No complete ancient rule text survives. Play is reconstructed from board layouts, marked squares and the partial instructions in late funerary compositions, and competing reconstructions disagree on movement and on how the marked squares functioned.
What would resolve this A papyrus or ostracon setting out the rules of play in full, from a securely dated context, or a securely dated board with an inscribed sequence complete enough to fix movement independently of the later funerary texts.
