I was wandering through the lust forest of mathematics blogs when I came upon Math at SBHS hosting of the Carnival of Maths. Here they featured a game called Petals Around the Rose. Without a good explanation on the page they sent you to, they did reference another article about the puzzle which is lovely.
The game involves rolling 5 dice and giving a numerical value to a given dice roll. Now I have only spent about 15 minutes give or take pondering the algorithm to this puzzle, and I have no idea what the method is. Apparently this puzzle is a fantastic test of intellegence. The intellegent folks take the longest. Give it a shot. If you can’t waste a quarter hour trying to solve this cute puzzle, then I’m very very impressed!
