### GeoSettr - Create a Street View Geography Game

GeoGuessr is an addictive geography game that has become quite popular since its launch earlier this year. Now you can create your own GeoGuessr game by using GeoSettr.

When you visit GeoSettr you'll see two screens. A map with a Pegman on your left and the Street View imagery for the Pegman's current location on your right. Move the Pegman around, zoom-in if you like, until you find the location that you want people to guess. When you've found the right location click "set round" to save the location. When you've set five rounds (locations) your game is assigned a URL that you can distribute.

Just like any other GeoGuessr game when someone plays your GeoSettr game he or she will try to use the visual clues in the Street View imagery to guess the location. After making a guess GeoGuessr shows you the correct location and how far away from the correct location your guess was.

Applications for Education
Creating and playing GeoGuessr games could be a good way for students to learn about notable landmarks in their towns, counties, states, provinces, and countries.
