## What is Nurikabe?

Nurikabe is a logic puzzle about splitting a grid into islands and sea. Each number marks an island made of exactly that many cells. Islands never touch, all the water joins into one connected sea, and no 2x2 block of sea is allowed. Every puzzle has one solution and can be solved by logic alone, so there's never any guessing.

Features:
• One-tap controls: tap a cell to flood it with sea, tap again to mark land, tap a third time to clear
• Numbered clues tell you exactly how big each island must be
• Smart highlighting flags water that breaks the rules
• Cells lock in as the grid resolves toward its solution
• Three sizes to grow into: 6x6 Easy, 8x8 Medium, 10x10 Hard
• Undo any move with a single tap
• Progress saves automatically, so you can stop and pick up later
• Stats and best times for every difficulty
• Plays fully offline

Quiet, clever, and deeply satisfying. If you like Sudoku, Nonograms, or Hashi, Nurikabe could be your next obsession.
