Connecting games to your online casino platform is one of the most critical decisions. And most operators face massive confusion when it comes to choosing. Should you integrate games with a Remote Gaming Server (RGS) or should you use a casino game aggregator that offers access to thousands of games via single API integration?

At first glance, they may seem like the same thing, but there is a huge difference when it comes to advantages, limitations, technical requirements and costs.

The choice also impacts how quickly you launch, how many games you can offer to your players, which markets you can enter, how much control you get to have over the platform, and how much you need to spend.

RGS vs aggregator? Which one aligns with your goals?

In this comprehensive guide, we’ll uncover how each model works along with factors that impact your business. Whether you are an operator, entrepreneur or you run an established casino business, this guide will help you make an informed decision.

What Is an RGS (Remote Gaming Server)?

A Remote Gaming Server (RGS) is a backend system that powers casino games. It is responsible for running game logic, processing player actions, generating outcomes, calculating payouts, and sending the results back to the casino platform.

How an RGS Works

When a player clicks on the play button, the casino platform sends a secure request to the RGS. The RGS then:

  • Verifies all the critical information
  • Runs the game as per built-in rules
  • Uses a random number generator (RNG) along with mathematical algorithms to generate an outcome
  • Calculates winnings
  • Updates player’s wallet balance
  • Sends the result back to the casino website or mobile app
    All these processes take place instantly, ensuring seamless user experiences.

Who Uses an RGS?

RGS integrations are commonly used by:

  • Businesses developing custom casino solutions
  • Gaming studios
  • Casino operators with their casino platform
  • Large operators managing multiple brands
  • Operators working directly with individual game studios

What Is a Casino Game Aggregator?

A casino game aggregator is a platform that offers multiple games from multiple gaming studios via single API integration. Instead of connecting your platform separately to every provider of your choice, operators integrate once and gain access to a large portfolio of games from multiple providers.

1

How a Casino Game Aggregator Works

  1. Game providers connect their RGS to the aggregator.
    The aggregator certifies for target markets and manages content from various game studios.
  2. The casino operator connects the casino platform with the aggregator via a single API.
  3. Players can access games from various game providers without the operator needing a separate connection to each one.

Casino game aggregation allpows operators to expand their game library much more quickly as compared to individual integrations.

2

Who Uses a Game Aggregator?

  • New online casinos
  • Operators looking to launch quickly
  • Turnkey and White-label casino platforms
  • Businesses that want access to thousands of games quickly
  • Operators with limited technical resources and budget

Both models offer access to hundreds and thousands of games. But they differ in integration process, technical complexity, data access, and long-term flexibility, and many more factors.

RGS vs Aggregator: Key Differences

1

Content Source and Game Library Size

An RGS integration allows you access to one gaming studio’s gaming content. If you want access to games from five gaming studios, you are looking at five separate integrations along with five certification processes.

On the other hand, a casino game aggregator offers you access to thousands of games from multiple gaming studios quickly through one single API integration.

RGS is a better option if you want better control. But if you want to launch games quickly, aggregation is a better fit.

2

Integration Effort and Regulatory Certification

Integration and development is only a part of the bigger picture. But when it comes to certifications, that’s where it gets tricky.

Every RGS connection you’ll use will require independent certification from every jurisdiction your casino is operating in. This often stretches the launch timeline, making it a less appealing option for operators who want to launch quickly.

A game aggregator usually completes this process for you, which helps you cut down time-to-market drastically.

3

Commercial Contracts and Billing

RGS integration requires you to sign separate agreements with every studio. This translates to separate invoices, contracts, terms and conditions and so on.

With an aggregator, you deal with only one partner, which helps you simplify the whole process.

4

Cost and Revenue Share

Though pricing varies based on your provider, your requirements and the market, it’s influenced by the below factors:

Direct RGS integrations may involve:

  • One-time integration as well as certification fees
  • Revenue-sharing agreements
  • Monthly platform fees
  • Game licensing fees

Aggregators may involve:

  • Integration/onboarding fees
  • Revenue share (sometimes layered — the aggregator’s cut plus each studio’s cut)
  • Monthly subscription or platform access fees

It’s important to point out that an aggregator significantly reduces development cost and long-term investment.

