From wikipedia:
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 19x19 intersections;[1] however, because once placed, pieces are not moved or removed from the board; gomoku may also be played as a paper and pencil game. This game is known in several countries under different names
This project is an implementation of Five-in-row game. It has two kinds of AI: very simple score-based, and an ok-ish AI that uses threat-space search (you can read about here), and two UIs: one for debugging, and one for Windows Store.
