In this game the players build a pyramid of glass marbles. Aim is to place the last marble on top of the pyramid. Besides placing a new marble of his color on the board, a player can move one of his marbles already on the board by raising it one or two levels. Or a player can take back two marbles from the board by making a square using four of his own marbles. This way a dynamic game is going on with a rising and shrinking pyramid.
