Every online casino lives or dies by its game lobby. Players expect familiar slots, live dealer tables, crash games and new releases every week. Getting those games onto your site one studio at a time is slow and expensive to maintain. That is the problem a casino game aggregator solves.
This guide explains what an aggregator is, how the technology works, and how to compare partners so you pick one that still fits when your casino is bigger.
What is a casino game aggregator?
A game aggregator is a company that has already integrated many game studios and exposes all of them to operators through one API. Instead of signing and building separate integrations with each provider, the operator integrates once and gets access to a single catalogue.
In practice the aggregator sits between your platform and the studios:
- Your platform handles players, accounts, payments and the lobby.
- The aggregator handles game launches, round data and the connection to each studio.
- The studios run the game servers and the maths behind each title.
When a player opens a game, your platform asks the aggregator for a launch URL. Bets and wins then flow back to your wallet in real time. You see every round in one format, regardless of which studio made the game.
At Velocis Gaming our game aggregation gives operators access to 150+ providers through one integration.
How the integration works
Most aggregators follow the same basic pattern. The details matter, so it is worth understanding them before you compare offers.
Seamless wallet vs transfer wallet
With a seamless wallet, the player's balance stays in your system. The aggregator calls your wallet endpoints for every bet, win and refund. Players see one balance across slots, live casino and sportsbook, which is what most of them now expect.
With a transfer wallet, money moves into a separate balance at the game side and back again. It is simpler to start with, but players notice the friction, and reconciliation becomes harder as you grow.
For a new casino, seamless wallet is the usual choice. Our API integration page shows what the calls look like.
Launch, callbacks and round history
A typical flow looks like this:
- Your lobby requests a game list with metadata (provider, type, thumbnails, supported currencies).
- The player clicks a game and your platform requests a launch URL for that session.
- The game sends bet and win callbacks to your wallet; you answer with the new balance.
- Every round is stored with an ID so support and finance can trace it later.
Good aggregators make retries, idempotency and rollbacks predictable. That is where a lot of hidden support work comes from, so ask about it directly.
Aggregator vs direct integrations
Direct integration with a studio can make sense for a very large operator that wants custom commercial terms or exclusive content. For almost everyone else, aggregation wins on time and effort:
- One technical integration instead of one per studio
- One contract and one invoice for the content side
- One reporting format for finance and compliance
- New studios added without new development on your side
The trade-off is that you depend on the aggregator's uptime, support and commercial relationships. That is why choosing the right partner matters more than the size of the logo wall.
How to choose a game aggregator: a checklist
Use these questions in your first calls. The answers tell you more than any brochure.
1. Catalogue fit for your markets
A big catalogue only helps if the right games are available where your players are. Ask:
- Which providers are available for my target countries?
- Are there studios that restrict certain markets or currencies?
- Which crypto currencies are supported per studio, if you plan a crypto casino?
- How quickly are new releases added to the catalogue?
Look at the mix as well as the count: slots, live casino, crash and instant games, table games and virtual sports. Browse our providers list for an idea of what a broad catalogue covers.
2. Integration quality
Ask for the API documentation before you sign. Check whether it covers:
- Clear wallet callback specs with error codes
- Idempotent transactions and documented retry behaviour
- A staging environment with test games
- Round history and replay links for support
If the documentation is thin, integration will be slow, whatever the sales deck promises.
3. Back office and reporting
Your team will live in the aggregator's reporting every day. You want game-level and provider-level reports, filters by currency and market, and exports your finance team can use without manual work. Ask for a demo with real screens, not slides.
4. Lobby tools
Some aggregators give you only an API. Others also provide game metadata, categories, tags and images that make your lobby easier to build and keep fresh. Ask what is included and how often metadata is updated.
5. Support and uptime
Games break at night and at weekends. Ask:
- What are the support hours and channels?
- Is there a named technical contact during integration?
- How are provider outages communicated?
6. Commercial model and contract terms
Commercial terms vary between partners and markets, so compare them on equal footing: what is included, how billing is calculated, and what happens when you add new markets. Read the contract for exclusivity clauses and notice periods. Ask your own legal adviser to review it.
7. Licensing and compliance
Studios need to know where their games are offered. Your aggregator will ask for your licence and target markets. If you do not have a licence yet, ask whether they can point you to licensing support. Rules vary by country and change often, so take local legal advice.
Aggregator or turnkey platform?
An aggregator gives you games. A casino also needs player accounts, payments, bonuses, KYC tools, a back office and a front end. If you already run a platform, aggregation is the missing piece. If you are starting from zero, a turnkey casino platform includes the platform and the game catalogue together.
We compare both routes in our guide to launching an online casino: turnkey vs aggregation.
Common mistakes
- Choosing by catalogue size alone. Market availability and integration quality matter more.
- Skipping the staging test. Test bets, wins, rollbacks and network errors before launch.
- Ignoring currency support. Especially for crypto, check each studio.
- Forgetting the lobby. Great games in a poor lobby still underperform.
Summary
A casino game aggregator turns dozens of integrations into one. The best partner for you is the one whose catalogue fits your markets, whose API is well documented, and whose team answers when something breaks. Ask the questions above, test in staging, and keep your own legal and commercial advisers involved.

FAQ
What does a casino game aggregator do?
It connects many game studios to your casino through one API, so you integrate once and offer games from all of them in a single lobby with one wallet.
Do I need a licence to work with an aggregator?
Most studios require operators to hold a gaming licence for the markets they serve. Requirements vary by country, so take local legal advice.
How long does an aggregator integration take?
It depends on your platform and team. A well-documented seamless wallet API and a staging environment shorten the work considerably.
Can I use an aggregator with a crypto casino?
Yes, if the studios you need support your coins. Check currency support per provider before you plan your lobby.
