What is WhoInTen?

WhoInTen is a free online guessing game where an AI picks a famous person and you have exactly 10 yes/no questions to figure out who it is. Choose from categories like musicians, scientists, athletes, and more. The fewer questions you use, the higher your score. Play the daily challenge where everyone guesses the same person, or pick your own famous person and challenge your friends to see if they can read your mind.
