My tip for doing this: Click the countries on the map, then click the word in the left column. DON'T follow the given order. Whenever a country is guessed (whether wrong or right) it is not clickable any more. So, at first guess all the big ones which you can click by yourself - make sure that you click the right one! Afterwards you can guess those which can be seen but not clicked properly. And finally you can do things like the European Micronations and the Lesser Antilles. Do the latter from top to bottom and use the zoom function of your browser. Magnify the map as big as possible. Good luck.
To the one who made this: Arrows would help enormously!
the color that is the new country to guess should stand out more and you can add an arrow so we can see where you are pointing to it does not give you the answer
