Nurikabe: how a round works
Nurikabe gives you a focused activity to play in your browser. Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block. Choose a clear next step rather than rushing through the instructions. Compare the starting position with the example in the Guide. Keep the game area visible while you use its controls.
Play ten compact 5×5 puzzles. Some boards begin with fixed shaded sea cells.
A focus for your next round
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. Use the instructions to see which actions move you towards it. Keep the controls in easy reach.
How to proceed
- 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 to interact with the game
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. Look at the feedback after the action.
Follow the example
An island labelled 1 is already complete, so its edge neighbours must be sea. Focus on why the action is allowed, not only its outcome. Check the stated objective.
Pay attention to this rule
Two numbered islands may not merge into one. Take a moment to reassess the position before continuing. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
