Petals Around the Rose: Fraternity Register

That was fun. The solution stares you in the face: the best kind of puzzle.

Wow, that's pretty clever. Took me all of ten minutes, and ranting to friends, to figure it out, but... Wow. Silly kind of, but really tricky if you can't figure it out. Good job to everyone who figured it out!

I can't believe how simple this is, once one figures it out.

Took about 15 min.

It's the flash of certainty with which the answer arrives that I found so unexpected - A fairly average 15 - 20 minutes (I wasn't that sure when I started)

Very interesting little puzzle. I can't wait to torture math team with it.

hahaha, this was fun I'll add this to the list of way to make people hate me at parties

Wow, the name is important. Can't believe it took me so long

I came home very late last night from a party, exhausted, and stumbled onto this site from slashdot. It somehow kept me up for another /hour/, and I went to bed frustrated. When I woke, it was one of the first things I thought about (well, that and a dream about Claire Danes, weird), and I sprang out of bed with a new hypothesis that also turned out wrong. It was on the right track though, and I got it shortly after.

Nice brainteaser! Took me some very enjoyable fifteen minutes to figure it out. Now it's my turn to introduce a few more people to this game!

Yay! Got it.
