The object of this game is to shoot at the balls, and try to arrange them in a  3, 4, or 5 in a line fashion.  Back in the late 50's, I played this game until my money ( $1.00 allowance) ran out at the PlayCenter arcade on Howard and Franklin.  Note the metal cigarette holder (circled) on the side of the machine.  These appeared on other earlier machines as well.
