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
In Ancient Greece and in the Roman Empire, popular games included ball games (Episkyros, Harpastum, Expulsim Ludere - a kind of handball), dice games (Tesserae), knucklebones, Bear games, Tic-tac-toe (Terni Lapilli), Nine Men's Morris (mola) and various types of board games similar to checkers. Both Plato and Homer mention board games called 'petteia' (games played with pessoi', i.e. 'pieces' or 'men'). According to Plato, they are all Egyptian in origin. The name 'petteia' seems to be a generic term for board game and refers to various games. One such game was called 'poleis' (city states) and was a game of battle on a checkered board.
