/play/20q — 20 Questions
Think of a thing — an animal, a food, a vehicle, a musical instrument or something you have around the house — and the computer tries to name it in twenty yes/no questions. It picks each question by information gain, so it zeroes in fast, and it weighs your answers softly: one slip will not derail the round. Everything runs in your browser. When it loses you can teach it, and what you teach stays in this browser only.

I think I have it.
You win. I give up.
