From clunky cast-iron contraptions to highly advanced digital computers, the core appeal of pulling the lever has never changed.

Charles Fey and the Invention of the Slot Machine

Charles Fey, a Bavarian immigrant, revolutionized gambling by creating a machine that could automatically pay out winnings in coins.


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

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.


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