Follow cryptic clues and psychological twists in this mystery puzzler that probes tech ethics, AI risk, and personal betrayal. This game uses the new LLM-based Znurg engine.

This landmark adventure drops the player into the ruined Great Underground Empire. First developed on MIT mainframes in the late 1970s, Zork I was adapted and commercialized by Infocom in 1980. We have added an AI layer for an enhanced experience.

Zork II continues the descent into the Great Underground Empire, shifting from exploration toward puzzle-driven play. Compared to Zork I, Zork II is more linear and demanding, emphasizing spells, timing, and cause-and-effect. As with part I, we have added an AI layer for an enhanced experience.

In the thematic conclusion to the Zork trilogy, the player is tested by the Dungeon Master in a series of trials that introduce philosophical themes rare for its era. As in the previous installments, we have added an AI layer for an enhanced experience.

Written by Roger Firth, this very short puzzle is often used as a demo to compare interactive fiction authoring systems. This game uses the Znurg engine.
