GeoGuessr is an application powered by Google for Education that can either be played alone or with a friend. The way it works is, by using Google Maps, the program will drop you at some unknown location, somewhere in the middle of the world and you are tasked with the assignment to guess where you are.
Teachers can use this in the classroom as a simple free time activity or part of a lesson. This game streches the students use of deductive reasoning skills and makes them think about the geography around them to come up with the place that they were dropped in. Another cool thing about this app, is that you can narrow down the region that the program drops you in, so the teacher can place students in the region that they are studying.
