How slot machines are tested and certified
Introduction
Before the slot gets to the online casino or slot machine hall, it undergoes a multi-stage check. The goal is to ensure the integrity of the random number generator (RNG), compliance with the declared RTP, data security and the absence of vulnerabilities. Certification guarantees players transparency of mechanics and protection of their interests.
1. Submission for audit
1. Developer application: the provider submits to an accredited laboratory (eCOGRA, iTech Labs, GLI) a full package of documents: a description of the RNG algorithm, mathematical model of payments, source code or executable assemblies.
2. Preliminary analysis: the laboratory verifies documents, checks compliance with the declared specification and appoints a team of testers.
2. Random Number Generator (RNG) Testing
1. Statistical analysis: verification of the uniformity of distribution of results across millions of virtual spins. Criteria for χ ², Kolmogorov-Smirnov and other methods of testing randomness are applied.
2. Check correlations: make sure that the results of individual spins are independent of each other and do not form repeating patterns.
3. Local and server testing: if the slot works partially in the browser, both links are tested - the client part and the server where the main logic is launched.
3. Verification of RTP and volatility
1. Mathematical calculation of RTP: based on the table of payments and symbol weights, a theoretical long-term return to the player is calculated (usually 92-98%).
2. Empirical confirmation: the laboratory simulates large sessions (tens of millions of spins) and compares the actual average return with the declared one.
3. Volatility check: analysis of the variance of winnings, the ratio of frequency and size of payments to confirm the declared level (low, medium, high).
4. Safety and compliance audit
1. Cybersecurity: vulnerability checking - XSS, SQL injection, data leaks; testing the security of transmission channels (SSL/TLS).
2. Platform specifications: compliance with HTML5 standards, mobile and desktop compatibility; checking work on different browsers and devices.
3. Regulatory requirements: compliance with the rules of a particular jurisdiction (MGA, UKGC, Curacao, etc.) - age control, protection against money laundering, provider liability.
5. Issuing a certificate and publishing a report
1. Final conclusion: if all tests are passed, the laboratory issues an official certificate indicating:
6. Post-Release Recertification and Control
1. Periodic checks: annual or when the mathematical model of the slot changes, tests are repeated to confirm the validity of the certificate.
2. Anomaly monitoring: the laboratory and the regulator can launch an unscheduled audit if there are complaints about the incorrect behavior of the machine.
3. Software updates: after the release of patches or new functions, the developer is obliged to provide an updated version of the slot for re-audit.
Conclusion
Testing and certification is a comprehensive process that includes RNG audits, RTP and volatility checks, security, and regulatory compliance. Regular checks and transparent publication of reports provide players with confidence in the honesty and reliability of slot machines.

5. Issuing a certificate and publishing a report
1. Final conclusion: if all tests are passed, the laboratory issues an official certificate indicating:
- Slot version and audit date
- Value of RTP and volatility
- Laboratory name and accreditation
- 2. Publication: the provider places the laboratory logo and a link to the report on the website and in the slot description, and the casino - the "Certified RNG" icon or similar.
6. Post-Release Recertification and Control
1. Periodic checks: annual or when the mathematical model of the slot changes, tests are repeated to confirm the validity of the certificate.
2. Anomaly monitoring: the laboratory and the regulator can launch an unscheduled audit if there are complaints about the incorrect behavior of the machine.
