Go (game)
Go is an abstract strategy board game for two players, in which the aim is to surround more territory than the opponent. The game was invented in China more than 2,500 years ago and is believed to be the oldest board game continuously played to the present day. 
A 2016 survey by the International Go Federation's 75 member nations found that there are over 46 million people worldwide who know how to play Go and over 20 million current players, the majority of whom live in East Asia.
Card game
The first playing cards appeared in the 9th century during Tang-dynasty China.
The first reference to the card game in world history dates no later than the 9th century, when the "Collection of Miscellanea at Duyang", written by Tang Dynasty writer Su E, described Princess (daughter of Emperor Yizong of Tang) playing the "leaf game" with members of the Wei clan (the family of the princess' husband) in 868 . The Song dynasty statesman and historian Ouyang Xiu has noted that paper playing cards arose in connection to an earlier development in the book format from scrolls to pages. During the Ming dynasty (1368–1644), characters from popular novels such as the "Water Margin" were widely featured on the faces of playing cards. A precise description of Chinese money playing cards (in four suits) survived from the 15th century. Mahjong tiles are a 19th-century invention based on three-suited money playing card decks, similar to the way in which Rummikub tiles were derived recently from modern Western playing cards.
