Petals on a Rose Game is a computer version of the famous riddle/puzzle game called Petals on a Rose. It is rumored that Bill Gates was stumped by it for two days. It's usually played with a group of friends and a set of 5 dice. The game master rolls the dice and tells everyone the answer. This computer version of the puzzle works similarly, only in this case the computer plays as the game master. There is no source included because that would give away the answer. The binaries were made as universal as possible.
