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
How Technology Changed the Slot Machine Forever

The entire industry changed in 1976 when a Las Vegas company called Fortune Coin introduced the very first video slot machine.


However, the introduction of the Random Number Generator (RNG) microchip proved that the digital games were completely fair and random.
