This is the best racing game for free. The most distinctive feature of this game is that you can not only run freely but also compete with other players. It is not monotonous to play this game because there are different maps for you to try. 

Altogether, you will have ten maps. Besides, at the beginning of this game, you can also design your own character, skin and clothes etc. But in different maps, you will need different skills to move to unlock the next map. At the upper left side of the map, you will see the ranking list, so what you need to do is to defeat other players and improve your own rank. 

Of course, it is also very important for you to collect all the gold coins because you can use them to buy new clothes and your favourite skin color. You might think it does not matter what kind of skin color you have, but sometimes if you change the skin color of your character, the whole game will give you a totally different feeling.
