In online casinos, roulette games are usually developed by third-party software providers rather than by the casino itself. Only a small number of operators create their own roulette products. In most cases, the casino works as a platform that hosts the game, while the provider manages the technical side, including servers, calculations, and game systems. This applies to both RNG roulette and live roulette.
- Game Development
For RNG roulette, providers build software using certified random number generators that simulate the behaviour of a real roulette wheel. In live roulette, the provider manages the studio, dealers, cameras, and broadcasting systems.
- Result Generation
In RNG games, results are produced by the algorithm. In live roulette, wheel sensors and OCR technology automatically detect the winning number and send the information to the game interface.
- Bet and Payout Processing
All bets are handled through the provider’s servers. Once a round ends, winnings and payouts are calculated in real time.
- Casino Integration
Casinos connect roulette games to their platforms through API systems. This allows operators to display games and manage player access without controlling the gameplay itself.
- Security and Compliance
The provider remains responsible for platform stability, software updates, licensing requirements, audits, and fair gaming standards.
Because of this setup, online casinos cannot directly influence roulette outcomes. The full game process runs through the provider’s infrastructure, including live studios and servers. For example, a player in South Africa and another player in Germany may join the same live roulette table through different casino brands while still playing on the same provider’s system. The main difference is the interface used by each casino platform.
Before roulette games are offered in online casinos, providers must complete several certification and testing procedures to confirm fairness and security. One of the first requirements is obtaining gambling licences. Software providers, not only casinos, must hold valid licences. These can come from local regulators such as the UK Gambling Commission or international authorities like MGA and Curacao.
Providers must also test their RNG systems and RTP values through independent laboratories such as eCOGRA, GLI, and iTech Labs. These organisations follow ISO/IEC 17025 testing standards together with GLI-19 rules for casino and live dealer games.
In addition, providers must use encryption systems and other security measures to protect player information. Even after licensing approval, companies continue to undergo regular audits and technical checks. This process helps ensure transparency and fair gameplay across online roulette platforms.
