How to play Nurikabe
Use a short break to learn the rhythm of Nurikabe. Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block. Keep the game area visible while you use its controls. Begin with the solo mode shown on the page. Use the example below to understand a decision.
Play ten compact 5×5 puzzles. Some boards begin with fixed shaded sea cells.
A careful first round
Before your first action, say what you are trying to achieve. Then compare the result with the goal. Keep the objective visible.
Your goal
Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block. Keep that objective in view throughout the round. Start with a deliberate move.
Step by step
- Shade sea squares and leave islands white.
- Every island contains exactly one clue.
- Different islands cannot meet along an edge.
- Check puzzle verifies sizes, connectivity and forbidden sea blocks.
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. A new-round button replaces the current round.
A useful example
An island labelled 1 is already complete, so its edge neighbours must be sea. Apply the same reasoning to the position in your own round. Choose a deliberate next step.
Watch out for this
Two numbered islands may not merge into one. Take a moment to reassess the position before continuing. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
