Dice
Overview
Dice (Chinese: 色子, shǎi zi; also known as 骰子, tóu zi) are small throwable objects with multiple resting positions, used as gambling devices or in tabletop games. They are typically cube-shaped, with each face marked with a number of dots (pips) from one to six. Traditional dice often have two colors, with one and four pips typically colored red while the others are black. Dice serve as one of the oldest forms of random number generation, with applications ranging from gambling to games of chance and statistical modeling.
History
The history of dice is remarkably ancient, with archaeological evidence suggesting their use dating back thousands of years. The earliest known dice excavated in the Middle East date to around 2400 BCE. In China, the earliest discovered dice were unearthed from a Warring States tomb in Qingzhou, Shandong Province, dating back over 2,300 years.
Early Chinese dice took various forms. During the Warring States and Qin-Han periods, fourteen-sided or eighteen-sided dice known as 'qióng' (焭) and long, stick-like 'zhù' (箸) were popular. These dice featured numbers or characters rather than the dot patterns common in later dice. The modern cubic form became standardized during the Eastern Jin Dynasty (317-420 CE), as evidenced by a porcelain dice discovered in an Eastern Jin tomb in Yuyao, Zhejiang.
A unique archaeological find in 2015 in Sichuan Province revealed a "top dice" (陀螺骰子) from the Han Dynasty. This artifact had a distinctive陀螺 (top-like) shape with a central six-sided body marked with one to six dots, suggesting it was used by spinning rather than rolling.

Cultural Significance
Dice have played significant roles in various cultures throughout history. In ancient China, dice were integral to numerous games of chance and strategy. The "Six Bo" (六博) game, popular during the Han Dynasty, used dice called 'zhù' to determine movement in board games. Similarly, games like 'Chūpú' (樗蒲) and 'Shuānglù' (双陆) incorporated dice as central elements.
A fascinating legend connects dice to the Tang Dynasty Emperor Xuanzong and his consort Yang Guifei. According to the story, the emperor was playing dice with Yang and needed two fours to win. As he rolled, he continuously called out "double four," and indeed, two fours appeared. Interpreting this as an auspicious sign, the emperor ordered the court painter Gao Lishi to paint all four pips red, and later, the corresponding one pip as well. This color scheme became standard and was widely adopted.
In Tibetan culture, dice games known as "Ba Ran" (八然) have a history of over two millennia. Originally used for divination in the indigenous Bon religion, dice games evolved into popular entertainment. By the 6th century CE, dice games were prevalent in the Tibetan Empire. In 2021, "dice throwing" was recognized as part of the Intangible Cultural Heritage of Ganzi Prefecture.
Modern Status
Today, dice remain ubiquitous in gaming and gambling contexts. Beyond traditional six-sided dice, modern gaming utilizes various polyhedral dice based on Platonic solids: tetrahedrons (4 sides), octahedrons (8 sides), dodecahedrons (12 sides), and icosahedrons (20 sides). These are particularly prominent in role-playing games like Dungeons & Dragons.
Dice have also attracted scientific interest as tools for studying probability and randomness. Italian mathematician Gerolamo Cardano analyzed dice probabilities in the 16th century, and French mathematicians Blaise Pascal and Pierre de Fermat corresponded about dice problems in the 17th century, laying foundations for probability theory.
Contemporary dice culture includes competitive stacking and manipulation. World records have been set for stacking dice in various configurations, such as the most dice stacked in a single column in one minute (40 dice by Ye Jiaxi in 2012) or the fastest time to stack 20 dice in a column (2.342 seconds by Zhang Ruixuan in 2023).
