The cars in Road Crash are all insane! Because in this race, you're gonna have to crash your car into others to get them off of the road and be the first one to cross the finish line! To play all you need is your arrow keys and your mouse. Simply, use your mouse to open new boxes and drag the same numbered cars on top of each other. When you merge them, you create a new and improved one! Then, enter the race and collect coins to unlock new cars. Have fun!
