Once mechanical devices housed in physical casinos, Slot machines have come a long way from their humble beginnings. Today, online Slots are a cornerstone of the digital gaming landscape.
Having embraced technology, slot machines have evolved into sophisticated online games that range from simple Slots to more modern versions – like the Eye of Horus Jackpot King.
In this article, we’ll take a closer look at how Slots have transitioned from the mechanical into the digital realm. Read on to find out more.
The original slot machines
The journey of slot machines began in the late 19th century. Charles Fey, a San Francisco mechanic, designed what’s widely agreed to be the first true slot machine – ‘The Liberty Bell’ – in 1895.
This simple device had three reels, each with symbols including horseshoes, playing card suits, and bells along them. Players would simply pull a lever to spin the reels, hoping to align symbols for a payout.
The early slot machines were entirely mechanical, relying on gears and levers. They were known as the ‘one-arm bandit’ machines, due to the nature of the lever that would start the reels spinning when you pulled them.
As the years progressed, electrical components were introduced, allowing for more advanced designs in the machines. By the mid-20th century, slot machines had become a mainstay in land-based casinos almost everywhere.
Slots becoming more advanced
The 1960s marked a significant shift in slot technology, due to the advent of electromechanical machines. Bally, a gaming company, launched ‘Money Honey’ in 1964, which was the first fully electromechanical slot machine. This innovation eliminated the need for a lever, replacing it with buttons that you’d simply push to start the reels spinning.
The 1970s then saw the development of the first video Slots. In 1976, the Fortune Coin Company introduced a video-based slot machine that was designed using a modified Sony television. More advanced technology allowed for new and complex gameplay features, including bonus rounds, themed graphics, and multi-line betting options.
The introduction of the Internet
The next revolution came in the mid-1990s when the Internet made its debut. In 1994, Microgaming, a software company, launched the first online casino, featuring virtual slot games.
These early online Slots directly reflected the traditional casino machines, complete with basic graphics and sound effects. Despite their simplicity, though, they offered players the convenience of playing from anywhere with a reliable internet connection.
Online Slots quickly grew in popularity, spurring developers to innovate further.
Online Slots today
Today, online Slots are at the forefront of digital gaming innovation, since you have a vast range of games, cutting-edge technology, 3D graphics, and advanced features.
Also, mobile gaming has brought slots to smartphones and tablets, allowing players to push the button and spin the reels from their chosen device.
Another one of the most notable advancements is the use of random number generators (RNGs), which are software that ensure fairness and unpredictability in every spin – due to randomised algorithms.
You also have various slot themes, ranging from ancient mythology to blockbuster movies, so there’s something for every type of player.
