Checking and testing online casinos

⭐ Reliable operators and providers: testing and verification

Audit and certification for online casinos is an independent and transparent examination of payouts, business structure, various documents and other information with the goal of forming an opinion about the fairness and integrity of the games.

During the process an auditor from the auditing organization collects facts and analyzes the situation without fear of accusations from the company being inspected. This is the factor of independence. Transparency is ensured by making the obtained data, conclusions and the methods used publicly available in the form of a report. The examination is carried out by collecting information from various sources. Actions taken should not interfere with the activities of any of the parties (the auditor or the casino).

Auditors get full access to any information relevant to the specific assessment. For this, a representative of the organization records different types of data, and gambling companies are required to ensure integrity, completeness and uncompromising transfer of information.

Why modern gambling market certification is needed

Today a competitive gambling resource must include:

🎰  a huge amount of high-quality gambling content  – slots created by professional developer teams, presented on platforms with uninterrupted operation. Game payouts should be high and match the documentation, and the operator must not be able to influence algorithms or change the long-term return-to-player percentage;

💱  methods for deposits and withdrawals that eliminate any difficulties and delays  – an operator focused on a certain segment or territory should take into account the most suitable payment systems for that region. If a method works only in one direction (only for deposit or only for withdrawal), that information must be clearly visible;

🎁  incentive and reward programs  – welcome bonuses, cashbacks, loyalty gifts, promotions and tournaments. Without these, the development of a modern gambling portal is doomed to fail, no matter how much honesty and reliability it promises. Today you cannot imagine a gambling site without gifts, casino promo codes and prize draws. Moreover, wagering rules for bonuses should be clearly explained and have no hidden traps. Players must be informed in advance of any changes and, if this causes them any inconvenience, the casino should provide moral compensation to the customer in the form of free spins, additional bonus credits or other rewards.

All these aspects must be executed at the highest level. But the characteristics of real quality can be examined even more thoroughly and in detail. This will help better understand what testing labs and independent organizations that certify gambling brands, their products and services do, and how they differ from licensors.

Why casino and gaming equipment testing is needed

The thing is, checking gaming equipment or a slot is needed not only so that a player can place bets calmly and be sure the game is fair and the return is as the online slot developer or the machine manufacturer advertised. Testing is also needed by the side providing gambling services, whether operator or provider. They also need to make sure the game won’t crash and the algorithms work without errors. Bugs can not only cause losses to the gambling establishment but also affect its reputation. A damaged reputation reduces visitor flow and, consequently, affects revenue.

For example, there was a case when an elderly woman in Australia was playing a slot and its display suddenly showed a jackpot win of $65,054. She was overjoyed until a casino employee approached, stared at the slot and said he could not pay that sum. It turned out the game should not have paid out amounts over $10,000. That was, of course, a nice win for the pensioner, but the slot displayed a much higher number. The casino’s reputation was tarnished. Perhaps the best solution would have been to pay the $65k and then investigate the matter with the gaming equipment manufacturer.

There are many similar stories.

There are also people who deliberately look for bugs in slot software to exploit them.😎 The story about casino fraudsters mentions real geniuses who found weaknesses in slot machines, hacked them and scored solid wins.💰

Undeclared features and the MegaJack slot tweak example

A company testing equipment also strives to eliminate hidden options that allow slot settings to be adjusted by gambling operators against players.

The manufacturer itself may leave undocumented functions to sell them to unscrupulous arcade owners who want to profit by lowering the payout of the machine.

This brings to mind the MegaJack slots (the ones with Pyramids, Champagne, Multi-deck Poker). They were successfully tuned by owners themselves. Even on themed forums you can find threads from 10-15 years ago discussing how to configure the Bulgarian-made machines. Here are a couple of screenshots from those sites.

How to configure MegaJack, fig.1
How to configure MegaJack, fig.2

To prevent such DIY tinkering various organizations work to defend players’ rights and create maximum fairness in outcomes that already depend on chance and luck.

🗜 Well-known gambling testing labs and their working specifics

Looking at this more broadly, it should be noted that some testing laboratories from the US, Australia and Europe have proven themselves best.

The first testing organizations began offering their services when electronic circuitry was added to the construction of gambling machines and game results became dependent on software algorithms.🔢 That period was in the late 1970s.

Then more innovations appeared in the gambling sector – online casinos being among the most significant. Accordingly, demand for tests and audits grew. 📊

Among the well-known testing laboratories are: SQS, BMM, TST, iTech Labs, Gaming Associates, NMI, GLI.

GLI is currently considered the best. But that does not mean the other mentioned labs are incompetent. Each employs professionals, monitors trends and follows new technological developments. You can learn more about an organization by selecting it in this section and reading its review.

These organizations approach their duties professionally and responsibly, keep up with new trends and apply the latest methods and technologies during inspections.

What testing labs check and verify

Each testing structure may have its own approach, work scheme and applied technologies, but in general several main points can be singled out that are focused on during verification:

RNG (random number generation) – one of the most important elements of online gambling, as it is responsible for the randomness of each spin or round. RNG is connected to many game attributes. Its verification considers:

  • the impartiality factor – that each number has an equal chance of appearing, and
  • the unpredictability factor – elimination of repeating sequences that players could exploit.
Slot check: left – non-random RNG distribution, right – random

Mathematics – absolute accuracy and absence of deviations. This especially concerns payouts, bonus calculations and correct rounding of fractional values.

