Up to four players compete to shoot white marbles up plastic ramps into a central square compartment. The box has nine red marbles in the center in a 3x3 grid. This grid is surrounded by three spaces on each of the four sides (forming a 4x4 grid with pillars for the corner spaces to hold the top of the compartment) for each player to shoot their marbles into. The red marbles in the center function as a shock transmitter to push other player's marbles from their spaces. The first player to get all their three marbles into the spaces wins.
