Like most other games, it’s really just practice and experience with the key giveaways. They recognize things that stand out, and are often unique to certain countries or regions. The color of the dirt, the traffic lines on the road, traffic bollards, color of license plates, the power pole design, the type of car the camera is mounted on, the quality of the photo itself, even the grass and trees can begin to look familiar once you play enough.
For example, in Tunisia there’s a specific type and color of follow car that was present during the photos being taken. In certain parts of Brazil there’s a specific type of reddish dirt that can give you a clue. In Colombia there’s a cross made of metal that supports the back of stop signs. In Mexico there’s octagonal power poles.
There’s a great website called geohints.com that catalogs all kinds of unique giveaways that can help you figure out where you are anywhere in the world!!
