Nurikabe: a guide for your next round

Take a moment with Nurikabe before moving to another game. Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block. Look at what changes after your first action. Read the objective before making your first input. Keep the game area visible while you use its controls.

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

Practice beyond the first move

Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Make the next step deliberately.

Your objective

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. The example below illustrates a decision.

How a round unfolds

  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. A careful first action helps you become familiar with the layout. Make sure you are interacting with the game rather than the surrounding page.

Follow the 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. Consider the next action carefully.

One detail worth checking

Two numbered islands may not merge into one. A different version of the game may use a different rule. Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round.
