Petals Around The Rose is a game that is played with 5 dice. The point of the game is to figure out the answer of what the roll equals to. The person rolling the dice knows the answer, because he (or she) knows how to arrive at the answer. So, when the person rolls the 5 dice, the people playing have to say the answer before the person who rolls. But it's not a race to say the answer. The point is to see if the person playing can figure out how to arrive at the correct answer.
It took Bill Gates 90 minutes to figure out the technique to get the answer. Then he wrote a program for the game. I want to do that too in the near future, but I don't know enough C++ yet.
The only things the people playing are allowed to know are:
1. The name of the game is Petals Around The Rose.
2. An answer can only be a zero or an even number.
4. The answer to a particular throw.
Curiousity got the best of me and I looked up the answer after about 25 minutes.

But I was pretty close to figuring it out.

So how long did it take you to figure out the game?
