What the game asks you to do
Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block. An attractive position is not enough unless the goal is met. Follow this game’s rules rather than another version’s.
How a round unfolds
- 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.
Getting comfortable with 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. Read a button’s label before selecting it. Avoid pressing the same control repeatedly while a move is being processed.
Put the rules into context
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. Keep the game’s format in mind.
Watch out for this
Two numbered islands may not merge into one. Take a moment to reassess the position before continuing. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
