Speed Racing is a competitive game of paper dolls

Speed Racing is a car racing game developed by John Hwang’s TripMonger (now part of Zynga) that has all of the tell-tale signs of a viral game. The game’s economy is based purely on driving new sign-ups for the game – in order to obtain parts to win races, you need to gain points; the only way to gain points is to invite friends and have them join. Like many of the viral games out there, the only way to succeed is to help perpetuate the game.
