The brand on the casino’s door didn’t make the games. A separate layer of B2B suppliers did — and that layer is where the industry’s real concentration sits.
The online gambling industry presents itself to the public as a set of consumer brands: casinos with names, logos and advertising budgets. Underneath, it runs on a supply chain that almost no player could name, and which is considerably more concentrated than the shop-front suggests.
Casinos are, for the most part, retailers. They hold the licence, take the deposits, run the marketing and own the customer relationship. What they overwhelmingly do not do is build games. Those come from specialist studios, licensed in and paid a share of the revenue they generate.
The practical consequence is that two casino brands competing hard for the same customer are frequently selling identical products.
Three layers, not one
The chain runs roughly as follows.
Studios design and build the games and hold the intellectual property. They rarely deal with players directly and often have no consumer-facing brand at all.
Aggregators sit in the middle, holding integrations with hundreds of studios on one side and hundreds of operators on the other. Their existence is what makes it economically feasible for a mid-sized casino to offer 4,000 titles: it integrates once with the aggregator rather than 200 times with individual studios.
Operators hold the gambling licence, run the site and take the bets.
Revenue flows back down the chain. The studio typically receives a percentage of the net revenue its games produce, with the aggregator taking a cut for the plumbing.
The studios worth knowing
A handful of European names account for a large share of what appears in a typical lobby. Sweden’s NetEnt and Play’n GO, Malta’s Pragmatic Play, Britain’s Blueprint Gaming and Eyecon, Austria’s Greentube — and, across southern and eastern Europe in particular, Bulgaria’s Euro Games Technology, whose online catalogue runs under the Amusnet and EGT Digital brands.
Availability is not universal, which is the part players consistently get wrong. A studio’s games appear only where that studio has a commercial agreement and the necessary market certifications. This is why a title a player recognises from one casino is simply absent at another, and why marketing claims about game libraries deserve checking rather than trusting — sites tracking egt casinos online have documented operators advertising a studio’s availability that turns out not to hold when the lobby is actually searched.
Why concentration matters
The supply chain’s shape has consequences that reach past trivia.
Product differentiation is largely illusory. If two operators license from the same studios through the same aggregator, they are selling the same games at the same mathematics. Competition therefore happens on bonuses, payout speed, support quality and interface — not on the product itself.
Certification is concentrated too. A small number of testing laboratories certify the random number generators and verify published RTP figures for most of the market. That concentration is efficient, and it also means a great deal of consumer protection rests on very few institutions.
Studios are more exposed to regulation than operators. A licensing regime that bans a mechanic — autoplay, or bonus-buy features, both restricted in several European markets — forces studios to build separate compliant versions per jurisdiction. That cost pushes towards consolidation, which pushes towards further concentration.
| Layer | Role | Paid by | Player-facing? |
| Studio | Builds the games | Revenue share | Logo only |
| Aggregator | Distribution and integration | Cut of studio revenue | Invisible |
| Operator | Licence, deposits, marketing | Player losses | Yes — the brand |
How to see the supply chain from the lobby
The structure is invisible in the marketing but perfectly legible from the product, if you know where to look.
Every game carries its studio’s branding on the loading screen and in the information panel. Most lobbies expose a provider filter listing every studio the operator carries. Reading that filter tells you more about an operator’s product than any promotional page — a long list of well-regarded studios indicates real integration work and a platform capable of supporting it; a short list padded with unfamiliar names usually indicates a single aggregator deal taken as a block.
The aggregator layer is harder to see, because it deliberately does not brand itself to players. The tell is usually consistency: operators sharing an aggregator tend to carry near-identical studio line-ups, including the obscure ones. Where two supposedly unrelated casinos offer the same unusual set of small studios, they are almost certainly buying from the same distributor.
Where the money actually goes
It is worth being concrete about the economics, because the split explains a good deal of behaviour.
Of the revenue a slot generates — the amount players lose, not the amount they stake — the studio typically takes a share running to a modest fraction, with the aggregator taking a cut of that. The operator retains the remainder, out of which come marketing, payment processing, licensing fees, taxation and compliance.
The important consequence is that the studio’s incentive is volume of play rather than depth of loss for any individual. A studio earns from a game being played widely; it has no interest in any particular player losing heavily. The operator’s economics work differently, which is why player-protection regulation is aimed at operators rather than studios, and why the two layers behave differently under scrutiny.
What it means for anyone comparing casinos
Two conclusions follow, and both are useful.
The first is that comparing operators on game selection is mostly comparing marketing copy. Beyond a certain library size, the meaningful differences are elsewhere: which regulator issued the licence, how quickly withdrawals actually complete, what the terms permit while a bonus is active, and whether complaints get resolved.
The second is that a studio’s presence tells you nothing about an operator’s trustworthiness. Studios license broadly. A well-regarded studio’s games appearing on a site is a fact about a commercial agreement, not an endorsement of the operator — and it should never be read as one.
