Casino marketing tosses around phrases like “98% RTP” and “highest payout casino” as if they’re self-explanatory. They’re not. We asked an iGaming expert to decode what these numbers actually mean for players.
The online casino space runs on claims. Log into almost any comparison site and you’ll be met with payout percentages, RTP badges, and assurances that recommended platforms return more than their competitors. Most players take these figures at face value, but the terminology is slippery, and the numbers mean different things depending on who’s using them.
We spoke with Nikolina Jeric, an iGaming expert with close to a decade of experience reviewing online casinos and payment systems for some of the industry’s leading comparison platforms, including Casino.ca. She has seen how these concepts get stretched in marketing and has a practitioner’s view of what the numbers are actually telling you.
There’s a lot of language around payouts: RTP, payout rate, house edge. Are these all measuring the same thing?
Nikolina Jeric: These are three separate concepts that get blurred together. The first is a game’s RTP (Return to Player), a theoretical figure built into the game‘s programming. It describes the percentage of bets that a game is designed to return over a very large number of rounds. A 96% RTP slot is built to pay back 96 cents per dollar wagered across millions of spins. The second concept is house edge, which is just the inverse: a 96% RTP means a 4% edge for the house.
The third, and usually the most useful, is a casino’s overall payout rate. That’s a historical figure based on results, measuring what the casino paid out as a percentage of total wagers across all its games over a set period. Those are meaningfully different things. RTP is what a game is designed to do. A payout rate is what a casino actually did.
What determines why one casino’s payout rate ends up higher than another’s?
Nikolina Jeric: The game library is probably the biggest factor. A platform where most players gravitate toward blackjack and video poker will have a higher average payout rate than one dominated by lower-return slots, because the underlying game mathematics pull the overall figure up or down. That’s essentially a reflection of what casino players choose to play, rather than a reflection of the casino’s generosity.
The measurement period matters a lot too. Monthly figures can be skewed by a handful of large jackpot wins or a quiet stretch. Annual rates, calculated across far more bets, give a much more reliable picture of what a casino returns. And then there’s whether the figure’s been independently verified. A self-reported payout rate and an audited one from an accredited testing lab aren’t the same thing, even when the numbers look similar.
When a casino advertises a high payout rate, what should players actually check?
Nikolina Jeric: Start with where the number comes from. Is it independently audited, or is the casino just saying it about itself? Platforms carrying an eCOGRA seal or a certificate from a lab like iTech Labs have had their results checked by an organisation with no stake in the outcome.
Then look at the time period. A 98% payout rate measured over one month isn’t the same claim as one measured over a full year. If a casino doesn’t say which, that should also tell you something. Same goes for coverage: does the figure include the whole platform or just certain product categories? Some casinos are transparent about this, while others aren’t. You can only draw useful comparisons if you know you’re looking at equivalent data.
Does it actually matter which casino a player chooses, or is most of it determined by which games they pick?
Nikolina Jeric: Both matter, but casino selection gets underestimated. A casino that builds its library around strong-value titles gives players a better environment than one that fills the lobby with whatever returns the highest margin. Most players assume a slot’s RTP is fixed by the developer and identical everywhere, but that’s not usually how it works. Many games ship with multiple RTP configurations, and the operator chooses which to activate. The same slot can run at 96% at one casino and 92% at another, and there’s usually nothing in the lobby to tell you which version you’re on. That makes choosing the right casino a much bigger variable than most players account for.
Bonus terms are worth thinking about too. A high published payout rate doesn’t help much if the bonus on your account carries a 60x wagering requirement that makes withdrawing your winnings close to impossible in practice. The headline rate and the real experience of getting money out are two separate things, and players who only look at one of them tend to get caught out.
Where should Canadian players go to find payout data they can actually trust?
Nikolina Jeric: Comparison platforms that test casinos directly, rather than passing on what operators report about themselves. Casino.ca is where I’d point Canadian players. I contribute to the site, and the team independently tests and verifies payout rates rather than taking operator figures at face value. The methodology for identifying the best paying online casino options in Canada is based on real testing data, which gives players something they can actually use to compare. Audit seals from eCOGRA or iTech Labs are worth looking for on any casino too. Self-reported figures with no audit trail, headline percentages with no stated methodology; that’s the data that deserves scepticism, however confident the claim sounds.
Thanks, Nikolina. Sounds like the only figure worth trusting is one that’s been verified by someone outside the casino.
