Theme: Clue Symmetry & Logic
Author/Opus: This is the 4th puzzle from guest contributor Jamie Hargrove.
Rules: Variation of Nurikabe. Some of the given island clues are actually part of the ocean and must be shaded over. (All other Nurikabe rules still apply, including all islands contain exactly one clue number equal to the area of the island.)
Answer String: Enter the length in cells of each of the black segments (the unnumbered, connected “ocean”) from left to right for the marked rows. Enter both digits for any two-digit number. Separate each row’s entry from the next with a comma.
Time Standards (highlight to view): Grandmaster = 3:30, Master = 8:15, Expert = 16:30
