GeoGuessr is a game thatin which someone guesses whichere the position on the world map is from a landscape photof a landscape photo would be on the world map, and the closer you are to the actual position, the higher the points you get.

More natural to say "the more points you get."

Not only did they know the places' names well, but they (also) guessed the place based on the kinds of plants there, the characteristics of the phone numbers written on the signs, the material ofs for the roofs of the houses, the colors of the license plate of the cars, etc.

The game looks interesting, so I wanted to try it too.

I saw a video of the YouTube channel QuizKnock playing GeoGuessr and it was fun.

You can use "position" and "location" interchangeably. However, when we are talking about fixed things/ designated areas we usually use words like "location", "locate", "to be located in" etc. When talking about objects we usually use words like "position", "to be positioned in".

Not only did they know place names well, but they guessed the places based on the kinds of plants, the characteristics of the phone numbers written on the signs, therooftop material of the roof of the house, the color of thes, license plate of the carcolours, etc.

Don't need "well".

GeoGuessr is a game that guesses whichin which people guess the position on thea world map is from a landscape photo, and the closer you are to the actual position, the higher the points you get.

In the video, each member of QuizKnock was explaining how they guessed the position whilefrom looking at the photos.

"from" suggests they got the information from the photo "while" suggests they just happened to be looking at the photos when guessing.

Not only did they know place names well, but they guessed the place based on the kind of plants, the characteristics of thea phone number written on thea sign, the material of the roof of thea house, the color of the license plate of the car, etc.

Not a specific phone number / roof / sign you have already introduced so would use "a"
