Slots by numbers: which published figures actually vary
The return figures read off the games themselves cluster inside two thirds of a percentage point once the slots are taken on their own. Over the same games the maximum win varies by close to twelve times. One of those numbers separates games and the other does not.
On this page
Every slot arrives with a small set of published numbers: a return to player, a volatility word, a maximum win, a stake range and a layout. They are printed on the rules screen, repeated on the studio’s site, and copied across listing pages until they read like a specification.
They are not equally informative. We have now read twenty-two return figures off the games themselves, and every slot among them fits inside two thirds of a percentage point. Over the twenty-one games that state a maximum win, the ceiling varies by close to twelve times. One of those numbers separates games and the other does not, and the one that does not is the one every site puts in the headline.
This page takes the five numbers in turn and says what each is worth. Every figure below was read off a game’s own rules screen or its own server and is dated on the review it came from.

That is every return to player we have read. The slots occupy a startlingly narrow band, 96.06% to 96.71%, and the two figures sitting well below them are crash games rather than slots, which is a point we come back to. On a £100 stake played through, the difference between the top of that chart and the bottom is sixty five pence in theoretical return. Studios compete on the second decimal place of a figure that describes the long run, and a session is not the long run.
The two figures below the band
Two returns on that chart sit well under everything else, and both belong to crash games rather than slots. Spaceman and Big Bass Crash each state 95.50%, more than half a point below the lowest slot we have read.
They are the same engine in different artwork, which is the likeliest explanation for the identical figure. What makes the pair worth pointing at is the company they keep: Aviator, in the same genre, publishes 97%. That is a spread of one and a half percentage points across three crash games, against two thirds of a point across every slot on this site.
So the format that looks the most uniform from outside, one rising line and one decision, is the one where the published price varies most. If you are going to check a number before playing anything, check it on a crash game.
Return to player, and what it does not promise
RTP is the proportion of everything staked that a game is built to pay back across millions of spins. It is a property of the maths, verified before the game is licensed, and it is real. It just does not describe an evening.
Three things about it are worth more than the figure itself.
Some games have more than one. Big Bass Vegas Double Down Deluxe prints four separate return figures on its own rules screen: normal play, the ante bet, the bought round and the bought super round. They all read 96.50%, but the game had to state four to say so, and the sites that quote it quote one. Two other games in our set print an ante figure one hundredth below their base figure, which the features page sets out in full.
Operators can run a different one. Studios ship some titles in more than one configuration and a casino picks. The figure on a listing page is a figure from somewhere, not necessarily from the game you are about to open.
It is not a schedule. A 96.71% game is not due to pay and never becomes due. There is no counter, and the phrase covers a very long run of spins rather than the next hundred.
Volatility, which is a word and not a measurement
Volatility is meant to fill the gap RTP leaves: how the return arrives, in small regular amounts or in rare large ones. Studios publish it as a word, chosen by them, against no published scale.
Here is every label we have been given, with the returns of the games filed under it.
- Low96.06% to 96.51%
- Medium96.12% to 96.71%
- Medium-high96.31%
- High96.5% to 97%
The bands overlap, and one of the overlaps is instructive. 96.71% appears under High and under Medium, on two games from the same studio in the same family. Big Bass Christmas Bash is rated High and Big Bass Splash is rated Medium, and both state 96.71%.
We had a tidier finding before we read the seventh game in that family. With four games in hand the pattern looked like a ladder: both 96.71% games rated High, both 96.0x games rated Low, cheaper games flatter. Splash broke it. What survives is weaker and still useful: every game rated Low in our set sits in the 96.0x band, and the reverse does not hold. A Low label predicts a low figure. A low figure predicts nothing.
Low is also the only band on that chart that does not overlap another, which is the strongest thing anyone can say for the word.
The maximum win, which is the number that actually varies
Stated maximum wins across the same set, on a logarithmic scale because 2,100x and 25,000x do not share a linear axis usefully.
Nearly twelve times separates the two ends. This is the published figure with real range in it, and it is the one presented as a headline rather than as a specification.
Two things to hold on to. First, a maximum win is a stopping rule, not a target. Every Big Bass game we have read states that if a free spins round reaches the cap, the round ends immediately, the win is paid and the remaining spins are forfeited. Second, the ceiling does not follow the return, and inside one family the two run in opposite directions:
| Game | Return | Ceiling |
|---|---|---|
| Big Bass Bonanza | 96.71%, the joint highest of any slot here | 2,100x, the joint lowest |
| Big Bass Halloween | 96.06%, the lowest of any slot here | 2,100x, the joint lowest |
| Big Bass Day at the Races | 96.07% | 10,000x, the highest in the family |
The game returning the most stops soonest. The game returning one hundredth more than the lowest reaches nearly five times further. Whatever the ceiling is measuring, it is not generosity.
What each game will let you stake
The number nobody publishes on a listing page, and the one that decides whether a game is playable at the amount you actually want to play at.
