Renju

Renju is a two-player abstract board game that belongs to the N-in-a-row family of games. It is a professional variant of traditional Gomoku that includes different restrictions for making the game fair. Renju was named by Japanese journalist Ruikou Kuroiwa in December 6, 1899, in a Japanese newspaper “Yorozu chouhou”. The name “renju” means “connected pearls” in Japanese. The game is played with black and white stones on a 15×15 gridded go board.

Why is Renju Popular?

Renju is a popular game in Japan and has a significant following worldwide. It is a game that requires strategic thinking and planning, making it a popular choice for those who enjoy board games that challenge the mind. Renju is also significant because it is a professional variant of Gomoku, which is a popular game in its own right.
