"This is a modifiable dungeon-crawling game for 2-4 players." One player takes on the role of the Dungeon Master. The other players each control a Hero who is exploring the dungeon. The game uses three to five custom card decks: a DM Deck (60 cards), a Dungeon Deck (30 cards), and a Hero Deck for each Hero player (60 cards.) The Dungeon Deck consists of cards specifying rooms and passages which are used to randomly create the dungeon. A Hero Deck consists of cards for various actions and treasures. The DM Deck consists primarily of cards representing monsters and traps. The Hero players win if the Objective room card is located and resolved. The DM player wins if all of the Heroes are killed before they resolve the Objective room.
