Just seen this now, very interesting puzzle! Very satisfying to find the implication of the rules.
- I'm glad you saw it and found it interesting! I’d say it’s maybe a bit more difficult than yours, but it was heavily inspired by your puzzle, so thanks for the spark!

I didn't fully grasp the real implications of the lines at first, but once I grouped certain cases together, the puzzle only started to unfold itself and it got easier after that. Still, that was a neat and interesting discovery overall! :)
- Thanks for your comment! Yes, that was the intention to make it easier once the lines and the implications of the constraints together are fully understood.

Very cool, took a bit of time to figure out how the constraints worked together and then it was pretty smooth. Thanks!
- Thanks for your feedback and I'm glad it was smooth after the break-in.
