Blue Divide - Nurikabe

Blue Divide is a peaceful logic puzzle game inspired by the classic Japanese puzzle Nurikabe. Each puzzle begins as a tranquil sea — and hidden within it lie islands of varying sizes, waiting to be revealed.

Use logic to mark which tiles belong to land and which to sea. Each numbered cell tells you how large its island must become, and all the surrounding water must stay connected as one continuous ocean.

• Handcrafted puzzles ranging from gentle to challenging.
• Peaceful visuals and ambient sound that let you relax and focus.
• Logical, no-guess gameplay faithful to the Nurikabe puzzle’s elegant rules.

Blue Divide offers a mindful puzzle experience — perfect for quiet moments or focused breaks.
