3-4-5

The 3-4-5, produced by United Manufacturing Company in June 1951, is an electro-mechanical bingo (payout) machine - a floor-model, console-cabinet game notable as the first United bingo game to use a conventional playfield layout rather than the flat, playfield-less designs common on earlier bingo machines.

Gameplay revolves around two cards that appear during play; players attempt to line up their shots with the values shown to win payouts, a format standard to the bingo pinball genre of the era.

Little detailed documentation survives about the specific design team behind the 3-4-5, but as United's first conventional-playfield bingo title, it holds a notable place in the lineage of the company's bingo machine output.
