Experience the entangled loops, rotate each tile by tapping until perfect harmony is restored. If no loop is open anymore the screen will invert.
Give this lite version a try if you are not sure if you should by the full version of "Loops Of Zen". Here you get one level to play around with. Each time you restart you get a different one, from the three different level engines chosen randomly.
