Normal sudoku rules apply.
Summit Lines: Digits along a pale blue line must be ascending or descending, with 1 and 9 reversing the ascension/descension. (eg if digits along a pale blue line are 2-5-6-9-8-5, the sequence is ascending until the 9 causes a descension).
XV: Digits separated by an X sum to 10, and V to 5.

Solution code: Row 1

I found the rules confusing at first, but once I realised how they applied to the loops it made sense. I thought it was fun!

Pretty straightforward once you internalize the rules.

Much bigger restriction than I thought.

Took a little bit to get my head around the implications of the rules, but once it clicked it was a fun one. Thanks for it!
