You are viewing with your own eyes the most addictive, brain boggling puzzle ever created. The object of the puzzle is simple...turn the LIGHTS OUT. It seems so easy...at first. The problem is that every press of a button has an effect on the puzzle. Lights that are on will shut off, and "off" lights will turn on. (So, if you touch a button that is lit, it will shut off. Conversely, touching an unlit button will cause it to light up). Moreover, when you touch a button, it not only changes that light, but it also changes the adjacent lights (those that are directly above, below, or next to the pressed button). Your goal is to solve each puzzle in the fewest number of "moves", or steps. The first puzzles are simple, to help you get a feel for the game, and get the basic "logic" of LIGHTS OUT. Later puzzles get progressively more challenging, requiring a little more brain power to solve.
