In the A Song of Ice and Fire novels, Cyvasse is a board game which originated in Volantis, and spread through many of the other Free Cities. Due to Dorne's heavy trade contacts with the Free Cities, it recently spread there as well, starting in the first year of King Joffrey Baratheon's reign. It first arrived in the port at Planky Town, then spread up the Greenblood River valley. The game is all the rage in House Martell's court at Sunspear. It has not yet spread to the rest of the Seven Kingdoms, though soon after Tywin Lannister's death, the game is newly introduced to the capital, and Margaery Tyrell and her handmaidens are observed trying to learn the rules. The game is popular among both highborn and lowborn, and there are Cyvasse parlors in Volantis.
