Illat Kalbī: The Royal Game of Ur

This package provides code for playing the Early Dynastic Mesopotamian game 𒆜𒆳 𒌨𒂠𒈨𒌍 or illat kalbī -- the pack of dogs. These days, however, it is known more commonly as Twenty Squares or the Royal Game of Ur. The game’s rules were discovered and translated by Irving Finkel; the gameplay itself was solved by Joseph Heled.
