Nurikabe: what to know before playing

Choose a clear next step rather than rushing through the instructions. Use the opening round to become familiar with the layout. Keep the game area visible while you use its controls.
Play ten compact 5×5 puzzles. Some boards begin with fixed shaded sea cells.

Work through an example
