Introduction Notakto is a misere 3-in-a-row game for two players. It's played on the squares of a finite number of initially empty 3x3 boards. All pieces are exactly the same and are shared by both players. Definitions A board is dead if it contains at least one set of three stones in a straight orthogonal or diagonal line. A board that is not dead is alive. Play On their turn, a player must place a piece on an empty square of a living board. When all boards are dead, the player who made the last placement loses.
