Nurikabe Islands in the Stream

Some grids have incorrect solutions, requiring a water cell where there should be a land cell. This leaves a 2x2 square of water and an island one cell short. The buggy grids occur intermittently, not every game.

It randomly generates a Nurikabe, as advertised. Pros: -100% free. There’s ads, but they’re not intrusive. They only appear when you beat a puzzle. They’re short ads, too. -No hints but will show you the solution if you get stuck. Cons: -You can’t choose the difficulty. I’ve done 6 so far and all are pretty easy for experienced players. Difficulty seems to be increasing. Could be wishful thinking or due to an algorithm. -It pauses Spotify and iTunes music at the end of each puzzle and during ads.
