Fairness of Non GamStop Casinos UK? Although online casinos are under the strong supervision and control of legal gambling commissions around the world, many players still doubt the fairness of their games and they believe that these games can be easily rigged. While this may be true for some unlicensed casinos, the same cannot be said for all non GamStop casinos as they are regularly tests by licensing committees which ensures their quality and integrity. In addition to licensing commissions, most casinos without GamStop are certified by independent testing agencies. In this article, we will look into this topic in more detail and also provide you with information about the most prominent casino game audit agencies.

What Are the Roles of Testing agencies?

So who tests fairness of Non GamStop Casinos? Testing agencies are independent, not-for-profit, industry-funded labs that operate under the supervision of licensing committees. These organisations are made up of teams of computer scientists, engineers, and mathematicians who test casino games to ensure their fairness and randomness.

For example, for slot games the RNG is everything otherwise the game will be biased to provide certain outcomes. Thus, players will not have a real chance of winning. Test teams run each game thousands of times to tests the accuracy of the RTP and house edge percentages. If the statistical probability is exceeded, the testing agency will reject the game and if it is established that the casino has already hosted it, the licensing committee will impose a fine or even withdraw the license permanently.

Tests we performed on Slots

It is worth noting that the casino wins in the long run from all the games it hosts. However, it should not keep 100% of the losing players’ bets but it should return 95% to 99% of them to the winning players while keeping a percentage ranging from 1% to 5% of the total bets of the losing players as a profit.

The second thing licensing agencies check is the server that hosts the internal game files. These files should be kept on a well-secured server of the game developer, not the casino. Even if the developer studio belongs to the same company that operates the casino, the games should be kept on the servers of the gaming company. Thus, the casino shows the game only and cannot interfere with the internal algorithms to produce biased outcomes.

In addition, testing agencies also check other things such as the clarity of game instructions, and availability of a free version to allow players to try it out risk-free before deciding to bet real money on it.

Testing of Fairness of Non GamStop Casinos by International Licensing Committees

Testing agencies cannot certify that the games are “fair” without a regulatory body that allows them to test casino games and subsequently approve their reports. To this end, gambling regulatory authorities run extensive evaluation procedures on each testing agency to ensure that their methods are effective and fair.

On the licensing committee websites, you can see the full list of testing committees allowed to evaluate and accredit casino games. If you see the logo of any of these auditors in a non GamStop casino, you can rest assured that all casino games are safe and fair.

Of all the approved testing agencies, some stand out from the rest. In the next part, we will present to you the top 6 test houses that check the outcomes of games hosted by non GamStop casinos.
