Extra Inning

Extra Inning, manufactured by Williams in 1962, is an electromechanical (EM) baseball-themed pinball machine featuring three illuminated red plastic ramps and a mechanical backbox animation of men running the bases. Its release tapped into the enduring popularity of baseball in the United States.

Gameplay centers on navigating the ball through the three ramps to score points, while the mechanical backbox animation brings the base-running action to life. The sound package is simple but effective, using two bells and a knocker to punctuate scoring events. The red plastic ramps, which illuminate from underneath, are a distinctive visual touch for a game of this era.

Little is documented about Extra Inning's designer or specific trivia surrounding its release. Still, as a single-player Williams EM baseball title from the early 1960s, it offers an interesting look at the sports themes and mechanical animation techniques used in pinball of that period.
