## What is Nurikabe?

HOW IT WORKS
The board is divided into regions, each with its own color. Shade (tap) squares so that:
- Every region holds exactly two shaded squares.
- Every shaded square touches exactly one other shaded square along an edge. Shaded squares come in pairs, like dominoes, and two dominoes never touch along an edge (corners are fine).
- The size of each region is your only clue. Every puzzle has exactly one solution.

LEARN BY DOING
A short hands-on guided tutorial teaches the rules on tiny boards, one idea at a time, and ends with a puzzle with hints if you get stuck. It runs the first time you open the app, and you can replay it from Settings.

PUZZLES
- Easy pack: ten free 6x6 puzzles
- Medium (7x7), Hard (8x8) and Expert (10x10): ten puzzles each
- Custom: UNLIMITED new puzzles, any size from 5x5 to 10x10, at the difficulty you choose

One purchase unlocks Medium, Hard, Expert and Custom.

BUILT FOR PLAYING
- Tap a square to make it a wall, tap again for an island dot, and a third time to clear it. Drag to paint several squares at once.
