Random number generators have an important role to play in the running of online casinos and the individual games they offer. Without this type of technology, it would be almost impossible for providers to recreate an authentic casino feeling for online players. Performing the same task as a dealer in a real-world casino, they randomize cards and other outcomes. Whereas the dealer would do this with a shuffle of the deck, an algorithm is used to drive the RNG. These algorithms are mathematics formulas, designed to fairly replicate every dice roll, wheel spin or card turn. As their output cannot be accurately predicted, an RNG keeps online play fair, exciting and fun for players.

How does an RNG work?

Whether you encounter an RNG at an online casino or whilst playing a video game, they work in the same way. The starting point is what is known as a seed value, from this number the other random numbers are created. An RNG can produce several trillion numbers each second, but you’ll only see one after hitting the spin button on a slot or deal button on a card game. At this point, the software displays the most recent number or numbers that have been produced. Although casinos cannot manipulate RNG results, they can fix return to player rates to ensure this value is consistent.

Why are RNGs used by online casinos?

Since the first online casino licenses were granted in the mid-1990s, they have searched for new ways of enhancing the experience for their players. RNGs were introduced to manage virtual games that had no dealer and to keep the outcomes free from any external influence. For example, variables such as the size of a wager, the possible pay-off and a client’s status, as a VIP or standard member, will not affect the result. RNGs were soon incorporated into the design of newer titles and allowed developers to deliver more complex gameplay and visuals. The best NJ online casinos have a large collection of quality games, with varying numbers of pay lines and rich graphics. These come with an assortment of promotions and extras, meaning the casino needs complex RNG software to deliver the best possible experience.

Can playing strategies still work with an RNG?

The answer depends on the game being played. Many roulette strategies, in particular, those that rely on mathematical theories will work. This is because RNGs produces random results that align with the principles of these systems. However, card counting strategies are of no use when the game is run through an RNG. This is because each hand is random, so it will be impossible to predict which cards remain in the virtual pack.

RNGs are here to stay

RNGs reassure clients that an online casino is fair and allows the production of innovative new games. For cards, puzzlers and slots which rely on random outcomes, they are a crucial part of the play. By keeping games fresh and unpredictable, RNGs mirror the experience of being in a land-based casino and livens up the action for online players.
