What the game asks you to do

Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block. Read that aim before choosing your first action. Take a moment to understand the current position.

Start here and follow along

  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. A new-round button replaces the current round.

Try this example

An island labelled 1 is already complete, so its edge neighbours must be sea. Your next round may have a different position, so inspect it before acting. Read the matching step again.

A mistake to avoid

Two numbered islands may not merge into one. Read the feedback to see why an action did not have the expected result. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
