They’re among the most widely played casino games today, both in land-based venues and on digital casino platforms, and they have a mix of straightforward gameplay and wide theme variety. We’re, of course, talking about Slots.
But where did this highly popular online casino game come from, and how did it make the leap to digital platforms?
The origins of online Slots traces back to mechanical devices from over a century ago, and they’ve come a long way since then, with new features, rules, and symbols along the reels. Understanding where online Slots come from means looking at a timeline of both technological evolution and changes in gambling regulation.
In this article, we’ll outline the key milestones that brought slot machines from physical lever-pulling games to the digital formats found on modern casino sites today.
The Mechanical Beginnings (1890s)
The story of Slots begins in the late 19th century.
In 1895, Charles Fey, a car mechanic from San Francisco, created what’s considered to be the first true slot machine. His version, the ‘Liberty Bell’, featured three spinning reels and five symbols, which were horseshoes, diamonds, spades, hearts, and a cracked Liberty Bell.
You would need to pull a mechanical lever that spun the reels around, and matching three Liberty Bells triggered the highest payout.
As these machines grew in popularity, they developed the nickname “one-armed bandits” – due to the lever-pulling motion.
Electromechanical Advancements (1960s)
While the basic concept of slot machines remained intact for decades, significant innovations began to take place in the 1960s.
In 1963, Bally Technologies released the ‘Money Honey’, the first electromechanical slot machine. Instead of cogs and springs to spin the reels, this machine introduced electrically powered reels and a bottomless hopper, which allowed for automatic payouts. This paved the way for more complex game mechanics and set the stage for further digital development to come.
The Rise of Video Slots (1970s–1980s)
The next major leap came in 1976 when a company called Fortune Coin developed the first video slot machine.
These machines displayed the reels on a digital screen instead of using physical reels. After receiving regulatory approval, video Slots began to spread across land-based casino venues, offering a new level of flexibility in terms of graphics, symbols, and game design.
The Birth of Online Slots (mid-1990s)
With the rise of the internet, the first online casinos appeared in 1994. These early online Slots replicated the style of traditional machines, except they are accessible through computer devices with a stable internet connection.
The internet’s rapid expansion and the increasing availability of computers allowed online Slots to grow in popularity.
Development of Features and Themes (2000s Onwards)
As internet speeds and computer processing power improved in the 2000s, online slots have only improved in features and designs.
Games now incorporate more detailed graphics, themed game worlds, and multi-line formats. Many games offer bonus rounds, wild symbols, scatter symbols, and other features that help keep gameplay fresh and innovative for players.
Slots have also become available on mobile devices, and many developers create titles specifically optimised for smartphones and tablets, reflecting changing player preferences.

From the Liberty Bell to mobile online platforms, the history of Slots is marked by many technological innovations and changes.
However, with each stage in their evolution — mechanical, electromechanical, video, and online — the core aim has remained the same: spin the reels and land matching combinations.
