Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow. Make the next step deliberately.

The steps to play

- Every island contains exactly one clue.
- Different islands cannot meet along an edge.
- Check puzzle verifies sizes, connectivity and forbidden sea blocks.
Keyboard and screen controls
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. Make sure you are interacting with the game rather than the surrounding page.
Try this 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. Read the matching step again.
One detail worth checking
Two numbered islands may not merge into one. Take a moment to reassess the position before continuing. After a move, check what changed. Decide which rule explains the new state before acting again.
