Find your footing in Nurikabe

Choose a round of Nurikabe and settle into its rules. Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block. Check the relevant rule before repeating a move. Read the objective before making your first input. Choose a clear next step rather than rushing through the instructions.

Play ten compact 5×5 puzzles. Some boards begin with fixed shaded sea cells.

One thing to notice as you play

Before your first action, say what you are trying to achieve. Then compare the result with the goal. Refer to the controls when needed.

The purpose of your moves

Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block. Read that aim before choosing your first action. Start with a deliberate move.

Start here and follow along

  1. Shade sea squares and leave islands white.
  2. Every island contains exactly one clue.
  3. Different islands cannot meet along an edge.
  4. Check puzzle verifies sizes, connectivity and forbidden sea blocks.

Getting comfortable with the controls

Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Read a button’s label before selecting it. Make sure you are interacting with the game rather than the surrounding page.

See how the rules apply

An island labelled 1 is already complete, so its edge neighbours must be sea. Use the example as a guide rather than a substitute for reading your board. Keep the game’s format in mind.

Avoid this misunderstanding

Two numbered islands may not merge into one. Read the feedback to see why an action did not have the expected result. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
