As some of you know, I have an affinity for programming the 'Lights Out' game.  For those who don't remember it, here's a summary:  You are presented with a grid, say 4x4, of squares, some white, some black.  The objective is to turn them all black in the shortest number of moves.  When you click on a square, that square and squares horizontally and vertically adjacent to that square turn to the opposite color.

It's an old game.  I remember playing with it when I was in elementary school.  It was in the AG (academically gifted) class.  The game was a part of another game.  We, students as a group, got about five tries to turn all lights out.  After that, we had to solve a few math problems before getting five more tries.  The memory takes me back, but making the game does not.

If I've programmed it before, what's new?  Before, it was only a Windows application.  The major limitation was that it had only a 3x3 grid.  In this 'new' version, the user can choose the grid's size. 

I programmed this in my spare time while waiting for a few basketball games to begin (I work stats at the games).  It was just to waste time beforehand, but I then became intrigued because I discovered my JavaScript and programming skills increased enough where I didn't need an editor to tell me of errors or proper procedure.  This is from memory, all by hand in notepad.

I will 'fix' it later to prevent people from stealing the script.  It's so easy to do.  Anyway, play it here until I add AJAX to it and make sure no one can steal it.
