It is a fun-filled action-packed game that lets you get behind the wheel of a wide range of different cars and drive them onto a variety of different ramps and obstacles. The objective of the game is to drive as far as you can from the starting point to the finish line, while being as careful as you can about the various obstacles that are in your way. The way to achieve this is by gaining enough speed to hit the ramps, and once you do, you will be able to pick up the coins that are lying at the end of each of the ramps.
