Single Coin

The 1959 Bally Single Coin is an electro-mechanical bingo machine — a conversion of Bally's earlier 'Fun Way' or 'Lotta Fun' fitted with a replacement backglass. As its name suggests, this example was operator-modified so that all six bingo cards could be played for a single coin, rather than requiring separate coins per card.

Like other bingo machines of its era, Single Coin has no flippers; gameplay revolves around dropping balls into numbered holes to complete winning patterns across its cards. The machine awards free plays, though the running total is kept invisible until they are actually won, and each free play can then be redeemed for a single card. There are no extra balls, but the game will occasionally spot a center number at random on one of the cards, a feature operators could disable.

Few further details survive about Single Coin's specific artwork or design, but as a modified bingo conversion it offers a window into how operators customized Bally's popular bingo platforms to suit local payout regulations and player preferences in the late 1950s.
