Theme: Clue Symmetry and Logic (for patron Chris Green)

Author/Opus: This is the 126th puzzle from our contributing puzzlemaster Prasanna Seshadri.

Rules: Standard Masyu rules. Also, the loop must make the same number of turns in each bold region that it enters. It is up to you to determine how many turns this is. Be sure to count all turns, including turns in black circles. (The loop does not necessarily enter all regions.)

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 = 6:30, Master = 8:30, Expert = 17:00

Solution: PDF; a solution video is available here.
