Gambling Auditors: Complete Guide

In most gambling jurisdictions, casinos and online casino software companies must submit for independent testing. This is the seal of approval that says the game, software or casino platform:

  • operates exactly as designed and advertised, in compliance with operational and legal protocols;
  • pays the advertised rates of RTP (return to player);
  • uses a fully functioning RNG (random number generator);
  • is not rigged or unfair.

Why are Casino Audits and Independent Testing Services Important?

The reliability and fairness of casino games is an understandable concern for online casino players, particularly newbies. Thanks to top-tier gambling regulators such as the UK Gambling Commission, and the creation of independent technical test houses such as eCOGRA and iTech Labs, this is no longer a prime concern for players who know when they see a testing lab’s stamp of approval, everything is above board.

For casinos, submitting to auditing and tests proves they are transparent, fair and it can also help them stay ahead of the curve as industry regulations change frequently. Audits are also helpful when it comes to the casino yearly licensing audits - as they will already be aware of any problem areas and have worked to resolve them.


ecogra“The underlying philosophy of eCOGRA is based on the achievement of the objectives of player protection, fair gaming and responsible conduct by operators, software providers and relevant service providers.” eCOGRA (2003) 

eCOGRA (e-Commerce Online Gaming Regulation and Assurance), is probably the most well-known casino testing lab, their stamp of approval and legitimacy appearing on casino and casino software websites everywhere including industry giants like NetEnt and co-founders Microgaming.

  • RNG and RTP Audits: eCOGRA undertakes data monitoring, output measurements, testing and certification of game RTP (return to player) and RNG (random number generator) for over 100 casino sites. It is this testing that verifies and ensures a game generates its theoretical rate of RTP, compares it with actual game results, and ensures is fair in its results.
  • Alternative Dispute Resolution Service: Lastly, eCOGRA is a recommended ADR service, which is an important and independent role when casinos cannot solve disputes with players internally.
