Gomoku is an abstract strategy board game. Also called Gobang or Five in a Row, it is traditionally played with Go pieces(black and white stones) on a go board. The rule is black plays first if white did not just win, and plays alternate in placing a stone of their color on an empty space. The winner is the first player to get an unbroken row of five stones horizontally, vertically, or diagonally.
