Online Casino Fairness Test Labs – Europe

iGaming Test Labs, which you might know as gaming systems testing agencies or online gambling testing labs, are third-party organizations that provide independent analysis and certification for online casino, gaming, and gambling sites in Europe and worldwide.

These organizations ensure that the games in online casinos we play uphold fairness, randomness, and integrity.

By thoroughly testing the Random Number Generators (RNGs), these testing labs ensure that the element of chance in casino games is genuine and that no undue manipulation takes place – a point of concern we, as players, certainly value.

They also assess the security and reliability of gaming systems.

And when a European online casino obtains certifications from a reputable iGaming test laboratory, it shows its commitment to fair play, player protection, and responsible gambling practices. 


eCOGRA (e-Commerce Online Gambling Regulation and Assurance) is a key trustmark in the online gaming world that was established in 2003. The goal was to bring regulation to a then Wild West-like environment.

It’s based in the United Kingdom, and this independent body works to uphold the principles of fair play and protect us, the players, in the online gaming industry.

  • eCOGRA focuses on fair gaming, player protection, and responsible conduct. They were the pioneers in the self-regulation of online gambling operators, casino game developers, and service providers, which we can all appreciate. Their Generally Accepted Practice (eGAP) Requirements are a benchmark for best practices in the casino industry. These requirements evolve continually with technology and international regulations.
  • eCOGRA tests and certifies online gambling software and systems, ensuring that every game we play is truly random. In addition, they test security measures to protect our data as players.
  • When online European casinos bear eCOGRA certifications, it signifies these casinos’ commitment to fair play, secure practices, responsible conduct, and compliance with rules set by European and international gambling authorities.

In its two-decade journey, eCOGRA has achieved global jurisdictional approvals from Gibraltar to Kahnawake, Italy to New Jersey. With multiple accreditations, it oversees compliance testing for various jurisdictions, providing assurances of integrity for players and regulators alike.

Casino Game Test Labs: Answers to FAQs

What are fairness test labs in online casinos?
Fairness test labs are independent entities that ensure online casino games operate fairly and randomly, thereby maintaining a trusted and transparent environment for players.
How do these labs validate the randomness of the Random Number Generator?
Labs validate the RNG’s randomness by running statistical tests, confirming that game outcomes match expected probability distributions, thus suggesting there are no manipulation or foreseeable patterns. This involves assessing the statistical randomness of outcomes, the RNG’s internal state for integrity, and its seeding, re-seeding, and cycling processes to ensure unpredictability.
The non-repeatability of outcomes is also evaluated to thwart pattern formation and scrutinize the RNG’s scaling and shuffling of random numbers to guarantee unbiased application in games.
What are some reputable online casino fairness test labs?
Reputable fairness test labs in the online casino industry include eCOGRA, Gaming Laboratories International (GLI), BMM Testlabs, iTech Labs, Trisigma, Quinel, and Gaming Associates Europe. Each laboratory is recognized for their rigorous testing procedures and adherence to industry standards, with detailed descriptions available here on this page.
What are the certifications indicating a game’s fairness?
Certifications indicating a game’s fairness differ between labs, but usually, a “Seal of Approval” from eCOGRA or a “Certification” from iTech Labs denotes that the game has passed its fairness testing procedures.
How are live dealer games tested for fairness?
For live dealer games, fairness is ensured through a complete audit of the live dealer software providers’ operational processes, their dealers’ training, and their equipment functionality.
How can players ensure data security while playing casino games?
Data security in online casinos is maintained through encryption, secure protocols, and compliance with regulations such as the General Data Protection Regulation (GDPR). Reputable EU online casinos often undergo an annual third-party security audit, aligning with specific sections of ISO 27001. For more details, see EU casino data security standards.
What methods do test labs use to assess online casino game fairness?
Test labs utilize a blend of advanced mathematical and statistical analyses, computational algorithms, and thorough software testing methodologies. These techniques aid in a comprehensive evaluation of online casino game fairness.
How frequently are online casino games tested for fairness?
The frequency of testing depends on the jurisdiction and the specific testing company. Most online casino games undergo an initial certification process and then regular audits, usually annually.
How can players access test results for specific online casino games?
Players can usually find test results or fairness certifications on the online casino’s website, typically at the footer of the site or within a dedicated “Fairness” or “Security” section.
What action can players take if they suspect a certified game is unfair?
If players suspect any unfairness in a game, the first point of contact should be the casino’s customer service. If the issue persists, escalate it to the local gambling regulatory body or the testing house that certified the game.
Can test labs guarantee absolute fairness in online casino games?
Test labs strive for absolute fairness, but the inherent nature of randomness includes an element of chance. Thus, absolute predictability or identical results for every player can’t be guaranteed. These casino game testing labs generally ensure that games function within the acceptable boundaries of unpredictability, reflecting real-world probabilities.
