Play'n GO casinos
Book-style slots with an expanding symbol chosen at the start of the bonus round.
Play'n GO built its position on one structure and refined it for years: ten free spins, one symbol picked at random before they begin, that symbol expanding to fill a reel whenever it lands. Book of Dead is the version most lobbies carry, and once you recognise the shape you will see it across half the studio's catalogue under different artwork.
The rule, not our mood
A casino appears here when we hold evidence it carries Play'n GO games — a title of theirs catalogued in its lobby, their name in the live-table count we recorded, or the operator's own published studio list. Every row says which of the three it is, and the order is our 100-point score, not the strength of the evidence.

Live table counts are ours, recorded per casino with a date; capacity varies through the week, so a count is a snapshot rather than a constant. An em dash means we hold no count for that operator, not that it has none.
The book format, and what it does to a session
The bonus round is decided by a single random draw. If the expanding symbol is a high-paying one, ten spins can produce a very large result; if it is the lowest card symbol, the same ten spins are close to worthless. There is no skill element and no way to influence the draw, which makes the format unusually swingy for a game that looks conventional on the base reels.
That distribution matters when a bonus is attached. A game whose value is concentrated in a rare, high-variance event is a slow way to clear wagering and a fast way to lose a balance, and operators know it — book titles are frequently excluded from bonus play or weighted below 100%, which means spins on them count for less than the terms' headline figure implies.
Check the game weighting table in the bonus terms before assuming any of this list applies to your balance. It is usually a separate page from the offer itself, and it is where the difference between a 35x requirement and a practically unclearable one tends to live.
Three ways a casino can "have" a studio, and why we keep them apart
Every affiliate site publishes a list of studios under each casino. Almost none of them says where that list came from, and the three possible answers are worth very different amounts.
The strongest is a title we hold: a specific game, catalogued by us, recorded in that casino's lobby. It is checkable in a minute — open the lobby, search the name. The middle tier is a live-dealer count: we recorded how many live tables the casino runs and which studios supply them, which is solid for live content and says nothing about slots. The weakest is the operator's own studio list, copied from its site. It is not worthless — an operator has little reason to invent a supplier — but it is a marketing page, it goes stale, and it routinely names studios whose games have quietly disappeared from the lobby.
Sites that blend all three into one badge row are not lying so much as declining to distinguish. We print the tier on every row because the difference decides what you should do next: verify a title yourself, or take the claim at face value and check the lobby before you deposit.
The same game is not the same game at every casino
A studio builds a game with a return-to-player figure, and for many titles it builds several — the same slot shipped in a 96.5% version and a 94% one, sometimes a 92% one, and the operator picks. The name, the artwork and the maths of the bonus round are identical. The long-run return is not.
This is why a studio page is not a shortcut to a good session. Knowing that a casino carries a studio tells you nothing about which configuration of its games that casino runs. Where an operator publishes the setting, or where a payout report names it, we record it on that casino's review — and it is worth points on our rubric precisely because so few operators will say.
The practical move is to read the figure inside the game itself rather than on any list, including ours. Most slots show their RTP in the information panel, and that panel reflects the build the casino is running rather than the studio's headline number.
How to check a lobby yourself in two minutes
Nothing on this page needs to be taken on trust. Casino lobbies are searchable and filterable, and the check is faster than reading a review of it.
- Open the casino's game lobby and filter by provider. If the studio is not in the filter list, the casino does not carry it today, whatever any page says.
- Search for one title you know the studio makes. A studio present in the filter but with an empty result is usually a lobby that has been half-migrated.
- Open the game and read the RTP in its information panel. Compare it with the studio's published figure — a gap is the operator's choice, not an error.
- Check the licence separately, on the public register, by domain. A first-rate studio in the lobby of an unlicensed site buys you nothing when a withdrawal goes wrong.
What a studio can and cannot tell you about a casino
A recognisable studio is weak positive evidence about an operator. Major studios do license their content selectively, and a lobby full of names you have heard of means someone signed a contract and passed a compliance check. That is a floor, not a recommendation.
It says nothing about the things that decide how a casino feels to use: how fast it pays, whether its bonus terms have a maximum cashout hidden in clause fourteen, whether support answers at eleven at night, whether its licence is real and current. Those are measured separately, and they are what the score in the list above is made of.
It also says nothing about exclusivity. Studios supply hundreds of operators at once; a game you enjoyed at one casino is very likely available at forty others, several of which pay faster. The studio is a reason to look at a casino, never a reason to stay at a bad one.
