Maze Generator 8

[SierraKen]

Like the others, this one doesn't find a path. And like the others it randomly puts walls and exits. But I think this is my best so far. Check out the picture to see what kind of maze it makes. Since it doesn't find a path, maybe 1/4 or so of them doesn't work, so just press the Space Bar to make a new one. I also added clipboard to it so people can copy it using the C key (not CTRL C, just C) and then paste it into their favorite graphics program to save or print. Like my other ones, it's a white background with black walls. I made a similar one I think last Summer using circles instead of boxes, but this one looks more like a regular maze.

Here is an update. I did it 38 times before I got a maze that didn't have an ending. It makes easier mazes but I like this one better. Here's a picture of this one below. I hope some of you use this.

I decided to make it more than double as hard with 10 pixel hallways instead of 25. This one is more fun to use. After 13 mazes it got to one that didn't have an exit.
A picture of this one is also below.
