The essentials of playing Nurikabe
Choose a round of Nurikabe and settle into its rules. Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block. Keep the game area visible while you use its controls. Choose a comfortable screen position before beginning. Use the example below to understand a decision.
Play ten compact 5×5 puzzles. Some boards begin with fixed shaded sea cells.
Give this approach a try
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Use the example to check your reasoning.
The purpose of your moves
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. Check the rules when you are unsure.
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.
How your actions work
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. Use one clear input at a time.
Follow the 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. Take a moment to reassess the position before continuing. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
