DEDICATED FANS of Google Street View, which lets users explore cities and towns around the world via panoramic street-level imagery, have come up with dozens of applications for the tool, from house-hunting, to holiday planning, to experimental art. The most entertaining use of the service may be “Geoguessr”, a game created in 2013 by Anton Wallén, a Swedish IT consultant. The premise of Geoguessr is simple: players are dropped at random places in Google Street View, without any information about their locations. They are then scored based on how well they guess where they are.
