You'll take advantage of the minimap located in the lower left corner of the screen, where you'll see where the garages, races and the police are, yes, the police, because you'll take part in illegal races and they'll try to catch you, if you evade them you'll earn money and points too.
In the garages you'll be able to paint, tune and upgrade your car, buying new engines, transmissions or wheels that will help you in the races.
If the police is following you, you'll be able to evade them driving faster than them or changing the color of your car in one of the garages in the city.
The graphics of the game are really good as you can check looking at the screenshots, the sound is good too, although the speed sensations are not as good as we'd like them to be.
It's totally free and it's not difficult to use, what makes City Racing an interesting choice if you want to have fun for free driving cars and pushing the pedal to the metal.
