Theme: Clue Symmetry and Logic.
Author/Opus: This is the 2nd puzzle from guest contributor Tapio Saarinen (including an earlier Sunday Surprise co-authored with Thomas Snyder).
Rules: In this variation of Nurikabe, the islands are now given outside the grid. These numbers must be placed in the first white island cell encountered in the corresponding direction. Each number represents a distinct island, with a total of 10 islands in this puzzle.
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, starting at the top. Separate each row’s entry from the next with a comma.
Time Standards (highlight to view): Grandmaster = 5:45, Master = 8:30, Expert = 17:00
