LIGHTS_OUT Simulate the "Lights Out" Puzzle

LIGHTS_OUT, a MATLAB program which sets up the "Lights Out" game and allows a user to try to solve it.

The Lights Out game is played on a rectangular board of squares, usually a 5x5 grid, each square containingr a light that may be on or off. Clicking the mouse on a light switches it from on to off and vice versa. However, when you switch a light, you also switch the lights to the immediate left, right, above and below.

You start the game with a randomly chosen configuration of lights and it's up to you to figure out how to get them all out.

Languages:

LIGHTS_OUT is available in a C version and a C++ version and a MATLAB version.
