Mehen — "the coiled one" — is the ancient Egyptian board game played on a spiral track shaped like the body of the benevolent snake god who wraps his coils around the solar barque of Ra, shielding the sun from the chaos serpent Apophis during the perilous nightly journey through the Duat. Emerging from the Predynastic Naqada II period (c. 3600–3200 BCE), Mehen is the oldest known multiplayer game in the world, engineered for up to six players. The board's spiral path, carved in limestone or faience, represented the coiled body of the deity; the small marble pieces represented pharaohs navigating toward the divine centre; the oversized lion and lioness figurines — too large to fit on the track — functioned as predatory forces controlled by opposing players. Recent scholarship by James F. R. Masters has reconstructed the game's mechanics as a system of psychological brinkmanship: movement was governed not by dice but by a marble-guessing bluffing mechanic, and lions were unleashed through successful guesses, paralysing opponents until defeated in further rounds of deduction. The game vanished from the Egyptian archaeological record around 2300 BCE, but its theological identity survived: by the New Kingdom, Mehen had become the invisible divine opponent in afterlife games of Senet, hailed as "MEHEN the noble, the lord of the Senet." The Academy hosts Mehen in the Heart School because its central exercise was devotional: the board was a simulacrum of the underworld, and to play was to rehearse the soul's passage toward eternal rebirth.
