The Origin of Gomoku
TUTORZONE SUBJECT GUIDE · HOBBIES
Gomoku — also known as “Renju” or “Gomoku-bibe” — is a board game with simple rules but profound strategies, widely popular in East Asia, especially in China, Japan, and South Korea. This guide traces its ancient Chinese origins, its spread across the region, and the evolution of the rules that turned a folk pastime into an international competitive game.
Direct Answer：What is the origin of Gomoku?
Gomoku is a board game with simple rules and profound strategies, originating in ancient China and spreading across East Asia.
The Ancient Origins of Gomoku
The Beginnings in Ancient China
Gomoku originated in China. According to historical records, as early as the Spring and Autumn and Warring States periods (around the 5th century BC), China already had a prototype game similar to Gomoku.
People at the time used a simple board and black-and-white stones to play, and the winner was whoever formed a line first. This primitive form is considered the earliest version of Gomoku.
The Evolution of the Name
In ancient Chinese books, Gomoku was once called “Wudao” or “Wumuqi”.
“Gomoku” means five pieces connected in a line — whether straight, horizontal, or diagonal, connecting five wins the game. This simple, clear rule has been used to this day.
The Spread of Gomoku Across East Asia
Introduced to Japan
Through cultural exchange between the Tang dynasty and Japan, Gomoku was introduced to Japan between the 7th and 8th centuries.
In Japan, the game is called “Gomunai”.
Japan later developed more formal competition rules based on Gomoku, such as the “Renju rules”, which emphasise fairness and strategy, and even established a dedicated Renju Association.
Popularity in South Korea
In South Korea, Gomoku is also popular and is known as “Omok”.
South Korea has developed its own competition system and technical school, making Gomoku one of the most popular intellectual competitive games in the country.
The Evolution and Standardisation of the Rules
The Original Rules
The rules of traditional Gomoku are very simple: both players take turns placing pieces on the board, and the first player to connect five pieces in a straight, horizontal, or diagonal line wins.
The board is usually a 19×19 grid, though other sizes such as a 15×15 grid are also used.
The Birth of the Renju Rules
To prevent the first player from gaining too great an advantage, Japan established the “Renju” rules in the early 20th century.
Under Renju rules, the black player (who moves first) faces extra restrictions — such as the forbidden “three-three”, “four-four”, and “overline” moves (forming more than five connected pieces is a foul) — in order to balance the two players’ chances of winning.
Modern Development and Internationalisation
The Founding of the Renju International Federation (RIF)
In 1988, the Renju International Federation (RIF) was established with the aim of promoting Renju and Gomoku and standardising international competition rules.
The RIF regularly hosts the World Renju Championship and youth championships.
Gomoku and Video Games
With the development of technology, Gomoku quickly entered computer and mobile platforms, and various online Gomoku games and AI game programs have become popular around the world.
Platforms such as Yahoo Games, the KGS Renju Server, and Gomoku apps allow players around the world to play and connect at any time.
