We have reviewed 43 slots and 9 house, crash and live game-show titles. Every RTP and volatility figure we hold for them is on this page. The number that matters most is not the highest one: 15 of those 43 slots ship with more than one RTP, and the casino — not the studio — picks which version you play. On nine of them a specific reduced figure is documented. Cash Bandits is the worst case we found: a 97.5% default that some operators run at 91%, which turns an expected loss of $25 per $1,000 wagered into $90.
Last updated 4 September 2026. Every figure below comes from our own review of that specific game, not from a supplier feed. Where a figure is not published by the studio, we say so instead of estimating.
The slots where your casino chooses the RTP
Studios licence many games in several RTP builds. Same name, same artwork, same features, different maths — and the operator selects the build when it installs the game. This is legal, disclosed in the game’s own info panel, and almost never mentioned in the lists that rank these slots by RTP.
These nine have a specific lower figure on record. The last column is arithmetic, not a forecast: it is what the house expects to keep from $1,000 of wagering at each build.
| Slot | Provider | Default / high build | Lowest documented build | Expected loss per $1,000 wagered |
|---|---|---|---|---|
| Cash Bandits | RTG | ~97.5% | 91% | $25 → $90 |
| Achilles | RTG | ~97% build exists; 95% is the default | 91% | $30 → $90 |
| Scary Rich | Rival Gaming | 96.70% | 92.52% | $33 → $74.80 |
| Milk the Cash Cow | Rival Gaming | 98.70% | 94.90% | $13 → $51 |
| Grand Luxe | Nucleus Gaming | 97.53% listed | 94% | $24.70 → $60 |
| Starlight Princess 1000 | Pragmatic Play | 96.5% | 94% | $35 → $60 |
| No Limit Bandit | Nucleus Gaming | ~96.92% catalogue-high | 95% | $30.80 → $50 |
| High Noon | Nucleus Gaming | 97.03% | 95.4% | $29.70 → $46 |
| Bubble Bubble | RTG | 96.3% | 95% | $37 → $50 |
Six more are flagged as operator-configurable in our reviews without a specific reduced figure on record. Treat the number as a ceiling, not a promise:
| Slot | Provider | Default RTP |
|---|---|---|
| Diamond Reels | Dragon Gaming | 97.45% (the studio’s highest) |
| Caesar’s Empire | RTG | ~97% |
| Thunderstruck II | Microgaming | 96.65% |
| Sweet Bonanza 1000 | Pragmatic Play | 96.53% |
| Gates of Olympus 1000 | Pragmatic Play | 96.5% |
| Twin Dragons | Dragon Gaming | 96.12% |
How to check which build you are playing
It takes about twenty seconds and it is the single most valuable habit on this page.
- Open the game and load the paytable or info panel — the i icon, or the menu in the bottom corner.
- Scroll to the last screen. The RTP is stated there, by law in every licensed jurisdiction and by studio policy nearly everywhere else.
- Compare it with the figure in our table. A match means you have the full build.
- If it is materially lower, you are on a reduced build. The game is not broken and the casino is not cheating — it has simply chosen the version that keeps more. Play that title somewhere else.
If the info panel states no RTP at all, that in itself is the answer to whether the operator wants you comparing.
All 43 slots we review, by RTP
Sorted highest to lowest on the default figure. The reducible column marks the fifteen games above. Where a studio has never published volatility or a max win, the cell says so — we would rather leave a hole than fill it with a plausible number.

| Mega Moolah | Microgaming | 88.12% | Medium | Progressive (record £13.2M) | — |
That is 43 rows and two omissions worth naming: The Party Guy is the only game where we hold an RTP but the studio publishes neither volatility nor a max win, and Book of Darkness is the only review that never states its RTP in the body text even though the figure is on record.
Mega Moolah at 88.12% is not a mistake
It is eight full points below everything else on the table, and it is correct. Progressive jackpot slots divert part of every wager into the shared pool, so the RTP you experience on the reels is deliberately low. The pool eventually pays — Mega Moolah holds a record £13.2 million win — but it pays one person, once, and the missing eight points are what fund it. If you are playing for entertainment across a long session, a progressive is the most expensive way to do it. If you are buying a lottery ticket and you know that is what you are doing, the maths is not a trick.
Volatility matters more than the last decimal of RTP
The gap between 96.51% and 96.53% is noise. The gap between Starburst at low volatility with a 500x ceiling and San Quentin xWays at Nolimit City’s “insane” rating with a 150,000x ceiling is the difference between two entirely different activities — and the two sit within 0.06 points of each other on RTP.
Read the table in that order. RTP tells you the long-run cost. Volatility and max win together tell you the shape of the ride: a 500x ceiling means the money comes back in small pieces and a balance drifts down slowly. A 150,000x ceiling means almost every session ends at zero and the mathematics is carried by outcomes you will probably never see. Nine of the games here have ceilings above 20,000x. On those, a 96% RTP is an average across a distribution you personally are not going to experience.
