Rules: Standard Nurikabe rules. Also, the numbers outside the grid show the number of shaded segments visible in that direction (as in Skyscrapers). A shaded segment of length N in a given direction is taken as a building of height N. A building blocks the view of any building behind it of equal or lesser height. For instance, in the example, there are 3 buildings seen in the fourth row from the left (as 1 < 2 < 3) but only 1 building seen in the third row from the right (as 3 > 2).
