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.

Charles Fey and the Invention of the Slot Machine

Before the Liberty Bell, gambling machines required a bartender to manually hand over a prize, like a free beer or a cigar.


The machine was a massive hit, and because Fey refused to sell his patent, competitors quickly began copying the three-reel design.

When gambling was temporarily banned, the machines were altered to dispense fruit-flavored chewing gum instead of cashThis era is exactly why we still use 'fruit symbols' like cherries and melons on modern slot machines todayThe famous 'BAR' symbol originally represented the corporate logo of the Bell-Fruit Gum Company
The Video and Digital Revolution

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.
