How do RNGs really work in casino games like roulette or blackjack?

The so-called “random number generator” (RNG) is the hidden soul of almost any online casino. When a player spins the roulette wheel, the RNG – which is really just a complicated computer algorithm – gives him or her a random number, just as if someone had shuffled a deck of cards and turned one over at random. Each shuffle is independent: there’s no reason why the last card should affect the next.

So, are these games fixed? This question looms in every gambler’s mind. Well, the reality is that, if they’re designed correctly and tested by reputable third-party auditors such as eCOGRA or iTech Labs, they’re not. Those firms verify the code and make sure it reflects no unfair advantages and that all results occur with the correct odds. Certified casinos typically wear that fact prominently on their sleeve.

Even so, only bet on trusted platforms. Look for licensing information and independent audit reports (often found in a site’s footer or FAQ section). If you can’t find them, don’t bother playing – it’s a scam. A true RNG doesn’t mean you’ll win, but it ensures that the odds of winning are not rigged against you. And with internet technology, as usual, the proof is in the pudding.

Online casinos have RNGs (random number generators). Imagine a machine that flips a digital coin thousands of times every second. Each result maps to a game outcome. How can you trust them? Third-party organizations like eCOGRA or iTech Labs test the RNGs for statistical randomness in their output, ensuring that they aren't rigged. There's no way to prove a game is fair after a single spin, but regular checks by third parties should assuage your concerns. In short, if a site has been properly certified, it's legitimate. Look for clearly displayed certification badges when playing.

Random number generators pump out long sequences of random numbers at high speed. In a game of blackjack, they determine which cards you receive; in roulette, they tell you where the ball lands. The generators cannot be tampered with, since they are designed to produce unpredictable results – neither casino nor player can manipulate their output. And auditors from independent organizations check that the RNGs are working correctly.

RNGs produce a string of random numbers incredibly quickly – often many thousands each second. In the case of roulette, this random output determines where the ball will land; for blackjack, it’s used to create a new “shuffled” deck. How can one be sure these RNGs aren’t rigged? That’s an important question. Independent testing labs, such as eCOGRA and iTech Labs, examine RNGs for unfairness and patterns, and if so, alert the operators. Any casino suspected of cheating is blacklisted. Many honest casinos post their test reports on their websites. Always make sure you play at licensed and regulated online casinos.

The so-called RNG generates an endless sequence of numbers through complicated mathematical formulas. In roulette, it selects a number that corresponds with one of the wheel’s pockets; in blackjack, it determines the shuffled order of the cards. How can you be sure you’re getting a fair shake? Check to see if the game has been tested by industry experts such as eCOGRA or iTech Labs, which make their findings public. Most online casinos proudly flaunt a certificate issued by one of these groups. The takeaway: if you’re playing on a licensed site, the games have been checked.
