Most of us can point to the USA, Brazil and Russia on a map but could you also pick out Nicaragua, Ghana and Taiwan?
Test your knowledge of the world's nations with this interactive quiz.
The aim is simple. Travel round the world, in 19 steps, by tapping or clicking on the countries we ask you to locate.
Get it right and you’ll move on to that country. Get it wrong and you’ll stay where you are, and have to try again.
There is no limit to the amount of incorrect guesses you can make.
There is a catch, though - you only have 240 seconds to complete the entire journey back to the UK.
You can zoom in on the map to find the smaller countries.
There are three difficulty levels to pick from but be warned - the hard level is really, really hard.
Happy travels!
