How do I verify that an online casino's published RTP figures are based on real independent audits?

RTP figures are one of those things that look precise but can be almost meaningless without the right context — so it's worth understanding exactly what a real audit trail looks like and how to spot it.

What "independently audited" actually means

An RTP percentage published on a game's help page is, at base, a theoretical figure calculated from the game's math model. What gives that number credibility is certification by an Independent Testing Laboratory (ITL) — a specialist firm that reverse-engineers the game's random number generator and probability model, then confirms the stated return matches what the math actually produces. This is not a casino doing its own homework; it's an outside body with no financial stake in the outcome.

In Ontario's regulated market, this isn't optional. Games and random number generators must be certified against the Registrar's Standards for Internet Gaming by an ITL registered by the AGCO before they can be deployed in the regulated Ontario market. The AGCO publishes a list of labs approved to issue those certifications. That list currently includes BMM North America, Eclipse Compliance Testing, eCOGRA, Gaming Associates Europe, Gaming Laboratories International, and Global Lab Ltd., among others. These are internationally recognized testing bodies — names you can look up directly on the AGCO's site to confirm their standing.

How to verify it yourself

There are a few concrete things to check:

• Look for the ITL badge or certificate link. Reputable operators display the logo of whichever lab certified their games — eCOGRA, GLI, BMM, and similar — usually in the site footer or within individual game information panels. Many also link to a live certificate or a published audit report. If you can click through to a dated certificate on the lab's own domain, that's the real thing.
• Check that the RTP is game-specific, not a blanket claim. A trustworthy operator publishes per-game or per-variant RTPs, not a single vague number covering the whole library. A slot certified at 96.1% and a blackjack variant certified at 99.5% are meaningfully different figures — a site that lumps them together is obscuring information, not sharing it.
• Confirm the operator is on the official registry. A directory of all fully registered and authorized operators and their igaming sites is available via the iGaming Ontario website. Regulated Ontario sites also display both the iGaming Ontario logo and the BetGuard logo — per iGaming Ontario, those two logos together tell you the site is managed by iGaming Ontario and regulated by the AGCO. If those logos are absent, stop there.
• Understand what the audit covers. An ITL certification confirms the game's theoretical RTP and that the RNG produces genuinely random outcomes. It does not certify the operator's actual payout history over a given month — that's a different, operator-side reporting matter. Some operators voluntarily publish periodic actual payout reports; those are a bonus, but the ITL certification is the foundational piece.

The structural guarantee Ontario players have

Key components of igaming systems — including games and random number generators — must be certified against the Registrar's Standards before deployment, and the AGCO does not directly test or approve igaming technology through its own in-house gaming laboratory — meaning the certification work falls to those registered third-party ITLs, whose independence from both the operator and the regulator is the whole point. Beyond game-level certification, all registered internet gaming operators are also required to submit an independently audited assessment of the processes and controls they have in place to meet the Registrar's Standards for Internet Gaming. So there are two layers: the game itself is ITL-certified, and the operator's broader control environment is separately audited.

The practical upshot for an Ottawa player: if you're on a fully registered Ontario site, the RTP figures for its games have gone through a structured certification process before you ever saw them. The ITL badge in the footer isn't decoration. If you want to dig deeper on any specific game, the operator's help section or the ITL's own published certificate database is the place to look — not a third-party review site.
