A-B-C

The A-B-C pinball machine, manufactured by United Manufacturing Company in March 1951, is a bingo-style electro-mechanical (EM) machine — a distinct category of pinball built around cards and pattern-matching rather than the flipper-and-ramp gameplay of standard pinball. As a Chicago-built EM title from the postwar bingo boom, it reflects the design conventions typical of that once-popular genre.

Notable features include a single pop bumper and a three-card layout, through which players complete patterns for scoring. The playfield is designed to resemble a roulette wheel, though it does not actually spin — a purely decorative touch. The machine is housed in a console cabinet, a common format for bingo-style games of the era, built to stand as furniture-style equipment rather than the upright cabinets of standard pinball.

Little is documented about A-B-C's designer or specific thematic details, which is typical for lesser-known titles from United Manufacturing's extensive bingo-game output. Even so, its roulette-inspired playfield and place within United's early-1950s catalog make it an interesting example of the bingo pinball subgenre for collectors and historians.
