This is a Slitherlink on the real projective plane, with one extra rule:

  • The path that the loop makes must not contract to a point; equivalently, it must cross the colored lines that are glued in the cross-cap an odd number of times.

This was the puzzle I created for Secret Solver 2022 on the Puzzlers’ Club Discord server. Nowhere near as big a puzzle as my last go-round but I’m happy with it nonetheless. I’ve been quite busy, and not really had the time to dedicate to puzzles.

I procrastinated a lot on getting this up on my site, to the point I decided to rewrite the entire site first. Also, major thanks to chimpaznee for the gift I received!
