Go Classic

Go is an abstract strategy board game for two players in which the aim is to capture more territory than the opponent by fencing off empty space. 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.
