The Highest Win Rate Guarantee™ Explained
Reviewed by Player-Tested Casinos Canada Editorial Team · Last updated · Testing methodology · Affiliate disclosure · Independent checks of tested 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 (typically 96% to 99.9%) of each slot its software providers release — the same title other casinos may run at 92% or 94%. 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 92.06%, 94.1% or 96.5%+. 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 $1/spin |
|---|---|---|
| Lower build | 7.94% | ~1,260 |
| Mid build | 5.90% | ~1,695 |
| Highest build — guaranteed here | 3.50% | ~2,855 |
The difference compounds over a session: choosing the 96.5% version over the 92.06% one adds roughly 1,595 extra spins to a $100 bankroll at $1 per spin — before variance even enters the picture.
A concrete example
Picture the identical slot at two casinos: a 92.06% version and the guaranteed 96.5% version. Nothing on screen differs, but over a long session the higher build keeps a larger share of your stake in play — that is the entire edge you are choosing when you pick a guaranteed-RTP brand. We break the full maths down in our RTP guide.
How to check the RTP version yourself
RTP is not hidden if you know where to look — it is usually one or two taps away in the game client:
- 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.
What people get wrong
“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.

Player-Tested Casinos Canada — Your Questions
Practical answers for Canadian players who want to verify a casino's claims before depositing rather than accepting them on trust.
Is the Highest Win Rate Guarantee™ just marketing?
No — it is a configuration promise, not a slogan. It means the highest available RTP build (96% to 99.9%) of each game is the one that runs, which is measurable in the game’s own paytable and confirmed by eCOGRA audits.
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.
Which studios supply these games?
Primarily Pragmatic Play and Games Global (formerly Microgaming). Both publish RTP figures per title, so the guaranteed “highest build” claim is verifiable rather than a black box.
