To provide: a domination game using three-way deadlock pieces to solve such problem that a match cannot be carried out without covering by setting handicap for the difference in skill, when there is a large difference in skill in a conventional domination game; its board; and pieces.

In the domination game using three-way deadlock pieces, game players place at least three pieces which can move only forward and backward and become three-way deadlock facing each other while turning them face down on the board having at least three vertical lines of squares. A game in which a winner who wins by turning the piece face up advances the piece and widens the square area and a loser retreats the piece and reduces the square area is repeated. When even one piece among all pieces reaches an opponent's headquarter or a goal before opponent's turn or the match becomes invalid within a predetermined number of piece placing, the player who acquires a larger square area than the opponent wins the game.
