Also called Gomoko Narabe, in the Renju style. Or, 5 in a row. Black (the player who makes the first move) has long been known to have an advantage. Renju attempts to mitigate this imbalance with extra rules that aim to reduce black's first player advantage.
It is played on a 15×15 board, with the rules of three and three, four and four, and overlines applied to Black only.
