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. On a smaller screen, keep the active part of the board within view. Look at the feedback after the action.
A closer look at one 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. Consider the next action carefully.
Where a round can go wrong
Two numbered islands may not merge into one. A different version of the game may use a different rule. 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.
