RNG (Random Number Generator)

The pseudo-random number generator (PRNG) that determines every symbol landing on every reel. Under regulation, RNGs must be independently audited by labs like eCOGRA, iTech Labs, or GLI, and re-certified periodically.

A properly audited RNG guarantees:

• Uniformity (each outcome has its correct probability)
• Independence (each spin is independent of history)
• Unpredictability (no external state can be used to forecast the next result)

Casinos operating without RNG certification (some very low-tier offshore operators) cannot be verified for fairness. All major providers and licensed operators publish certification data.

RNG certification is separate from RTP — RTP is a mathematical property; certification confirms the RNG implements it correctly.
