This is a countries of the world quiz, but for every country, you only need to type in the starting letters that make it unique. e.g. Yemen you just need to just type in y, but for United Kingdom, you need to type in United K
For countries with United, Federated states, etc. you have to type in the official name of the country on Jetpunk.

(I'm guessing the list you used had them under the names Côte d'Ivoire and Burma.)
