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.
History of games
One of the oldest known ball games in history is the Mesoamerican ballgame ("Ōllamaliztli" in Nahuatl). "Ōllamaliztli" was played as far back as 1,400 BC and had important religious significance for the mesoamerican peoples such as the Maya and Aztec. The game evolved over time but the main goal was to keep a solid rubber ball in play by striking it with various parts of the body or with tools such as rackets. The game may have served as a proxy for warfare and also had a major religious function. Formal ballgames were held as ritual events, often featuring human sacrifice, though it was also played for leisure by children and even women.
