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.

Hi, one more suggestion. Idk if its possible but with two communes with the same name only one name is showing on the map, the other is popping but only colouring red without name.
Thanks for fixing the previous issue!
Little bug to fix: not every correct guess shows on map. Some are not visible and some only partially (eg. olny city area of a comunne).
Yeah I think it’s the outlines not being 100% complete. But it’s the only one I could find that is current with the current communes.
Maybe this would work: https://www.geoportal.gov.pl/pl/dane/panstwowy-rejestr-granic-prg/ (official SHP file on the bottom of the page)
