Nurikabe is great logic game that is fun for all ages. 21000 grids ranging from small 5x5 up to large 10x10, including rectangular grids. The goal is simple; fill the grid with rivers or islands following the game rules. Rule 1. The river should be a single continuous flow. Rule 2. Each island must contain one number and consist of that number of squares (counting the square with the number). Rule 3. The river cannot consist of a 2x2 block of water (lake). Smaller grids are great for younger players or if you just want a quick game. Larger grids will provide a challenge to even the best puzzle solvers. Grids can be zoomed in and out using a spread and pinch motion to easily complete large grids even on smaller devices. ## Key features - Logic puzzle gameplay - 21000 unique grids - Adjustable grid sizes (5x5 to 10x10) - Zoom in/out functionality - Island and river filling mechanics - Suitable for all ages ## Recent user reviews (2 of 2) All indexed reviews: https://appshunter.io/ios/app/nurikabe-vla/id1564596038/reviews.md ### 1/5 — Does not work *2024-02-03* Does nothing when you hit play 😔 ### 4/5 — Excellent app, a few quirks *2022-01-03, version 1.0* Provides an effectively infinite number of puzzles of a variety of sizes. Controls are good. Ads are present but unintrusive. Two issues, however. One is that some puzzles are not solvable; specifically 8x10 #111. I’ve double and triple checked this; the puzzle itself is self-contradictory. The other is that the “pencil” control doesn’t work - the X clears out only “dotted” squats, now solid ones. So using it to roll back after invalidating a guess is useless as a result. ## Frequently asked questions about Nurikabe vla ### What are the rules of Nurikabe?
