The name of the game is important. The computer will roll five dice and ask you to guess the score for the roll. The score will always be zero or an even number. Your mission is to work out how the computer calculates the score.
Figure it out and you can join the Fraternity of Petals Around the Rose.
A Flash version is available as well.

So you didn’t mention if you are a member of the Fraternity. Let’s see… If you are, you will know the answer to this roll of the “dice”:
6 4 3 1 6
2 – I knew about this puzzle years ago, and at the time I probably had to look up the solution.
