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.

...abundant evidence may be marshalled to prove that this is the oldest outdoor game in existence. In the 22nd chapter of Isaiah is found the verse, "He will turn and toss thee like a ball." This allusion, slight as it may be, is sufficient unto the antiquary to indicate that some sort of game with a ball existed as early as 750 years before the Christian era, the epoch customarily assigned to the Book of Isaiah.
