Those who played the original DrawRace game know this isn't your traditional racing game where you steer a vehicle around a course. Rather this is a line-drawing game where you draw a path for your car to follow around the track for a couple of laps. That line you draw--as well as the speed with which you drew it--is recorded. You then sit back and watch your car take the path you've drawn and see how well it fares against other cars in the race (you can press the turbo button to give your car a little boost, but that's the extent of the in-game controls).
Along with a career mode that unlocks various tracks and cars, you can race against other players locally (on your device against friends) or online with players from around the world.
DrawRace 2 has much-improved 3D graphics and the game, while simple to play on the surface, is challenging and addicting. It's also available for the iPhone, but sadly this isn't a universal app.
