Traffic master turns you into a traffic controller of major cities like New York, Springfield, Miami.This game basically gets you on a crossing where lot of cars, trucks etc pass on. You need to make every pass through safely without accidents by either stooping them or accelerating them. This game is free for next two days so make sure you grab it. Works on iPad / iPad 2 / iPhone / iPod.
