History of slot games

The iconic company behind the invention of the slot game is Liberty Bell, who funded the original inventor of what was then called the poker machine. In the late 19th century, Charles Fey’s invention was being tweaked and worked on constantly, quickly becoming popular in bars across San Francisco where Liberty Bell was based. The just a very simple mechanism that used playing card symbols was the icons on the reels, prizes were not the big amounts of cash that we can see online today. Rather, players could exchange their wins in at the bar for free drinks or cigars. A very different time indeed. Yet, Liberty Bell’s influence on the slot game world is still very much felt today as in traditional fruit machines, the bell symbol will regularly appear and this was introduced by Liberty Bell themselves, you used the bell as their logo. Once the slot machine progressed into an electronic game, it was lining the halls of Las Vegas casinos in the 1950s and 1960s, creating huge crowds of avid players than many people dubbed the one arm bandits, thanks to the way that players must pull a lever with one arm to play. By this point, the slot machine was a true sensation and it’s popularity rose and rose as it became a video game experience rather than relying on machinery and mechanical reels.

The first online slot games

The first online slot games emerged in the technologically influential 1990s and were initially a really simple way to gamble online. However, online gambling as a whole was a very different medium back then and even the notion of gambling, from your own home on a computer, was a marvel and a novelty. The games relied on very basic coding and were nothing like the online, 3D spectacles that we so regularly see online today. Yet, over time, the medium evolved and evolved and with greater technology came even better online slot games. Now, the smartphone is the latest invention to greatly impact the slot game as most online gamblers take part in online slot games via their handheld device. The new technology has created new possibilities once never dreamed of for this format and now it is very rare that a new online slot game is not made readily available and fully functional for the smartphone device. The rise of the smartphone has very much aligned with the rise of the online slot game. As the amount of smartphone users has increased so has the number of people gambling online and slot games have surely benefited from this.
