Found some interesting stuff on the game they were playing... What looked like some form of Senet...
Senet may be the oldest board game in the world. It has been found in Predynastic and First Dynasty burials of Egypt,[2] circa 3500 BC and 3100 BC respectively. Senet is also featured in a painting from the tomb of Merknera (3300–2700 BC) (see external links below). Another painting of this ancient game is from the Third Dynasty tomb of Hesy (c. 2686–2613 BC). It is also depicted in a painting in the tomb of Rashepes (c. 2500 BC).
By the time of the New Kingdom in Egypt (1567–1085 BC), it had become a kind of talisman for the journey of the dead. Because of the element of luck in the game and the Egyptian belief in determinism, it was believed that a successful player was under the protection of the major gods of the national pantheon: Ra, Thoth, and sometimes Osiris.
