How do RNGs work in online casino games?

RNGs are basically the electronic version of a roulette wheel or a slot machine at a casino. They are computer programs that calculate numbers at high speed (thousands per second), and when you press the ‘spin’ button, whatever number the RNG happens to be calculating at that moment will determine the outcome of your spin. Since each number in an RNG stands for a particular symbol on a reel (or a pocket on a roulette wheel), every spin is completely independent and random. Licensed casinos must use audited RNGs from vendors such as eCOGRA – these are rigorously tested by independent third-party companies to ensure fairness. If you play in a licensed casino, you get exactly the same chance of success as you would in a traditional casino. Play wherever you want. It’s all in the program.

So what’s RNG? A computerized equivalent of a shuffled deck of cards or a rolled die. It is an intricate formula that generates (usually millions) of numbers per second and, in the case of slots, determines which symbols are displayed on the payline. In roulette, it selects the winning number. The important thing to remember is that these outcomes are totally random and unpredictable. Responsible Internet operators work with third-party regulators such as eCOGRA or iTech Labs to test this randomness, so players can always be sure the results are fair.

Random number generators (RNGs) are essentially the equivalent of casino dice. They generate thousands of computer-generated numbers per second – so many that no one could ever hope to guess the next one. Once you click to spin a slot machine or place a wager on the roulette table, the next available number is plucked from that sequence; it’s like stopping a movie at a random point in time. RNGs are designed to prevent patterns from emerging. Legitimate online casinos employ independent software testing to ensure their RNGs aren’t tampered with, so there’s no chance of rigging the game. So yes, when you play at a licensed and regulated online casino, the results are authentic. Pure chance.

When it comes to RNGs, the technology works very much as a deck of cards would. An RNG generates random numbers that decide which symbols line up on a slot machine – or where the roulette ball lands. Honest operators use third-party audited RNGs such as those certified by the International Casino Testing Labs or eCOGRA, which means players can’t be cheated. Like a shuffled deck of cards, you never know what’s going to come out next.

RNG stands for Random Number Generator. When you play an online slot machine or roulette, the RNG generates millions of numbers that are combined to select the winning combination. These numbers are generated and selected instantly, so there is no way to predict results (not even for the house). You can rest assured that the RNG has been certified by independent organizations such as eCOGRA to ensure it is a fair game.
