You begin with two Europe countries/US states shown in the grid. Upon starting, your job is to sort the countries/states in order from largest to smallest by max elevation (so countries/states with the highest max elevation first). The order is represented by the '1st' thru '16th' in each box. You can click on a country/state to move it to a higher position in the list - simply click once and it will turn red, then clicked another higher-ranked country/state to position the first country/state before it. Click submit to check your answers...if they are in order you will get a new country/state added to the end which needs to be positioned correctly, and so on until you either get one wrong or complete all 15 levels.
PLEASE NOTE: Only the portions of each country geographically in Europe are counted to determine the highest points. So no Asian portion of Turkey/Russia, African portion of Spain/Portugal, Greenland, etc.

Should not Boise City be on here?
The one in Idaho I mean.
I don’t think there currently is a city named “Boise City” – there’s just “Boise” Idaho.
I’m not positive what the official name is, but my understanding is it is officially Boise City, Idaho. The city itself interchangeably refers to itself as the City of Boise (which would not count) and Boise City. The city code is specifically called the “City Code of Boise City.” The mayor’s Covid-19 public health orders have all been issued by the “Mayor of the city of Boise City.” The census designates it as Boise City, but that may be to distinguish it from Boise County.
I refer to it as Boise in all my quizzes. Even the city’s official website just says Boise so I will leave it as that.
Oklahoma’s seems to use the word City:

I so badly wanted “New Jack” to be a bonus answer.
No New York?
the city’s name is ‘New York’ – city is only added to distinguish it from the state…officially it is ‘City of New York’
