Rules:
Draw two loops. Each loop is orthogonal, non-intersecting, and goes through the centers of some cells. Each loop passes through every region exactly once. For each pair of orthogonally adjacent cells across a border, at least one of them must be visited by at least one loop. The two loops may not overlap each other nor turn at a shared cell; however, they may intersect perpendicularly. Two clues in a region (if given) represent the amount of cells visited by each loop. A “?” represents a positive integer, and two “?”’s within the same region have the same value. The order in which a pair of clues appear is arbitrary.
Solve online:
Penpa (For answer check to work, both loops must be in green.)
SudokuPad (Does not have an answer check.)
Solution code: Number of cells not visited by either loop in Row 1, then Row 2, etc. (10 numbers, no spaces)

took me a while to fully understand the implications to the rules but once i did it was a phenomenal solve :)
