Press Start to reset the game. The 6 buttons on the Control Panel change which traffic lights are Green and which are Red. To win, you must find the pattern where traffic flows in one direction with cross traffic stopped and alternate which streets in the intersection have green lights. Your win is confirmed when this is accomplished 2 times in a row.

Strategy This is a puzzle. The point is to figure out how buttons on the Panel change the lights and deduce a sequence to obtain stopped cross traffic and then alternate which street is Green and which is Red. This is a simple enough version, that you could randomly push buttons and find the solution. Added intersections or more complex ones (left turn lanes?) will increase the difficulty exponentially.
