How many questions is Akinator based on?

Akinator is an artificial intelligence program that asks users 25 questions to guess a character or person the user is thinking of. Akinator uses a secret algorithm to narrow down choices after each answer and ventures a guess before 25 questions if a likely choice arises.

Akinator uses a database of public figures that users can update after the game is over if the guess was incorrect. Users can also add questions to the Akinator database to help improve the accuracy of guesses. Akinator is playable online or by using a mobile app downloaded from all major application stores and is available in multiple languages.
