Overview

Random Number Generator (RNG) Certification is the process of independently verifying and examining the fairness, unpredictability and integrity of a digital RNG system. RNGs are the backbone of games of chance—such as online casinos, slot machines, lotteries, and gaming software—where results must be provably random to ensure fair play.

This certification is carried out by the independent, ISO/IEC 17025-accredited testing laboratories, which follows the global standards and norms to assess whether an RNG operates as claimed. The evaluation involves rigorous mathematical, statistical, and security testing to ensure compliance with industry regulations and fairness standards.

Why

Certifying an RNG system is not just about ticking regulatory checkboxes, it is central to building a secure, transparent and trustworthy gaming environment for all stakeholders.

• Ensures Fairness: Certification guarantees that the outcomes generated by the system are statistically random and free from bias or manipulation.
• Builds Trust: Certified RNGs enhance credibility with players, regulators, investors and other stakeholders.
• Regulatory Compliance: Most regulated jurisdictions require RNG certification as a prerequisite for obtaining gaming licenses.
• Protects Operators: Certified systems reduce the risk of fraud, legal disputes, or license suspension.
• Global Market Access: A certified RNG system is more likely to gain approval in international jurisdictions, expanding the operator’s market reach.

Process

The certification process typically includes the following steps:

1. Application Submission

The developer or operator submits a request to an approved testing lab, along with required documentation and source code.

2. Source Code Review

Expert auditors examine the RNG's source code to assess algorithm integrity, logic flow and absence of exploitable flaws.

3. Statistical Testing

The RNG’s output is evaluated using industry-standard statistical test suites such as NIST SP 800-22, DIEHARD, and TestU01 to ensure randomness.

4. Operational Testing

Simulated gaming environments are used to assess that how the RNG performs under real-world scenarios.

5. Security Assessment

Labs verify secure seeding, tamper resistance, and the quality of entropy sources used in RNG operations.

6. Certification Report

If all requirements are met, the lab issues a detailed certification report, often valid for 1–3 years depending on jurisdiction and any updates made.

Documents 

While specific requirements may vary by lab, typical documents include: -

• Cover letter or formal application.
• Technical specification of the RNG algorithm.
• Complete source code and build instructions.
• System architecture and deployment details.
• Internal QA/testing reports. (if any)
• Company registration and developer credentials.
• Any previous test or certification reports.

Fee 

RNG certification fees vary based on the basis of system complexity, RNG type (software vs. hardware) and the chosen testing laboratory. Approximate costs range between INR 4.5 – 7.5 lakhs.

Note: Professional/consultancy fees may apply if using a service provider.

Timeline 

The end-to-end process typically spans 5 to 9 weeks, depending on code quality and lab availability: -

• Document Review & Pre-Assessment: 1–2 weeks
• Code Testing & Statistical Evaluation: 3–6 weeks
• Final Reporting & Certification Issuance: 1 week

Note: Additional time may be required in case of failed tests, clarifications, or required changes.
