Actually a genius idea. I would be excited to see more of this type of quiz!

cool, but i feel like it's a little generous, at least with 5 whammies to use up.

Easier than expected, a full world one could be a good way to learn the approximate population of countries.

Great quiz but the 1 digit off made it too easy in my opinion

I agree. I used no whammies, and was off by quite a bit for a few of them.

I think rounding is reasonable for them, but I put 4 for Nepal and it counted it.

Do people really have these numbers memorized - or at least know them well enough to guess the first digit? If I go by statistics for the quiz, that clearly must be the case. Besides China & India (gimmes) and the USA, anything else would be a pure guess for me. You could give me 5 whammies for each country and I likely still wouldn’t get 100%. While I’m generally good at math I’ve always told people that I am terrible at remembering numbers. I just never realized how much of a blind spot that is for me until this quiz highlighted it.

What's strange, I'm, on the contrary, mediocre at maths, but have a pretty good memory on specific digits, so this quiz was surprisingly easy to me.

Ithis quiz has a really cool idea, I think, but maybe it's a bit number geeky (exactly, my choice). So I can't wait to see second part of this!

I didn't explicitly try to memorise these, but I've looked at the numbers often enough to have a very good sense. Didn't have to use any whammies, and I could do it for almost all countries I think.

Can only speak personally but I knew about half of them including a couple of possibly obscure ones (the population of Mongolia is talked about on a radio advert that's running here at the moment that I hear several times a day), and was able to make educated guesses on the others so got them all with two whammies left.

I like learning about each country, which kinda includes knowing the rough population

I have a pretty good estimate after a lot (and I mean a LOT) of Jetpunk quizzes... since a lot of these are more "well-known" ones. I couldn't tell you the population of Burundi or Vanuatu off the top of my head for my life.

Without the quizzes, I'd be where you are, so I don't blame you one bit! That's how we learn :)

Maybe a bit less time would do! It is a bit easy at the moment. Maybe a minute and a half or less would add some pressure!

Nepal has a lot in common with India it's not just Mt. Everest and Sherpas. We have pollution and political corruption too!

Nepal is very mountainous, but what isn't is mountain is generally very fertile land fed by snowmelt from the Himalayas... and it's right next to the most populous subdivision on Earth.

Uttar Pradesh, I kid you not, has a staggering 240,000,000, which is more than every country in the world besides China, India (duh), the US, Indonesia, & Pakistan. I hate to sound Malthusian - especially as an Indian-American - but that's genuinely a massive problem. (UP is infamous for being one of the most underdeveloped, dare I say, backwards states in India; it's quite a shame)

That and the fact that Nepal's a poorer, more agricultural country on the world stage likely means it hasn't progressed through the Demographic Transition Cycle earlier on, like many Euro nations have

Me reading all these comments about Nepal being surprising as a Nepali.

I thought everyone in here knew Nepal is fairly well populated like its neighbors despite being mountains.

For most of us, Nepal is just a bigger Bhutan. But for the true JetPunk nerds like me who study these things, we know it's somewhere around 30 mil. I typed 4... and still got it right.

I think most westerners just kinda don't know much about Nepal and think it probably doesn't have many people because of all the mountains. As an American I thought you guys had around 25 million but that's only because I'm kind of a population nerd

Great quiz, but I do have one question. This generally affects "smaller" numbers but when you say "off by one" do you mean by one million or ten million?

I plugged in 3 for Australia (aka 30M) which was accepted, which is off by smth like 11% of the current Aussie population! Similarly, 4 (aka 40M) was accepted for Saudi Arabia, which is off by 5M people off by smth like 15%!
