You don't need to know anything about astrology to use Astrodice. They can be used for divination (asking questions), as a learning tool for astrology students, or just for fun. The leaflet enclosed with the dice explains the symbols and shows you how to interpret the results. With a little practice you'll recognize the symbols easily, and find that your intuition guides your understanding. There are many good astrological books that will further your understanding of the planets and their influences.
