ABSTRACT:
The invention uses dice-like polyhedral solids (30) (32) (44) to generate randomly the lines of I Ching hexagrams. It produces outcomes according to a traditional and theoretically important frequency distribution. That distribution requires that the four line types of the I Ching system (36) (42) (38) (40) occur in a relative frequency of 1:3:5:7. The invention accomplishes this through a specific arrangement of indicia (26) (28) (46) (48) (50) on the dice. The dice are so constructed and the indicia so disposed that any roll shall yield one of the numerical results 6, 7, 8, or 9. These values correlate with the four line types, and the statistical likelihood of each possible result conforms to the theoretically ideal frequency distribution of all such results. Three dice are used in the preferred embodiment, each of a rounded, substantially tetrahedral form.
