Zipper Flippers

Zipper Flippers are a vintage pinball feature where the flippers physically move together or apart to close or open the shot gap, creating dynamic shot-making and unique rule interactions that define a game's flow—an innovation popularized on mid‑century Bally machines. Invented by Ted Zale and first used on Bally titles like Bazaar, zipper flippers are prized by collectors and players for adding tactile excitement and strategic depth to classic machines. This tag highlights two rare zipper‑flipper games—RVk8 Doozie / Daffie and 42XZ Student Prince—making it a must‑see category for enthusiasts seeking standout vintage playfield mechanics and nostalgic Bally‑era flair.
