Moon-or-Sun + Magnets Hybrid:
Place several magnets into the grid. A magnet consists of a 1x2 domino and has a positive and negative pole. Both poles of a magnet are always contained within a single region. Each region must contain at least one magnet. Equal poles can't share an edge.
Additionally draw a loop that travels orthogonally through the centers of some cells. The loop cannot branch off or cross itself and visits every region exactly once. Within a region the loop must pass through only positive or negative poles and all instances of them within the region.
The loop may not pass through the same type of poles in two consecutively visited regions.
The numbers around the grid (if given) indicate the number of positive/negative poles that are visited by the loop in that row/column.
Solution code: For each row the number of turns the path takes in that row (11 digits total)
