10-sided dice
Ten-sided dice are often used in role-playing games to get random decimal numbers, such as percentages. Such a die will have 10 kite-shaped faces. Opposite sides on such a die total nine.
10-sided die
Each face has two long sides and two short sides. The five odd-numbered faces meet at the common vertex of their long sides. The five even-numbered faces meet at the common vertex of their long sides.
There seems to be a standard configuration for the numbers on 10-sided dice. If one holds such a die between one's fingers at two of the vertices such that the even numbers are on top, and reads the numbers from left to right in a zigzag pattern, the sequence obtained is 0, 7, 4, 1, 6, 9, 2, 5, 8, 3, and back to 0. (In this position, odd numbers appear upside-down.)
These dice are often sold in pairs. One die will be marked by tens from 00 through 90, and the other will have units from 0 to 9. The use of these markings is obvious; however, in practice, two dice of different colours may prove easier to read.
