Anywhere, you go you can expect heavy traffic. And in the city, the traffic is much worse compared to a town since there are more vehicles. What is even worse is that most of the drives seems to be hot headed and they won't give way.
The game is played via mouse you control the traffic by clicking on the vehicles. You can make it go fast, stop and go on if you click on it. The idea here is to make sure that there won't be any accident. The game will be harder and harder as you make some progress.
