Rules, controls and help for Nurikabe
Try Nurikabe at your own pace and keep its objective in view. Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block.

Practice with a purpose
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Keep the objective visible.
What counts as success
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. Review the board or playing area as it changes.
From the start of a round
- 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.
How your actions work
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Use the control method described here for this activity. Make sure you are interacting with the game rather than the surrounding page.
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. Take a moment to compare.
A useful caution
Two numbered islands may not merge into one. Check the rule before repeating the action. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
