Ashtapada is a term referring to a board game that predates Chess in India. It is widely believed that the 8x8 Ashtapada board, which is marked in certain places, was appropriated and used for Chaturanga, since many Chaturanga boards in India maintain the Ashtapada markings, though they are meaningless for Chess. In the Ashtapabada of Balabharata (thirteenth century), a dice game is described as being played on the Ashtapada, with dice determining the movement of pieces on the board.
