Islands (aka Nurikabe)
Paint some cells black (the sea) leaving some cells white (the islands).
Each given number is part of an island. Each island contains exactly one number, which is the number of squares forming that island. Two different islands cannot connect by an edge, but they may touch at a point.
The black squares form a single group of cells connected by edges. There cannot be a 2x2 region which is entirely black.
Croco keyboard shortcuts: Q or # paints black, W or - paints white.
There's been a Preisratsel already for this type, so I'd recommend trying that first before doing the U-Ratsel.
