"OBJECT: BEAT YOUR OPPONENTS OVER THE WALL"
"A SKILL GAME OF COOPERATION"
A transparent plastic hexagonal tower about 12" high with holes in the sides is separated into two compartments by a semi-transparent plastic dividing wall. Each player drops three plastic balls of their respective color into the closest section; the balls have small holes on their surfaces. Each player is given two small plastic spear-like devices which are used to maneuver the balls over the dividing wall into the opponent's section.
The first person to get their three balls over the dividing wall wins the round. The first person to win three rounds wins the game.
The rules also suggest that teams of two can compete, with each player given one plastic spear.
