Nurikabe: instructions and practice
Open Nurikabe, check the instructions and begin a round. 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.
Bring this focus to a round
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.
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. Follow this game’s rules rather than another version’s.
Work through the instructions
- 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 use the controls
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. Contact us with the game and device if a control does not respond.
A useful 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. Read the matching step again.
Avoid this misunderstanding
Two numbered islands may not merge into one. Check the rule before repeating the action. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
