How to play Nurikabe
Make Nurikabe your next activity in the game library. 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.
Try a deliberate move
After a move, check what changed. Decide which rule explains the new state before acting again. Make the next step deliberately.
Your goal
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. Follow this game’s rules rather than another version’s.
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.
Controls
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.
A useful example
An island labelled 1 is already complete, so its edge neighbours must be sea. Apply the same reasoning to the position in your own round. Choose a deliberate next step.
Watch out for this
Two numbered islands may not merge into one. Take a moment to reassess the position before continuing. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
