Lux is a chain reaction game. When you click on a pattern of light, it expands, and any other pattern of light in that range also expands, continuing in a chain reaction. You receive more points for longer chains. There are also lights which expand on their own and give you negative points unless you click them quickly, and there are special lights which give you extra points. There's also an online high score table. The game doesn't have very much depth, but it's pretty relaxing.
