Find your footing in Nurikabe
Start Nurikabe by looking at the playing area and its controls. 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. Keep the instructions close while learning this activity. 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.
A small practice goal
When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round. 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. The feedback beside the game helps you follow 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.
How to use the 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. Use the visible help when you are unsure of the next input.
An example to follow
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. Verify the rule before continuing.
A useful caution
Two numbered islands may not merge into one. Check the rule before repeating the action. 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.
