Zingo

Zingo, manufactured by United Manufacturing Company in October 1951, is an example of a "bingo" pinball machine, a category of EM games popular in the 1950s that emphasized card-matching and hole-based scoring over flippers. Zingo's gameplay involves navigating five 1 1/16-inch steel balls through a playfield with 25 trap holes, aiming to complete winning combinations across three cards embedded in the layout.

The machine's console cabinet, similar to that used for United's 1951 game "A-B-C," measures 49 inches long overall, with a backbox 26 1/2 inches wide and 68 1/2 inches high, and a playing area 40 inches long and 22 inches wide. A single bell provides the game's sound effects.

Little is known about the designer or specific theme behind Zingo, and its bingo-style mechanics represent a distinct branch of pinball design from the more familiar flipper games of the same decade.
