Can you really count two word country names that end in two consonants and start with a third? I was going to put czech republic, but i didn't because i didn't think it kept with the theme of the quiz.
What about 'Y'. I know some people consider it a vowel but it isn't a traditional vowel with a,e,i,o and u. If y is a vowel you then must allow Egypt, Syria, Cyprus, Seychelles and Ivory Coast (unless you stick with Cote d'Ivoire).
