Who Tests Fairness of Online Casino Games

Who Tests Fairness of Online Casino Games

Given how many crooks are among online gambling entrepreneurs, it would be silly of us (online casino players) to take their word on such an important matter as the fairness of online casino games. Moreover, gambling commissions around the world feel the same way and require online casino games to be tested before an online casino gets a license.

As you may have concluded, fairness tests would not be possible without some independent third-party company that has personnel with required technical skills. And, what is most important, such a company must have an impeccable reputation in the industry.

In this article we are going to talk about:

  • what components of online casino games (both slots and other games) are tested

  • what companies are in charge (including their contact info)

What do fairness tests include?

Every online casino game (both slots and classic casino games), in order to be deemed as a fair one, must meet these criteria:

  • All outcomes of the game must be distributed randomly.

  • An online casino must not have an opportunity to affect outcomes of the game after it has been approved.

Therefore, the job of casino games testing companies is to make sure that both above-mentioned statements are true. But how do they ensure it?

Speaking about the randomness of outcomes, as we all know, each online casino game has some RTP (return to player) percentage, which is a crucial part of it. So to say, testing companies need to establish whether claimed RTP is correct or not. For example, an online slot has a theoretical RTP of 97%. A testing company usually makes millions of spins in this slot and compares the result with theoretical RTP. And if they match, then such game is good to go and can be served to online casino players.

After that, a fairness testing company need to ensure that randomness stays intact after the game has been approved and become accessible to online casino players. I won’t dive too deep into this topic since it is quite a geeky one, but everything comes down to ensuring that RNG (random number generator) software is implemented in a proper way and separated from online casinos’ web servers so that they can not affect RNG.

Hence, fairness tests can be divided into these groups:

  • Pre-license tests. These tests are performed before an online casino game enters the market.

  • Tests of existing games, which ensure that a particular online casino game is fair at any moment in time.

Now, as you have gotten some general idea about how fairness tests are conducted, let’s talk about the companies which perform them.

  • They are companies with decades of successful work behind.
