Bingo

Bingo, manufactured by Keeney and Sons in September 1931, is an early example of pinball's mechanical origins, released around the same time as other pioneering counter-top amusement games of the era. As a Pure Mechanical (PM) machine, it relies solely on physical mechanisms -- gravity, springs, and plunger action -- to move the ball, predating the invention of the flipper (which would not appear until 1947) by more than a decade.

As a table-top/counter game, Bingo was designed for compact placement in stores, bars, and amusement parlors rather than as a standalone cabinet game. Specific details of its playfield layout and scoring features are not well documented, but its design would have been simple and functional in keeping with other machines of its era.

Little is known about Bingo's designer or intended theme, and its rarity and early production date make it a piece of interest for historians tracing pinball's earliest years -- a period defined by simple mechanical ingenuity rather than the flippers and elaborate features that would come to define the game decades later.
