A closer look at one example
An island labelled 1 is already complete, so its edge neighbours must be sea. Compare this with the rule that governs the move. Notice the change in the playing area.
A common point of confusion
Two numbered islands may not merge into one. Take a moment to reassess the position before continuing. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
