See if you can name every country in the world over at sporacle.
You get only seven minutes, but the game will help you out tremendously by automatically naming every country that borders the ones you type. So just entering “Russia” will also get you credit for Norway, Finland, Estonia, Latvia, Belarus, Ukraine, Azerbaijan, Georgia, Kazakhstan, China, Mongolia, and North Korea. Plus Lithauania and Poland. You forgot Kalingrad was over there, didn’t you.
I managed only 158 of the 195 countries included (since some disputed territories like Palestine and Western Sahara aren’t counted). I think that’s a B minus, though if my math is as rusty as my geography it could be anything.
Think it’s too easy having all the bordering countries handed to you for free? Not to worry! You can also try to name all 195 countries without any hints in 15 minutes. You do at least get to see a blank world map there which is labeled as you go. I managed only 150 countries there.
If you’re discovering you need to brush up on your geography skills, I recommend the games over at Sheppard Software. They’re designed to teach, not quiz. You can choose a region (either a whole continent, or just a few countries at a time) and then click each country as its named appears and is spoken. If you miss (twice) the game will show you where the country is so you can learn quickly from your mistakes.
Maybe with enough practice you’ll be able to identify all the countries by their capital city.
