Did you know Sittman and Pitt of Brooklyn, New York develop a gambling machine in 1891[1] that was a precursor to the modern slot machine? It was based on poker and contained a total of 50 card faces.

It was played by inserting a nickel and pulling a lever which would spin the drums and the cards that they held.
