The game plays like most racers, and as you play through the multinational levels, you gain money for winning and use it to buy more cars and tweak their performance. There’s also a leveling system, which controls which cars you can buy. There are more than 30 cars and motorbikes to unlock, each with their own play style and stats. As you level up, you also unlock girls, who give you a boost in one way or another. Though it would have been nice to see a guy thrown in there too, just to even things out.
The controls are absolutely perfect for the iPhone in their default mode. You steer with tilt, and the only buttons you have to worry about are boost and brake. The steering is very touchy, so it is easy to oversteer, and go pinballing between sides of the course. Not exactly true to life, but more fun that way. You earn more cash through crazy stunts too, in a similar way to the Burnout games. So driving people off the road, narrowly avoiding traffic, smashing street signs all earn you money. However, totaling your car costs you a lot, both in race time and money, so avoid incoming traffic.
