Backgammon

Backgammon was a board game at which the First Doctor was adept. In one 13th century session, he won from Kublai Khan: thirty-five elephants with ceremonial bridles, trappings, brocades and pavillions; four thousand white stallions; twenty-five tigers; the sacred tooth of Buddha; and the entire commerce of Burma for one year. Khan's wife disapproved of her husband's playing the game for stakes. She claimed that it aggravated his gout. (TV: Marco Polo)

In July of 1778, Shardlow lost a game of backgammon to the Celestial Toymaker at the Hellfire Club and was forced to become his slave. (PROSE: The Nightmare Fair/AUDIO: The Nightmare Fair)
