Have you ever wondered how a deck of 52 cards is shuffled and dealt to every player in an online poker game or how the casino determines which symbols are shown after spinning the reels of a casino slot machine? Typically, these activities are very random, and nobody knows what to expect.
The random number generator (RNG) software online gaming sites use to determine gaming outcomes ensures the randomness at modern pokie sites. The system ensures the house cannot rig or tamper with games and that players cannot influence or predict outcomes. Here is a look at how RNG works in casino gaming.
What is a Random Number Generator (RNG)?
A random number generator (RNG) is a software program that land-based and online gaming sites use to achieve fairness in gaming outcomes. When we speak of provably fair games in the iGaming industry, operators can only offer them because they have a RNG system in place.
The software runs behind the scenes when games are in progress to generate random gaming outputs, ensuring complete transparency and fairness across popular games such as slots, poker, blackjack, and roulette.
In other words, when playing these games, the RNG uses its algorithm in different capacities, including shuffling cards, mixing symbols, and deciding where a ball lands on the wheel. These ensure the casino doesn’t rig its games and players cannot predict results.
Understanding RNG in Online Casinos
Almost all the games at online casinos have an RNG algorithm integrated into their software. The gaming providers use randomness to enhance transparency and fairness. They also do this to comply with gaming regulations that mandate that casinos provide players with provably fair games.
How does RNG work in online casinos? First, it’s important to note that there are two major RNG systems: the True Random Number Generator (TRNG) and the Pseudo Random Number Generator (PRNG).
The TRNG (or Hardware Random Number Generator) creates random numbers from physical devices and elements. These include radioactive actions, thermal noise, and air temperature. The system’s hardware device collects, measures, and interprets the actual values and uses them to generate “true” random numbers.
In contrast, the PRNG uses trained algorithms or software to produce a sequence of random numbers. Instead of real-world factors, it creates an element of randomness using a random seed number, which is why it is called a “pseudo RNG.” However, PRNGs are primarily used in online casino gaming because they are more affordable.
RNGs in Casino Games
Now that the principles of random number generation are clear, let’s look at how the concept works with online casino games.
- Slot Machines
When playing online or at a land-based casino, slot machines depend heavily on RNGs to operate. When a player presses the “Spin” button, the system instantly provides different symbol combinations, which means there are rarely the same outcomes from one spin to another.
- Table and Card Games
The RNG system is also prominent in table and card games such as poker, blackjack, and roulette. These games typically need real human dealers, but the casino ensures fairness using the RNG algorithm for online play.
For example, in a poker or blackjack game, card shuffling and dealing are randomised using an RNG. Similarly, the RNG determines where the ball rests when a roulette wheel is spun.
- Live Dealer Games
In live poker rooms or other live casino games, a human dealer dictates and monitors every activity. When online, the RNG comes into play by determining the order of the card decks, distributing cards, and ensuring security and fairness in every activity.
Challenges With RNGs in Gaming
As the future of gaming shapes up, RNGs are seen as one of the most crucial change agents because of their focus on ensuring integrity and fairness. The main purpose of RNG is to introduce fairness, but the unpredictable results make the results purely based on chance. Instead of getting paid for their skills, players are dependent on luck and frequency of their attempts.
RNGs Enhance the Gaming Experience
The presence of random number generators at online casinos ensures safe and fair gaming across operators and players. Casinos cannot rig their games if they have an effective RNG system in place. Similarly, players cannot manipulate results or predict gaming outcomes because the RNG doesn’t repeat number sequences.
Overall, RNGs create a safe gaming environment for everyone, making it crucial that modern gamers play at reputable online casinos that undergo periodic RNG testing and audits and have verifiable licenses from independent licensing sites such as eCOGRA.
