Each player has 15 marbles. Decide who goes first. Taking turns, each player places one marble on the playing board. When there are four marbles forming a square, a player may move from that level to an upper level providing his marble is adjacent to that square. The player that can place his adjacent marbles from the lower level to the upper level gains the advantage rather than to use his reserve marbles in the outer ring. The lower level must be filled before one can start stacking marbles on the second layer from his reserve marbles in the ring. The winner makes the final play. You’ll love the strategy involved in this game.
