Unless you're in a movie, the chances of you suddenly waking up one day in a random part of the world are fairly low. But if you want to live out your fantasy of being completely and abruptly lost, GeoGuessr is the game for you.
GeoGuesser is a game based on Google Street View that drops you onto a random spot in the world. From there, you're free to look around and explore the area to figure out where you are. The closer your guess is to the actual spot, the higher your score. Once you're done, you can share your score on various social networks.
