In Light Up, you'll coincidently use lights to brighten up every available white square. Think of it as an advanced version of Minesweeper, as you'll have to decide where to place the cross-lighting bulbs based off of a proximity hinted at by the numbers.
Similar to Light Up is Nurikabe. Loosely translated, the title references invisible walls that block roads in Japanese folklore. Hence the asphalt tiles that you'll try to build into islands around still more numbers.
