Lights Out is a logic Puzzle Game created by Tiger Electronics in 1995. The game consists of a 5x5 grid of Lights, each of which can be either on or off. The Goal is to Turn all the Lights off by pressing the buttons that Control them.
To play, press any of the buttons on the grid. When you do, the button you pressed and the four adjacent buttons (above, below, left, and right) will toggle from on to off or vice versa. Your Goal is to Turn off all the Lights.
The game can be made more DIFFicult by increasing the size of the grid or by introducing more complex rules.
