Humanity's first dice were literally sheep ankle bones, and casinos owe them royalties.
means A game played by tossing and catching small bones (originally animal ankle bones, later carved imitations), an ancestor of modern dice and jacks.
from From 'knuckle' + 'bones' — the actual astragalus, the small knobby ankle bone of sheep or goats, which rolls to rest on one of four distinct sides. Ancient peoples across Greece, Rome, and beyond used these bones for games of chance and fortune-telling long before anyone carved the first cube die; the Greeks called the game astragaloi, the Romans tali. The bones' irregular, side-biased shape actually made them poor random generators compared to true dice, but their ubiquity (every butchered animal produced a fresh set) kept them in play for centuries, surviving today as the children's game of jacks.
