Slot machines have come a long way since they were first introduced in the late 19th century. From massive one-armed bandits set in salons to automatic land-based machines in casino establishments, slot machines have kept up with technology to become what they are now. 

Today, active slot players prefer convenience over the casino atmosphere, which is why online slot machines have become increasingly popular. As a result, many players have started to wonder about the basic configurations behind slot machine technology.

Even when discussing games of chance, players still wonder about the possibility of beating the odds. While engaging in free online slot games is fun in its own right, it’s challenging to get rid of that innate desire to beat the odds and come out as a winner.

Luckily, beating the odds is possible with the majority of casino games, including online slots. On top of that, there are a couple of different methods that could help you pull such a feat.

So, let’s find out more about the technology behind online slot machines.

Random Number Generators

Slots are games of chance. As such, they rely on Random Number Generators (RNGs) — algorithms that use unpredictability to create a random set of numbers or symbols. RNGs are implemented to graphics and other elements of slot machines to generate a different, random result with every spin of the reels.

All online slot machines that want to promote fair gameplay use RNGs, as these algorithms lack any predictable bias and specifically avoid repeating patterns. So, thanks to the RNGs, which have been digitally introduced into slot games, the game outcome depends only on your luck.

Coding and Design

All online casino slots exist thanks to coding wizards that use numerous platforms to develop slot games for both online and mobile use. With every upgrade and tweak, online slot games take a new form, which might not even be noticed at first glance. One game can be programmed with one or more programming languages, such as JavaScript, C, C++, Python, and others.

When it comes to design, fruit images are not the only desirable symbols on slot machines. Nowadays, players want to see more engaging and socially relevant symbols when playing online slots. In most cases, developers use tools like Photoshop, Maya, and JavaScript to design new graphics.

Finally, the user experience wouldn’t be complete without sound effects. The auditory aspect is just as important, as some players might miss the ambiance that comes with playing slots at brick-and-mortar casinos.

All in all, it’s impossible to develop an attention-grabbing slot game without taking into account all the factors of entertainment. After all, user experience is what counts.

Future of Online Slot Machines

The technology behind slot machines is continually evolving. As a result, machine learning has already become an option for game engines, so, soon enough, we can expect game developers to start using AV/VR technologies more consistently. Furthermore, artificial intelligence is also likely to become more present in developing new gaming options.

Take, for example, an event from 2019, when two game developers came up with a concept of how slot games could look in the future. Their idea was to train robots to develop mobile games, but they failed to make the automation intuitive enough. Although their attempt was not successful in the end, this is a great example of how developers plan to approach game progression in the future.


Hopefully, this article has brought you closer to understanding the technology behind online slot machines. Even though the way they work isn’t as complicated as it sounds, it is much more advanced and complex today than it used to be years ago. 

Since you have also learned what online slot machines could look like in the future, you can now decide whether that’s something that might spike your interest as time goes on.
