King Rex

King Rex was an electro-mechanical pinball machine released by D. Gottlieb & Co. during the height of the EM era, featuring a prehistoric dinosaur theme that capitalized on the enduring public fascination with dinosaurs. The machine's artwork and theme represented a departure from the more common western, sport, or carnival themes of the era.

The game featured classic EM gameplay elements including pop bumpers, kick-out holes, and rollovers typical of early 1970s pinball design. The playfield likely included multiple lanes and targets that would have been standard for Gottlieb machines of this period. The scoring would have been displayed using mechanical wheels and chimes would have announced point accumulation, creating the distinctive soundtrack that made EM games so memorable.

While not one of Gottlieb's most famous titles, King Rex represents an important piece of pinball history from the final decade of the electro-mechanical era. The prehistoric theme would later be revisited by various manufacturers in the solid-state era, but King Rex stands as one of the earlier attempts to bring dinosaurs into the pinball arena.
