Nurikabe: rules and examples
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. Read the objective before making your first input. Use the example below to understand a decision.
Play ten compact 5×5 puzzles. Some boards begin with fixed shaded sea cells.
A focus for your next round
Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules. 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. Return to the instructions when a step is unclear.
Making your moves
- 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. On a smaller screen, keep the active part of the board within view. Contact us with the game and device if a control does not respond.
Work through an 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. Notice the change in the playing area.
Watch out for this
Two numbered islands may not merge into one. A different version of the game may use a different rule. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
