Thanks for the feedback! I've added some examples to the instructions to hopefully clarify things. It's not about the alphabet, but rather any consonants that appear one after another in the name of the country, or any vowels that do the same. I understand the confusion, I hadn't thought about it from your angle.
As it's an interesting angle though, that you said could be a good quiz, I've made a quiz based on that concept too. Check it out here if you're interested. Thanks again :)
Cuba is valid but definitely has a "a" and a "b" next to each other also has "u" and "a" in it as well which would meet the aeiou
Samoa has no consecutive letters but is omitted
Could be a good quiz but either there are mistakes or I dont understand and would you clarify in the directions
