Anything goes when you're in the ring, so get crashing and smashing.Click the types of music you want to listen to and click “BLAST RADIO,” or simply click “NO RADIO.” Build up some speed to deal some serious damage when you smash into the other cars! An enemy's health meter is shown on the trunk of his car. Your health points are shown next to each side of your card in the top-right corner. Be the last car standing in the ring to complete a level!
