The object of the game is to get the highest score. This is normally done by driving as long as possible without bombing out while collecting all the coins you can. But you can also try to perform stunts and special moves while in the air. This is how you can really score more points.
As you play, you can keep upgrading your vehicle's performance with all the money you've earned along the way. By doing so, you get to have a real road beast that you can test out in five different settings. The Arctic, the field, the desert, and the Moon are just some that are included.
Hill Climb Racing is a very entertaining game, reminiscent in some respects of the superb Extreme Road Trip. Perfect controls and addictive game mechanics amply justify the more than ten million downloads this game has already accumulated.
