- Different islands cannot meet along an edge.

Using the playing area
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. A new-round button replaces the current round.
One way to understand the rules
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. Keep the controls nearby.
Notice this detail
Two numbered islands may not merge into one. Read the feedback to see why an action did not have the expected result. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
