Random Number Generator (RNG)

A complex algorithm that generates sequences of numbers (or symbols) that are statistically random and unpredictable, ensuring the fairness of game outcomes.

A Random Number Generator (RNG) is the heart of every non-live online casino game. It is a computer program that produces a vast and constant stream of random numbers. When a player hits "spin," the RNG's current number is translated into a specific outcome on the reels.

Crucially for UK players, the RNG software of all games offered by a UKGC-licensed operator must be rigorously tested and certified by independent, third-party auditing bodies like eCOGRA or GLI. This certification guarantees that game outcomes are genuinely random and have not been tampered with by the operator or software provider.

Real-World Examples

RNG Certification Ensures:
- Statistical randomness of outcomes.
- Payouts align with the game's theoretical RTP.
- The game is fair and unpredictable.

FAQs

Can a casino "rig" an RNG?<br>No. At a UKGC-licensed casino, this is practically impossible. The RNG is part of the game software created by the developer and is certified by independent auditors before it even reaches the casino.
