Normal sudoku rules apply.
Arrows: Digits along an arrow sum to the digit in the arrow's circle. Digits may repeat along an arrow if permitted by other rules.
10-Lines: A red line can be divided into one or more non-overlapping segments whose digits must sum to 10.
Digits may not repeat along a line.

I like the extra constraint on the 10 lines, it makes it more approachable. The break in was very nice.

level 3.
not because the logic is itself very hard, but because you need considerable experience before you can even begin to identify what to study.

Did you invent this 10-Lines? This is my first time encountering it, I really like it!
========================================
Thanks for solving! 10-lines are somewhat new but there should be loads more of them for you to try out :D

The non-repeating 10 lines are really fun to work with.
