Cool. 5 stars... congrats for an excellent teaser
I like, but lots of possible answers for this one.. hard to determine what you are looking for
Thank you both! It might be hard to figure out what you were looking for, but that's why the hint's there.
Pure Brilliance. The hint gave it away but that cannot detract from a puzzle of pure ingenuity
Got me in that I did not look at the hint beforehand. Without it, I was stumped and the only answer I cam up with was the the first number was the only one under 50. Good puzzle w/ the hint.
thanks soooooooo much you guys!
Very nice! By the way: do you like LIV Ullmann?
Oh! And what do you think about the '626' being the only number without an odd digit?
Sorry! I got a third one: '1009' is the only prime number.
great ideas Gerd! By the way, what is LIV Ullmann???
Liv Ullmann is a great actress (in my opinion). Maybe Liv Tyler is more known, but I really like Liv Ullmann. Liv is common first name in the scandinavian area, meaning the same as 'life'.-I wish you a nice day, cool_star--Gerd
WOW.... I got it right...
Go Rose!!!!!!!!
Okay, Gerd, have a great day to you too! and way to go rose_rox!
I thought 38, as it was the only number made entirely of circles or semi circles. There were no straight lines.
that's a very cool idea!!!!!!! i love it!
unless i messed up my math horrible, 1009 is the only one that does not have three as a factor.
i waas thinking "triumvirate" at the hint. thats probably a historical mess up on my part as well...
