We're in the year 2312, and most traffic lights are managed by robots. You're the only remaining human traffic regulator and you really have to do your best to keep your job. You're the one who decides which traffic light will turn green and which light will turn red. Lead the required number of cars out of the traffic chaos. Per level, there's a maximum number of traffic lights that you can make turn green. Each car has a stress meter. The longer a car is stuck in traffic, the more the stress level increases. The traffic control centre will give you a warning when the meter reaches its maximum. Watch out not to receive more than two warnings: at the third warning, you'll be replaced by a robot, too!
