Nurikabe: how a round works
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. Keep the game area visible while you use its controls.
Play ten compact 5×5 puzzles. Some boards begin with fixed shaded sea cells.
Try a more deliberate round
After a move, check what changed. Decide which rule explains the new state before acting again. Notice the feedback after each input.
Your goal
Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block. An attractive position is not enough unless the goal is met. Review the board or playing area as it changes.
How to proceed
- 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.
The controls to know
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Read a button’s label before selecting it. Use the visible help when you are unsure of the next input.
Try this 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. Notice the change in the playing area.
A useful caution
Two numbered islands may not merge into one. Read the feedback to see why an action did not have the expected result. When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round.
