The Highest Win Rate Guarantee™ Explained
Reviewed by Certified Casinos Editorial Team · Last updated · Testing methodology · Affiliate disclosure · Independent checks of certified online casinos in Canada.
The Highest Win Rate Guarantee™ sounds like marketing, but it is a concrete, measurable commitment — and it is why these casinos top our list.
The Highest Win Rate Guarantee™ commits Luxury Casino to serving the highest-RTP build of each title its software providers release — 96%+ on slots, where the same game other casinos run at 92% or 94%, and up to 99.9% on video poker where the full-pay schedule is live. Game studios often ship multiple RTP (Return to Player) versions; when an operator picks a lower build, the house edge rises and your bankroll dies faster. Luxury Casino does the opposite: it always selects the highest available version, so the house takes a lower margin per spin and you get more spins and longer sessions from the same stake. RTP is a long-run statistical measure, not a promise of winning any single session.
Why the RTP version matters
Many slots ship in several RTP (Return to Player) versions — for example 91.8%, 94.1% or 96.37%+. The game looks and plays identically; only the maths underneath changes. Some casinos quietly deploy the lower version to widen their margin. Under the guarantee, the Casino Rewards brands always run the highest available build, so the exact same title returns more to you over time.
| RTP version of the same slot | House edge | Approx. spins from $100 at $2/spin |
|---|---|---|
| Lower build | 8.20% | ~610 |
| Mid build | 5.90% | ~845 |
| Highest build — guaranteed here | 3.63% | ~1,375 |
The difference compounds over a session: choosing the 96.37% version over the 91.8% one adds roughly 765 extra spins to a $100 bankroll at $2 per spin — before variance even enters the picture.
A concrete example
Say two casinos both offer the same popular slot. One runs the 91.8% build, the other — under this guarantee — runs the 96.37% build. Play the same session on each and, on average, the higher build hands back more of every wager, so your money survives longer and you get more shots at the game’s features. We break the full maths down in our RTP guide.
How to check the RTP version yourself
You do not have to take any casino at its word. Most providers publish RTP in the game itself:
- Open the game and find the information or paytable menu (often an “i”, a burger menu or “Rules”).
- Scroll to the “Return to Player” or “RTP” line — reputable studios such as Pragmatic Play and Games Global (formerly Microgaming) state it there.
- Compare the figure to the provider’s published maximum for that title. If it reads 96%+ where the studio’s top build is 96%+, you are on the highest version.
- Cross-check that the games are eCOGRA-audited — independent testing confirms the stated RTP is what actually runs.
Common myths
“Higher RTP means I will win.” It does not. RTP lowers the long-run house edge; it never promises a winning session. Variance still rules any single visit.
“A big welcome bonus beats a higher RTP.” Rarely, once you read the wagering terms. Value compounds through RTP on every spin; a bonus is a one-off with strings attached.
“All casinos run the same RTP.” They do not. Studios ship multiple builds of a title, and operators choose which to deploy — the guarantee is the promise to always choose the highest.
What the guarantee does not promise
The guarantee is about game configuration, not individual results. A higher RTP lowers the house edge and stretches your bankroll, but it is not a promise of winning and outcomes always vary. Play for entertainment, set deposit and loss limits before you start, and treat any bonus as secondary.

Frequently asked questions
Answers to common questions from Canadian players — including legality, RTP and VIP status match.
Is the Highest Win Rate Guarantee™ just marketing?
No — it is a configuration promise, not a slogan. It means the highest available RTP build of each game — 96%+ on slots, up to 99.9% on video poker — is the one that runs, which is measurable in the game’s own paytable and confirmed by eCOGRA audits.
Is a bigger welcome bonus not better than a higher RTP?
Usually not, once you read the terms. A large bonus with steep wagering and a lower-RTP game library is worse long-term value than a smaller headline on the highest-RTP builds. Value lives in the RTP, not the headline.
Does a higher RTP mean I will win?
No. RTP is a long-run average measured over many thousands of spins. A higher RTP lowers the house edge and stretches your bankroll, but any single session can win or lose. It changes the odds, not the outcome.
Does the guarantee apply to table games too?
Yes. Blackjack is paid at 3:2, not the 6:5 you see on many tables, and table RTP sits in the same high band as slots under the group configuration.
