Understand the basics of Nurikabe

Read the aim of Nurikabe, then make your first move. Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block. Check the relevant rule before repeating a move. Compare the starting position with the example in the Guide. 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.

Take a closer look while playing

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

Understand the aim

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.

Work through the instructions

  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.

Making selections and moves

Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Use the control method described here for this activity. Contact us with the game and device if a control does not respond.

Follow the 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. Take a moment to reassess the position before continuing. After a move, check what changed. Decide which rule explains the new state before acting again.
