Here is an overview of the game, via Microids:

It’s time to heat up your engines! Choose your Smurf—each one having their own kart and unique ability—and take part in wild races!

Start off strong, find shortcuts, use the right items at the right time to pass your opponents and become the village’s best kart driver!

Play solo or with friends and family, should you be a beginner or the most trained driver… get the pole position and show others who is the fastest Smurf of all time!
