Highest Win Rate Guarantee: Verifying It on Your Own
Reviewed by Top Paying Online Casinos Editorial Team · Last updated · Testing methodology · Affiliate disclosure · Independent checks for players in Canada.
Plenty of casinos tell you their games are generous and leave it there. A claim you cannot test is just a slogan. The Highest Win Rate Guarantee is different because the thing it promises, the top RTP build of each title, is printed inside the game. This page shows how to read it, what to compare it with and what to do when something does not line up.
How most casinos handle the question, and why it falls short
The usual approach is a banner. "Fair games", "great payouts", sometimes a blended percentage covering the whole lobby. A blended figure hides everything that matters, because it mixes a 96% slot with a table game and a video poker title that follows different rules.
What you actually need is the number for the game you are about to play. That number exists. It sits in the information screen, and the guarantee is built around it rather than around a lobby-wide average.
The commitment in full
Here is what the operator commits to, in its own words.
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.
The sentence worth underlining is the one about selecting the highest available version. A promise like that can be tested title by title, and unlike a vague claim it can be shown wrong. That exposure is the whole reason it is worth taking seriously.
A test you can run in about two minutes
Pick a slot. Open its information or paytable screen and write down the stated RTP. Find the studio's own published figures for the same title; Pragmatic Play and Games Global both document their games. Put the two side by side.
If the in-game number matches the studio's highest published version, the guarantee holds for that title. Repeat on three or four more, ideally across different studios and different volatility levels. A single match proves little; a run of matches is informative. Jot the titles and figures down as you go, so that you are comparing notes and not memories.
Where a title was released at several builds, this is the ladder you would be comparing against.
| RTP version of the same slot | House edge | Approx. spins from $100 at $1/spin |
|---|---|---|
| Lower build | 7.94% | ~1,260 |
| Mid build | 5.80% | ~1,725 |
| Highest build — guaranteed here | 3.29% | ~3,040 |
If a figure does not match
Do not assume bad faith, and do not assume it is a mistake either. Screenshot the information screen, note the title and date, and ask support to explain which version is running. Then tell us, because we want our reviews to reflect what you find.

Mobile Play and Support: Your Questions
Answers here cover these licensed online casinos, including the 96% slot floor, not every provincial monopoly.
Most questions here come from people playing on a phone, so we start with those.
What number should I expect to see on a slot?
We look for 96%+ on slots built to the highest available version. A noticeably lower figure on a title that the studio also publishes at a higher level is the thing to question.
Does the test work for video poker?
Yes, though the variable is the paytable rather than a studio build. A full-pay schedule makes up to 99.9% possible with correct play. A reduced schedule lowers it, and the screen shows which one you are on.
What about blackjack?
Read the payout line on the table. A natural should pay 3:2, not 6:5. That one detail moves the house edge more than most players expect.
Is the guarantee backed by a regulator?
The brands we rank are licensed by the Kahnawake Gaming Commission, and the group carries the eCOGRA Safe and Fair seal. The licence register is at gamingcommission.ca. The guarantee itself is the operator's commitment.
Can I test it without spending money?
Reading the information screen costs nothing, and most lobbies let you open a game before you stake anything. Whatever you do, keep within the limits you set and stay 18+.
