Akinator, a 'game' that combines 20 questions with a wiki search engine.
The object is to think of a person and play until akinator guesses who your person is. It seems that depending on who you pick, whether or not akinator will guess right is based on the questions asked and the databases of answers.
Can you stump the genie who thinks he's a man? Well if you do then you can add your person to his database and claim your three wishes. Hit up the link below to take advantage of this deal in the Amazon Appstore for Android.
