In this clever kids game, players try to get four marbles in a row by dropping them into holes at the top of a vertical tray much like dropping checkers in Connect Four. This tray, however, is filled with moving levers that shift as the marble drops through them. The marbles then land in a lower tray that is slotted to hold rows of marbles. This lower tray is where you need to align four in a row (vertically, horizontally, or diagonally) to win. So players may drop marbles tactically - to make an alignment, or strategically - to shift the levers for a future drop and/or block an opponent's move.
