Play the classic game of 20 Questions against an AI, free and without sign-up. Think of anything — an animal, an object, a food, a famous character — and watch it narrow down the possibilities one numbered yes/no question at a time. Or flip it: the AI locks in a secret and you do the guessing.
Mode A: you think, it asks — one yes/no question per turn, counted out of 20, with guesses that cost a question when wrong. Mode B: it commits to a secret and answers your questions honestly until you crack it or run out.
The AI plays properly: broad questions first, logical narrowing, no repeats, no cheating, and a dramatic concession when you actually stump it — which is harder than you think.
Best of three, running score, themed rounds (animals only, foods only) — just ask. Every round is free and every secret stays family-friendly.
