This website shows you the world, but doesn’t tell you where you are. GeoGuessr is a geography game that uses Google Street View to put the player in a completely random location somewhere on Earth, and then asks you to guess your location based on your surroundings. Sometimes clues can be found in the language on street signs, but more often it is left to the player’s knowledge of geographic and biotic features, like mountains or vegetation. The game takes you to five locations around the globe, and you use a world map and a pointer to submit your guess. Points are assigned based on how close your guess was to the actual location.

This game helps people learn how to identify geographic features, and how to observe the world around them for such features. The beautiful locations keep the average player engaged while also showing what makes a place memorable and identifiable. It also gives more experienced geographers a chance to test their skills. I would classify this site as a Tool of the Geographer, for both its educational and testing value.
