	I got 28 on first try, got 30 now with 0:29 left. Tight time limit. xD

	30/30 w/ 9 seconds. But i really don't like the ones where you can just guess...

	Tony:	Dec 11th, 2008 at 23:54 GMT	0 points
	30/30 with 0:44, not that hard. Just gotta guess all odd numbers that dont end in 5, or divisible by 11. Theres not that many.

	A lot more fun when you actually try to thing of them as opposed to just guessing every odd number that doesn't end in 5. Of course, I was a math major (among others), so I'm also a nerd regarding crap like this. Still, I had a good time.

	Took me ages to work out why 51 isn't a prime number. Not familiar with my 17 times table.

	TRad:	Dec 28th, 2008 at 17:57 GMT	7 points
	Catherine Forget 17. 5+1=6=3*2, so 51 is divisable (is such a word in English?) by 3.

	davidr:	Jan 3rd, 2009 at 14:16 GMT	5 points
	@TRad: Yes, it's a word but it's spelt "divisible".

	Good quiz. Did it with 3 seconds to spare! Very Hollywood!

	Qrystal:	Jan 26th, 2009 at 13:28 GMT	1 point
	That was tense! I had only 2 seconds left when I got to the end! I started out by memory, but never really memorized this many of the primes so I had to resort to guessing. The short time limit is perfect, IMHO!

	Etheridge2:	Jan 31st, 2009 at 03:24 GMT	-2 points
	at first i didn't think i would have enough time but got them all with 2 seconds to spare

	Skydog:	Mar 14th, 2009 at 17:18 GMT	-2 points
	:) Got them all on first try

	Victor2K:	Apr 2nd, 2009 at 02:08 GMT	-2 points
	finished with 00:24 left Just good game to spend time

	Mae:	Apr 27th, 2009 at 03:42 GMT	0 points
	got them all, too...

	emabears23:	Apr 30th, 2009 at 21:50 GMT	-2 points
	Needs more time, that was my only problem

	bleech128:	May 5th, 2009 at 00:54 GMT	0 points
	easy, just type faster, can't end in 5 or even #s is the only thing you gotta remember

	krozza:	May 5th, 2009 at 15:07 GMT	4 points
	got 'em all with a second to spare, i panicked and couldn't hit the '9' in 139, kept hitting 98 or 09 lol

	katie:	May 21st, 2009 at 12:43 GMT	1 point
	doesnt need more time. i've never even learnt the prime numbers and i got them all in the time limit. just use your brain - you can easily guess most numbers ending in 1 or 7. it's actually quite easy.

	lavraiemusicienne:	Jun 1st, 2009 at 15:18 GMT	1 point
	I thought the time was too long - I only knew the ones for definite until the 40s and just guessed after that, still got them all. I'd love to see a longer one though.

	Erika:	Jun 3rd, 2009 at 15:57 GMT	0 points
	Got them all with two seconds to spare which is good for me cuz I hate math.

	mango:	Jun 7th, 2009 at 01:20 GMT	-3 points
	pretty easy. hey what time do you guys get to bed? i'm in bed at 8:00... and home by 11:00!

	tere:	Jun 11th, 2009 at 00:21 GMT	0 points
	Yay I did it!

	White:	Jun 17th, 2009 at 19:06 GMT	-2 points
	Did it in 31 seconds o/

	jimmyking211:	Jul 16th, 2009 at 00:34 GMT	1 point
	i need more time

	andrea:	Jul 31st, 2009 at 17:56 GMT	5 points
	Either give less time, or penalize wrong answers -- as it is it's too easy to get by guessing all the odd numbers not divisible by 5 or 3 (either of which can be recognized at a glance).

	Mxlexrd:	Aug 24th, 2009 at 15:18 GMT	2 points
	Curses - i needed 0.1 seconds more and i would have got all of them.

	fasttrack:	Oct 7th, 2009 at 20:53 GMT	1 point
	26/30 just guessing random numbers could have done it better if i didn't type in every single number

	edderson:	Nov 20th, 2009 at 23:22 GMT	1 point
	Definitely could have been more challenging.

	WyvernSabres:	Apr 1st, 2010 at 22:40 GMT	1 point
	18 seconds suffice to type 30 answers: it must be easy.

	staircase:	Apr 11th, 2010 at 02:26 GMT	3 points
	the curious case of the dog in the night time helps a little

	cheesemonster:	May 26th, 2010 at 21:52 GMT	1 point
	got 19. ran out of time.

	MarkG_VA:	Jul 5th, 2010 at 20:56 GMT	2 points
	This quiz would be much better if you were only allowed a certain number of attempts (like the digits of pi quiz). With that, I think it would be a great quiz to help clear the cobwebs off of your mental math skills.

	SeriuosUsurious:	Jul 8th, 2010 at 16:34 GMT	1 point
	Searched "prime numbers" and was very stoked to see you put a picture of a spiral next to the quiz name. Too bad it doesn't show up (at least on my computer) on the quiz page itself.

	1 IS ALSO A PRIME NUMBER!!!
