@gustavratzenhofer,
I got 158 0ut of 162, but then I'm a total maps geek.
I didnt get Equitorial Guinea even in three guesses, and I only got Burkina Faso on my second try (clicked Mali first), which is silly cause my sister went there for a documentary.
I did have some luck - eg while looking for Eq. Guinea I wrongly clicked Sao Tome & Principe, which helped me locate it further along in the quiz when otherwise I would probably have made a mistake.
