What you are aiming for

Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block. The feedback beside the game helps you follow the round. Check the rules when you are unsure.

The steps to play

  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.

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. A careful first action helps you become familiar with the layout. Use the visible help when you are unsure of the next input.

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. Read the matching step again.

Notice this detail

Two numbered islands may not merge into one. A different version of the game may use a different rule. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
