The objective of a round
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. Start with a deliberate move.
The playing sequence
- 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. Use the control method described here for this activity. Check any mode label before starting.
Try this example
An island labelled 1 is already complete, so its edge neighbours must be sea. Compare this with the rule that governs the move. Check the stated objective.
An important reminder
Two numbered islands may not merge into one. Check the rule before repeating the action. 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.
