Gomoku is a strategic board game played between two opponents. Using a grid of 19x19 points (traditional) or 15x15 (competitive), players take turns placing their black or white stones. The goal is to create an unbroken line of five stones in a row�vertically, horizontally, or diagonally�before the opponent does. Variations exist, with minor rule differences influencing gameplay. Originating in China over 2,000 years ago, this classic pastime has gained global popularity and is now featured in organized tournaments. Its blend of simplicity and deep strategy continues to captivate players worldwide.
