Follow the steps for 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. Choose a clear next step rather than rushing through the instructions. Check the rule that explains your first action. Look at what changes after your first action.
Play ten compact 5×5 puzzles. Some boards begin with fixed shaded sea cells.
One thing to notice as you play
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. Keep the objective visible.
Your goal
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. Notice how the game responds to your input.
From the start of a round
- 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. On a smaller screen, keep the active part of the board within view. Use one clear input at a time.
An example before you play
An island labelled 1 is already complete, so its edge neighbours must be sea. Your next round may have a different position, so inspect it before acting. Take a moment to compare.
Watch out for this
Two numbered islands may not merge into one. Read the feedback to see why an action did not have the expected result. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
