The objective of a round

Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block. Keep that objective in view throughout the round. Review the board or playing area as it changes.

From the start of a round

  1. Shade sea squares and leave islands white.
  2. Every island contains exactly one clue.
  3. Different islands cannot meet along an edge.
  4. Check puzzle verifies sizes, connectivity and forbidden sea blocks.

Keyboard and screen controls

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. Use one clear input at a time.

One way to understand the rules

An island labelled 1 is already complete, so its edge neighbours must be sea. Focus on why the action is allowed, not only its outcome. Notice the change in the playing area.

Watch out for this

Two numbered islands may not merge into one. Read the feedback to see why an action did not have the expected result. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
