dnd

The Game of Dungeons, also known as dnd due to its filename, is a computer role-playing game released in 1975. The name dnd is derived from the abbreviation "D&D" from the original tabletop role-playing game Dungeons & Dragons. dnd was written in the TUTOR programming language for the PLATO system by Gary Whisenhunt and Ray Wood at Southern Illinois University in 1974 and 1975. Dirk Pellett of Iowa State University and Flint Pellett of the University of Illinois made substantial enhancements to the game from 1976 to 1985. dnd is notable for being the first interactive game to feature what would later be referred to as bosses.
