Dee Pee is a cleverly designed game that tests you on how well you know your Facebook friends. It does this through a quiz style game that randomizes your profile pictures and at the end provides you with a full list of the ones that you don’t know.  Just login through your Facebook login credentials and enjoy the game of knowing your friends. If you get stuck in between the "Hint" option (bulb like picture) is there to help you out with the quizzing. After the game is over there is the option to find out the "Unidentified" friends whom you failed to name during the game. Play again and again and enjoy.
