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.

An idea… to facilitate learning from the quiz without having to look everything up, once you’ve made a guess, a hint could show you a descriptor of how close you got “Boiling/Very Hot/Hot/Warm/Cold/Very Cold/ Freezing” or something like that.
Currently there’s no way to know when you make a guess if you were even remotely close, esp. since most of the ones people miss are going to be on the edges of the map. In NYC, if I get something I don’t know it most likely will be in Staten Island, far reaches of Queens or the Bronx. Those places are all far apart, so the next time, I’d be more likely to get in the right area, instead of just randomly clicking around.
