Can I cover the entire world map in circles by naming towns and cities??

We've (almost) covered Europe, the USA and Britain and now it's time for the big one: THE WORLD This is the ultimate test in worldwide city knowledge. How much of that iconic world map can I cover by naming towns and cities with a population of 50k plus? Okay so the title isn't completely accurate as the map can't be completely covered, but here's how this thing works.. Pick your level (beginner, intermediate, advanced or expert) and simply name as many 50K+ populated towns or cities as you can think of. As you do so, the map will become covered in circles. Keep going until you have unlocked all the towns or cities. I'm expecting that areas such as Siberia, the Sahara and the Amazon will be pretty devoid of circles, all I can hope for is that I don't miss out any of the world's major cities...
