The rule is very simple, we have a high speed racing between 2 Cars on 2 lanes simultaneously. And you have to control 2 cars at the same time. ( We design cars on model of Ford Mustang, or Ferrari whatever ). On the high way, the 2 cars have to avoid square blocks and catch the circle one. You must you 2 fingers to tap on screen to change their lane. Racing speed of two cars will raise up when you get higher score.
