Next is City, which is pure video-game racing. Players work their way through race after race, meeting challengers of increasing difficulty. They play to earn digital currency called “id Coins”—Hot Wheels stylizes the entire system’s name in lowercase letters—as well as Blueprints, which must be collected to unlock new cars in the game. Players win races by tapping the sides of the screen to steer their car and tapping both sides simultaneously to boost. Although it’s simple, I demo’d a beta version of the app and had a blast. It’s a high-quality mobile game with great graphics and good sound design.
