Random Number Generators (RNG) Explained

Online slots rely on a system called a Random Number Generator (RNG) to produce fair and unpredictable outcomes.

Each spin is independent, with no connection to previous results, and there’s no pattern players can follow or exploit. Licensed casinos like Jackpot.bet use RNGs to guarantee the integrity of every game.

Knowing how this system works can clear up common myths and help you play with more confidence

How Do Random Number Generators Work?

In online casino games, every spin, card draw, or dice roll is determined by a Random Number Generator (RNG). The role of this system is to produce results that are unpredictable and free from external influence.

There are two types of RNGs relevant to gambling. Understanding the difference between them helps explain how outcomes are generated in online games.

True RNG vs Pseudo RNG

Not all random number generators work the same way. In fact, there are two main types: True RNG and Pseudo RNG, and knowing the difference can help you understand how games work behind the scenes.

True Random Number Generators (TRNGs) rely on unpredictable physical sources - like electronic noise or natural signals - to produce results. You’ll mostly find them in offline environments, such as lottery machines or land-based casino systems.

They’re great for generating real randomness, but they aren’t ideal for the fast-paced needs of online gaming.

Pseudo Random Number Generators (PRNGs) work differently. Instead of physical inputs, they use algorithms to create randomness from scratch.

The process begins with a starting value, called a seed, and then mixes in data like timestamps or device activity to generate results. Even though there’s a method behind it, the outcomes still appear completely random to players.

Most online casinos, including Jackpot.bet, use PRNG systems because they’re faster, more efficient, and perfect for digital games that need to deliver instant results at scale.

Some game providers take it a step further by using CSPRNGs (Cryptographically Secure PRNGs).

To keep things fair and transparent, every PRNG-based game on Jackpot.bet is tested by independent labs.

RNG in iGaming

Below are examples of how RNG works differently in various game types:

RNG in Slot Machines

Slot machines are fully powered by RNG. Every time you press “Spin,” the system instantly generates a set of numbers - each one corresponding to a position on the reels.

Here’s what the random draw decides:

• Which symbols land

• Whether a bonus is triggered

• The final payout (based on paylines and multipliers)

RNG in Table Games

In virtual table games like, RNG handles the role of the dealer or wheel. For example:

• Roulette: RNG selects a number from 0–36.

• Blackjack: RNG determines the next card from a virtual deck.

• Baccarat: The system chooses cards and applies the standard drawing rules.

The rules of the game stay the same, but the draw of each outcome is randomized. The RNG ensures the result follows the logic of the game while staying unpredictable.

Live dealer games, by contrast, use real cards and physical wheels, so RNG doesn’t apply there.

RNG in Poker

In online video poker or RNG-based poker variants (like 3 Card Poker), the system randomly selects cards from a digital deck. Each deal and draw is handled by the RNG. Importantly, the deck is freshly shuffled for every round.

Then, cards are not drawn in advance, but they’re determined as the hand plays out, and outcomes cannot be influenced by previous hands.

However, in real online poker with live opponents, RNG isn’t used to determine wins or losses. It only shuffles the cards fairly before each round. The gameplay decisions (betting, folding, bluffing) are still entirely player-controlled.

RNG Certification in Online Gambling

Even though PRNGs use math, the randomness is only useful if it's verified. That’s why every licensed provider must submit their RNG to independent testing labs, such as eCOGRA, iTech Labs, and GLI (Gaming Laboratories International).

Many games also follow a provably fair model, meaning the game’s logic and outcomes can be mathematically verified by players to ensure transparency. This approach is especially common in crypto casinos and helps build trust by allowing users to confirm that nothing was altered behind the scenes.

Certification typically includes:

• Statistical randomness tests

• Long-term return-to-player (RTP) verification

• Safeguards against manipulation or tampering

If a game passes these checks, it's considered certified and trustworthy.

Conclusion

Random Number Generators (RNG) give us a clearer picture of how fairness is built into modern online gaming. 

These systems are designed to make sure that every spin, card, or outcome happens without bias or outside influence.

We take this seriously. The games on our platform use certified RNGs that meet industry standards for accuracy and fairness. 

Understanding how RNG works doesn’t change the outcome, but it does make the experience more transparent. 

And in online gaming, that kind of clarity matters.

Frequently Asked Questions

How does RNG work in online games?

RNG uses seed values and algorithms to produce unpredictable numbers. When you press spin, the system instantly selects a number and maps it to a game result.

What ensures the RNG is fair?

At Jackpot.bet, RNG systems are independently tested by agencies like GLI and iTech Labs. These audits confirm that game outcomes are truly random and can't be manipulated.

Is the RNG the same for every game?

Not exactly. While the principle is the same, each game has its own implementation and settings. Some games may use cryptographically secure RNGs for added protection.

Does RNG apply to live dealer games?

No. Live dealer games use real cards, wheels, and physical elements. RNG only applies to non-live digital games like slots and virtual table games.
