Twenty Questions

How to play Twenty Questions

Twenty Questions on this site is an original yes-or-no guesser. You silently pick something from everyday life — an animal, a food, an item of clothing, a vehicle, a piece of furniture, or a simple object — and answer a series of questions with Yes or No. The game walks a decision tree that lives on this page. It does not call a live model, an internet API, or a paid service, so your answers stay in the browser and a round works even when you would rather not send data anywhere.

The tree is only as good as the path you give it. Answer the question that was asked, not the question you wish it had asked, and try not to overthink edge cases. If the tree names what you were thinking, you add to a streak. A wrong guess ends the streak, and you can start again with a new secret. Because a round is a short conversation rather than an action game, it is easy to play at a desk without much noise or motion on the screen.

Tap Yes or No after each question. Fewer questions and a correct guess are the goal. There is no download and no account.

Tips

• Pick a specific, ordinary thing — “a bicycle,” not “transport” — so the questions have a clear answer.
• If a question is slightly ambiguous, choose the answer that is true in the most usual sense of the word.
• Start a new round after a miss instead of reusing the same secret; the tree follows the answers you give, not your intention.

Controls: mouse, touch. No download and no sign-in required.

FAQ

Does Twenty Questions use ChatGPT or another AI API?

No. It walks a decision tree written for this site. There is no live model call and no paid API, so a round can be played without sending your answers to an outside service.

What kinds of things can I pick?

Everyday subjects work best: animals, foods, clothes, vehicles, furniture, and simple household objects. Very abstract or extremely obscure ideas may fall outside the tree.

Is it free to play?

Yes. Open the page and answer Yes or No. No download or account is required.
