Zork I: The Legendary Text Adventure Classic
Zork: The Great Underground Empire is one of the most foundational and influential video games in history, created by Tim Anderson, Marc Blank, Bruce Daniels, and Dave Lebling at MIT in 1977 and published by Infocom. Standing in an open field west of a white house with a boarded front door, your epic journey begins.
Driven entirely by a sophisticated natural language text parser, players type English commands—such as "open mailbox", "take sword", "light lantern", and "go north"—to explore the sprawling subterranean ruins of an ancient magical empire.
Collect twenty legendary treasures and place them inside the trophy case in the white house, solve intricate puzzles involving dams, floodgates, and magical spells, and heed the timeless warning: "It is pitch black. You are likely to be eaten by a grue."
How to play Zork: The Great Underground Empire
- Type full-sentence English commands into the text terminal (e.g., "take all", "open door", "examine chest").
- Use compass directions ("north", "south", "east", "west", "up", "down") or abbreviations ("n", "s", "e", "w") to move.
- Always keep your brass lantern lit when entering dark caves to prevent being devoured by grues.
- Collect ancient treasures and return them to the trophy case inside the white house to score points.
Tips for winning and high scores
- Type "verbose" at the start to ensure the game prints full, detailed room descriptions on every visit.
- Draw a physical or digital map as you explore; underground maze rooms wrap around in confusing directions.
- Type "inventory" (or "i") to check what items you are carrying and manage your limited carrying capacity.
- Save frequently by typing "save" so you can reload if an encounter with the Thief or a troll goes awry.
