The traffic is crazy and it's up to you to control it in Traffic Control. Watch the arrows on the roads to see when the cars are coming. Click a car to speed it up. In tough situations, use the slow down power up by clicking the button in the bottom left. There is a re-charge time to be able to use it again. There are 5 levels which can be unlocked by earning 80 points on the previous level or 300 total points for level 2, 600 for 3, 900 for 4 or 1200 for 5. Earn a point for each car that safely makes it through the map, and 2 points for a speeding car. The game ends if there is a collision.