The nine titles that are not slots
We file these under slots on the site for navigation, but they do not belong in the table above, and mixing them in is how other lists end up putting a 99% RTP game at the top of a slot ranking. Their maths works differently: on the Stake originals you set the risk yourself, and on crash games your exit point is a decision rather than a spin outcome.
| Game | Type | Provider | RTP | Note |
|---|---|---|---|---|
| Stake Dice | House game | Stake | 99% | 1% edge, fixed at every setting |
| Mines | House game | Stake | 99% | You set the mine count from 1 to 24 |
| Plinko | House game | Stake | 99% | Risk level and row count are yours to pick |
| Aviator | Crash | Spribe | 97% | $10,000 cash cap per bet |
| JetX | Crash | SmartSoft Gaming | ~97% | Spec range 96.2–98.9%, operator-configurable |
| Spaceman | Crash | Pragmatic Play | 96.56% | Cash cap varies by casino |
| Dream Catcher | Live game show | Evolution | 96.58% | The cleanest of the wheel shows |
| Monopoly Live | Live game show | Evolution | 96.23% top-line | Lower on the bonus bets |
| Crazy Time | Live game show | Evolution | 96.08% top-line | 94.41–96.08% by bet; average ~95.41% |
Two of these deserve a flag. Crazy Time is quoted at 96.08% almost everywhere, but that is the best bet on the layout; across the bets people actually place the average is nearer 95.41%, and the bonus segments are the weakest of them. JetX is the only game on this page with a published operator-configurable range rather than a build list — anywhere from 96.2% to 98.9% — so the figure in front of you is the only one that counts.
What we left out, and why
Five games have two RTP figures in circulation and are deliberately not in the reducible tables, because the second figure is not an operator switch:
- A Night in Paris — 96.92% standard against 96.5% for the jackpot edition. A different build sold as a different product, not a version of the same one.
- Dead or Alive 2 — 96.8% against 96.82%. Rounding.
- As the Reels Turn — ~96.94% against ~95%. Sources disagree and Rival has never published a figure. We do not know which is right, so we will not present the gap as a reduction.
- The Slotfather — ~95% against one source at 95.69%. Same problem, smaller gap.
- Screaming Chillis — 96.57% default against trackers quoting up to ~97.08%. The disagreement points upward, which is not the risk this page is about.
We also do not publish a “hit frequency” column. The figures circulating for these games come from player-logged spin samples rather than studio disclosure, and a few thousand spins on a high-volatility slot tells you almost nothing about how often it really pays. A column of numbers we cannot stand behind would make this page look more complete and be worth less.
And the obvious limit: this is every slot we have reviewed, not every slot in existence. The highest-RTP games in the world — Ugga Bugga at 99.07%, Book of 99, Mega Joker — are mostly European titles that US-facing offshore casinos do not carry. We cover those separately in highest RTP slots 2026, including where availability breaks down by casino family.
The Monkey’s Verdict
Chasing the top of this table is the wrong use of it. The spread between the best and the worst genuine slot here, setting the progressive aside, is 98.70% down to 95%: on $1,000 of wagering that is $13 against $50. Real money, but not life-changing money — and it is dwarfed by the thing almost nobody checks.
Because the same Cash Bandits at two different casinos is $25 against $90, a bigger swing than picking the best slot on this page instead of the worst. The highest-value habit is not selecting a game from a ranking. It is opening the info panel of whatever you were going to play anyway, reading the RTP the casino actually installed, and walking away when it does not match. That takes twenty seconds and beats every list on the internet, including this one.
If the numbers on this page are starting to feel like a system rather than the cost of an evening’s entertainment, that is worth noticing.

Frequently Asked Questions
What is the highest RTP slot you review?
Milk the Cash Cow by Rival Gaming, at a 98.70% default - and it is also the clearest warning on the page, because a reduced 94.90% build is documented at some casinos. Setting the reducible titles aside, Diamond Reels by Dragon Gaming at 97.45% is the highest figure we hold. Three Stake house games run at 99%, but dice, mines and plinko are not slots and we keep them in a separate table rather than putting them at the top of a slot ranking.
Can the same slot have a different RTP at different casinos?
Yes, and it applies to 15 of the 43 slots we review. Studios licence many games in several RTP builds and the operator picks one when it installs the game. Cash Bandits is the sharpest example: a 97.5% default that some casinos run at 91%. On $1,000 of wagering that is the difference between an expected loss of $25 and one of $90. The version you are on is always stated in the game's info panel.
How do I check the RTP of a slot before I play it?
Open the game, load the paytable or info panel - the i icon, or the menu in the bottom corner - and scroll to the last screen. The RTP is stated there. Compare it with our table: a match means you have the full build, and a figure well below it means the casino has installed a reduced version, so play that title somewhere else. If the info panel gives no RTP at all, that tells you something too.
Why is Mega Moolah only 88.12%?
Because it is a progressive jackpot slot, and part of every wager is diverted into the shared pool instead of being paid back on the reels. The pool does pay - Mega Moolah holds a record 13.2 million pound win - but it pays one person once, and those missing eight points are what fund it. For a long entertainment session a progressive is the most expensive choice on the table. As a lottery ticket you understand you are buying, the maths is not a trick.
What is a good RTP for a slot?
96% or higher is good, 97% and up is excellent, and 98% and up is rare. Almost everything we review sits between 95% and 97%, so the spread between the best and worst genuine slot on our list is about $37 per $1,000 wagered. That is real but modest, which is why the reducible-build question matters more than the ranking: choosing the wrong casino for one game can cost more than choosing the worst game on the page.
Is a high RTP more important than volatility?
No, and Starburst against San Quentin xWays proves it. They are within 0.06 points of each other on RTP, but Starburst is low volatility with a 500x ceiling and San Quentin is rated insane with a 150,000x ceiling. RTP tells you the long-run cost; volatility and max win tell you the shape of the ride. On the nine games here with ceilings above 20,000x, the quoted RTP is an average across outcomes you will most likely never see.
Do you publish hit frequency?
No. The hit-frequency figures circulating for these games come from player-logged spin samples rather than studio disclosure, and a few thousand spins on a high-volatility slot says almost nothing about how often it really pays. We would rather leave the column out than fill it with numbers we cannot stand behind.