5

Customization, RTP Configuration, and Support

RGS offers direct integrations, which also offers you better flexibility:

  • Earlier access to new releases
  • Custom feature requests
  • Ability to select or negotiate RTP in some jurisdictions
  • Closer long-term business relationships
  • Direct technical support from the studio

Though aggregators do not offer this level of flexibility, they do offer greater convenience. Aggregators offer a single point of contact for support, onboarding, and platform management, also a non-negotiable game configuration.

6

Latency and Operational Resilience

A direct integration offers you better speed and performance while aggregator might cause some latency as aggregator acts as an additional layer. Think of this scenario, if an aggregator experiences an outage, every studio becomes inaccessible. Direct integration via RGS minimizes that risk as every provider is connected via a different RGS.

RGS vs Aggregator: Side-by-Side Comparison

Feature Remote Gaming Server (RGS) Game Aggregator
Game access Games from one studio per direct integration Games from diverse studios
Integration Separate integration per studio Single API integration for many studios
Certification Certificate required per-studio and per-jurisdiction Largely handled by aggregator
Time to launch Usually longer Quick
Technical effort Higher Lower
Customization / RTP control Better flexibility Less flexibility
Resilience Risk isolated per studio Aggregator outages can affect all connected studios
Support Directly from the studio Via aggregator
Contracts Multiple studio contracts Usually one commercial contract
Scalability Rebuilds but incremental Quick expansion
Best suited for Operators wanting control and customizations Operators prioritizing speed and simplicity

What are Some Pros and Cons of Using an RGS

1

Advantages

  • Direct relationship with the studio
  • Potential early access to new releases
  • Greater control over integration and RTP configuration
  • Access to player and game data
  • Risk isolated to a single provider if something breaks
2

Cons

  • Separate integration and certification per studio
  • Multiple commercial agreements to manage
  • More development and compliance overhead
  • Higher technical and regulatory complexity
  • Longer implementation timeline

Pros and Cons of Using an Aggregator

1

Advantages

  • One integration for a large, pre-certified catalog
  • Faster time to market
  • Simplified contracts and billing
  • Lower technical and compliance overhead
  • Single point of contact for support
2

Limitations

  • Less flexibility and RTP control
  • Custom feature requests may take longer
  • Shared operational risk
  • Ongoing revenue share (aggregator margin on top of studio share)

When to Choose an RGS

Consider a direct RGS integration if you:

  • Want to work directly with studios of your choice
  • You are looking for RTP or any other customization
  • Operate multiple brands that come with distinct technical requirements
  • Want access to raw data
  • Are building a custom platform for long-term growth and better controlled

When to Choose an Aggregator

Consider an aggregator if you:

  • Want a large catalog without multiple certifications
  • Are launching a new casino and need speed
  • Prefer one over many relationship and contracts
  • Have a small technical or compliance team

Can You Use Both an RGS and an Aggregator Together?

Yes. This is the most common setup among established operators. A typical hybrid approach:

  • Connect to an aggregator for quick access to thousands of games.
  • Integrate directly for exclusive titles, RTP customizations, and better control.

This setup allows operators to launch fast while keeping the door open for better control and quality relationships.

How to Decide: RGS vs Aggregator

1

Choose an RGS if you want:

  • Direct studio relationships
  • A platform built for long-term flexibility
  • Maximum control over integration, data, and RTP
  • Isolated operational risk
2

Choose an Aggregator if you want:

  • Quick access to a large game catalogue.
  • Fewer certification requirements
  • Lower initial technical and compliance burden

There’s no one answer, the decision solely depends on your budget, target markets, and growth timeline.

Key Takeaways: Making the Right Integration Choice

The RGS vs aggregator decision isnt about finding the ideal model, but it’s about matching the integration approach with your growth plans and your ability to handle technical and operational complexity.

A direct RGS integration offers better control and closer relationships with the gaming studios of your choice. But timeline and cost increases when it comes to certifications.

A game aggregator offers you better time-to-market and pre-certified game catalog via single API integration.

Before finalizing your ideal fit, it becomes critical to evaluate your budget, target markets, launch timelines, growth opportunities and to ensure you do not have to migrate in the future.
