To make country appear in world map, you don't have to type them in. Instead, you have to type chemical elements whose two-letter symbol are contained in that country name. For example, for the fictional country Foodistan, you have to type Tantalum (whose symbol is Ta).
For several countries without any two-letter symbols in their names, you have to type any one-letter-symbol elements in.
missed japan and kosovo, and i can’t think of what element would have filled them in - perhaps when you finish the answers should show elements rather than countries? love the idea though!
I think there's a mistake with Uranium: typing it gives you Chad, Chile.. also, perhaps you could force the 1 letter element to be part of the country name? Eg Tungsten would get you Sweden
You should add to the answers a hint with the elements valid for that country. I got really curious about the ones for Peru and Egypt. Ok, I could only Google it - as I really did -, but would be nice to see for all other countries as well. Even if it was just the two letters, not the full name.
Kosovo : Os for osmium.
