Random Number Generator (RNG)

Random Number Generator (RNG) is a software system installed within a game engine or remote game server that produces unpredictable, statistically random number sequences that determine game outcomes, ensuring independence and fairness across spins, deals, or draws in online casino games.

In iGaming, RNGs are implemented as certified pseudo-random or cryptographic algorithms with controlled seeding and statistical quality checks (for example, uniformity and non-correlation). Independent testing laboratories certify RNG compliance before release and through periodic audits.
