Bally’s 1968 release, Op-Pop-Pop, stands as a vibrant, kaleidoscopic relic of the late sixties, capturing the era’s psychedelic art movement through the mechanical ingenuity of designer Ted Zale and artist Christian Marche. Unlike the sprawling, multi-level machines that would dominate later decades, this single-player EM is defined by its compact, high-energy layout and the inclusion of Bally’s signature “Zipper Flippers.” These spring-loaded mechanisms, which snap together to eliminate the center gap, transform the game from a standard defensive posture into an aggressive, point-chasing experience that demands precision and quick reflexes.
The playfield is a dense forest of eleven rollover buttons and five distinct mushroom bumpers, creating a chaotic, unpredictable pinball path that reflects the title’s name. A unique bagatelle-style feature in the upper playfield adds a layer of classic, gravity-fed skill, while the left drop lane and strategic kick-out hole keep the pace frantic. With only 1,050 units produced, Op-Pop-Pop is a rare find for collectors who appreciate the tactile, rhythmic satisfaction of reel-based scoring and the frantic, “popping” action of a well-tuned EM. It remains a masterclass in how mid-century designers could maximize the potential of limited space, turning a simple playfield into a swirling, psychedelic gauntlet.
