It really depends on your definition of "solution". Many mazes have unintended shortcuts, some of which can lead to the exit. The black LE, for example, can be solved rather quickly due to CENSORED. Gold has the intended solution and the CENSORED solution. One of the discontinued mazes has no solutions at all. For the most part, play happens as Chris intended it. Wall hugging in an unfamiliar maze can inadvertently create a new path, but you have to use a significant (illegal) amount of force to do this. This is a bad thing.
