After a move, check what changed. Decide which rule explains the new state before acting again. Make the next step deliberately.
The objective of a round

A walkthrough of the rules

- Check puzzle verifies sizes, connectivity and forbidden sea blocks.
Making selections and moves
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. Make sure you are interacting with the game rather than the surrounding page.
A closer look at one example
An island labelled 1 is already complete, so its edge neighbours must be sea. Apply the same reasoning to the position in your own round. Look for the relevant detail.
Avoid this misunderstanding
Two numbered islands may not merge into one. Read the feedback to see why an action did not have the expected result. When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round.
