Weiqi, also known as Go, is an ancient board game that originated in China over 2,500 years ago. It is played on a grid of black and white stones, where players take turns placing their stones on the intersections. The objective is to control more territory on the board than the opponent by surrounding their stones. The game is known for its deep strategy and simple rules, making it accessible yet challenging. Weiqi can be played by two players and is popular in various countries, especially in East Asia. It has a rich cultural significance and is often associated with intellectual development and strategic thinking.
