Fairness and Testing

To maintain their integrity and fulfill often stringent licensing conditions, online casinos do their utmost to assure players their products are fair and safe. Licensed casinos are required to ensure customers’ personal information and payment details are kept safe, and that all games use algorithms that ensure completely fair and random game results. 

Regulators meticulously ensure these requirements are met before granting a license, and when it comes to game fairness, they work with selected testing companies. In fact, each game a casino offers must be approved by an accredited test house before it is made readily available to customers. With that being said, most players do not know much about testing companies and how they work. In this article, we will cover what it actually is these companies test and how they do it. We will also discuss why game testing is so important, what additional services testing companies offer and reveal the names of the industry’s most reputed companies.

What Is It That Testing Companies Do?

There are several accredited testing companies, and the numbers vary depending on which jurisdiction the casino operates in, and the licenses it has to obtain.

In the UK for example, there are currently nine accredited testing companies helping the UKGC certify that licensees are offering fair games. In other words, these testing companies play an essential role in ensuring that UK no deposit casinos are fair and safe.

What Is That Makes Game Results Fair?

To better understand what testing companies do, you first must understand what defines a fair game result. To put it simply, a fair game result means that the outcome of a game round is not predetermined, but entirely random.

To assure a fair game result on every round, game developers use something called RNG (Random Number Generators). These generators are essentially algorithms that ensure each spin or hand has a completely randomised outcome.

Casino games also have an in-built RTP (Return to Player) which ensures the house gets a small margin of the stakes. If a game has an RTP of 97%, for instance, it means 3% is the casino’s profit.

The remaining 97% of placed stakes are distributed as wins amongst the players. Therefore, RNG engines and RTP percentages are the two most critical things for a test house to examine and verify.

How Testing Companies Ensure That Games Are Fair

In a nutshell, testing companies ensure RNG engines are working as they should and that RTP percentages are accurate and up to date.

By conducting extensive and elaborate tests, these companies verify that game results in a particular game are, in fact, completely random. They will also monitor an incredibly vast amount of spins or hands to verify that the RTP percentages given by the game developer or casino are accurate. They will then publish these figures in regular reports for the sake of transparency and customers’ peace of mind. You usually access these reports by clicking on the company’s logo, which you will typically find in the casino’s footer.

Apart from these essential tests, many testing companies offer additional services. It’s not uncommon for these companies to provide consultancy and management services which help operators overcome the many challenges associated with multijurisdictional operations and compliance.

There may be varying conditions from one jurisdiction to another, and it is important for a casino to stay compliant in all jurisdictions in which it operates. For instance, some jurisdictions, such as the UK, have incredibly stringent rules when it comes to Responsible Gambling practices and marketing. If a casino fails to comply with these rules, it might receive hefty fines, or at worst, have its license revoked.

Why Do We Need Testing?

Testing casino games is an elaborate, time-consuming and complex process. If there were no testing companies, there would be no way for players to know whether they have had a fair chance of winning. Simply trusting a casino’s game results are fair isn’t good enough, and just like in many other businesses, independent third-party auditing is warranted.

The Most Important Testing Companies

There are several approved testing companies working closely with various licensing bodies.

Here is a summary of the most prominent ones:
