This game is made up of a large dome ( 10" diameter) shaped like a Gumball Machine. First you fill the outer part of dome with gum balls, then you insert a penny - which puts one of the gumballs into play. You then use all the skill you can to maneuver the gumball to the center hole- if you get it there.. it delivers the gum ball down the chute to you! The TV commercial jingle that was featured in the advertising for this game said : "You pay, you play, you chew away, and save pennies everyday".
