GeoGuessr is an online game that challenges people to locate specific places in the world based on the environmental cues of Streetview. The mechanics are rather simple — you move around a Streetview environment stripped of all its informational overlays looking for clues that indicate where you are. Once you think you know, you mark the spot of your original starting location on the inset map. The closer you are, the more points you get. A game consists of five locations.
