I see from reading Boing Boing that the old "Petals Around the Rose" puzzle is making the rounds again. I have fond memories of being introduced to the game by a very good friend who loved this kind of thing. This puzzle is especially fun because many people have such a tendency to over-think it.

You can give it a try at Robert Borrett's site (and read a funny anecdote as to what happened when Bill Gates tried it). If I remember correctly, I managed to solve it in five rolls because my fourth roll was "no petals showing" which led me to ask a significant question about the game which my friend refused to answer (but the look on his face told me what I needed to know). On the fifth roll, I realized what was happening, and was inducted into the "Fraternity of Petals Around the Rose."

Just remember... once you've figured it out, you are forbidden to tell anybody the secret. All must come to the sacred knowledge for themselves!!
