Guess-the-Verb — Definition, examples, FAQs, and more

Guess-the-Verb: a brief history

The problem is as old as parser games themselves. Colossal Cave Adventure (1976) and the commercial text adventures of the late 1970s and 1980s ran on small vocabularies, often simple two-word parsers, so players constantly ran into actions the game could not understand. Magazine hint columns and playground rumors about “the right words” were part of gaming culture in that era.

As a named term, “guess the verb” generally took shape in the interactive fiction community. By the 1990s it was in regular use in Usenet discussion groups devoted to text adventures, where it was already treated as a recognized design flaw rather than a legitimate kind of challenge.

Modern authoring systems such as Inform and TADS were built partly in response to it. They ship with large standard verb sets and easy synonym support, and the community norm of thorough beta testing exists in large part to catch missing phrasings before a game is released.

How it's used today

Today the term shows up mostly in reviews and design discussions of parser-based interactive fiction. Saying a game “has guess-the-verb problems” is shorthand for a poorly tested or under-implemented parser. It often appears as a modifier, as in “a guess-the-verb puzzle” or “a guess-the-verb moment”.

Players of MUDs and similar multiplayer text games use it too, since those games also depend on typed commands. The practical advice attached to the term is consistent: examine things for hints about intended actions, try common synonyms, and check the game’s helpfile or verb list if one exists.

Types of games where the term is commonly used include:

Interactive fiction, text adventures, MUDs and other parser-driven multiplayer text games

Guess-the-Verb examples

• You stand at a jammed door holding a crowbar. “pry door”, “force door”, and “open door with crowbar” all return “That’s not a verb I recognize.” The game wanted “lever door open”.
• You have a candle and a lit match. “light candle” and “burn candle” both fail. After several minutes you discover the game only understands “ignite candle”.
• You try to pay a shopkeeper with “give coin to merchant”, “buy bread”, and “offer coin”. The only phrasing that works is “pay merchant”.
• In a MUD, “hide behind curtain” and “go behind curtain” both fail, and you eventually learn the game expects the bare command “hide” while standing in the right room.

Myths and misconceptions

1. If a command fails, the action must be impossible. Often the action is entirely possible and even required to win. The game simply expects a different word for it, which is exactly why the situation feels so unfair.
2. Guess-the-verb puzzles are deliberate challenges. Almost never. Authors and players alike treat them as bugs. A well-designed puzzle challenges you to figure out what to do, not to guess how to spell it out.
3. Only old games have this problem. Modern authoring tools reduce it a great deal, but any parser game can ship with missing synonyms. Newly released games still get patched after players report failed phrasings.

Guess-the-Verb FAQs

What does guess the verb mean in text-based games?

Guess the verb refers to the situation where a text game rejects every reasonable phrasing of an action because its parser only accepts one specific command word. The player knows what to do but has to guess how the game wants it typed.

Why do guess-the-verb problems happen?

A parser can only understand words its author programmed in. If the author implemented an action under one verb and forgot to add synonyms, every other natural phrasing fails. It’s usually an oversight or a lack of testing, not a deliberate choice.

How do you get past a guess-the-verb puzzle?

Examine the objects involved, since descriptions often hint at the intended action. Try common synonyms (push, pull, turn, move, use), check any help or verbs command the game offers, and if all else fails, look for a walkthrough. Getting stuck on phrasing isn’t a failure of skill.

Is guess-the-verb a sign of a bad game?

It’s widely considered a design flaw, but context matters. Very old games had tiny vocabularies because of hardware limits. In a modern game, where authoring tools make synonyms easy, frequent guess-the-verb moments usually point to insufficient testing.

How do game authors avoid guess-the-verb problems?

They add synonyms for every important action, write error messages that steer players toward valid commands, and run beta tests where other people play the game and report every phrasing that failed. Modern systems like Inform also provide large built-in verb sets as a starting point.
