The Nurikabe playbook
Take a moment with Nurikabe before moving to another game. Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block. Look at what changes after your first action. 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.

What you are aiming for
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. Try to explain the aim in your own words.
How a round unfolds
- 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. Keep the playing area visible while using these controls. Return to the rules if the result is unexpected.
Try this example
An island labelled 1 is already complete, so its edge neighbours must be sea. Your next round may have a different position, so inspect it before acting. Keep the controls nearby.
A useful caution
Two numbered islands may not merge into one. A different version of the game may use a different rule. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
