I was a little slow to pick up on something obvious, so took me just over 20 minutes. Really enjoyed it!!

Took me ~2.5 hours over two days, but I have finished it. Amazing puzzle. I got slipped up on a couple bits of logic, but I think it's a very nice puzzle. Definitely 2/5 for me.

I rated this 1/5 difficulty
Another great puzzle in the series!
As @sujoyku mentioned, the geometry was wonderful - and there were a lot of nice ideas throughout the solve.
I felt like the puzzle was quite approachable and was engaging throughout. Each of the logical steps were fair and reasonably straightforward to spot/utilize.
I typically don't rate the puzzles in this series as 1* since they often utilize the phistomefel ring (an advanced technique) - but this puzzle doesn't seem to require using the set equivalence (and the logic was all straightforward IMO).
I "technically" used the ring equivalence in the break-in, but my "use" of it was limited to just simplify preliminary candidate pencilmarks. As soon as a began really "solving", all of my actual logic for eliminating and placing digits on the ring was found using basic geometric tricks that are fairly common/straightforward. The logic for placing the initial candidates can be derived using the exact same geometries - so a beginner or intermediate should have no issue solving this without any prior knowledge of the ring.
Either way, the solve was very nice and quite approachable. Thanks for sharing!
