The earliest written references to the game come from the Zuo Zhuan, which described a man in 548 B.C.E. Other theories suggest that the game was derived from Chinese warlords and generals who used pieces of stone to map out attacking positions, or that Go equipment emerged from divination paraphernalia. Some legends trace the origin of the game to Chinese Emperor Yao (堯) (2337–2258 B.C.E.) who is said to have designed it for his son, Danzhu, to teach him discipline, concentration, and balance. This spelling is not widely used outside of events sponsored by the Ing Foundation. An alternative but uncommon spelling is Goe, proposed by Ing Chang-Ki, the late wealthy promoter of Go (particularly in Taiwan and the U.S.), for the same reason. In order to differentiate the game from the common English verb "go," the game is sometimes spelled with a capital G this convention, however, is not followed in most of the technical literature on the game. As a result, many Go concepts for which there is no ready English equivalent have become known elsewhere by their Japanese names.

The Japan Go Association has long played a leading role in spreading Go outside East Asia, publishing the English-language magazine Go Review in the 1960s, establishing Go Centers in the US and Europe, and often sending professional teachers to Western nations for extended periods. Because Japanese professionals taught the first Western players, the latter naturally used the Japanese name in early German-language and then English-language books and articles about the game. The game is most commonly known as 囲碁 (igo) in Japanese. The writings 棋/碁 are variants, as seen in the Chinese Kangxi dictionary. The Chinese name Weiqi (圍棋,围棋) roughly translates as " encirclement chess," " board game of surrounding," or " enclosing game." Its ancient Chinese name is 弈 (yì). The game is called Go in many languages this word originated from the Japanese pronunciation "go" of the Chinese characters 棋/碁 in Japanese the name is written 碁. Many Go players enjoy the complexity of the game because they feel it resembles the complexity of life. High-level players learn to interpret the shapes formed by the game pieces on the board and to develop their strategy according to their intuitive sense of the direction in which the game is flowing.
Through experience the Go player gains a deeper understanding of the game, which requires not only strategy but forward thinking and learning to take control of the game board by moving aggressively while protecting the position already achieved. It is especially popular with students because it develops their mathematical and strategic thinking. Originally played in China, Korea and Japan, the game began to gain popularity in the West during the twentieth century. Players must be aware of action in several areas of the board simultaneously, and the play evolves through numerous stages as players make their moves.
The size of the board and the number of pieces give rise to 2.1×10 170 possible positions, and it is said that the same game has never been played twice. The game ends and the score is counted when both players consecutively pass on a turn, indicating that neither side can increase its territory or reduce its opponent's the game can also end by resignation. The objective is to control a larger territory than the opponent by placing one's stones so they cannot be captured, but can capture any opposing stones played in one's territory. A stone is captured and removed if it is tightly surrounded by stones of the opposing color. Go is played by alternately placing black and white stones on the vacant intersections of a 19×19 rectilinear grid. The game is now popular throughout the world, especially in East Asia. It was played in ancient China before 200 B.C.E. Go or Igo in Japanese (囲碁), Weiqi in Chinese (圍棋, 围棋), and Baduk in Korean (바둑), is a strategic board game. The stones are lenticular and fit closely together when placed on adjacent intersections.
A traditional Go board is wooden, with black painted lines.
