Description
20 Squares appears for the first time at the beginning of the second millennium BCE. It seems to be derived originally from the the Royal Game of Ur, becoming particularly popular in Iran, the Levant, Egypt, and Cyprus in addition to Mesopotamia during the Late Bronze Age (1700–1050 BCE), and continued being played in Mesopotamia into the Seleucid period, at least until the second century BCE. It may have been called É Er-bé-et-ta, "Room Four," which is mentioned in cuneiform tablets.
Rules
