Slot Revolution – The Role of Technology in Slot History

Tech Era’s Slot Revolution: The Wheel of Innovation

Slot machines are a staple in land-based and online casinos. Its unusual simplicity explains why it is the most popular casino game. Unlike others, slots come in various themes and formats and feature visually appealing graphics or sound effects. And now, with the integration of pop culture on online casino games, players can enjoy an even broader range of themes, making the gaming experience more immersive and enjoyable.

Innovative slot technology

Despite the popularity of slot machines in casinos, trends and innovations have shaped the technology landscape over the last decades. From the era of mechanical slots to its online variant, explore the tech era’s slot revolution below.

Mechanical Slot Machines – How It All Began

Slot machines have a fascinating history, from being called mechanical vending machines to becoming the most popular casino game. The first slot machine, popularly dubbed the “one-armed bandit,” had three rotating reels with various fruit symbols. As a result, people sometimes called it ‘fruit machines.’

Their earliest origin is traceable to the late 19th century. In 1895, Charles August Fey, a mechanic based in San Francisco, invented the first slot and called it the “Liberty Bell.” It features symbols like spades, diamonds, horseshoes, and the Liberty Bell.

Liberty Bell and the Prohibition Era

Although Charles Fey is credited with creating the first slot machine, there are arguments that Sittman and Pitt brought an earlier variant into the gaming world. Their version had 50 cards and five drums, costing players a nickel to play.

Nonetheless, Charles Fey’s automated slot machine received the first recognition. Next is Herbert Mills. Mills designed the first fruit machine with a bar symbol in collaboration with Charles Fey.

Slot machines were banned in the United States during the Prohibition Era of 1902. Still, Liberty Bell continued manufacturing. Due to the ban, people could no longer win cash prizes. In response, fruit machines took center stage. Instead of cash, players won candies and fruits. The new slot machines had fruit symbols, and players won corresponding flavours of gums and sweets that stopped in the reels.

Digital Age – Video Slots

The Money Honey Slot Machine became the first fully electronic slot in 1963. Its creator, Bally Technologies, designed a three-reel slot machine that allowed players to pull a mechanical lever. An electronic hopper ensures automatic coin payouts and electronic circuits govern the game.

Money Honey handled multiple coin denominations and coins per spin. As a result, it made the game more appealing and versatile. Unlike its mechanical predecessor, the new variant allows for a larger jackpot. Meanwhile, it set the ball rolling from purely mechanical slot machines to electronic and eventually computerized systems.

Video Slots

Despite the remarkable success of Money Honey, it was succeeded by video slots in the late 1970s. During this period, audio-video technology became the new rave, paving the way for video slots. Instead of reels, the machines used a digital display to show spinning reels.

Fortune Coin Company created Fortune Coin in 1976. It had the screen and display of a 9-inch Sony TV until IGT acquired the company. Around this time, the internet was coming to life. Likewise, random number technology, a computer algorithm, replaced physical spinning reels, ensuring more fairness in the game.

Online Slots – The Rise of Online Gaming 

The internet boom in the late 20th century paved the way for online casinos. Players accessed games from anywhere, courtesy of digital platforms. The technology offered a global reach, allowing players from different parts of the world to play.

The games featured high-quality graphics, immersive sound effects, and engaging animations. In all, players enjoyed a better gaming experience. Explore the timeline of events for the rise of online gaming below:
