Start by naming any country that France borders. Then name any country that borders any of those countries. Then keep going until there are no more countries left to name.
Nice quiz. Maybe add in description that Y is considered a wovel when at the end but not in the beginning of a word. This is really confusing for us scandinavians:)
P.s Everything you would write with J in swedish, finnish or german is a consonant in english (Yemen - Jemen). OR with I is a vowel in english (Italy - Italia,Italien).
