Watch it make a maze! The green in the bottom left is the beginning of the maze and red is the end. Black squares are walls. Can you solve your maze? Go look at my newer one with a solve button that will come up with a solution. Go look at the newer version with a solve button to show you the solution! http://scratch.mit.edu/projects/41654632/
This uses the Randomized Prim's algorithm. I got the algorithm from http://en.wikipedia.org/wiki/Maze_generation_algorithm#Randomized_Prim.27s_algorithm With very large mazes, like the biggest, 360 by 360, the red dot that marks the end can be hard to see.
