Unicursal maze

Simply-connected maze

Multiply-connected maze

A multiply-connected maze contains one or more passages that loop back into other passages, rather than leading to dead ends. A well-designed multiply-connected maze is more difficult to solve than a simply-connected maze, for users will spend a great deal of time simply going around in circles. The ideal multiply-connected maze has no dead ends at all, and is called a "Braid maze."

A weave maze has pathways that go under and over each other. Though often drawn on paper, it in fact exists in more than two dimensions and can easily foil some common maze-solving tricks and techniques. An outdoor maze that has bridges or tunnels is a partial weave maze.

Planair maze

A mind-bending maze whose underlying topology is unusual (non-Euclidean) and which has edges that connect with one another. For example, mazes covering the surface of a cube, sphere, torus, or a Moebius strip would all be planair mazes.

Logic maze

A maze that must be navigated by adhering to logical rules in addition to following its passages. Examples might include a maze containing different colored symbols that must be passed in a certain order, or a maze that has some passages that may only be followed in one direction (an arrow maze).
