The essentials of playing Nurikabe
Take a moment with Nurikabe before moving to another game. Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block. Use the example below to understand a decision. Begin with the solo mode shown on the page. Keep the game area visible while you use its controls.
Play ten compact 5×5 puzzles. Some boards begin with fixed shaded sea cells.
Give this approach a try
Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round. Make the next step deliberately.
What you are aiming for
Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block. Keep that objective in view throughout the round. Review the board or playing area as it changes.
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.
Your inputs
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. A careful first action helps you become familiar with the layout. Use the visible help when you are unsure of the next input.
Learn from a sample situation
An island labelled 1 is already complete, so its edge neighbours must be sea. Compare this with the rule that governs the move. Check the stated objective.
Check this before moving on
Two numbered islands may not merge into one. Compare the situation with the worked example. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
