Author/Opus: This is the 176th puzzle from our contributing puzzlemaster Prasanna Seshadri.
Rules: Variation of Yajilin. Blacken some white cells and then draw a single closed loop (without intersections or crossings) through all remaining white cells. Blackened cells cannot share an edge with each other. A number in a region indicates how many white cells must be blackened. Cells with number clues may be blackened.
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 = 3:15, Master = 4:30, Expert = 9:00
