Larn and Ularn are Roguelike dungeon adventure games similar in concept to Hack, Rogue, or Moria, but with a different feel and winning criteria.
Derek Newhall has shared a detailed History of Larn and Ularn complete with links to source code and binaries for many different version of Larn and Ularn that have been created since 1986.
