After releasing V4.8, released 1986 or 1987, Koeneke and Todd stopped further work on Moria and gave permission to others to work on the game. Moria V1.0 was released around 1983, and in 1985, Koeneke released the source code code for Moria V4.0. They were developed by Robert Koeneke with some help of Jimmey Todd, both students at the University of Oklahoma, inspired by playing the original Rogue. The first implementations of Moria are called VMS Moria, as they were written in VMS Pascal running on a VAX.

The dungeon levels are randomly generated. You can barter with the shopkeepers to get reduced prices. You start in town, where you can visit several shops to buy weapons, armor, torches, food, and other useful - and sometimes magic - items. The game is entirely played in turns, features text-only graphics showing your environment from above, and is played by entering character commands. After entering a name, you're ready to roll. You can then roll your stats and, when you got some which suit you, choose your class from six available classes (you can only some of them, depending on your stats).

You begin the game by creating your character, choosing your sex and one of eight available races. Other than this, there are no other references to J.R.R.

The goal of Moria is to descend in the dungeons of Moria and defeat the evil Balrog who is cowardly hiding on the lowest level. It features several innovations, like a town level and dungeons levels that are bigger than one screen, and was the first open-source and freeware roguelike.
