What counts as success
Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block. Read that aim before choosing your first action. Review the board or playing area as it changes.
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.
Your inputs
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Keep the playing area visible while using these controls. Contact us with the game and device if a control does not respond.
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. Look for the relevant detail.
Keep this in mind
Two numbered islands may not merge into one. Check the rule before repeating the action. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
