Go is a board game that two people compete to win or lose each other like Shogi.
And two players create their territory on the Go board.
They take territory on each other and compare the size of the final territories.
Once placed, a Go stone cannot be removed or moved unless it is completely surrounded by the opponent’s stone.
The area surrounded by your stone becomes the territory, and the player with the more territory wins.
Although the roots of Go are not clear, Go started in China from BC.
