Decoding the Technology - Online Casino Software Explained

Before we explain you how online casino software providers work, it is important to know what a casino operator actually means. You will see that the software developers are also called providers or software providers in the online gambling industry.

The name speaks for itself so basically, online casino software providers offer gambling products and services, but mainly, casino games. The way they develop all of their products focuses on the aesthetic aspects, as well as on the safety, security aspects, and overall good performance.

On our platform, you can find a wide selection of slots from the best casino computer software suppliers. You can even choose to display games with specific features. Learn more from our cool guide about how to navigate the game selection.

The providers are usually independent of the online casinos and the variety of games they create can be found and played on multiple gambling platforms. Let's break down some of the systems used by software providers.

RNG - Random Number Generator

One of the basics of casino software solution is the RNG, short for Random Number Generator. This system is used in many industries, from cryptography to games of all sorts, including casino games.

This gaming technology aims to provide an unpredictable set of numbers. 

This way, neither the house nor the players can predict what number will come up next, resulting in game fairness.

Depending on how the numbers are generated, this software can be grouped into two types:

True Random Numbers Generator (TRNG)

The True Random Number Generator is a kind of external gadget that casinos connect to their server through a USB port. It takes the form of a small card or chip contained in a device that produces a random series of numbers triggered by unstable atmospheric phenomena or physical processes.

This type of RNG is also used in land-based casinos. Once connected, the device uses compound values ​​as a starting point to get the outcome of, for example, a roulette game. Contrary to what many people think, the True RNG cannot be hacked, because it is placed inside the machine and firmly fixed.

Pseudo Random Numbers Generator (PRNG)

The Pseudo Random number generator is a tool used to secure the randomness of online casino games. Unlike true TRNG, this is software that offers a mathematical algorithm and not a physical device. This program code is therefore responsible for generating random numbers and determining the outcome of games.

It constantly produces new sequences of random numbers. Its starting point is a number with millions of digits after the decimal. Then, from this starting number, many mathematical operations are carried out automatically to calculate the additional value and generate the result of a game.

Game providers also integrate it during the production of their titles to guarantee their reliability.

One of the oldest and most common algorithms used for PRNG is called Linear Congruential Generator, but if you want to get super in-depth, you can even learn about the math behind this whole process.

How Does RNG Work in Slots?

Let's take slots as an example. You press the spin button and the reels give out some combinations of symbols. Behind them is the RNG which generates a value between 0 and approximately 4 billion.

The software of the slot then translates this value into a specific set of numbers, corresponding to the symbols on the reels. The RNG starts generating a new random value every time you deposit a credit coin or you hit the spin button.

You can also look at the RNG as an algorithm representing a series of software instructions to generate the numbers. And to get a bit more specific, it seems most likely that online slots use the Pseudo Random part of the whole RNG process.

Who Checks the RNG Software?

The RNG of a software provider is usually tested by a testing and certification laboratory. Some of the ways the RNG is evaluated are through

  • Constant evaluations, verification and reporting

  • Game mathematics evaluations

  • Penetration testing, and security audits

Here are the most well-known auditing organizations:

  • TST: TST is well known in the iGaming industry for its technical audits of RNGs and other lottery and sports betting operators. It also ensures that poker systems are not vulnerable;
  • eCOGRA: This is one of the biggest names in this industry. The company is based in London and is committed to fair gaming and responsible operator conduct. In addition to auditing RNGs, its test evaluates casinos on a large battery of criteria, to certify only the most reliable platforms;
  • Verisign: Based in North America, this company offers a range of security services and is recognized as an expert in cyberattacks.
  • Gaming Associates: is one of the leading consultants to the iGaming industry on regulatory, security, and fairness issues. Since the 1990s when gambling regulation really escalated, GA has been working with operators to ensure they are in good standing and therefore using safe and fair RNG.

RTP - Return to Player

The Return to Player represents the percentage of the total money wagered on a game that has the potential of returning to you as a win. You could easily associate it with online slots, but it is used on all online casino games.

The Return to Player percentage is usually visible through the game settings or info, where the provider advises on a theoretical RTP. It is important to keep in mind that casinos cannot manipulate the RTP in any shape or form.

Moreover, this percentage can sometimes be just a number for players. If you want to play short sessions occasionally, the RTP can remain only as orientative, but if you engage in long sessions, the percentage can be meaningful when creating a gambling strategy.

To calculate the RTP, free online casino software providers take the amount returned to players and divide it by the total amount gambled by players. Usually, slot games Return to Player vary between 80% to 98%. Sometimes, casinos exclude games with higher percentages from contributing to wagering requirements of different bonuses.

In different types of games, as a player, it can be easier to figure out how much the game will payout. With slots, things can be trickier as you cannot completely predict when a slot will payout, but we will talk about that in a moment.

Volatility and Variance

These two concepts are slightly different and they can be confused as being the same term with different names. Well, that is not quite right. It is true that they both express the distribution of results of a slot, but they measure it differently.

Mainly, Volatility and Variance help us know when a slot will payout and they express the possibility of losing or winning a session. How volatile a game is really depends on the algorithm used by the game developer. You know, the same algorithm that creates in-game randomness that we talked about earlier.

Volatility measures the potential of winning based on a specific time period. For example, Volatility will measure the difference in weekly payouts within a month. On the other hand, Variance will determine how likely results are to change in the long run.

Levels of Volatility

Both of them have more levels: Low, medium, high, and combinations. The basic idea is that the higher the level, the higher the risk, the higher the wins. From our designated guide you can find out more about volatility and variance.

  • High

This level is suitable for High Rollers that have a big amount of money to spend. Slots with this level require a lot of patience and consistency as it can take a considerable amount of time until a big win hits.

  • Medium - High

If you consider yourself a High Roller, you can play games with this Volatility and expect frequent small wins.

  • Medium

Play slots with medium Volatility if you want to take moderate risks and moderate wins, which has the potential to give you a shot at the jackpot.

  • Medium - Low

If you have a limited budget and want to entertain yourself, Medium to Low Volatility slots are a great idea, as they can offer small wins in a faster manner.

  • Low

This type of Volatility is perfect if you do not want to spend little money, and have fun for short periods of time. Slots with low Volatility will offer you small, but more often wins.

What are the main similarities and differences between slot software providers?

One of the greatest things about the era we live in is that you have the opportunity to choose from many options of online casino software developer. What some software developers may lack in game variety, they can make up for exciting bonus features.

Every software provider has to stand out from the competition. One way they will do that is by having a unique style of designing their games. These unique differences can sometimes be seen even in the way providers decide to organize the settings, spin, or bet value buttons.

Before that, let’s mention the similarities between slots software. The obvious is that they all strive to bring high-quality products to their customers. This is done by implementing technologies, such as HTML5 which also allows games to be compatible with every device.

HTML5

html5 logo

For some time now, all software providers have been using HTML5 technology when creating a casino game. If you regularly navigate the web, you sure heard about HTML5, but what does it mean? Well, it is a programming language and the acronyms stand for Hyper Text Markup Language.

This language is the code that describes the structure, but also the presentation of a web page. This helps developers to create dynamic, interactive applications, web content, and everything in between.

Before HTML5, developers were mainly using Adobe Flash, which was used in the same way, but it didn't have as many characteristics. Around 2020, Flash was phased out, allowing brand new casinos to take advantage of HTML5.

This technology gives players the ability to play any casino game without the need to download any app and they can also play from iOS devices, which was not really possible with Flash. Additionally, HTML5 proved to be safer, more stable, and cooler, by the possibility of adding cutting edge graphics and sounds to a game.

Playtech, one of the online casino software providers we talked about earlier on this page, was one of the first developers to implement the HTML5 technology in their gambling products. After that, Microgaming, IGT, NetEnt, and other big providers used it.

Licensing & Certification

Another aspect that should be present with every provider is the licensing and certification. Usually, providers take it very seriously to have proper licensing from recognized gaming authorities.

Moreover, certification is important to ensure game fairness, this way players can be sure they are playing safe and secure real cash slots. As we mentioned earlier, the testing companies make sure that the RNG system is providing complete randomness.

Discover the Types of Casino Software

The products of casino software providers can come in different shapes, and we can put them in a few categories, as follows:

  • Online Casino Software Download

When you encounter these types of casino software, it means that you have the option of downloading an app where you have everything in place and you can even add the app on your home screen for quicker access.

  • No Download Software

Also named Instant Play Software, these types of casinos allow you to play right from the browser without the need of downloading anything. Just access the casino from the browser and play right away.

  • Mobile Software

The software is well adapted to mobile devices, even if you access it through a browser or app so you can easily play mobile slot machines.

  • Desktop Software

Very similar to Instant Play, Desktop Software allows you to enter a casino and play its games without the need of download. Just access it through a browser and you're good to go!

  • Live Casino Software

This type ensures you can play table games such as poker, baccarat, or roulette, in real time with real players and benefit from live support that can assist you with different queries. Evolution Gaming, Ezugi, Playtech, and Net Entertainment are some of the experts in Live Dealers Casino Software Providers.

  • VR Casino Software

As the name suggests, this software type allows you to play online casino games using a VR operating system. They will bring the experience of a real casino everywhere you go. You just need a VR headset and a good internet connection.

How to Choose the Best Slot Machine Software Providers?

Online casino providers even offer other services besides games and it is totally alright to wonder how to make a good decision for a good gambling session.

Below we shared some keypoints that could help you make a good decision because when you are choosing a casino, you're also choosing the best online casino game software. 

Software Type

As we mentioned before, there are several types of casino software. Some players may prefer instant play (at the expense of some degree of visual quality), others have no issue downloading third-party software if it means playing their games on high performance.

Cross-Compatibility of Games

As we previously mentioned, most software providers optimized their games to be compatible with any kind of platform, PC or mobile. If mobile gambling is particularly important to you, then you should make sure the casino software includes this feature.

Language Support

Depending on where you’re playing from, check to see if the online gambling software of your choice supports your language. English may be widely spoken, but it’s great to be able to navigate a website or chat with the support team in your native language.

Licensing and Payment Methods

Usually, software providers can have in their casino solution the license and payment methods in order to help casinos with creating a good working business.

When signing up at a casino, check their license provider as well as the available payment methods. Ideally, the casino should have a recognized gambling authority and familiar, trustworthy payment options.

Game Variety

Players tend to gravitate towards popular game developers with massive portfolios, but keep in mind that this is not always the best indicator of quality. Some small, lesser-known software providers might have smaller portfolios with great games ready to be discovered.

Graphics

No matter how great the gameplay is, some players will always give up on a slot if its visual quality is bad or even just below average. Appearances are important and casino developers are always working to design games with great graphics in order to deliver a complete gaming experience.

Audio

For those times when you’re playing the game during your downtime, the game soundtrack might be important and even instrumental in getting you in the mood for the game.

Stability

It’s crucial that the slot machine software of your choice is reliable and stable. If you choose software that freezes at the single worst moment and gives you frequent errors, then it’s not the software for you. Look up information and reviews about a particular casino software supplier before you start playing to avoid these unpleasant situations.

Country Restrictions

Some software providers may choose to not make their products available to certain countries, for different reasons. For instance, Microgaming and NetEnt casino software developers are not available to most US players. This can be very inconvenient so make sure you check that the gambling software you choose is available for players from your region.
