Gnip Gnop is a two-player table-top game in which the players try to get all 6 balls to the opponent's side first. The game begins with three balls and three levers per sides. The levers are for shooting balls to the other side. Between the two sides is a plastic barrier with the holes slightly larger than the balls. There are three pink balls and three green balls. The game is enclosed in clear plastic to keep the balls from flying out.
