In most online casinos, roulette games are developed by external software providers rather than the casino itself. Only a small number of operators create their own roulette products. In practice, the casino mainly acts as the platform where the games are hosted, while the provider handles the technical systems, calculations, and game operations. This applies to both RNG roulette and live dealer roulette.
- Building the Roulette Games
For RNG roulette, providers develop software powered by random number generators that simulate the behaviour of a real roulette wheel. In live casino games, the provider manages the studios, dealers, cameras, equipment, and the overall broadcast environment.
- How Results Are Produced
In RNG roulette, outcomes are generated through software algorithms. In live roulette, providers use sensors and OCR technology to detect the winning number directly from the wheel before sending the result to the player interface.
- Bets and Payout Handling
All player bets are processed through the provider’s systems and servers. Once a round ends, winnings and payouts are calculated automatically in real time.
- Casino Integration
Casinos connect roulette games to their platforms using API integrations. This allows operators to offer the games and receive betting information without directly controlling the gameplay.
- Security and Compliance
Software providers are responsible for system stability, updates, licensing compliance, audits, and fair gaming standards. They also handle ongoing maintenance and security protection.
Because of this setup, online casinos cannot directly influence roulette outcomes. The actual game process takes place entirely on the provider’s infrastructure, including live studios and servers. For example, an Australian player using one casino and a player in Germany using another casino may still be sitting at the exact same live roulette table operated by the same provider. The difference is usually limited to localisation and interface design.
Before roulette games can appear inside online casinos, providers must complete several certification and testing procedures designed to confirm fairness and operational security. One of the main requirements is holding valid gaming licences. Not only casinos require licences, but software providers must also be licensed.
These licences may come from local regulators such as the UK Gambling Commission or international authorities like MGA and Curacao. Providers must also pass independent testing for RNG performance and RTP verification.
To complete these checks, providers work with recognised testing labs including eCOGRA, GLI, and iTech Labs. These organisations follow ISO/IEC 17025 testing standards together with GLI-19 requirements used for casino and live dealer games.
In addition, providers must implement encryption systems and other security measures to protect player data and transactions. Even after receiving licences, companies continue to undergo regular audits and compliance reviews. This process helps maintain transparency and trust across online roulette platforms.
