How RNG Certification Works — Are Online Casinos Rigged?

The fear that online casinos rig their games is common, but RNG certification exists specifically to prevent this. Here's how it works.

What is RNG?

RNG = Random Number Generator. It's the algorithm that determines every card dealt, spin result, and dice roll in an online casino. Legitimate casinos use tested, certified RNGs that produce truly random outcomes.

Who Certifies RNG?

The main independent testing agencies: eCOGRA, iTech Labs, GLI, and TST. They audit the RNG code, run millions of simulated spins, and verify the stated RTP matches actual returns.

How to Check

Look for the certification badge in the casino footer. Click it — it should link to a valid certificate with the casino domain listed. If the badge is just an image with no link, that's suspicious.

Live Dealer Games Are Different

Live dealer games use real cards and real wheels, so RNG doesn't apply. The trust factor shifts to the studio's licensing and the operator's reputation.

I always verify RNG certification before recommending any casino. Full reviews at coolshades.net.
