Charles Fey and the Invention of the Slot Machine

Charles Fey, a Bavarian immigrant, revolutionized gambling by creating a machine that could automatically pay out winnings in coins.


To win the ultimate jackpot of fifty cents, a player simply had to line up three Liberty Bell symbols across the single payline.

Cheaters frequently drilled small holes in the cast-iron cabinets to insert wires and manipulate the physical stopping mechanismsThe Liberty Bell was incredibly heavy, meaning it was usually placed permanently on the bartop of saloonsA single original Liberty Bell machine is still preserved today as a priceless historical artifact in Nevada
The Transition to Video Slots and RNG

Instead of physical reels, the Fortune Coin machine used a modified 19-inch Sony television to display digital, computer-generated symbols.


In the late 1990s, the internet boom allowed these advanced video games to transition seamlessly into the first online casinos.
