Pong Hau K'i is an ancient Chinese tic-tac-toe-like game involving two players with two differently colored stones (say, red and blue). The players move their respective stones along a line to an adjacent empty space on a board consisting of five nodes and seven edges, illustrated above. The objective of the game is to trap the opponent so that no possible moves are available.
