The rules of the game are pretty easy. Bars appear on the screen. Each of them is placed at random and overlaps the ones that are below it. The goal of the game is to remove the bars one by one by tapping onto them. Beware though that you can only remove the bar, which is on the very top ? if it overlaps with another bar, it will never disappear. Periodically new bars will appear on the screen. Therefore you have to be quite fast in making up your mind which bars to remove.
