Gnip Gnop

Gnip Gnop was made by Parker Brothers in 1971. It was a two-player table-top game in which the players try get all 6 balls to the opponent's side first. The game began with three balls and three levers per sides. The levers were for shooting balls to the other side. Between the two sides was a plastic barrier with the holes slightly larger than the balls. There were three pink balls and three green balls. The game was enclosed in clear plastic to keep the balls from flying out.

The name comes from "ping pong" spelled backwards.
