Rule

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 with 15x15 intersections.

Black plays first if white did not just win, and players alternate in placing a stone of their color on an empty intersection. The winner is the first player to get an unbroken row of five stones horizontally, vertically, or diagonally.

Enable "Sente" to make the first move against Computer. The player who makes the first move was long known to have a big advantage. Disable it to let computer move first will be much more harder.
