Learn from a sample situation
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. Verify the rule before continuing.
One detail worth checking
Two numbered islands may not merge into one. Check the rule before repeating the action. Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules.
