Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow. Use the example to check your reasoning.

- Different islands cannot meet along an edge.

Choosing and moving on screen
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Read a button’s label before selecting it. A new-round button replaces the current round.
Try this 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. Choose a deliberate next step.
Notice this detail
Two numbered islands may not merge into one. A different version of the game may use a different rule. Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round.
