An inflated balloon is positioned in a chamber having a top with a hole formed therethrough. An elastic partition is supported above the chamber and has a plurality of needles affixed thereto and extending perpendicularly therefrom into the hole. A partition with a plurality of mutually spaced holes formed therethrough is positioned above the elastic partition. A plurality of marbles are dropped by the players through the holes of the partition having the holes therethrough so that when a sufficient number of marbles rest on the elastic partition, the weight thereon stretches the center area of the elastic partition downward sufficiently to force a needle thereof through the hole in the top of the chamber into the balloon thereby bursting the balloon.
