You are in :Sports Monkey Games
Just like in a real life where these carts differ in power and size, here too we have 4 different machines: green gecko (that one you get for free), blue hawk (the name sound much better right?), tiger tank (I would like to drive that one myself) and 'whale shark' reserved for pros only.
How to play?
Use arrow keys to control your kart, to go left and right, step on a gas pedal or to brake. This kart can do something extra compared to real-life karts. If you press space bar you will jump, and on top of that if you press 'x' you will do some air-stunts.
