Mazes of Menace

The Mazes of Menace is the collective name for all the levels in the game. They can contain up to 81 levels, but not all will be present in every game.

Map

This diagram shows which dungeon levels the various special levels and branches can appear on. A branch is signified with a --. The Dungeons of Doom and Gehennom are technically branches, but appear contiguously as the main branch of the game.

Also note that, although they are not special levels per se, any levels between Medusa and The Castle have a 4/5 probability of being Mazes.

Interdependence

Whenever there are several possibilities for the length of a branch, the depth of a branch entrance, or a special level, they are

• measured from the top of the parent branch,
• are equally likely,
• are independent of all the other choices made in this graph.

Exceptions are:

• Mines' End is the lowest mines level.
• Sokoban always branches off just below the Oracle.
• The quest portal is always 6-7 levels below the Oracle.
• The depth of Fort Ludios is complicated, see its article.
• Medusa's Island is 1-4 levels above the Castle.
• The Castle is the deepest level in the Dungeons of Doom.
• The Vibrating Square is the deepest accessible level of Gehennom. Moloch's Sanctum is immediately below, and both fake towers are 1-4 levels above.

Each level can be special in at most one way, and (additionally) host at most one branch entrance. For example, this means the stairs to Vlad's Tower can be located on any special level except Juiblex' swamp and both Fake Wizard's Towers.
