Along green loops, adjacent digits differ by 5 or more.
Pink loops contain a non-repeating set of contiguous digits in any order.
Digits separated by X sum to 10; ALL possible X’s are shown.

Thank you very much for creating this puzzle. I love negative constraints

One of the best 1* puzzles I have seen in a while!

I forgot about the negative constraint

Great puzzle. Fun coloring! I didn't have to use the negative constraint at all. Perhaps because I used Phistomofel?

Presumably people got hung up colouring the X dominoes to use the negative constraint since it looks like that type of puzzle, that's how I started. But the negative constraint doesn't actually resolve much here, just a few small disambiguations. I abandoned that colouring quickly and just ended up colouring for highs and lows. No letters required.
You could also potentially take a huge short-cut with the Phistomophel ring and solve it in ~10 minutes but I didn't use that since it's a 1* puzzle. Interesting puzzle though, not trivial but definitely 1*.

Really nice letter solving. No coloring here, that just gets confusing! I do wonder why solvers try to use colors though...

I actually found it quite easy but think I may have got lucky and clocked the path quite early. No elaborate colouring needed, once you've established the 456 positions it's just a small jump to figure out highs and lows.

Fun coloring puzzle, closer to 2 stars for me based on time it took to color the grid. Thanks for sharing

Probably in that 1.5 star range, I went for a 2 because I used full colours and letters to solve and whilst a familiar concept for an experienced solver I think its beyond a 1*

I love coloring, I love negative constraints, and while this is a terrific puzzle, I disagree with the 1 star rating. Took me a solid hour.
