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.
Chinese playing cards
Playing cards () were most likely invented in China during the Southern Song dynasty (1127–1279). They were certainly in existence by the Mongol Yuan dynasty (1271-1368). Chinese use the word "pái" (), meaning "plaque", to refer to both playing cards and tiles. Many early sources are ambiguous if they don't specifically refer to paper "pái" (cards) or bone "pái" (tiles). In terms of game play, there is no difference; both serve to hide one face from the other players with identical backs. Card games are examples of imperfect information games as opposed to Chess or Go.
