I was never really was never impressed with the game of “Kerplunk”. I did own the game as a kid and played it often against my friends. I just never got into it.
It consists of a plastic tube, a number of plastic rods called straws and a number of marbles. The plastic tube stands upright on a base that contains four separate trays and the straws are passed through holes in the side of the tube to form a "web". The marbles are then placed in the top of the tube and held in place by the web.
At the start of play, the entire tube is rotated so that a hole in the base of the tube is aligned with the active player's tray. Players take turns removing a single straw from the cylinder while trying to minimize the number of marbles that fall through the tube and into their tray. Once a player has committed himself to a particular straw by touching it, they must remove it. The player who accumulates the fewest dropped marbles wins.
