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.

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.

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.

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

Customer Reviews

Great way to pass the time!

A friend recommended this to me, and I couldn't stop playing! You get so much with the free version. I also love that there are weekly bonus puzzles, so I never have to spend a dime! I might, eventually, though, since the puzzles are so fun.


This game gets under your skin. I was spending so much time on it, I decided to delete it from my phone. After two weeks I missed it so much I had to put it back. Only app ever that has achieved that status with me.


I discovered Nurikabe in the New York Times and I have loved it ever since. This app is amazing! Extremely user friendly. It also outlines the many techniques necessary to solve the hardest puzzles. This app basically sets the standard for all Nurikabe apps.
