How Online Slot Games Are Tested for Fairness and Randomness

Online Slot Games

If you enjoy playing online slots at Dream Jackpot, you may wonder how fair they are. Contrary to some sceptics’ unwarranted beliefs, reputable casinos ensure that their games are fair and random.

But how are online slot games tested for fairness and randomness? Let’s find out below.

Random Number Generators

The randomness of any online slot game is determined by the game’s random number generator (RNG). RNG is a software that uses codes to generate strings of random numbers. These strings are so random that gamers have an equal chance of winning or losing. Therefore, every spin of the reels is an independent and unique event. So, the results don’t affect any future spins. Random number generator software is separate from online casino web servers, so an online casino can’t affect the outcome of the games.

Return To Player Rates

Another way to ensure players’ fairness is through the return to player percentage. While the random number generator ensures the randomness of the results, the RTP rate ensures that a percentage of the money players wager is returned to them.

In addition to the RTP ensuring players receive back some money, a certain percentage goes to the casino. That is why online casinos don’t need to rig games, even if they could, as the RTP always gives them a house edge.

Slots maintain the RTP in the long term, which is why gamers can potentially experience losing streaks. With the RTP in place, along with RNG, you can never know when a payout will occur.

How are Slots Tested for Fairness?

While RTP and RNG ensure fair gameplay, slots still need to be tested by third parties. For instance, a testing company can establish whether a game’s claimed RTP is correct. It does that by repeatedly testing the game and comparing it with the theoretical RTP. If the two values match, a game is certified as being fair. In addition to testing games before they are released, the testing agencies also test the existing games to ensure they are fair to play at any time.

Who is Responsible for Testing Slot Games?

Although each country has its gaming regulatory authority to ensure that online casinos are licensed, regulated, and fair, independent companies test the fairness. Some of the most popular casino software testing agencies include the following ones:

  •         eCommerce and Online Gaming Regulation and Assurance (eCOGRA):  eCOGRA is an accredited testing company based in the UK and works in many gambling jurisdictions.
  •         iTech Labs: This Australian company has been operating since 2004. It has other offices in Spain and Italy. iTech has a strong reputation in the online gaming industry, and its team has tested many online casino games.
  •         Technical Systems Testing (TST): TST has been well-known for making a fairness test for online and land-based casinos since 1993.
  •         NMI: This is a European-based company with labs in Germany and the UK and headquarters in the Netherlands. The company has gained popularity and trust since it has been operating for over 30 years.
