This is a traffic control game where you control the flow of traffic by starting the traffic in a lane by clicking a clock which shows the correct time asked in the question.
There are four sets of clocks; each is connected to a traffic light signal. If you tap a clock showing the asked time, it will make its signal green and rest all will signals will be red. In each level you have to control the traffic for a limited time. Try to solve as many questions as you can, while avoiding the traffic congestion. If you tap the wrong clock, you will lose the level. Game will be tougher gradually as you progress the levels. Try this to see how many points you can get in this game?
