One-armed bandits are undoubtedly the most popular fixtures in both land-based and online casinos. With exciting sounds and thrilling jackpots, they draw in countless gamblers around the globe. However, these gambling devices have a long and fascinating history going back more than 100 years.

The Original Slot Machine


The history starts around 1891 with a poker-based machine invented by two inventors named Sittman and Pitt. The contraption used five drums showing poker cards. A gambler would put in a coin and pull a lever to spin the drums. Rewards were not automatic; instead of coins, lucky players got free drinks or cigars depending on their poker hand.

Charles Fey's Invention


Shortly after, towards the turn of the century, a mechanic named Charles Fey built the original automatic payout machine. Named the Liberty Bell, this machine had 3 distinct reels containing simple icons: hearts, spades, diamonds, horseshoes, and the bell.
