Randomness is the lifeblood of gambling — it’s what keeps players on the edge of their seats, anticipating what the next spin, roll, or shuffle might bring. But when gaming moves into the digital realm, how do we ensure that randomness remains fair and truly unpredictable? Enter RNG, or Random Number Generators — a cornerstone technology in the world of iGaming.
In this guide, we’ll break down what RNG means, how it works, and why it’s essential to the integrity of online gaming. And for extra spiciness, we’ll sprinkle in some fun facts from the world of modern tech and their efforts to achieve true randomness.
RNG stands for Random Number Generator — a technology that produces sequences of numbers without any predictable pattern. In iGaming, RNG is used to determine the outcomes of games like slots, roulette, or virtual card games. Simply put, it’s what makes sure your online blackjack isn’t secretly a game of “Guess What the Casino Wants.”
When you spin a slot machine or draw a card in an online game, the RNG ensures that the result is entirely random. This randomness is key to fair play — players need to trust that every roll of the virtual dice isn’t rigged in the house’s favour.
RNG-based games and Live Dealer games are like two sides of the same casino coin. Both are fun, but they work in very different ways:
1. RNG-Based Games:
These include slots, video poker, and other games of chance where an algorithm determines the outcome. The experience is quick, automated, and relies entirely on software to deliver results.
2. Live Dealer Games:
These games replicate the atmosphere of a physical casino, complete with real human croupiers. The randomness here comes from physical actions, like shuffling cards or spinning the roulette wheel, rather than software.
Random Number Generators come in two main flavours, both with the same goal: to produce unpredictable outcomes.
These rely on physical processes — like atmospheric noise or temperature changes — to generate randomness. TRNGs produce results that are genuinely random because they’re based on processes that cannot be predicted or replicated.
Example: Measuring the time between mouse clicks or the natural decay of radioactive isotopes (yes, really) can be used to create true randomness.
These are algorithm-based and use a starting value called a “seed” to produce random sequences. While technically deterministic, PRNGs are designed to be practically unpredictable, making them ideal for most iGaming applications.
Fun Fact: If you know the seed and the algorithm, you could predict PRNG outcomes — but good luck with that; it’s like trying to guess the winning lottery numbers with a blindfold on.
Speaking of true randomness, here’s a fun detour: lava lamps. Yes, the groovy decor item from the 70s is now playing a starring role in digital security. Cloudflare, a major web security company, uses a wall of lava lamps in their San Francisco headquarters to generate randomness. Cameras record the unpredictable patterns and motions of the lava lamps, and this data is then converted into random numbers.
Why lava lamps? Unlike PRNGs, which rely on algorithms, the randomness in physical phenomena like the fluid dynamics of lava lamps is truly unpredictable. Factors like heat, flow, and light interaction combine to create chaos that even the best mathematicians couldn’t predict. This makes them perfect for generating randomness in applications where security is paramount, like encryption.
For iGaming, though, PRNGs do the job just fine. While a lava-lamp-powered slot machine might sound fun, the computational power and efficiency of PRNGs ensure that the randomness in your favourite games is up to par, without the need for a groovy light show.
Imagine spinning a slot and knowing the outcome beforehand — it would take all the excitement (and fairness!) out of the game. RNG ensures that:
Certifying RNGs is a critical step in ensuring that online games are truly fair. Reputable testing labs provide certifications that verify the randomness and fairness of these algorithms. Here are some top certifiers:
A veteran in gaming certification, BMM conducts rigorous tests to validate RNGs for various jurisdictions worldwide.
Known for its comprehensive “diehard tests,” iTech Labs ensures that RNG algorithms comply with international standards.
GLI’s certifications are globally recognised, making it a go-to authority for iGaming operators.
A London-based agency that guarantees fair play, eCOGRA’s seal of approval is a hallmark of gaming integrity.
RNG and RTP (Return to Player) often get mentioned together, but they serve different purposes:
While RNG handles the fairness of individual spins or rounds, RTP looks at the broader picture of player payouts over time. Together, they ensure a balanced and trustworthy gaming experience.
Behind every spin, shuffle, and roll in iGaming is a bit of mathematical wizardry. RNGs are the unsung heroes of online gaming, creating experiences that are fair, unpredictable, and endlessly entertaining. Whether it’s generating a jackpot-winning spin or just giving you another shot at those elusive cherries, RNG ensures that every outcome is as random as a coin toss on a windy day.
So next time you’re playing a slot or rolling virtual dice, spare a thought for the humble RNG. It’s the quiet genius keeping the game alive — and the odds honest.
And if that thought doesn’t light up your day, perhaps a lava lamp will.
