One way to understand the rules
An island labelled 1 is already complete, so its edge neighbours must be sea. Your next round may have a different position, so inspect it before acting. Keep the game’s format in mind.
One detail worth checking
Two numbered islands may not merge into one. Read the feedback to see why an action did not have the expected result. After a move, check what changed. Decide which rule explains the new state before acting again.
