Should Parana be Rio de la Plata, on the same basis as Shatt al-Arab? Anyway, fun quiz. Got the first twelve without missing one and then nine of those remaining. Embarrassingly I missed Murray, despite being Australian. Broadly the equivalent of an American missing Mississippi.

Also - Wikipedia now lists the Amazon as longer than the Nile (6992 km for Amazon, 6853 km for Nile).

In this case it doesnt matter much. But when it is about distance between cities it does. (no matter how other try to bash it and say well relatively it is still the same like 10-50 is relative with 16-80. But that is just trying to be hatefull for the fun of it because that is not how the mind works. Or when it is about height of people for instance, yes, you see 5.6 is less than 5.8 but it doesnt mean a thing, one could mean 1.20m and the other 2.20... It doesnt give you a picture in your head you can use. That why in this case it really doesnt matter, because I dont have pre-existing pictures in my mind about the length of rivers, just big bigger biggest.)

I propose that all lengths should be quoted in furlongs. Then, for those that can only compare lengths in kilometers, they would simply have to divide the figure by 5 to get a good approximation, rather than having to multiply by 8 first.

Hi there. What, specifically, is misspelled? I took a look at your quiz, and the list looks very similar except that you include tributaries. In my opinion, Wikipedia is usually the best source for things like this because the information can be vetted by multiple people. Additionally it is almost always more current.

Rio de la Plata should be accepted for the Parana river. That's the mouth of the Parana after it merges with the Uruguay River.

Shatt Al Arab is listed for Euphrates and that's also just the mouth section after it merges with the Tigris. So that's equivalent.

I don't like this quiz at all. Please add kilometers! Most of the world does not understand miles. What is the source? Wikipedia has the Nile at #1, and most definitions of river agree, as do all other sensible lists. Why cite a source if you do not follow it? And why the random cutoff at 28? Please add more type-ins, I typed Rio de la Plata and did not get Paraná, for example. Still got 24 on first try though.

Hmm - 21 on first go and I missed the Lena. The russian rivers are OK as long as you are careful to go from west to east in order. Main problem was why no Irrawaddy - maybe it has shrunk. I never get the Rio Grande becasue it doesn't show on maps becasue of the very thick border, and perhaps a Wall! :-)

I would have got all of them in my youth - many years ago - although never sure where the San Francisco is.

I have some problems with that list, because it's just the first river copy-pasted from wikipedia. For instance in the Ob-Irtysh river system, the Irtysh is longer than Ob, yet it is not present in the quizz, or at least it isn't accepted as an answer, that would count into the Ob answer. The list is basically wrong, because it's not complete - a river system is a system of rivers, not a river, the tributaries don't count separately, I understand, but they should count as an answer for the river they contribute to, especially if they're longer than that river. Either change the title or change possible answers please.
