What you are aiming for
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. Follow this game’s rules rather than another version’s.
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.
Using the playing area
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. A careful first action helps you become familiar with the layout. Look at the feedback after the action.
Follow the example
An island labelled 1 is already complete, so its edge neighbours must be sea. Use the example as a guide rather than a substitute for reading your board. Keep the controls nearby.
A mistake to avoid
Two numbered islands may not merge into one. A different version of the game may use a different rule. After a move, check what changed. Decide which rule explains the new state before acting again.
