Nurikabe World

Nurikabe World is a 3D logic puzzle game based on the Japanese pen-and-paper puzzle Nurikabe. You place water tiles to form islands around numbered tiles: each number must belong to its own island, which must contain the indicated number of tiles. Islands must be separated by water, all water must connect into one river, and 2×2 water squares, called pools, are not allowed. Completed islands grow trees and other structures.
