Nope, would be 22nd overall and would drop out of top30 if tributaries were counted separately.

All the quizzes I've seen used that spelling. I didn't know Yenisey was another spelling.

If you consider Rio de la Plata a river, wouldn't the Parana be part of its drainage basin and thus not counted separately?

That's true. Fixed to Rio de la Plata - Parana duel, so a new entry makes the list at #15

the Rio de la Plata isn't a river, but a sort of gulf or bay, so if you were to include it, it would be like including the entire Mediterranean Sea basin into the quiz.

I'm surprised the Murray/Darling river in Australia is not on the list, it covers a great area.

Can you accept Misisipi for the Mississippi river? That type-in is used all over this site. Can you also change Yenisey to Yenisei, it is the more commonly used spelling. Other than that, great quiz.
