What Is RNG Certification and Why Does It Matter?

A Random Number Generator is the algorithm that determines game outcomes in slots, table games, lotteries and other chance-based products. RNG certification is the independent verification — carried out by an accredited testing laboratory — that confirms the RNG produces statistically random, unpredictable and unbiased results, and that the declared return-to-player (RTP) percentage is accurate over the long run.

Regulators, banks and payment partners will not work with an operator or software provider whose games are not backed by valid RNG certification.

Why RNG Certification Matters

Certification is simultaneously a licensing condition, a player-protection mechanism and a commercial precondition for market access.

  • Regulatory compliance

    Virtually every licensing authority requires valid RNG certification from an approved laboratory before a game or platform is authorised for real-money play.

  • Player protection and trust

    Certification confirms outcomes cannot be predicted or manipulated by the operator, the software provider or a third party.

  • Commercial necessity

    Payment processors, game aggregators and platform partners require proof of current RNG certification before onboarding a game or operator.

Which Jurisdictions Require RNG Certification?

Independent RNG certification is a standard licensing condition across virtually all reputable gambling jurisdictions — including the Malta Gaming Authority (MGA), the UK Gambling Commission (UKGC), the Isle of Man, Gibraltar, Alderney, Kahnawake, the Curaçao licensing framework, and the regulated US and Canadian state and provincial markets. The detail differs.

  • Approved laboratory lists

    Some regulators maintain a list of approved testing laboratories (GLI, iTech Labs, BMM Testlabs, eCOGRA, NMi) and accept certificates only from a lab on that list.

  • Platform-level testing

    Some jurisdictions require RNG testing at the platform level in addition to testing each individual game.

  • Recertification is the norm

    Certification is rarely a one-off exercise: most regulators require periodic recertification, and any change to the RNG algorithm or game math model triggers a re-test.

What Testing Laboratories Actually Check

Batteries of statistical tests — chi-square tests, run tests, correlation tests and frequency distribution analysis — are applied to millions of simulated outcomes to confirm the RNG shows no detectable pattern or bias.

How to Obtain RNG Certification: Step by Step

The sequence below is the standard route from laboratory selection to a certificate filed with your regulator.

  1. Select an accredited testing laboratory

    Choose a laboratory recognised in your target licensing jurisdiction(s) — the accepted list varies between regulators.

  2. Prepare the technical documentation

    Assemble the RNG algorithm description, source code and game math model required by the laboratory.

  3. Submit RNG and game files

    Files are submitted to the laboratory under a testing and confidentiality agreement.

  4. Laboratory testing

    4–8 weeks

    The laboratory runs statistical, RTP and security testing over an agreed testing period.

  5. Remediation of findings

    Address any findings or remediation requests raised by the laboratory before the report is issued.

  6. Receive certification report

    The laboratory issues the RNG certification report and certificate.

  7. File with the regulator

    Submit the certification as part of your licence application or ongoing compliance file.

  8. Schedule recertification

    Plan periodic recertification and re-test after any material change to the RNG or game math.

Timelines assume the technical documentation package is complete at submission; incomplete filings are the most common cause of delay.

How RUE Supports Your RNG Certification Process

We work alongside accredited testing laboratories and manage the legal and administrative side of certification, so your technical team can focus on the product.

  • Documentation package

    We prepare the full technical documentation package the laboratory requires at submission.

  • Testing agreement

    We draft and negotiate the RNG certification and testing agreement, including confidentiality terms.

  • Timeline management

    We track the testing timeline with the laboratory and manage remediation of any findings raised.

  • Jurisdictional scoping

    We align the certification scope with the specific technical requirements of your target licensing jurisdiction.

Frequently Asked Questions

How long does RNG certification take?

Testing timelines vary by laboratory and workload, but most RNG certifications for a single game or platform are completed within four to eight weeks, provided the technical documentation is complete at submission.

Do I need a new RNG certificate for every game?

In most cases, yes — each distinct game or RTP variant typically requires its own certification, although games built on an already-certified core RNG engine can sometimes be tested under an abbreviated process.

Which testing laboratories are most widely accepted by regulators?

GLI, iTech Labs, BMM Testlabs, eCOGRA and NMi are among the laboratories most widely recognised across MGA, UKGC, Isle of Man, Gibraltar, Kahnawake and other established licensing regimes, though the accepted list varies by jurisdiction.

Does RNG certification need to be renewed?

Yes. Most jurisdictions require periodic recertification, and any change to the RNG algorithm, seeding method or game math model will typically trigger a mandatory re-test regardless of the renewal schedule.

Can RUE recommend a specific testing laboratory?

Yes — we advise on the most suitable accredited laboratory for your target jurisdiction and game type, and manage the engagement on your behalf.
