I am very blind, It took me a handful of tries before I could guess all 10 countries, also I lost a BUNCH of time trying to spell Azerbaijan and Kyrgyzstan. Another thing that happened was that I kept checking to see if Singapore was missing, and sure enough, it never was. I give this quiz a 10/10. And myself the taker of the quiz a 4/10, because I just cant see anything. Sincerely, Bob.
