An introduction to playing 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. 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.

Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart. Keep the objective visible.
What you need to achieve
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. Return to the instructions when a step is unclear.
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.
Using the playing area
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. Read the example below alongside these instructions.
A closer look at one example
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. Verify the rule before continuing.
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.
