Kerplunk was made by Ideal Toys in 1967. Players load the tower with 30 sticks to create a ‘nest’ then place 40 marbles on top of the nest. Players take turns in carefully removing the sticks to prevent any marbles from falling. Fallen marbles accumulate in designated player trays at the base of the tower. The winner is the player with the least amount of fallen marbles at the end of the game.
