Does 20Q use a decision tree?

Yes, 20Q uses algorithms that function like decision trees, asking yes/no questions to narrow down possibilities, but the physical toy and website actually employ more advanced neural networks that learn from user interactions, making them robust and improving over time, essentially building a complex, evolving decision structure. While traditional decision trees are tree-like structures, 20Q's use of neural networks allows it to handle more complex, subjective questions and learn from millions of past games, making it more adaptable than a simple, static decision tree.

How does the toy 20Q work?

The 20Q AI uses an artificial neural network to pick the questions and to guess. After the player has answered the twenty questions posed (sometimes fewer), 20Q makes a guess. If it is incorrect, it asks more questions, then guesses again.

What are the best strategies for 20Q?

Mathematically, if each question is structured to eliminate half the objects, 20 questions allow the questioner to distinguish between 220 = 1048576 objects.
