Casino Software Providers: Who Actually Builds the Games

Open two online casinos side by side and the lobbies will look nothing alike. Different colours, different navigation, different names above the door. Then start opening games and the same titles appear in both, because neither casino built any of them.

The operator licenses the games, arranges them and takes a cut of the turnover. The software comes from a fairly small group of studios, most of which you have never heard of and several of which now belong to each other. Once you can read the provider name in a game’s info panel, a lot of marketing stops working on you.

Why the Studio Behind a Game Matters to You

Three reasons, and only one of them is about quality.

The first is that two casinos running the same studios are, for practical purposes, running the same casino. If both carry Evolution live tables and the Pragmatic Play slot catalogue, the games are not what separates them. Payout speed, licensing and terms are. Choosing between them on “game selection” when the selections overlap by eighty percent is choosing on nothing.

The second is that studios have house styles, and those styles are about volatility rather than polish. Nolimit City and Hacksaw Gaming build games designed to take your money for two hundred spins and then hand back a large multiple; Play’n GO and NetEnt sit far closer to the middle. Neither approach is better, but discovering the difference by accident with real money is an expensive way to learn it.

The third is the one almost nobody writes about, and it is the reason this page exists at all: the same game can ship at several different RTP settings, and the operator chooses which one you get.

The Same Game, Six Different Payback Rates

A studio does not build one version of a slot. It builds one game with a set of configurable maths models, and licenses them to operators as a menu. Blueprint, Play’n GO, Pragmatic Play and others all publish multiple configurations of popular titles, and the spread between the best and worst version of the same game is commonly four to six percentage points.

That is enormous. A game at 96.2% and the identical-looking game at 91.5% share artwork, sounds, bonus rounds and name. The reels look the same because they are the same. The only visible difference is a number in the information panel, which is precisely why you should read it before your first spin at any operator you have not used before.

The UK Gambling Commission’s rules effectively force operators to surface the figure, which is why UK-facing lobbies almost always show it in the game info panel. Elsewhere it is voluntary, and an operator that publishes RTP per title without being made to is telling you something real about how it does business. That single behaviour correlates better with a casino being good to deal with than any welcome bonus does.

The Studios Behind the Lobbies

Every studio in this table appears in at least one casino we have reviewed, and the last column is taken directly from those reviews rather than from a marketing page.

A note on Evolution, because the name comes up constantly. It began as a live-dealer company and still dominates that category so completely that most players have never sat at a live table run by anyone else. Then it went shopping.

NetEnt in 2020, which brought Red Tiger with it. Big Time Gaming in 2021, which is the studio that invented the Megaways engine now licensed across hundreds of other studios’ games. Nolimit City in 2022. Add Ezugi from 2018 and one company owns the live floor, the biggest slot mechanic of the last decade and several of the most recognisable slot brands in the business.

Whether that concentration is bad for players is genuinely arguable. It has certainly not made the live product worse. It does mean that “we offer games from over sixty providers” is a much emptier claim than it sounds, because a good number of those sixty answer to the same board.

Who Actually Runs the Live Tables

Live dealer is a physical business, which makes it different from slots in a way worth understanding. Somebody has to build a studio, employ dealers in shifts, run cameras and encode video around the clock. That is a capital and staffing problem, not a software problem, and it is why the field is small.

Evolution operates studios across Europe, North America and Asia, including dedicated rooms built and branded for individual operators. Playtech runs its own live operation at meaningful scale. Ezugi, now inside Evolution, specialises in tables built for specific regional markets. Pragmatic Play entered later and has grown quickly.

When a casino advertises “exclusive live tables”, what it has usually bought is a branded room inside somebody else’s studio, with its own dealers and its own table limits. That is a real thing rather than pure marketing, and it typically means better-staffed tables at peak hours. It does not mean the operator built anything.

The Labs That Check the Maths

No licensed game reaches a lobby without independent certification, and three names do most of that work.

The independent testing houses

Lab	Founded	What it certifies
Gaming Laboratories International (GLI)	1989	RNG behaviour, game maths and platform integrity across most US and international jurisdictions
eCOGRA	2003	Game fairness, published payout percentages and operator conduct standards
iTech Labs	2004	RNG certification and RTP verification, widely used across European and Australian markets

What certification actually guarantees is narrower than most players assume. It confirms the random number generator is properly random and that the game pays back what its own paytable claims. It does not mean the game is generous, and it does not mean the operator selected the generous configuration of it. Fair and favourable are different words.

How to Check Who Made a Game and What It Pays

Thirty seconds of work, and it is the single most useful habit on this entire site.

1. Open the game and find the information button, usually an “i” or a burger menu in the corner of the game frame, not the casino’s own page around it.
2. Read the paytable’s final screen. Studio name, game version and, in most regulated markets, the theoretical return to player.
3. Compare that RTP against the studio’s published figure for the title. A meaningful gap means the operator licensed a lower-paying configuration.
4. Check the volatility rating if one is given. It will not change the cost, but it tells you whether your balance is likely to bleed slowly or vanish and occasionally rebound.

If an operator makes any of that hard to find, treat it as information. There is no technical reason to hide a figure the regulator already made you calculate.

Casinos and the Studios They Carry

Each review in our register lists the studios behind that operator’s lobby, so you can see the overlap for yourself before choosing between two brands that look different and are not.
