Here’s an interesting page I stumbled across earlier – Bill Gates and Petals Around the Rose. This page describes a dice game that people having been playing since at least the 70’s. It’s a fun little mental exercise.
First, you roll five six-sided dice (5d6 for the hardcore D&Ders), then you guess the answer. There are only two rules:
- The name of the game is Petals Around the Rose, the name is significant.
- Every answer is zero or an even number.
I did a little Googling and found a Flash version of Petals Around the Rose. With this you should be able to play the game long enough to figure it out.
It took me about 30 minutes plus a page of graph paper full of notes to finally get it.
Just be careful if you decide to do your own search, some sites give away the secret. I wouldn’t want to have to give anyone a zero on this quiz for cheating.
