Over the years, Word Ways has presented several articles on word chains and networks. It was obvious that the networks could be developed into mazes, but I, for one, did nothing about it because I considered mazes kid stuff. However, John Harris sent me a copy of a maze by Robert Abbott that appeared in the May 1991 Discover magazine which is not kid stuff.
