Slot machines are undeniably the most iconic symbol of any modern casino environment.

Yet, the high-tech video slots we enjoy today evolved from simple iron contraptions.

Charles Fey and the Liberty Bell

The history of slots officially began when Charles Fey introduced the Liberty Bell machine.

Fey's invention was beautifully simple: three mechanical reels and automatic coin payouts.

• Created in the late 1890s
• Replaced earlier poker machines
• Became an instant massive hit

The Introduction of Electricity

Until the mid-20th century, slots were completely dependent on gears and springs.

In 1963, Bally revolutionized the industry by releasing "Money Honey," the first electromechanical slot.

The Rise of Video and Online Slots

The true digital revolution occurred in 1976 with the invention of the first video slot.

Now, players can enjoy cinematic graphics and progressive jackpots from their mobile phones.
