Casino Software: How Online Platforms Are Built
An online casino is not one system but a stack: a platform layer handling accounts and payments, an aggregator distributing games, and independent studios producing the titles. Knowing which layer does what explains a great deal about how sites behave.

The platform layer owns your account, balance, bonuses and payment processing. The aggregator connects that platform to hundreds of game studios through a single integration. The studios build and certify the games themselves.
This is why two operators can offer identical catalogues but differ completely in withdrawal speed and bonus terms: those belong to the platform layer. Dicebet reviews assess the platform layer separately from the game selection.
RNG Certification in Practice
A random number generator is certified by an independent laboratory that runs statistical tests on millions of outcomes and inspects the implementation for predictability.
Certification is issued to the studio's build, not to the operator. This means the same certified game is genuinely identical across every licensed site, with the exception of the configurable RTP version described in our casino gaming guide.
| Lab | Scope | Recertification | Coverage |
|---|---|---|---|
| eCOGRA | RNG and RTP verification | Periodic | Widely used in Europe |
| iTech Labs | RNG certification | Periodic | Global |
| GLI | RNG and platform testing | Periodic | Global, strong in regulated markets |
| BMM Testlabs | RNG and compliance | Periodic | Global |
| Quinel | RNG and game maths | Periodic | Malta-focused |
Live Dealer Infrastructure
Live games replace the RNG with physical randomness: a real wheel, real cards and a real dealer, filmed in a studio and streamed with sub-second latency.
Optical character recognition reads the physical outcome and transmits it to the platform, which settles bets. The dealer cannot influence settlement, and the studio is monitored continuously.
Why Catalogues Look Alike
Most operators use one of a handful of aggregators, which is why the same few hundred titles appear across dozens of sites. Genuine catalogue differentiation requires direct studio integrations, which are expensive.
The practical implication is that game selection is a weak differentiator. Platform behaviour, payout speed and bonus terms are where real differences sit.
- Identify the licence holder in the footer; that is the platform operator.
- Check whether the operator runs multiple brands on the same platform, which usually share terms.
- Look for exclusive titles, which indicate direct studio relationships rather than aggregator-only access.
- Compare withdrawal terms across brands on the same platform; they are often identical.
- Confirm the live studio provider named in the live lobby.
- Treat catalogue size as a weak signal and payout policy as a strong one.
What Operators Can and Cannot Change
Operators cannot alter game outcomes, paytables or the certified RNG. Those are locked in the studio build and verified by the testing lab.
Operators can choose the RTP version where a studio offers several, set bonus terms, define withdrawal policy and configure limits. That is the entire space in which platforms differ.
Operators configure RTP versions, bonus rules and payout policy. They cannot alter game outcomes, which are fixed in certified studio builds.
