A practical guide to Nurikabe

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. Check the relevant rule before repeating a move. Read the objective before making your first input. Use the example below to understand a decision.

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

Practice beyond the first move

Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart. Keep the objective visible.

Your goal

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. Return to the instructions when a step is unclear.

How to proceed

  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.

How to use the controls

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. Your next round may have a different position, so inspect it before acting. Consider the next action carefully.

A common point of confusion

Two numbered islands may not merge into one. Read the feedback to see why an action did not have the expected result. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
