Gomoku: five stones in a row

Gomoku, also known as Five in a Row, is a strategic two-player board game. Players take turns placing their stones—typically black and white—on a grid, traditionally 19x19 or 15x15 in competitive play. The goal is to be the first to create an unbroken line of five stones in any direction: horizontal, vertical, or diagonal. Variations of the game exist with slight rule differences. Originating in ancient China over 2,000 years ago, Gomoku has gained global popularity and is now played in organized tournaments worldwide. Its simple rules and deep strategy make it a timeless classic.
