Petals Around the Rose: Fraternity Register

Somebody linked me to this a while ago and I spent about five minutes puzzling over it, and then left it for a few hours. When I came back, I solved it by logic/maths in another five minutes, then worked out the actual pattern after that.

Since then I've showed it to numerous people. My grandfather followed exactly the same pattern as I did - ten minutes total, solved it by maths and then realised why it worked. My mother got it really quickly without maths. I've tried it on a lot of people who just gave up in frustration.

It's all about frame of mind, maybe even more than *how* your mind works. If you don't actually believe in your ability to solve stuff like this, you'll never get it.

(Plus, it helps to have the sort of view of maths that enables you to say "well, it says even numbers only, so somehow I need to get rid of the odd number on some of the dices...", even though it's really not a mathematical thought at all.)
