Slots by Theme
On this page
Every game on this site is dressed as something. Fish, sweets, a pyramid, a wheel with a presenter standing beside it. The dressing is the first thing you see and the last thing that should decide what you play, because the theme is chosen by a marketing department and the way a game pays is chosen by a maths team.
That is the standard advice and it is nearly right. What it misses is that the two are not independent. Studios reuse mechanics inside a theme, so a theme ends up predicting a mechanic, and a mechanic really does decide how a game pays. Fishing slots almost all run a cash collection feature. Confectionery slots almost all tumble. Once you know that, the theme becomes a rough filter for the kind of session you are about to have.
What follows is what we found reading the games themselves. Every figure came off the game’s own rules screen or its own server, and where a studio does not publish something the table says so rather than borrowing a number from somewhere else.
A theme gets a page here when the games in it share something worth writing down, and not before. A shared colour palette is not enough. These are the ones that qualify so far.

What a theme actually predicts
Not the return to player. Across the slots read here the span runs from 96.06% to 96.71%, and the themes are scattered through it with no pattern worth reporting. The highest figure belongs to a fishing slot and the second highest to a confectionery slot. Two thirds of a percentage point separates the whole catalogue. Nobody picks a theme and gets a better RTP for it.

What a theme does predict, loosely, is the shape of the feature. Fishing means a collection mechanic: a symbol appears, and everything on screen carrying a printed value pays out at once. Confectionery means tumbling: winning symbols vanish, new ones drop, and the sequence continues while wins keep landing. Egypt means an expanding symbol locked in for the duration of a bonus. These are not rules, but they hold often enough that seeing the theme tells you roughly what the bonus round will feel like before you open the game.
And the theme predicts the ceiling, because the ceiling follows the mechanic. Maximum wins on this site run from 2,100x the bet to 25,000x, and that spread tracks the feature far more closely than it tracks the RTP. A collection game caps low, because its biggest prize is the value printed on one symbol. A tumbling game with multipliers caps high, because its biggest prize is a chain of them.
So the honest reading is this: the theme suggests a mechanic, the mechanic suggests a ceiling, and the ceiling tells you what sort of session to expect. The RTP will be much the same either way.
Theme by theme, with the figures
Fishing
The most directly comparable theme we have, because all three games run versions of one feature. That makes the differences between them unusually visible.
Big Bass Bonanza states a maximum win of 2,100x the bet, and its highest money symbol is worth 2,000x on its own. A single fish, collected once, is therefore almost everything the game can pay, and the rest of the paytable is arithmetic around the edge of it. That is not a criticism of the game. It is a description of where the ceiling comes from, and it is exactly the sort of thing a maximum win figure hides.
Fishin’ Frenzy reports 96.12%, which is the lowest of the three, and its Big Catch sequel reports 95.32%. Big Bass Crash states no return to player at all. It gives a bet range and a payout range and stops there, which for a game running on the same fishing furniture as the other two is worth noticing.

Sweets
Two Pragmatic Play games, both tumbling, both dressed in confectionery, and separated on RTP by seven hundredths of a percentage point. Sweet Bonanza reports 96.6% and Sugar Rush 1000 reports 96.53%. That difference is not a reason to choose either one and no player will ever feel it.
The ceilings are where they part company. Sweet Bonanza’s own rules screen gives a maximum of over 21,100x the bet. Sugar Rush 1000 states 25,000x. Both are numbers most sessions will never approach, but they describe genuinely different tails, and unlike the RTP gap the difference is real. The studio’s own volatility ratings follow the same split: medium for one, high for the other.
| Game | Studio | RTP we read | Max win stated |
|---|---|---|---|
| Sweet Bonanza | Pragmatic Play | 96.6% | Over 21,100x bet |
| Sugar Rush 1000 | Pragmatic Play | 96.53% | 25,000x bet |
Ancient Egypt
Egypt is the oldest theme in slots and the most reskinned, so the interesting question is not what these games look like. It is whether the number on the rules screen is a property of the game or a setting on somebody’s server.
Eye of Horus answers it. The game reports 96.31%, and it reports it under a configuration its own server labels the standard profile. A game only names the profile it is running when more than one profile exists. That is about as close to a written admission as you will get that the figure is a dial, and that the operator you play at may have it set somewhere else. Its Golden Tablet sequel reports 95.20%.
| Game | Studio | RTP we read | Max win stated |
|---|---|---|---|
| Eye of Horus | Merkur | 96.31% | Not stated |
Wildlife
Animal slots are usually Megaways games and Megaways games are usually sold on the ways count, which is the least interesting number on the screen. Buffalo King Megaways reports 96.52% and caps at 5,000x. Both ordinary.
What is not ordinary is its multiplier arithmetic. It multiplies its wild multipliers together, where Pragmatic Play’s own Sweet Bonanza adds them. Two games from one studio, opposite arithmetic, and the difference decides what a good sequence is actually worth. It is also unusually clear about its ante bet: where many games print a second RTP for the raised stake and leave you to work out what you bought, this one states what the extra stake buys on the same screen.
| Game | Studio | RTP we read | Max win stated |
|---|---|---|---|
| Buffalo King Megaways | Pragmatic Play | 96.52% | 5,000x bet |
Game shows
A live game show is not a slot with presenters, and the distinction that matters is what its RTP figure describes. Evolution publishes one number for Crazy Time: 96.08%. The game is eight different bets with eight different structures, and they cannot all return 96.08%. A player who only ever backs one segment is not playing the game that headline figure describes.
Evolution’s public page does not break the number down by bet type. The per bet returns exist in the game’s own paytable. We have not read them, so this site does not print them, and neither should anyone quoting a per bet figure they have not seen.
| Game | Studio | RTP we read | Max win stated |
|---|---|---|---|
| Crazy Time | Evolution | 96.08% | 20,000x in the Crazy Time bonus |
Where a theme misleads you
Twice now, reading across a theme has turned up something that reading one game would have missed.
The sequel returns less. Fishin’ Frenzy reports 96.12% and Big Catch reports 95.32%. Eye of Horus reports 96.31% and Golden Tablet reports 95.20%. Two different studios, two different themes, the same direction of travel, and in both cases nothing on the newer game tells you it is the worse deal. The sequel carries the name you already trust, which is the whole point of making it. Check the number on the sequel rather than assuming it inherited one.

