My brain can't, it seems, summon up any set theory, even when "understood" from past videos. Somehow, it was hard-ish, but I managed a solve without invocation of the Phistomephel ring, modified or otherwise.

Beautiful puzzle! Average difficulty if you are aware of the modified Phistomefel ring.

Quadruples are one of my favorite constraints, and the way this puzzle utilizes them is so cool. Instant add to favorites, here's hoping this puzzle finds its way to Simon.

That was a blast! It took me a while to wrap my head around it, but then once I did, I had a great time unravelling it.

A fantastic puzzle. Beautiful deductions throughout. I think quadruples are an underrated constraint, and this puzzle is a great example of how fun and powerful they can be. :)
