-puzzle suitable for solvers who have never seen this line-type before. Enjoy!
- Normal sudoku rules apply.
- Digits an equal distance from the center of a lavender 'Zipper Line' must sum to the digit in the middle of that line.

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.
Do you want to solve more?
Solution code: Row 1 (9 digits)

Lovely puzzle. Simple enough but perhaps simpler for having now solved other zipper puzzles. I think this may have been the one where my head confused me a month ago about how lines worked!

Took me nearly half an hour, simply because I forgot about basic sudoku for a moment :). This new ruleset is fun!

Very nice puzzle! Would also make a great puzzle for anyone who hasn't tried Zipper logic before.
