Lights Out

The game is simple, just turn the lights off! Click the 3x3-On/Off or 5x5-On/Off buttons to start a new game of the given size. Then click on the light buttons until all the lights are off (note black is off and green is on). For an added challenge, you can add a dimmer switch! That is, you'll have three colors to rotate between going black-green-red-black.
