Page "Maze" Paragraph 41

Greg Bright's works went beyond the standard published forms of the time by including " weave " mazes in which illustrated pathways can cross over and under each other.

Bright's works also offered examples of extremely complex patterns of routing and optical illusions for the solver to work through.

What Bright termed " mutually accessible centers " ( The Great Maze Book, 1973 ) also called " braid " mazes, allowed a proliferation of paths flowing in spiral patterns from a central nexus and, rather than relying on " dead ends " to hinder progress, instead relied on an overabundance of pathway choices.

Rather than have a single solution to the maze, Bright's routing often offered multiple equally valid routes from start to finish, with no loss of complexity or diminishment of solver difficulties because the result was that it became difficult for a solver to definitively " rule out " a particular pathway as unproductive.

Some of Bright's innovative mazes had no " dead ends " – although some clearly had looping sections ( or " islands ") that would cause careless explorers to keep looping back again and again to pathways they had already travelled.
