In most online casinos, roulette games are created by third-party software companies rather than the casino itself. Only a small number of operators develop their own games internally. In practice, the casino mainly acts as the platform where the games are hosted, while the provider manages the software, calculations, and technical systems behind the game. This applies to both RNG roulette and live dealer roulette.
- Game Development
For RNG roulette, providers build digital roulette systems powered by random number generators designed to reproduce the behaviour of a real roulette wheel. In live roulette, the provider handles the studio, dealers, cameras, and gaming equipment.
- How Results Are Produced
In RNG games, all outcomes are generated by the software algorithm. In live roulette, providers use wheel sensors and OCR technology to detect the winning number automatically and send the result to the player interface.
- Bets and Payouts
All bets are processed through the provider’s servers. The software calculates wins and payouts instantly in real time once the round finishes.
- Casino Integration
Casinos connect roulette games to their platforms using API systems. This allows operators to display the games and manage player access without controlling the actual gameplay.
- Security and Compliance
The provider remains responsible for system stability, software updates, licensing requirements, audits, and fair gaming standards.
Because of this setup, online casinos cannot directly influence roulette outcomes. The full gaming process operates through the provider’s systems, including servers and live studios. For example, a player in the UK and another player in Germany may both join the same live roulette table while using completely different casino websites. The only difference is the interface and localisation offered by each operator.
Before roulette games can appear in online casinos, providers must complete several certification procedures to prove that their games are fair and secure. One of the first requirements is obtaining valid licences. Not only casinos but also software providers themselves must hold licences.
These licences may come from local authorities such as the UK Gambling Commission or international regulators like MGA and Curacao. Providers must also complete independent testing of RNG systems and RTP accuracy before approval is granted.
To perform these tests, companies work with external laboratories including eCOGRA, GLI, and iTech Labs. These organisations follow ISO/IEC 17025 testing standards as well as GLI-19 requirements created specifically for casino and live dealer games.
Providers are also expected to implement encryption systems and other security measures designed to protect player data. Even after licensing approval, providers continue to undergo regular audits and technical inspections. This process helps maintain fairness, transparency, and reliability across online roulette platforms.
