See how the rules apply
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. Check the stated objective.
Watch out for this
Two numbered islands may not merge into one. A different version of the game may use a different rule. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
