It's called GeoGuessr (I can't post a link, but you'll find it). You find yourself in Google Street View, somewhere on the planet. Your challenge is to drop a pin on a map designating your initial location; the closer you guess, the more points you earn. You cannot exit Street View to a map, but you are free to "drive" around in search of clues. A game comprises five location challenges. Feel free to use any online tool at your disposal, although I think dropping a screenshot onto Google Image Search would be cheating. So far, I've reached the 31,500 range, but can't seem to break 32,000. Budget about an hour for each complete game. Addictive, isn't it?
