Nurikabe: a guide for your next round

Try Nurikabe at your own pace and keep its objective in view. Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block. Keep the game area visible while you use its controls. Choose a comfortable screen position before beginning. Choose a clear next step rather than rushing through the instructions.

Play ten compact 5×5 puzzles. Some boards begin with fixed shaded sea cells.

A small practice goal

Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Refer to the controls when needed.

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. Try to explain the aim in your own words.

Follow these playing steps

  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.

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. Read a button’s label before selecting it. Use one clear input at a time.

Work through an 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. Take a moment to compare.

Keep this in mind

Two numbered islands may not merge into one. Check the rule before repeating the action. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
