Random Number Generators (RNG) determine the results when you are playing an online slot, a virtual table game, or video poker. How do they work and how do you know that they deliver fair results?

What Is an RNG?

A Random Number Generator is a piece of software that continually generates a string of numbers. The numbers it generates determine the result of a casino game. The software runs in the background when you play slots and table games at an online casino.

RNG software is also used in video games, statistical sampling, cryptography, and computer simulation. It generates many random numbers within a defined scope. The software is powered by very long seed numbers that cannot be cracked or guessed.

For example, an RNG powering a casino game could produce an outcome between 1 and several trillion, hundreds of times every second. This takes place on a constant basis, regardless of whether anyone is actually playing the game. When you hit the deal button or the spin button, it tells the software to display the latest generated string of numbers, which in turn determines the result of the spin.

The RNGs mirror the real-life odds of table games such as blackjack or baccarat, ensuring you get the same results when playing those games online that you would expect at a brick-and-mortar casino. They also follow the RTP (return to player) rate of online slots.

How Do I Know Casino Games Aren’t Rigged?

All licensed online casinos in Connecticut, Delaware, Michigan, New Jersey, Pennsylvania, and West Virginia use RNGs tested by independent authorities to ensure that all their games are fair.

The games can be audited at any time. The audits perform RNG inspections, game and mathematics evaluations, and game payout verifications.

Some states have their own testing teams, such as the Technical Services Bureau (TSB) in New Jersey. The TSB has four distinct divisions – Engineering Unit, Cyber Security and Analytics Unit, Information Technology Investigations Unit, and Quality Assurance Unit – which work together to ensure all online casino games are fair and compliant with regulations.

Other states may work with organizations such as eCOGRA (eCommerce Online Gaming Regulation and Assurance) and TST (Technical Systems Testing), which specialize in examining RNG software.

Legal, licensed online companies must agree to be independently audited without warning. This ensures the games are not rigged and deliver fair, truly random results.

Alternatives to RNG Casino Games

You can rest assured that the RNG-powered games at licensed online casinos are fair and trustworthy. Operators would quickly lose their licenses if they were cheating the system.

However, some players still find RNG software to be impersonal. In that case, you can head over to the live dealer section of an online casino.

You will then be able to connect with real-life dealers in studios via video link. This brings all the fun and excitement of the casino floor into your home or onto your mobile device, without the need to venture out to a retail casino.

You can play roulette, blackjack, table poker, baccarat, craps, and game shows such as Dream Catcher, Monopoly, and Deal or No Deal. You will be able to see the dealer hand out the cards or spin the wheel, so no RNG software is required, and you can chat with the dealer throughout.

Live dealer casinos are regularly audited by licensing bodies, just like brick-and-mortar casinos, to ensure they are treating customers fairly and complying with regulations.
