App Description

Partition between clues with walls to create islands with corresponding size! 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.

Nurikabe are addictive island-forming puzzles which were invented in Japan. Using pure logic and requiring no math to solve, these fascinating puzzles offer endless fun and intellectual entertainment to puzzle fans of all skills and ages.

The game features a highlighting option to help see if a wall segment is about to become isolated, and an island size counter to view how many squares belong to an island.

To help see the puzzle progress, graphic previews in the puzzle list show the progress of all puzzles in a volume as they are being solved. A Gallery view option provides these previews in a larger format.

For more fun, Conceptis Nurikabe includes a Weekly Bonus section providing an extra free puzzle each week.
