Nurikabe: instructions and practice
Start Nurikabe by looking at the playing area and its controls. Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block. Choose a clear next step rather than rushing through the instructions. 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
Read one step at a time and try it on the playing area. Match the instruction to the control you use. Notice the feedback after each input.
Understand the aim
Create one connected sea around numbered islands of exactly the stated size, without a 2×2 sea block. An attractive position is not enough unless the goal is met. Review the board or playing area as it changes.
A walkthrough of the rules
- Shade sea squares and leave islands white.
- Every island contains exactly one clue.
- Different islands cannot meet along an edge.
- Check puzzle verifies sizes, connectivity and forbidden sea blocks.
How to interact with the game
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. Make sure you are interacting with the game rather than the surrounding page.
An example to follow
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. Keep the controls nearby.
A common point of confusion
Two numbered islands may not merge into one. A different version of the game may use a different rule. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
