Author/Opus: This is the 6th puzzle from guest contributor Freddie Hand.
Rules: Standard Masyu rules, but any two consecutive line segments cannot have the same length (i.e., on both sides of any turn, the loop must travel different lengths).
Answer String: Enter the length in cells of the horizontal loop segments from left to right in the marked rows, starting at the top. If the loop only has vertical segments in the marked row, enter 0. Separate each row’s entry with a comma.
Time Standards (highlight to view): Grandmaster = 3:30, Master = 4:30, Expert = 9:00
