Easy Nurikabe — what to expect
Easy Nurikabe uses 5×5 grids with small islands (typically 1 to 4 cells). Island isolation handles the cells numbered 1 — just surround them with sea. For the rest, look for cells that no island can reach. At this size the sea connectivity constraint rarely causes trouble because there simply isn't room for the sea to split.
