A game aggregator is a B2B software provider that sits between online casino operators and game studios. Instead of building and maintaining a separate integration with every studio, an operator integrates the aggregator once and gains access to the aggregator's whole catalogue โ often several thousand titles from dozens or hundreds of providers. The aggregator handles game launch, wallet transactions, reporting and, in many cases, certification and jurisdiction controls on the operator's behalf.
How it works
Each game studio hosts its titles on a remote game server (RGS). The aggregator integrates with every studio's RGS once and exposes a single API to operators. When a player opens a game, the operator's platform calls the aggregator, which launches the correct title from the studio's server and returns the game to the player's browser.
Money moves through a seamless wallet: the game asks the aggregator for a bet or a win, the aggregator relays it to the operator's wallet, and the balance updates in real time without the player leaving the game. Every round is logged, so the operator gets one consolidated report across all providers instead of one report per studio.
Commercially, the aggregator usually takes a share of gross gaming revenue (GGR) on top of the studio's own share, or charges a fixed platform fee. Contracts typically define which markets each title may be offered in, which is why aggregators maintain per-jurisdiction certification data for every game.
Why it matters for operators and suppliers
For operators, aggregation is the fastest route to a large lobby: one commercial agreement, one technical integration and one invoice. It also shifts certification tracking and version updates to the aggregator. The trade-off is margin โ the aggregator's fee sits between the operator and the studio โ and dependency on one supplier's uptime.
For game studios, an aggregator is distribution. A new studio with ten titles cannot sign and integrate a hundred operators directly; listing with two or three aggregators puts its games in front of that operator base at once. Established studios often run both models: direct integrations with large operators and aggregation for the long tail.
Example
An operator entering Ontario integrates one aggregator that already holds registration with the regulator and certification for 800 titles approved for the province. Launch takes weeks rather than the months needed to sign and integrate 20 studios individually. The operator pays the aggregator 3% of GGR on those games; the studios' own 8โ12% share is passed through in the same statement.
Frequently asked questions
A platform provider (PAM) runs the operator's player accounts, wallet, bonuses and back office. An aggregator supplies game content into that platform. Many platform providers include an aggregation layer, and many aggregators are integrated into several platforms.
Most aggregators charge a percentage of GGR, commonly in the low single digits, added to the studio's own revenue share. Some charge a fixed monthly platform fee or a minimum guarantee. Large operators negotiate lower rates in exchange for volume or exclusivity.
Often yes, for the handful of top studios whose titles drive most of the revenue, where a direct deal saves the aggregator margin. Aggregation then covers the rest of the catalogue.

More terminology

- Crash GamesCrash games are fast, simple casino games in which a multiplier rises from 1x until it randomly crashes; players win by cashing out before the crash.
- Geo-location & Geo-fencingGeo-location and geo-fencing are the checks that confirm where a player physically is, so an operator only accepts bets from jurisdictions where it is licensed.
- Hit FrequencyHit frequency is the percentage of game rounds that produce any win at all, regardless of size โ for example 25% means one spin in four pays something.
- Hold PercentageHold percentage is the share of total stakes an operator actually keeps over a period: GGR divided by turnover, the realised counterpart of house edge.
