Gomoku

Gomoku

Gomoku, also called Five in a Row, is an abstract strategy board game. It is traditionally played with Go pieces (black and white stones) on a Go board, using 15×15 of the 19×19 grid intersections.[1] Because pieces are not moved or removed from the board, FIR may also be played as a paper-and-pencil game. The game is known in several countries under different names.

Players alternate turns placing a stone of their color on an empty intersection. The winner is the first player to form an unbroken chain of five stones horizontally, vertically, or diagonally.
