Dice

• 1. Ancient Origins And Archaeology

  ›

  Archaeologists uncovered a set of dice at the Burnt City in south-eastern Iran, dating between 2800 and 2500 BCE. These artifacts represent some of the oldest known examples of throwable objects with marked sides used for generating random values. Excavations at Mohenjo-daro in the Indus Valley civilization revealed terracotta dice from 2500 to 1900 BCE. One specific die found there had opposite sides that added up to seven, matching modern standards. Bone dice discovered at Skara Brae in Scotland date back to 3100, 2400 BCE. Ancient Egyptian games like senet utilized flat two-sided throwsticks before 3000 BCE. The Rigveda and other ancient Indian texts mention games involving these early forms of chance devices.

• 2. Etymology And Gambling Culture

  ›

  The word die derives from Old French dé and Latin datum meaning something which is given or played. Professional gamblers still use obsolete terms like ace, deuce, trey, cater, cinque, and sice to designate different sides of the dice. Ace comes from the Latin as meaning a unit while the others originate from 2 to 6 in Old French. The term snake eyes refers to rolling one pip on each die and traces its use back to 1919 according to the Online Etymology Dictionary. US gamblers call a roll of six pips on each die boxcars or midnight because the pair resembles freight train cars. Romans called dicing aleam ludere despite gambling being illegal during their era. Two sizes existed: large tali inscribed with one three four and six pips and smaller tesserae numbered one to six.

• 3. Manufacturing And Precision Engineering

  ›

  Non-precision dice are manufactured via plastic injection molding using polymethyl methacrylate often made opaque or transparent through added pigments. The coloring process involves submerging the entire die in paint then polishing it via tumble finishing similar to rock polishing. Precision casino dice differ significantly by being made from extruded cellulose acetate bars sawed to ensure square faces. These high-quality dice feature flush markings drilled deep and filled with opaque paint matching the density of cellulose. New Jersey regulations specify maximum die size at 19 millimeters except for pai gow which ranges from 15 to 17 millimeters. Casinos require serial numbers and logos on every precision die to discourage substitution cheating. Transparency allows inspectors to detect internal weights that could bias results against fair play.

• 4. Polyhedral Shapes And Geometry

  ›

  Modern polyhedral dice sets emerged around the end of the 1960s when wargame players adopted non-cubical shapes. Five Platonic solids form standard sets including tetrahedron octahedron dodecahedron and icosahedron alongside a cube. A ten-sided pentagonal trapezohedron features kite-shaped faces meeting at sharp corners where five kites converge. Tetrahedral dice lack an upward-facing side so players read values near vertices or along base edges instead. Opposite faces on most dice add up to one more than the total number of sides though this fails for four-sided dice. The zocchihedron serves as a true hundred-sided alternative despite lacking consistent fairness across all results. Some twenty-sided dice arrange adjacent integers together to help users track countdown health points in games.

• 5. Modern Gaming Applications

  ›

  Dungeons & Dragons largely popularized polyhedral dice usage within role-playing games starting in the late twentieth century. Standard role-playing sets include seven dice: d4 d6 d8 d12 d20 plus two d10s labeled zero to nine and zero to ninety. Percentile systems combine these two decahedral dice to generate random numbers from zero to ninety-nine. Games like Castles of Burgundy treat each die value equally without higher numbers being inherently better. Quarriors allows different sides to grant resources or actions rather than just movement distances. Monopoly uses 2d6 rolls to determine how far pieces move along its board tracks. Axis & Allies inverted traditional systems by making lower values more potent for conflict resolution.

• 6. Cleromancy And Divination Practices

  ›

  Tibetan Buddhists employ pairs of common dice for cleromancy practices aimed at fortune-telling and religious rituals. Pythagoreans likely used Platonic solids as dice referring to them as the dice of the gods while seeking universal understanding through geometry. Astrological dice consist of three twelve-sided units representing planets zodiac signs and houses respectively. Magic 8 Ball answers derive from specialized icosahedron dice providing yes-or-no responses to questions. These divination methods rely on probability distributions where rolling single six-sided dice yields uniform outcomes across faces one through six. Summing multiple dice shifts probabilities toward certain totals like seven becoming more likely than extremes like two or twelve.

• 7. Cryptographic Randomness Generation

  ›

  The Electronic Frontier Foundation describes using five dice rolls to generate secure passphrases via Diceware methodology. Players repeatedly roll five dice selecting corresponding words from pre-generated lists to create memorable yet strong passwords. Physical dice serve as hardware random number generators introducing uncertainty through minor hand movements during throws. This approach produces uniform distributions where each face from one to six has equal chance appearing initially. Combining results creates specific probability distributions fundamental to modern cryptography applications. Such systems allow users to generate random numbers without relying solely on digital algorithms that might be compromised.
