Why is RNG Important in iGaming?

Suppose you’re spinning the reels of your favorite online slot or watching a digital roulette ball bounce around the wheel. 

The thrill is in the unknown, will you hit the jackpot or miss out by a hair’s breadth? 

This sense of fairness and randomness isn’t magic, it’s engineered through Random Number Generators (RNGs).

For operators, RNG in iGaming isn’t a feature, it’s a foundation of trust, compliance, and player satisfaction. Here we’ll explain why RNG is so important in iGaming, how it works, and what it means to operators who want to deliver top-notch gaming.

What is RNG in iGaming?

In simple terms, RNG (Random Number Generator) is the technology that generates random and unpredictable outcomes in iGaming. Whether it’s the spin of a slot, the shuffle of a virtual deck, or the roll of dice, RNG ensures every outcome is independent, impartial,l and can’t be manipulated.

For example, in slots, RNG decides which symbols appear on the reels, creating billions of possible outcomes. In poker or blackjack, RNG shuffles and deals the cards, mimicking a real-life game. For roulette or virtual dice games, RNG in iGaming ensures every spin or roll is unique and fair.

Without RNG, fairness and unpredictability, the two things that make gaming exciting, wouldn’t be possible.

Types of RNG in iGaming: The Foundation of Fair Play

Online casinos are built on fairness and randomness and the engine that drives this is the Random Number Generator (RNG). While all RNGs do the same job – deliver random results – not all are created equal.

Pseudo-Random Number Generators (PRNGs)

PRNGs are the bread and butter of online casino gaming. These generators use algorithms and a starting point called a seed value to create randomness.

• Why PRNGs are good for Online Casinos: PRNGs are fast, cheap, and efficient so are perfect for games like slots, blackjack and virtual roulette. They make every spin, shuffle or deal feel random.
• How They Stay Secure: While PRNGs run on advanced algorithms, encryption protects the seed value. Certified PRNGs are tamper proof so players can expect fair gameplay.

True Random Number Generators (TRNGs)

Unlike PRNGs, TRNGs use physical processes – like electrical noise or light refraction – to produce truly random outcomes.

• Niche Applications in Casinos: TRNGs are for high stakes or special games like unique promotions or events marketed as “provably fair”.
• The Trade-Off: TRNGs require a lot of resources so are reserved for specific use cases rather than daily casino operations.

Impact of RNG on iGaming

In the real world of online casinos, RNG doesn’t just deliver randomness; it has a domino effect of benefits for players, operators and the industry.

Fairness and Transparency

RNG gives players trust in the platform. Certified RNGs – tested by bodies like eCOGRA and GLI – have to meet industry standards and pass regulatory audits.

Player Engagement

Ever wondered why players come back for one more spin? It’s the randomness of RNG. Whether it’s hitting a rare jackpot or landing a bonus round, RNG in iGaming keeps the game exciting and addictive.

Operational Integrity

RNG protects the casino’s reputation. It prevents external interference and ensures compliance with global regulations which is key to keeping licenses and player trust.

Why RNG Compliance is Key for Operators

Regulators worldwide demand RNG certification for fairness. For iGaming operators RNG compliance is not just a regulatory requirement, it’s a business imperative.

• Trust: Certified RNGs show players you’re fair. iTech Labs and GLI test RNGs to global standards.
• Penalties: Without RNG compliance you could be hit with big fines and your license can be revoked, which will damage your brand.
• Licensing: In regulated markets worldwide a certified RNG is often a requirement for a gaming license.

RNG Myths in Online Casinos

Myth 1: RNG Can be Predicted or Hacked

Fact: Certified RNGs use encryption and algorithms that can’t be tampered with. Testing agencies check for vulnerabilities regularly.

Myth 2: RNG Favors the House

Fact: RNG is separate from the casino operator. House edge is from the game’s RTP and design, not the RNG.

Myth 3: All RNGs are the Same

Fact: PRNGs and TRNGs are for different purposes. While PRNGs are for efficiency and cost, TRNGs are for high-security applications.

RNG in iGaming: Use Cases

RNGs are behind every part of online casinos. Here’s how they work in the most popular games:

Slots

Every spin is RNG generated from billions of combinations. Whether it’s a small win or a big jackpot, every outcome is unique and independent.

Table Games

In games like blackjack or baccarat, RNG simulates the shuffle of a real deck. So players can’t predict the next card and every round is fair.

Live Dealer Games

Even live dealer games use RNG for bonus features or side bets. It adds randomness without removing the human touch.

Final Thoughts

RNG is the basis of fairness, excitement and trust on iGaming platforms. Certified RNG games keep players engaged, meet regulatory requirements and ensure your platform is secure. When RNG in iGaming is implemented right, it makes your platform globally compliant and helps you build a trusted gaming platform. Let our experts make randomness work for you!
