Twenty Questions

As tacky as it may seem, 20 Questions online is an amazingly addictive site. Just like you remember from your childhood, except it doesn't lie about the answers it gives and then tattles to Mom. It uses the results of others playing the game all over the world to narrow down your choice. It can guess whatever you're thinking to a surprisingly accurate degree. It just guessed "playing card" in 17 guesses. And go easy on it, guys. It's not a genius. It's just a computer. Check it out here.
