GeoGuessr.com is a website that has one and only one goal. To get you to observe closely and figure out where you are. Of course most people know where you are but what GeoGuessr does is give you a location and using Google Street View you must look around, explore the area and then on the map on the right hand side take a guess of where that actually is. The closer you are determines how many points you get.
There is no log in, there are no real rules, you just explore, observe, research and then guess. You have 5 rounds to get the highest total amount of points and then it automatically starts over. Going through all five rounds (for me) took about 7-10 minutes. Of course, the more you play, the better you will become. This seems like a great activity to start a class. Go ahead and give it a whirl. I don’t think you’ll be disappointed.
