BLACK DOTS: If a black dot sits between two digits, one is double the other.
GREEN DOTS: If a green dot sits between two digits, they have a difference of at least 5.

That was incredibly beautiful! The logic was intricate, but just flowed.
It was shockingly easy for me somehow (maybe because I just recently solved the Rat Run finale), so if I didn't know better, I'd have rated it 2*, but it's clearly a 2.5-3* puzzle.
I love that there were no "tricky" steps: each step flowed very beautifully if you just asked the right question, and the right question was always totally obvious in retrospect.
Thank you Marty for yet another magnificent puzzle!

Really enjoyed this one and had fresh logic which I really like it and hope others do something like this in the future.

Whew! Didn't think I was going to solve this one, even after I had (I think) all the right insights.
With a bit too much "pretty sure" instead of "definitely", I managed to finish it, though.
Difficulty 4 stars for me.

While the puzzle can be finished very quickly once you have the right insights, it is a very tricky and beautiful puzzle.

Very nice and exceptionally smooth, as expected from a masterful setter, thanks!

I was stumped on this overnight but once I asked the right question it came together very nicely. Fantastic fun as always.

Beautiful how the geometry just sinks into itself at the end
