Oh, this is an irritating little game. It looks like a hand held game, and when you hit new game, it turns some of the lights on. Where ever you click, including on the dark squares, which I did by accident, changes the light pattern. The object is to get all the lights off. Good luck! Just when you think you got it in one or two moves, a whole bunch of lights come on. At this time, I have still to get all the lights off.
