Go is a kind of board game originated from China with only black and white pieces. This design changes the chess pieces into an embedded three-sided rotating body. The three sides are black, white and the color of chessboard. Change the color by rotating with your fingers. Moreover, the metal block is embedded in the middle of black and white. At the end of the game, swing the chessboard hard to make the metal block face down (the color side of the chessboard faces up), quickly recover and start the next game without clearing up one by one.
