How do I confirm that the RNG used in an Ontario online casino game is genuinely random?

Random number generators in online casino games are one of those things that almost every player wonders about but few dig into — and in Ontario's regulated market, there's actually a meaningful answer grounded in enforceable technical standards, not just marketing claims.

What the AGCO actually requires of RNGs

The AGCO registers and regulates online gambling sites and sets standards to protect players while working to ensure game integrity — and its Registrar's Standards for Internet Gaming are specifically designed to ensure that game integrity protections are in place. The RNG requirements within those standards are detailed and demanding.

The random source and its outputs must pass applicable statistical tests of randomness and demonstrate unpredictability — and crucially, the random source must not be capable of being influenced by any means, including by the amount bet, style or method of play, or play history. That last point matters: the RNG cannot be "hot" or "cold" based on your session, your bet size, or anything else that happens at the table.

All software-based RNGs must be cryptographically strong, meaning that given an initial state or a sequence of past values, it must be computationally impossible to predict or estimate future values — and the RNG must periodically modify its state through use of an external source of entropy. In plain terms, even someone who knew the algorithm couldn't reverse-engineer upcoming results. Gaming devices must also not alter any function based on the actual hold percentage — so the game cannot quietly adjust its behaviour to hit a revenue target at your expense.

Gaming devices must be able to determine if there is statistical evidence that an RNG is not performing as expected for the game in question, and appropriately communicate this — meaning the system is expected to flag its own anomalies, not just pass a one-time test.

Since gambling is inherently risky and outcomes are never predictable, it's worth remembering that these rules exist to guarantee fairness, not to change the odds in your favour. If you're 19+ and playing in Ontario, ConnexOntario (1-866-531-2600) is there if you ever need support.

Independent testing labs: the verification layer that actually matters to players

The technical standards above are the rules — but who checks compliance? Suppliers must have their technology certified by a registered independent testing laboratory (ITL) before it can go live on any Ontario site. There are currently multiple ITLs registered with the AGCO. These are specialist firms — companies like eCOGRA, GLI, BMM, and iTech Labs are common in regulated markets globally — whose entire job is running the statistical analyses and source-code reviews that confirm an RNG behaves as required.

The assessments performed by the AGCO's own Gaming Lab involve statistical analysis of data sets with millions of data points to verify the randomness of both hardware and software RNGs used to determine game outcomes — which are central to game integrity. So the scrutiny happens at multiple levels: the ITL certifies the software supplier, and the AGCO's lab maintains its own testing capability on top of that.

Operators and gaming-related suppliers who run a gaming system must provide the AGCO with confirmation that their technology is compliant with all applicable AGCO standards and requirements. That confirmation has to be in place before the site goes live.

How you, as a player in Ottawa, can verify you're on a site where this applies

None of the above protections apply to offshore or unregistered sites — they only bind operators who have gone through Ontario's registration process. Being a fully registered and authorized operator in the Ontario igaming market means the organization has successfully received a registration from the AGCO and executed an operating agreement with iGaming Ontario — and to complete those steps, these organizations will have met rigorous standards of game integrity, fairness, player protections, and social responsibility.

The practical check for Ottawa players is straightforward: look for the iGaming Ontario logo on the site. The iGaming Ontario logo, wherever you see it, is a sign that you're playing on a site being conducted and managed by iGaming Ontario, offering player protections and meeting Ontario's high standards for game integrity and responsible gambling. Regulated Ontario sites also display the BetGuard logo — BetGuard being Ontario's centralized self-exclusion service, launched in May 2026, through which any 19+ player can opt out of all licensed operators in a single step. All igaming operators in Ontario participate in BetGuard. Both logos together are a reliable signal that the RNG rules above actually apply to the games you're playing.

For the definitive list of which operators are currently registered, a directory of all fully registered and authorized operators and their igaming sites is available via the iGaming Ontario website — that's the live source of truth, since the list updates as new operators are approved.
