The Heart of a Fair Casino: The RNG
One of the biggest concerns for casino players at online casinos is whether the games are fair. At the core of a trustworthy online casino is the RNG, a system that ensures game results are completely random. This algorithm creates number sequences that lack any predictable pattern, making them truly random.

How RNGs Work in Casino Games
This technology is always active, powering the games you play. Here’s how it applies to different games:

In Slot Games: When you hit the 'spin' button, the RNG provides a number that corresponds to a specific combination of symbols on the reels. For casino Digital Card Games: For every new hand, the RNG shuffles the digital deck to create a completely random and unpredictable card order. For Online Roulette: The RNG selects a number that corresponds to one of the pockets on the roulette wheel, determining where the virtual ball will land.

The game's result is decided at the point of interaction, not during the visual animation. The spinning reels or the animation of the roulette wheel are purely for entertainment and visual effect.

Auditing and Certification for Fairness
How can players be sure that a casino's RNG is truly random and casino hasn't been tampered with? This is where third-party auditing agencies come in. Organizations like eCOGRA, iTech Labs, and Gaming Laboratories International (GLI) regularly test and certify the RNGs of licensed online casinos. These auditors analyze millions of game results to ensure they are statistically random and fair. Look for these certification seals at the bottom of a casino's homepage as a sign of credibility.
