Your goal
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. Notice how the game responds to your input.
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.
Controls
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Read a button’s label before selecting it. Return to the rules if the result is unexpected.
A useful example
An island labelled 1 is already complete, so its edge neighbours must be sea. Focus on why the action is allowed, not only its outcome. Read the matching step again.
Watch out for this
Two numbered islands may not merge into one. A different version of the game may use a different rule. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
