Smarty Pins

Google's engineers want to help you brush up on your geography knowledge. The company has taken its vast Google Maps database and used it to create a new game called Smarty Pins. The concept is extremely simple: Google asks you a random trivia question about a specific city or country, and you're tasked with dropping a pin on the right spot. Players can pick between six categories that influence the line of questions they're given. These range from arts and culture to entertainment fodder, and it didn't take very long before we ran into a stumper.
