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 Liberty Bell: The First True Slot Machine
The story begins in 1894 in San Francisco, when a mechanic named Charles Fey invented a machine called the Liberty Bell.
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 cash
- This era is exactly why we still use ‘fruit symbols’ like cherries and melons on modern slot machines today
- The famous ‘BAR’ symbol originally represented the corporate logo of the Bell-Fruit Gum Company
The Transition to Video Slots and RNG
Initially, players were highly suspicious of video slots because they could not physically see the reels spinning and stopping.
However, the introduction of the Random Number Generator (RNG) microchip proved that the digital games were completely fair and random.

| Megabucks (1986) | First linked progressive network | Created the first multi-million dollar slot jackpots |
| Online Slots (1996) | Transition to the internet | Allowed players to gamble from their home computers |
Charles Fey’s simple mechanical invention laid the foundation for a multi-billion dollar global entertainment empire.
