Object: Make all Traffic Lights show the green light. 
 
Click anywhere on the board to allow Zillions to create a random setup.
 
Each Traffic Light will go from green to orange to red when you click it. However, each Traffic Light will also advance certain other Traffic Lights. It may affect every second or every third or every fourth Traffic Light or..., counting clockwise and starting at the clicked Traffic Light. You have to find this out for yourself.
 
How a certain Traffic Light affects the other Traffic Lights changes from game to game.
 
A simplified version of this game is 'Hearts'.
