Quads Going On?
(Published on 21. May 2025, 14:07 by Fenners)
I've been setting some ambiguous clues lately and thought this could be an interesting concept. Quad circles or Anti-Quad circles? Plus some standard renban. Thanks to CtC Discord for testing and happy solving! Any comments greatly appreciated :)
