It's a fun game called Stolen!. Only for ios atm but its a game where you sign in through twitter, and you get to steal your friends twitter handles for a certain amount of credits (depending on their networth). Think of it like stock. If you purchase someone, it will cost you credits. If someone steals that back instantly, you get your credits spent back and some extra credits depending on how much you purchased said person for. If you purchase someone, and nobody buys it for a while, "stock" or how many credits the person is worth will go down. If somebody steals it from you at a low point, you will end up getting less money back.
Pretty fun imo.
