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.
hugequiz Premium members will see country/state max elevations when the quiz is over.

I would love to see quizzes for the Prague, Budapest and Warsaw metro. I am so bad at the western European ones except for the Dutch ones.
I’ve added them 🙂
That’s amazing, you’re the best!
Please do one for the rotterdam metro too!
Here you go!

Nice to see those metro quizzes coming! Just one remark about this one – Sixhaven station was never built, although they left some extra space so that it could be finished and opened later. That is however not likely to happen anytime soon.
I will remove it – thanks!
