How to Play Contexto — Complete Guide
Contexto is an AI-powered semantic puzzle game where you guess a secret word by finding words with similar meaning — not spelling. Unlike Wordle (letters) or Connections (categories), Contexto ranks your guesses by how closely an artificial intelligence language model associates them with the answer. Our free online Contexto game rotates daily through a curated pool of 30 words, with unlimited guesses, color-coded feedback, and local progress saving — no login, no download.
Contexto Rules — How the Game Works
- Guess any English word in the input box and submit it.
- Read the rank: the AI ranks your word among ~80,000 vocabulary words by conceptual similarity. The secret word is always Rank #1. A rank of 50 means only 49 words in the entire language are closer.
- Read the temperature: 🟩 Green (top 300) means extremely close. 🟨 Yellow (top 1,500) means warming up. 🟥 Red means cold — try a completely different concept.
- Unlimited guesses: there is no guess limit and no penalty for wrong answers. Every guess is pure information.
- Daily answer: a new secret word is generated every day at midnight from a curated pool of 30 words.
How Contexto Ranking Works
Contexto uses word embeddings — the same AI technology behind modern language models. Each word becomes a vector, and every guess is ranked by the raw inner product (dot product) between its vector and the answer's vector, sorted high to low — bigger overlap, closer rank. Crucially, this measures context, not synonyms: words that appear together in real writing score highly. "Cow" and "milk" rank closely even though they aren't synonyms. "Bank" (river) and "bank" (money) collapse together. Understanding this quirk — that Contexto rewards association over definition — is the key to fast solves.
How to Win Contexto — 6 Pro Strategies
- Cast a wide net first. Your first 5–10 guesses should jump between wildly different concepts:
SPACE,WATER,EMOTION,POLITICS,ANIMAL,MACHINE. You are hunting for the first green anchor, not the answer. - Descend the hierarchy. Hit green on
ANIMAL(#200)? Drill down:MAMMAL→PET→DOG. Each level should roughly halve the rank. If a guess jumps worse, you took a wrong branch — backtrack. - Compare siblings. When two related words rank far apart (e.g., CAT #800 vs DOG #60), the answer lives in the better word's neighborhood. Siblings reveal direction; the gradient is the map.
- Think in contexts. Ask "where would I read this word?" Kitchens, hospitals, airports, libraries — Contexto's training data is the internet, so situational clusters (BREAD/BAKER/OVEN) dominate. Guess the scene, then the object.
- Use the sort toggle. Switch history between chronological and rank order. Rank order instantly shows your best anchor and how far each guess drifted — your personal gradient map.

Common Contexto Mistakes
- Guessing synonyms only. Contexto rewards association, not dictionary definitions. "Happy" and "birthday" can outrank "joyful."
- Ignoring the gradient. Players fixate on one green word instead of comparing ranks across guesses. Always ask: better or worse than my best?
- Skipping the sort toggle. Switch to rank order to see your best anchor instantly — and after a solve, the top-10 bar lists exactly which words sat closest to the answer, the fastest way to learn how this model associates words.
Why People Love Contexto
Contexto lets you peek inside an AI's "brain." Sometimes the associations are beautifully logical; sometimes they expose hilarious biases in how humans write online. It rewards abstract thinking and deep word-association knowledge, making it a favorite of linguistics fans, writers, and philosophy nerds. With 30 curated daily answers, unlimited guesses, and instant vector-powered feedback, our free version is the ideal training ground.