The lookalike does different arithmetic. Sweet Bonanza and Buffalo King Megaways are both Pragmatic Play, both feature multipliers, and both are widely written up as though multipliers work the same way in each. They do not. One adds and one multiplies. If you are choosing between two games because they look like they play alike, the rules screen is the only place that will tell you whether they do.
Three multipliers land in one sequence. What the win gets multiplied by depends entirely on which game you are in.
What each game actually tells you
Before any of the advice above is worth acting on, it is worth knowing how often a studio answers the question at all. Three figures a player would reasonably expect a game to state, checked against every game on this site.

The gaps cluster by studio, not by theme. Every game here that states all three figures is a Pragmatic Play slot. Both Merkur games state a return to player and a volatility rating but no maximum win at all, which across two games looks like house style rather than an oversight. And the two formats that are not slots state least of anything on the site: Big Bass Crash gives only a maximum, and 20p Boost Roulette gives none of the three.
That is worth carrying into any game you open. Studios are consistent with themselves, so if one of them has left a figure out of the game you are looking at, it has probably left the same figure out of the rest of its catalogue too.
Choosing a theme for the session you want
If you want a long session with frequent small returns, the collection themes are the closer fit. Fishing games concentrate their pay into a bonus that lands reasonably often and pays modestly when it does, and their ceilings are low enough to say so honestly: 2,100x on Big Bass Bonanza is the whole game.
If you want a short session with a real tail, the tumbling themes are built for it. Sweet Bonanza and Sugar Rush 1000 cap at over 21,100x and 25,000x, and their base game is correspondingly quieter. The studio’s own volatility rating is the fastest signal here and it is printed on the rules screen of every game we have opened.
If you want to know exactly what you are staking before you start, avoid the games that do not tell you. Two of the games on this site state no RTP anywhere in the client. That is legal, it is not unusual, and it is a fact about the game worth weighing.
One thing no theme will do is change the arithmetic. Every game here is designed to return less than it takes, and the theme is the part of it that has no bearing on that at all.

Common questions
Does the theme of a slot affect its RTP?
No. Across the slots read here the RTP span is 96.06% to 96.71% and the themes are distributed through it at random. Theme correlates loosely with mechanic, and mechanic correlates with maximum win, but neither moves the return to player.
Why are there only a few themes?
Because a theme only gets a page once there is something to say about the games inside it. We would rather have five theme pages carrying findings than twenty-five carrying a sentence each and a list.
Where do the RTP figures on this page come from?
Each one was read off the game itself, on its own rules screen or from its own server, and dated on the review it came from. None was copied from another site. Where a game does not state a figure, these tables say “not stated” instead of filling the gap.
Why does an RTP here differ from the one my casino shows?
Because some games ship in more than one configuration and the operator chooses which to run. Eye of Horus reports its figure under a profile its own server calls the standard one, which implies others exist. Always check the rules screen inside the client you are actually playing.
Are the demos on these pages free?
Yes. They are the studios’ own free play builds, loaded straight from the studio, using play money with no cash value. There is no account, no deposit, nothing to win and nothing to lose. We are not paid to feature any of them.
