What is Gomoku?
Gomoku is a five-in-a-row strategy game for the browser: two sides fill a 15×15 grid one mark at a time, and whoever first lines up five X's or five O's across, down or on a slant takes the game. Play it against a computer set to Easy, Medium or Hard, where Hard hunts for forced wins built from fours, or pass one phone between two people. For a stricter game, the blocked-ends rule from Vietnamese caro voids any five hemmed in by the opponent's marks at both ends.
