Nurikabe: from controls to your first round
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. Keep the game area visible while you use its controls. Read the objective before making your first input. 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.

Your inputs
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.
Learn from a sample situation
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.
Watch out for this
Two numbered islands may not merge into one. Take a moment to reassess the position before continuing. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
