RNG’s, or Random Number Generator, is an RNG software that generates, you guessed it, random numbers.

The Random Number Generator explained

It’s the law of randomness that makes slot machines, betting and gambling so popular and diverting. Players and critics are asking the inevitable question, “Are these casino RNG software really random? There is quite a bit of chatter in the online gambling world regarding RNG’s.

The reality is that casino RNG’s are vital to the online casino industry as without it there is no guaranteed randomness in the game and players would soon lose interest. Designed to be just like a roll of the dice, RNG’s allow players the chance to hit a payout no matter the slot.

So let’s learn some basics about this controversial topic such as how it works? The casino RNG generates random numbers which is triggered by a click or spin, and the outcome is then ran through a game software to create a result as if a dealer had dealt or a slot had been played.

Where is it used?

An RNG software is used throughout the online casino games industry from the obvious slot machines to video poker, roulette and card games. Online games have become accustomed to using casino RNG algorithms to evoke the spirit of randomness. When there is a game that requires a virtual dealer, one of the casino RNG algorithms is put into play instead. All regulated and licensed gambling sites and online casinos use RNG’s, even having them tested by a third party to ensure randomness.

These RNG software evaluations are conducted by an independent third-party that will audit the security and randomness of the software. Once the software is certified as “fair” meaning outcomes are in fact random, the game or slot is accredited.

To check if the casino you are visiting has been certified, you’ll need to visit the software provider’s website to see if they have been granted the proper licenses and certifications. To ensure the safety of your money and bets while playing online, be sure to only play on sites that display their certificate of compliance.

To ensure players as well as casinos are protected, countries like Italy most notably have created in-country regulatory boards. These boards place strict requirements, audits and monitoring in place. In Italy the AAMS (Amministrazione Autonoma dei Monopoli di Stato) certifies the legality of casinos, promotes responsible gambling, analyzes and conducts audits of casino’s as well as releases the coveted certifications for legal operation. In Italy, an AAMS casino certification is mandatory.

Benefits of the casino RNG algorithms

The benefit of online casinos using casino RNG algorithms is assurance to its players that the element of randomness is certified. These automated dealers offer such randomness that it mimics the act of shuffling cards or a coin toss.

As players, the benefit of casino RNG’s will always be in our favor since the outcome will always be random and therefore fair in wins and loses.

The investment casinos and online gaming companies put into RNG software is substantial. The added firewalls, encryption and added security levels makes the challenge of accessing the needed “key” and “seed” nearly impossible.

All these added layers of security ensures the game cannot be altered or somehow influenced by the player predicting the card or symbol.
