With over 50 million users on Google Play alone, Traffic Racer proves that road rage translates quite well into digital form. The free app from developer Soner Kara challenges players to race through the streets at top speed while darting between traffic. Points are awarded for hitting high speeds, travelling longer distances, riding against opposing traffic and cutting it close while overtaking other vehicles. The gameplay is easy to learn but difficult to master. Use on-screen buttons or tilt the screen to navigate the roads, while acceleration can be managed either manually or automatically. You are given a basic pickup truck as your starter vehicle with limited modifications until you earn money for upgrades.
