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.

These early machines were entirely mechanical; pulling the heavy side lever actually stretched a physical spring that spun the reelsThe physical lever is why slot machines earned the famous nickname 'One-Armed Bandits'Fey's original three-reel design was so perfect that it remained the absolute industry standard for over seventy years
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.
