Nurikabe

Flood the sea around islands whose numbers give their size

Rules

Shade squares as sea so that every white island holds exactly one number and has that many squares. All the sea is one connected body, and it never fills a 2×2 square. Tap to shade sea, long press to switch to dots — a dot only marks a square you have decided is island.
