The "Star-Jet" pinball machine, released by Bally Manufacturing Co. in December 1963, is notable for being the first to feature a 3-ball multiball mechanism. This innovation, referred to at the time as the "Blast-Off extra balls feature," allowed players to experience multiple balls in play simultaneously, enhancing gameplay excitement. The game is a two-player, electro-mechanical machine equipped with two flippers, three pop bumpers, two passive bumpers, two slingshots, five standup targets, and two kick-out holes.
