This machine aimed to line up each of the three reels with the liberty bell symbol doing so would pay a jackpot of 10 coins, so at a single coin (5c) per spin, you would have the chance of winning back ten times your bet (50c jackpot).

This machine had just one pay line, with each reel featuring five symbols – some you would recognize today – spades, hearts, diamonds, a horseshoe, and a bell. They were featuring three spinning reels operated by a handle and a single slot to place a coin into.

The machine that Fey created was simple but complex in concept, and this machine was called the Liberty Bell. Modern slot machine games trace back to large and unique machines manufactured by an avid mechanic (and tinkerer) of the late 19th century, Charles Fey.
