What is RNG? How Online Casino Fair Play Works

April 2026 · 4 min read

Ever wondered if online slots are truly random? Or if the casino can rig the results? Here's how it actually works behind the scenes.

RNG = Random Number Generator

Every licensed online casino game uses an RNG — a computer algorithm that generates completely random outcomes. Thousands of numbers are generated every second. When you hit "Spin", the current number determines your result.

Is it truly random?
Yes. Modern RNGs use cryptographic algorithms that are mathematically unpredictable. Even the casino operator doesn't know what the next result will be.
Can the casino change results?
Not with licensed games. Providers like Pragmatic Play, Evolution Gaming, and PG Soft embed the RNG in their software. The casino platform (like CM8Play) just hosts the games — they can't modify the outcomes.
Who verifies it?
Independent testing labs like eCOGRA, iTech Labs, GLI, and BMM Testlabs. They audit the RNG regularly to ensure fairness. Results are certified.
What about live casino games?
Live games use real physical equipment (cards, wheels) dealt by real humans. Fairness is ensured through multiple camera angles, pit bosses, and third-party monitoring.

What is RTP?

RTP (Return to Player) is the long-term statistical average of how much money goes back to players. A 96% RTP means that over millions of spins, RM96 of every RM100 wagered is returned as winnings.

This does NOT mean you'll get 96% of your money back in one session. RTP is calculated over millions of spins. Short-term results can vary wildly.
