If the game freezes, just click inside it (games can get unresponsive if you click elsewhere on the page).
See if you can take this monster truck for a 18-level ride on a test polygon. Drive over obstacles and cars, try to reach the end of track.
You need to drive slowly over some, and try to jump over other obstacles. But beware of the borders, as you will have to restart if you touch any.
Enjoy 3D graphics, test your driving and parking skills and have fun.
