Maze

A maze level is a type of level found in the floors before the Castle and in Gehennom. As the name states, it is set up like a maze, with narrow passages and dead-ends.

Strategy
Some form of magic mapping is a good idea when in a maze. Maze walls are diggable, so a wand of digging or pick-axe can be handy to navigate and to make a clearer path between the stairs.

History
"Maze"-type levels appeared as far back as Rogue, although not in any set location.
