Slots
We do not publish a slots catalogue yet. This page says what we would have to know first, and points you at the part of the same question we can already answer.
Why there is no list of slots here
The number every slots page leads with — “RTP 96.5%” — is not a property of the game. Studios certify a title in several configurations, commonly around 96%, 95% and 94%, and the casino chooses which one to run. Two casinos can offer the same slot, with the same name and the same artwork, and return different amounts over the same number of spins.
A catalogue that prints one RTP per game is therefore wrong at almost every casino that carries it — and it is wrong in the direction that flatters the operator, because the studio default is usually the highest of the certified settings. We would rather publish nothing than publish that number without saying where it applies.
So a slots section here waits on two things: a games source we are allowed to cite by name, and our own reading of the setting each licensed casino runs on the titles it carries. Until both exist, this page stays as it is.
What we can tell you today
Which studios each licensed casino actually carries is a fact we can read from the operator's own pages and date. Each studio below has its own page listing the licensed casinos that carry it, with the level of proof marked on every row — whether we catalogued the title in that lobby, counted the studio among the live tables, or are only repeating the operator's claim.
If you came here to work out what a bonus is really worth on slots, the wagering calculator answers that directly: it converts an offer into the turnover it demands and what that turnover costs at a given RTP.
Studios, and who carries them
Why this section has no game catalogue
Every large comparison site in this market carries thousands of slot pages — ten thousand at one competitor, twenty-two thousand at another. We carry none, and the reason is a data problem rather than an editorial choice.
A slot page is only worth reading if it states what the game returns, and the honest version of that figure has two halves: the range the studio ships, and the setting the casino you are about to play at actually runs. The first is obtainable. The second is published by nobody in this catalogue, which means a page presenting a single RTP figure would be presenting the studio default as though it were what you will get.
The commercial route into slot data is a licensed feed — the going rate is around ten dollars a month for a catalogue plus demo player — and every one of them requires a domain of our own to authorise the embed. Until this site has one, a slot section built on real data cannot exist, and a slot section built on copied data is exactly what we tell readers not to trust.
What we publish instead
The studio pages in this section list what each maker is known for and which casinos in our catalogue carry its games, labelled by how we know: a title we catalogued in that lobby, live tables we counted ourselves, or the operator's own claim and nothing more.
The reviews go further where an operator lets them. Where a casino publishes any return-to-player figure at all, the review records it with the date, and where a casino publishes nothing, the review says that too — because "no figure published" is itself the most useful fact available about what a lobby costs to play.
And the guide on RTP explains the mechanism in full: why the same slot can pay differently at two casinos, what volatility does that RTP does not, and where to find the number inside a game's information panel when an operator does publish it.
What a slot page will contain when we build one
The two numbers that describe any slot
Return to player is the long-run average return, and it is the price of playing: a 96% game keeps 4p of every pound staked. Volatility is how that return arrives — small and often, or rare and large. Both are properties of the game, both are published by the studio, and only one of them is ever advertised by a casino.
They interact in a way that catches people out. A high-volatility game at 96% can return almost nothing across an entire evening and still average 96% over millions of spins, because the average is carried by outcomes most sessions never see. The advertised figure is true and it is not a description of your Saturday.
The number that actually applies to you is the one in the game's own information panel at the casino you are playing at, because many studios ship a title at several RTP settings and the operator picks. Checking it takes ten seconds and it is the single most useful habit in this entire subject.
Britain also caps what can be staked on a single slot spin: £5 per game cycle for players aged 25 and over since 9 April 2025, and £2 for players aged 18 to 24 since 21 May 2025. Both limits are statutory and apply at every licensed operator, so no promotion or VIP tier can raise them.
That is why our rating method scores RTP transparency at six points and records the operator's configured figure separately from the studio default. A number that varies by casino cannot be published once and treated as universal.
