	3 minutes is fine. It's not the type of quiz you are really trying to finish, and too much gets a bit boring. Go 379!

	Can't believe some people can get 100% in 3 minutes.

	I now have blisters on my fingers from the burns I got while typing.

	I'd really like to know how some people got all of them. Hopefully, this quiz is like the video game in the Last Starfighter and those people are on their way to doing something much more important like saving the galaxy.

	Well, I was gonna use Eratosthenes' sieve for this quiz (aka cheat), but then I realized it'd probably take more time to write down all the numbers 1-1000 and cross out even numbers and multiples of 3, 5, 7, etc. than it would to just name the primes.

	You know, it's kind of a cool idea, but I found myself losing interest after about 20 numbers. Maybe fewer answers with a shorter time limit would work better.

	It becomes repetitive. I stopped thinking and started to punch in every odd numbers.

	Really made my day, this being published. Thanks, Sporcle!!

	I really lost interest. I got about 20, and then I gave up. It's a good idea, and it was good that it got published, but maybe there should be less numbers and a lower time limit.

	Wow...looks an awful lot like a quiz I made way back in 2009 (http://www.sporcle.com/games/tom/primenumber_blitz) Wtf?

	gedion:	Aug 31st, 2011 at 02:05 GMT		6 points
	Tom, you got ripped off.

	grambus:	Aug 31st, 2011 at 04:51 GMT		8 points
	so i started playing, got all of them up to 71, then looked at the timer and it was still at 3 minutes! weirdest thing ever. has this ever happened to anyone else??

	doctorwhofan883:	Aug 31st, 2011 at 10:47 GMT		4 points
	I got all of the numbers under 200 (I had to memorize them for a math test) and then 971, which I don't even remember typing in. I think it happened when I somehow forgot how to type 197 and 199.

	Dunnski:	Aug 31st, 2011 at 13:04 GMT		5 points
	All these years I've been cleaning my counters with a prime number! Who knew?

	mj75:	Aug 31st, 2011 at 20:29 GMT		11 points
	Dunnski: no big surprise there.. composite numbers break down too easily...

	Big_E:	Sep 1st, 2011 at 00:54 GMT		3 points
	i knew all the ones up to 100, after that it's just guessing odd numbers that end in 1, 3, 7 or 9. All prime numbers past 5 end in 1, 3, 7 or 9. (though obviously some numbers like 33 or 99 are not prime).

	EasyTarget:	Sep 1st, 2011 at 01:17 GMT		0 points
	All right, fess up. Who didn't get the number 3?

	mhaymo:	Sep 17th, 2011 at 16:19 GMT		1 point
	Wrote a script to brute force this by simply trying every odd number. I was bored, but not bored enough to actually write a program which would calculate the primes.

	theBCI:	Sep 26th, 2011 at 17:52 GMT		2 points
	13 is the most prime number!

	TheVoices:	Oct 2nd, 2011 at 22:23 GMT		0 points
	I just typed 2, 11 21 31 41 51 61..., 3 13 23 33 43 53 63..., 5, 7 17 27 37 47 57 67..., 19 29 39 49 59 69.....until I ran out of time.

	@Grambus This has happened to me several times! Really weird

	acabrrr999:	Dec 22nd, 2011 at 09:05 GMT		1 point
	Love it how higher numbers get gradually less popular, but suddenly 997 appears in the middle of the 300s. Do people get bored and start going from the top?

	Deion Sanders would love this quiz. Get it, his nickname is "Prime Time" and this quiz is about "prime" numbers.

	R4bz:	May 14th, 2012 at 06:01 GMT		1 point
	This quiz is way too long, i got less than half way before time expired
