Your objective is to finish each race in the first place to earn the most points and coins. There are 4 races each with a different difficulty that you can complete. When in a race, your car will move on its own but you should use the left and the right arrow keys to avoid crashing into others. You'll see speed boosters on the road. Drive over these yellow arrows to increase your speed. After you reach the finish line, you have a chance to collect coins. Grab as many of them as you can, as these can be used to upgrade your 4 different stats.
