Gridlock Buster challenges you to manage the flow of traffic in a gridlocked city in the not-too-distant future. Click on an intersection to change the traffic light to keep the traffic flowing. If cars have to wait for too long, they get frustrated. You fail if the frustration meter fills up. Earn more points by having cars wait for as little as possible. On later levels you will be able to program the signal timing to set up a perfect pattern for optimal traffic flow.