- Chicken Road0.01 to 1,000,000.00
- Fishin' Frenzy0.20 to 400.00
- Big Bass Amazon Xtreme0.10 to 375.00
- Big Bass Vegas Double Down Deluxe0.10 to 375.00
- Big Bass Christmas Bash0.10 to 375.00
- Big Bass Day at the Races0.10 to 375.00
- Big Bass Halloween0.10 to 375.00
- Starlight Princess 10000.20 to 300.00
- Sweet Bonanza Super Scatter0.20 to 300.00
- Buffalo King Megaways0.20 to 300.00
- Sweet Bonanza0.20 to 300.00
- Big Bass Splash0.10 to 250.00
- Big Bass Bonanza0.10 to 250.00
- Sugar Rush 10000.20 to 240.00
- Spaceman1.00 to 100.00
- Big Bass Crash1.00 to 100.00
- Eye of Horus0.10 to 100.00
Maximum stake varies fourfold across our set, from 100 to 400 in the demo build’s own units, and it varies inside a single family: Big Bass Splash stops at 250 where five of its siblings go to 375. Minimums cluster at 0.10 and 0.20 and are the least interesting figure on this page, which is why they are also the one most often quoted.
Reels, rows and how a game pays
Layout is the number that sounds technical and predicts the least. What matters is the last column: whether wins are found on lines, on ways, in clusters, or anywhere on the grid.
| Game | Reels | Rows | How it pays |
|---|---|---|---|
| Buffalo King Megaways | 6 | Not stated | Up to 200,704 ways |
| Eye of Horus The Golden Tablet Megaways | 6 | 2–5 | Up to 15,625 Megaways |
| Le Pharaoh | 6 | 5 | 19 fixed lines |
| Big Bass Amazon Xtreme | 5 | 3 | 10 |
| Big Bass Bonanza | 5 | Not stated | 10 fixed lines |
| Big Bass Christmas Bash | 5 | 3 | 10 |
| Big Bass Day at the Races | 5 | 3 | 10 |
| Big Bass Halloween | 5 | 3 | 10 |
| Big Bass Splash | 5 | 3 | 10 |
| Big Bass Vegas Double Down Deluxe | 5 | 3 | 10 |
| Eye of Horus | 5 | Not stated | 10 fixed lines |
| Fishin' Frenzy | 5 | Not stated | 10 fixed lines |
| Fishin' Frenzy Even Bigger Catch | 5 | 3 | 10 fixed lines |
| Fishin' Frenzy The Big Catch | 5 | 3 | 10 fixed lines |
| Fishin' Frenzy The Big Splash | 5 | 3 | 10 fixed lines |
| Rocket Reels | 7 | 7 | Cluster pays, 5+ matching |
| Starlight Princess 1000 | 6 | 5 | Pay anywhere, 8+ symbols |
| Sugar Rush 1000 | 7 | 7 | Cluster pays, 5+ connected |
| Sweet Bonanza | 6 | 5 | Pays anywhere, 8+ symbols |
| Sweet Bonanza Super Scatter | 6 | 5 | Pay anywhere, 8+ symbols |
Ten fixed lines is not an old-fashioned choice, it is a different one. Eye of Horus runs ten lines, no tumble and no expanding grid, and returns 96.31%, ahead of the 200,704-way game in the same table. The ways figure is the largest number on this site and one of the least informative.
Where the studio and the game disagree
We read every figure twice where we can: once on the game’s own rules screen, once on the studio’s own website. They almost always match. Once so far, they did not.
| Game | Studio website | The game itself | Agrees |
|---|---|---|---|
| Big Bass Halloween | 96.04% | 96.06% | No, two hundredths apart |
| Big Bass Day at the Races | 96.07% | 96.07% | Yes |
| Big Bass Christmas Bash | 96.71% | 96.71% | Yes |
| Big Bass Bonanza | 96.71% | 96.71% | Yes |
Both figures were read on 21 August 2026 and both are screenshotted. Two hundredths of a percentage point changes nothing about how the game plays. It changes something about how much weight a number deserves when it has been copied from a marketing page rather than read off the game, which is the reason this site exists.

Common questions
What is a good RTP for a slot?
The question assumes more range than exists. Every slot on this site states a return between 95.32% and 96.71%, and the sixty five hundredths between them is not what will decide how an evening goes. Across all twenty-nine games the band widens to 95.32% to 99.00%, but the figures at either edge of it belong to crash games rather than slots. Volatility and the maximum win describe the shape of a session far better, and neither is published as precisely.
Does high volatility mean bigger wins?
It means less frequent ones, which is not the same claim. The largest ceiling we have read, 25,000x on Sugar Rush 1000, is on a game rated High. The second largest, above 21,100x on Sweet Bonanza, is on a game rated Medium, and a different game rated High is capped at 5,000x. The word is chosen by the studio against no published scale and it is best read as a rough description of rhythm rather than of size.
Where do these figures come from?
Each one was read off the game’s own rules screen inside the studio’s free demo build, or off its own server, and dated on the review it came from. None was copied from another listing site. Where a game does not state something, the tables here say so rather than filling the gap.
Why do some games show more than one RTP?
Because they behave differently depending on how you stake. An ante bet and a bought round are separate configurations of the same game, and a studio that is being thorough prints a figure for each. Big Bass Vegas Double Down Deluxe prints four. Most sites quote the first and ignore the rest.
Can a casino change a game’s RTP?
An operator cannot rewrite a game, but a studio may ship more than one configuration of a title, and the operator chooses which to run. The reliable figure is the one on the rules screen of the game in front of you, which takes about thirty seconds to check and settles the question for that session.
