Nurikabe: a guide for your next round
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. Use the opening round to become familiar with the layout. Keep the game area visible while you use its controls.
Play ten compact 5×5 puzzles. Some boards begin with fixed shaded sea cells.

What the game asks you to do
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. Keep the controls in easy reach.
Start here and follow along
- 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.
Choosing and moving on screen
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. Use the visible help when you are unsure of the next input.
Put the rules into context
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. Keep the controls nearby.
A useful caution
Two numbered islands may not merge into one. A different version of the game may use a different rule. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
