If you have ever scribbled all over a paint app and then used the fill tool to gradually make the screen a single color, this is the app for you.
PixelFlood is a simple game, with an elegant design. You can try changing colors as fast as you can to beat the clock, or thoughtfully consider each move to clear the screen as efficiently as possible.
Colors can come from any side. Just rotate your screen until you see the highlight move to the side you like. Use this for a strategic advantage, or just play upside down if you prefer.
