Question 1

How does AI 20 Questions work?

Accepted Answer

The AI uses Shannon entropy from information theory to select the optimal question at each step, maximizing information gain. With 180 items across 6 categories (K-Food, K-Pop, Animals, Tech, Places, Memes) and 108 property-based questions, the AI typically guesses correctly in just 4-6 questions — far fewer than the 20 allowed.
