Gomoku has a rich history spanning thousands of years. The game is believed to have originated in ancient China over 2,000 years ago, where it was known as Wuzi Qi (五子棋), meaning "five-stone chess." From China, the game spread throughout East Asia, becoming deeply embedded in the cultural traditions of Japan, Korea, and beyond.
In Japan, the game became known as Gomoku Narabe (五目並べ), meaning "five pieces in a row," and gained popularity during the Meiji era. Japanese players developed sophisticated strategies and eventually created the Renju variant, which added rules to balance the first-player advantage.
In Korea, the game is called Omok (오목), which similarly translates to "five stones." Omok has been a beloved pastime for generations and remains one of the most popular casual board games in Korea today. It is commonly played on paper grids, in parks, in schools, and now online.
Gomoku gained international recognition in the 20th century and has been the subject of computer science research since the early days of artificial intelligence. In 1994, a program called "Gomoku Solver" proved that the first player can always win with perfect play on a standard 15x15 board under free-style rules, making it one of the first non-trivial board games to be computationally solved.
