Nurikabe puzzles were originally introduced by Nikoli in Japan during 1991. The rules for this island-forming puzzle are quite simple: Each puzzle consists of a grid containing clues in various places. The object is to create islands by partitioning between clues with walls so that the number of squares in each island is equal to the value of the clue, all walls form a continuous path and there are no wall areas of 2x2 or larger. Each island must contain one clue and be isolated from other islands horizontally and vertically.
