The objective of a round
Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block. Use the instructions to see which actions move you towards it. Follow this game’s rules rather than another version’s.
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.
Input guidance
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. Check any mode label before starting.
Follow the example
An island labelled 1 is already complete, so its edge neighbours must be sea. Apply the same reasoning to the position in your own round. Check the stated objective.
Where a round can go wrong
Two numbered islands may not merge into one. Read the feedback to see why an action did not have the expected result. Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules.
