A maze pattern is generated by Depth-First Search (DFS) algorithm. To create more interesting/skewed maze, the probability to search for each direction, i.e. top, right, down and left is randomized. As a result sometimes it's more likely to go upward, if available, than right. This generator could be found in mazejs.
