19 Questions Game
20 Questions is a game of deductive reasoning. It became popular in the 1940s when it was the subject of successful radio show by the same name.
One player -- the answerer -- thinks of a subject that should be familiar to common people and answers all questions about this subject with a yes or no response. The other player(s) ask questions to guess what this is, winning if they guess without exceeding 20 questions.
Inspired by 20q, the game by Radica, I set out to create a better computer program that could play this game. The new game, 19 Questions, strives to use a better mathematical model (likelihood and entropy rather than neural networks) to play the game.

This also works very well on the iPhone.
