Normal Sudoku rules apply. Each gray line is BOTH a between line and a ten line:
Digits along a line must be strictly between digits in the circles at the ends.
Each line (including the end circles) consists of one or more contiguous groups of cells, each of which sums to 10. These groups of cells cannot overlap. Digits may repeat freely on lines and even within sums if allowed by other rules.
Happy HalloTwEeN!

If I didn't know better, I would say you are trying to appeal to me :) This was a lot of fun and very enjoyable.
