Nurikabe: rules and examples
Read the aim of Nurikabe, then make your first move. 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.
Build familiarity through play
Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round. Keep the objective visible.
Your objective
Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block. The feedback beside the game helps you follow the round. Take a moment to understand the current position.
A walkthrough of the rules
- 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.
Making selections and moves
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. Avoid pressing the same control repeatedly while a move is being processed.
An example to follow
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.
Where a round can go wrong
Two numbered islands may not merge into one. Read the feedback to see why an action did not have the expected result. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
