4 Queens

Designer: Jim Patla Artist: Christian Marche

This single-player pinball machine features innovative "zipper flippers" that move together to prevent center drains when activated by skilled shots. Players attempt to light all four queens through a challenging A-B-C-D sequence. The Las Vegas casino theme reflects pinball's transition from underground entertainment to mainstream recreation during the early 1970s.

One of only 18 zipper flipper games produced by Bally, the 4 Queens represents the pinnacle of electro-mechanical engineering just before the solid-state revolution transformed arcade gaming.
