Object:
Move the marble from the top left corner to the bottom right corner. You can move one square at a time. Every time you move into a square, the walls of that square flip from open to closed (and vice versa). If you find yourself unable to move the game is over (you lose!)
 
History:
This maze is based on the 'Turn Off' (or 'Lights Out') idea. It was designed and implemented by Matthew Baker in 2000. Randomized set-ups added by K. Franklin June 2003.
