Nurikabe Number Wall Puzzle

Nurikabe Number Wall Puzzle is a clean Japanese logic puzzle based on the classic Nurikabe rules, also known as Islands & Walls, Number Wall, Island Puzzle, and Islands in the Stream.

Read the number clues, separate the grid into white number islands, and paint the remaining cells into one connected black sea or wall. Each number belongs to one island, and the island must contain exactly that many cells. Islands cannot touch each other horizontally or vertically. The black sea must stay connected, and no 2x2 block of black cells is allowed.
