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

The evolution of the slot machine is a fascinating journey that mirrors the massive technological leaps of the 20th century.

The Liberty Bell: The First True Slot Machine

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

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

• 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 Video and Digital Revolution

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.

Charles Fey's simple mechanical invention laid the foundation for a multi-billion dollar global entertainment empire.
