Theme: Clue Symmetry and Logic

Author/Opus: This is the 3rd puzzle from guest contributor Takeya Saikachi.

Rules: Draw a route that starts at the gray Start circle (S) and passes through adjacent cells without crossing itself or revisiting any cells. Some cells may not be part of the route. White circles with letters represent packages that are to be picked up and delivered to the black circles marked with the same letter. The carrier has a maximum capacity of packages that can be handled at once, shown below the grid. The carrier must pick up and deliver all packages on the route, returning to S with no packages in hand.

Rules: Variation of Nanro and Nanro Signpost puzzles.

Label some cells with numbers to form a single connected group of labeled cells; no 2×2 group of cells may be fully labeled. Each bold region must contain at least one labeled cell. The small clue numbers indicate how many cells in that region are used. When two numbers are orthogonally adjacent across a region boundary, the numbers must be different. Each bolded region must be visited twice (i.e., have exactly two distinct connected groups inside it).

Also see this example:

Answer String: Enter the length in cells of each of the segments labeled with numbers from left to right for the marked rows, starting at the top. Separate each row’s entry from the next with a comma.
