Nurikabe World

Here's an excerpt from Nurkabe World's Steam description:

Nurikabe World is a relaxing logic puzzle game where you solve puzzles by creating islands and connecting rivers to create beautiful sceneries. Nurikabe World reimagines the classic Japanese pen-and-paper puzzle Nurikabe as a 3D game, where islands spring to life with trees and structures. Either play handcrafted puzzles, immerse yourself in the flow of infinitely generated maps or create and share your own puzzles with the integrated level editor.

In Nurikabe World, you create islands by placing water tiles. Each number must be separated into its own island with the indicated number of tiles. Completed islands will grow trees and other structures.

Getting started is easy, you only need to know a few rules to start playing!

• All islands must be separated by water
• The water must form one connected river
• 2x2 water squares, called "pools", are not allowed

Nurikabe World has puzzles of all sizes and difficulty levels. The crafted puzzles will take you through breezy 5x5 levels to 15x15 endurance-testing experiences and more. There are also a bunch of difficult smaller puzzles for bite-sized challenges.

Solving harder puzzles will require you to learn advanced solving techniques, which you'll learn along the way.
