What is "dungeon!"

Dungeon! is a 1975 adventure board game designed by David R. Megarry, Gary Gygax, Michael Gray, Steve Winter and S. Schwab, published by TSR, Inc. Dungeon! simulates some aspects of the Dungeons & Dragons (D&D) role-playing game which was released the year before, although Megarry had a prototype of Dungeon! ready as early as 1972.

Dungeon! features a map of a simple six-level dungeon with hallways, rooms and chambers. Players move around the board seeking to defeat monsters and claim treasure. Greater treasures are located in deeper levels of the dungeon, along with tougher monsters. Players choose different character classes with different abilities. The object of the game is to be the first to return to the beginning chamber with a set value of treasure.
