Studios build several versions of the same title and the operator selects one, so the figure that applies is the one published in that game’s own information panel here rather than a number quoted anywhere else.

Game Providers — Every Studio at Slots99
Casinos do not make their own slots. Specialist studios build them, license them out, and the same title appears at dozens of operators, which is why you meet Sweet Bonanza everywhere you go. What actually differs between one casino and the next is which studios it carries, and that is a more useful thing to browse by than most people realise.
More than 20 studios supply the lobby here, covering both the slots side and the live tables. You must be 18 or over to play.
The studios most people arrive looking for
Pragmatic Play is the largest presence on the site by a wide margin and the only studio here supplying both slots and live dealer tables. If you have played an online slot in the last few years, you have played one of theirs.
NetEnt built much of the template everyone else now works in, and its games remain the most readable in the lobby: clear symbols, uncluttered screens and mechanics you can follow without a manual. Red Tiger runs a deep catalogue in the same tradition with a harder edge to the maths.
Big Time Gaming matters out of proportion to its catalogue size, because it invented the Megaways engine that a large part of the industry now licenses. If you like the format, this is where it came from.
Where the volatility lives
Nolimit City and Hacksaw Gaming are the two studios worth approaching deliberately rather than by accident. Both build games with long dry spells, brutal variance and a top end that justifies the wait, and both have a devoted following for exactly that reason. Anyone who dislikes sitting through a hundred spins of nothing should browse elsewhere on purpose.
At the other end, Spinomenal, Wazdan and Endorphina run large catalogues of steadier games, which also makes them the sensible pool for clearing a bonus.
The rest of the roster
Relax Gaming, Microgaming, WorldMatch, SlotMatrix, Red Rake, Fantasma Games, ReelPlay, ELK Studios and BF Games fill out the catalogue. On the live side, Evolution supplies the majority of the tables in the live casino and effectively defined the live dealer format.
Why browsing by studio works
Studios have house styles the way film directors do. The thing you liked about a game is usually a habit of the people who made it rather than a one-off decision, so if one title landed for you, that studio's catalogue is a far better hit rate than the lobby at random.
Every studio page here filters the catalogue to that developer, and nearly every game inside opens in demo mode without an account or a deposit. Browsing a studio you have never tried costs nothing at all, which makes it the cheapest experiment on the site. If you would rather sort by theme than by maker, the collections do that instead, and All Slots filters the whole catalogue by provider, volatility and features at once.
Nearly every slot in the lobby opens in demo mode with no account and no deposit. Live dealer tables are the exception, because a real dealer is dealing real cards.
Pragmatic Play, by a wide margin, and it is also the only one supplying both slots and live tables. Spinomenal and Red Tiger follow with large catalogues of their own.
Because the studio licenses it out. What differs between operators is which studios they carry, which bonuses apply, and which games count toward wagering.
Eligibility is set per game, not per studio. Games inside Bonus Play count; the bonus conditions are the authority.
