I just finished my second multi-maze. This one has three openings. By picking any one opening as a start and any other as a finish, you have six combinations of openings. In other words, this is six mazes in one! Each solution is relatively easy since I had to squeeze six different paths in the space of one maze.
I plan my next multi-maze to be the Starry Night maze I mentioned back in January. This one will have four openings: a 12-in-one maze!
