A dungeon crawler with no story. The player builds a party of up to four adventurers from four classes — Fighter, Priest/Priestess, Thief, Sorcerer/Sorceress — and explores dungeons until all routes are exhausted, collecting experience and treasure while trying not to die. Completing a dungeon earns a bonus proportional to the dungeon's size. Between runs, the party returns to an unnamed town to buy and sell items, heal, rearrange the team, and save. Characters cannot share items or gold with each other. The goal is survival and thorough exploration.
