Puzzlerium Tour: Dotchi Loop

 

 

Rules: Draw a single, non-intersecting loop, vertically or horizontally through the centers of the cells. The path of the loop never crosses itself, branches off, or goes through the same cell twice. The loop must go through all the cells with white circles. In each area enclosed by bold lines, the loop must either go straight through all the white circles or make a right-angled turn in all the white circles in the area. The loop cannot visit black circles.
