Kart racing is a real racing simulator based on professional physics engine.
Karts are small but very fast racing cars popular all over the world. Most of Nascar, Formula 1, Indy car, Rally drivers started their careers from karting.
If you feel the need for speed and want to experience good racing simulation on your phone, you definitely should try this game. Unlike drag racing your results highly depend on you ability to pass corners and brake efficiently.
- Start your career and go through three leagues starting from 15 hp kart and get 90 hp superkart in the end.
- Earn money in races and buy new car parts that increase cars performance.
- Unlock new tracks.
