The World has been pixelated! Only pixels with at least 50% land have survived! Each pixel can only be guessed by the country which has the most area inside it!
There are no answer boxes on purpose! The pixel grid is your only resource to name all the countries!
Another fantastic suggestion by the one and only scambigol!
(p.s. you don't need to ask for mentions with me, if you suggested an idea you're definitely getting credit!)
