The difficulty levels are the same as in the racing mode. This mode can be a lot more interesting because you must do stunts and race at the same time. Second is the choice of a Single Event. These include race, freestyle, and combo. These are great when first learning the game.
Single race is against the computer.
It is a good way to get to know the tracks, and learn the controls. Freestyle is of course where you acquire your stunt skills. Combo is my favorite. In this mode racing and stunts are combined to get the final score. Next are the Time Trials.