Slot check: periodicity and absence of periodicity

Rules of the game – every gambling entertainment must be accompanied by a detailed and clear description, and the gameplay must follow those rules. Sometimes testers spend a lot of time studying every clause to ensure they are strict and contain no unmentioned details.

In addition, usability, localization, scalability, security and elasticity of the gaming system are checked.

The service list also includes:

  • pre-release audit of a gambling game,
  • platform certification for betting,
  • mobile testing,
  • multilingual functionality checks,
  • expertise in correct currency conversion,
  • assessment of necessary investments to comply with established standards,
  • tracking hidden collusion and fraud capabilities and ways to eliminate them,
  • effectiveness of international customer protection,
  • presence of critical modules that could allow unauthorized access and changes,
  • and other exclusive types of testing at clients’ request.

All this contributes to truly high-quality service provision and increases the reliability of the gambling business.

Omissions and mistakes found during tests

Perfectly executed products are very rare. During initial and subsequent testing some flaws are revealed, even when the manufacturer believes everything is perfect.

Common errors often found when testing gambling equipment and software include:

  • design problems,
  • uncomfortable placement of gambling elements on the screen,
  • inactive buttons,
  • incorrect calculation and awarding of bonus round results,
  • logical inconsistencies in scenarios,
  • crashes when accessed from mobile devices,
  • incorrect calculations when converting currencies.

Experienced testers pay immediate attention to regularly recurring errors. Special programs are developed to detect them much faster during checks. But because some developments are unique, each game or platform receives an individual approach.

📃 Gambling industry licensors

Licensor is an organization above the testing lab whose work is directly related to laws adopted by a country’s government on organizing gambling. It sets certain standards and also checks the testers themselves to see whether they are competent to do their job.

Before issuing a license, the regulatory body carries out the following steps:

studies the provided information about the future operator’s financial accounts – availability of insurance, reserve funds and other confirmations that the casino can meet its financial obligations to players;

whether the equipment meets minimum requirements – this includes player data security, comfort while using the gambling site and its services;

whether the entrepreneur wishing to operate in the online gambling market has a criminal past;

professionalism of the gambling portal’s staff.

The support service should have qualified representatives able to calmly and politely answer customer questions and point out every little thing.

So if you encounter a site where support is not quite adequate, that is a reason to doubt its level and whether the license or certificates are genuine. In any case, it is a strong reason to complain. And if the resource received a license in Malta or the UK, you can boldly write to the regulator about inappropriate treatment of customers by the online casino. ✒️

💾 Not to mention refusal to pay out your winnings or the obvious use of fake software. It makes sense to report detected scripted software to 4LUCK so that fraudsters are added to the casino blacklist, and the aggregator of gambling sites has a complaints section to help in disputes with operators.

Information about countries and companies involved in gambling control and regulation is presented in a separate section 👇

But a casino that has no license at all should be considered a blatant scam. If you are new to online gambling and looking for a regular platform, be careful in your choice. It is best to pay attention to establishments that have received the highest ratings. They provide the greatest guarantee for the safety of your funds, personal data and licensed software.</message]

Independent certifying organizations: eCOGRA

Companies like eCOGRA are independent regulators of the gambling sector and their scope of work includes much more than testing labs. They review developers’ software and inspect gambling sites for security standards and test staff qualification levels.

eCOGRA

A certificate indicates that an operator or provider has passed the check. And although eCOGRA does not issue licenses, its mark tells people familiar with the industry a lot.  An eCOGRA certificate is an indicator of reliability even greater than some licenses.  It is worth adding that the British independent organization ranks higher than the Curaçao jurisdiction, which rarely pays attention to player complaints.

eCOGRA has a controlled body – SRS (Self Regulation Services) whose main tasks include protecting gamblers’ rights, creating a safe environment for players, providing support and monitoring compliance with fair play conditions.

Another eCOGRA body – ATA (Approved Testing Agency) directly inspects online gambling sites, tests software and issues relevant certificates.

Independent casino audit

Independent audit is an important process that not only supports players but also helps service and equipment providers prove they are honest and do not deceive clients, thereby securing their position in the gambling market niche as trustworthy operators.

⚙♦💲 Modern gambling contains many elements and details requiring special attention and precision, since it involves financial transactions and complex mathematics. The owner of a gambling establishment is not obliged to understand every aspect, although they should strive to.

Identifying gaps in the gambling portal’s operation, staff qualifications, equipment accuracy or missing components for higher-level operation – this is the main task and significant help provided by an independent casino audit.

To sum up

Ultimately, a fair casino is one whose activity adheres to four principles:

  1. The game operates the same way as in other similar establishments (the software is not counterfeit);
  2. Games have passed a set of statistical tests designed to detect bias;
  3. The game remains statistically stable over a certain period;
  4. The game has no operational flaws that would allow a player or casino staff to alter it.

Finally, when reasonable conclusions are reached, the authority issues a certificate proving that the online casino meets certain iGaming industry standards.

In this section you can view which casinos undergo testing and/or certification by which authority or organization.
