GeoGuessr is a game where the player is placed in a random location from Google Street View and has to mark where they are on the world map based on what they can see.
easyguessr makes this easier by allowing you to select specific filters relating to what you could be seeing in a game of GeoGuessr. Using these filters you can narrow down your guesses. For example the filter "left-hand traffic" will show you countries such as the UK, where people drive on the left side of the road. This can not only help you win a game of GeoGuessr, but also teach you how to do it yourself.
The information for these filters was taken from the following websites:
