The objective is to clear the entire board except for a solitary peg in the center hole. At the beginning of the game, the marble in the center of the board is removed. You move by jumping a marble over an adjacent marble, much like in checkers, except that the moves must be horizontal or vertical only. The marble jumped over is removed. The aim of the game is to remove all the marbles except the last one, which should be left in the center of the board.
