The path is a series of loops interrupted by doors.
Through the use of reciprocal doors, the correct path can intersect the incorrect path on a single plane.
There are two main mechanisms used to generate mazes.
In "carving passages", one marks out the network of available routes.
A maze is a path or collection of paths, typically from an entrance to a goal.
The word is used to refer both to branching tour puzzles through which the solver must find a route, and to simpler non-branching ("unicursal") patterns that lead unambiguously through a convoluted layout to a goal.
Some of the best-selling books in the 1970s and early 1980s included those produced by Vladimir Koziakin, Rick and Glory Brightfield, Dave Phillips, Larry Evans, and Greg Bright.Although the routing was comparable to or simpler than Koziakin's mazes, the Brightfields' mazes did not allow the various pathway options to be discerned easily by the roving eye as it glanced about.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.
In building a maze by "adding walls", one lays out a set of obstructions within an open area.
