A Brief History of the Casino Slot Machine

Today, slot machines generate over 70% of all casino revenue worldwide, dominating the floors with massive screens and loud music.

Tracing the history of these machines reveals exactly how the modern gambling industry was built.

The Mechanical Era: The Birth of the Liberty Bell

The story begins in 1894 in San Francisco, when a mechanic named Charles Fey invented a machine called the Liberty Bell.

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 mechanisms
The Liberty Bell was incredibly heavy, meaning it was usually placed permanently on the bartop of saloons
A single original Liberty Bell machine is still preserved today as a priceless historical artifact in Nevada

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

Video slots allowed developers to break free from the physical limitations of metal reels, adding multiple paylines and complex bonus rounds.
