What Is RNG In iGaming: A Complete Guide

RNG in iGaming is a software that creates random results in online casino games. It produces a new, unpredictable outcome each time a player spins a slot or deals cards. This ensures every result is fair and independent from previous ones.

Every day, millions of online casino games spring to life across the globe, each promising an authentic wagering experience.

At the center of these games lies random number generation (RNG), an important technology that most people don’t know about but every game needs.

Just like real casinos use shuffled cards and rolling dice, iGaming depends on RNG technology.

Popular casino games seem simple on the surface– you click a button and win or lose.

But there’s much more happening behind your screen.

Let’s get to the bottom of this!

Understanding RNG In iGaming

RNG in online Gaming is a computer program that creates completely random numbers used in online casinos to determine what happens when you play.

Every time you click to spin a slot or get dealt cards, the RNG picks numbers that decide your result. Just like a dealer shuffling cards in a real casino.

Think about flipping a coin. Each time you flip it, you have an equal chance of getting heads or tails.

It doesn’t matter if you got heads five times in a row- your next flip still has the same 50-50 chance.

That’s exactly how a random number generator works in online games.

Every spin or card deal is brand new and random, not affected by what happened before.

This ensures that the RNG games are fair and nobody can predict or control what will happen next.

The Two Types of RNG: TRNG & PRNG

Online casinos use two main types of number generators to create random results: True Random Number Generators (TRNG) and Pseudo Number Generator (PRNG).

Let’s have a look at both of them:

True Number Generators (TRNG):

True random number generators get their random numbers by looking at things that happen naturally in the real world.

This could be static noise from the atmosphere, the way certain materials break down naturally, or even how you move your computer mouse.

It’s like rolling a real dice- it’s completely random because it uses actual physical events.

However, this method is too slow and costs too much to use in online games that need quick results.

Pseudo-Random Number Generators (PRNGs)

These work by using math formulas to make numbers that look and act random.

They start with one number (called a seed) and use a complicated method to create a long chain of numbers that appear random.

While these numbers aren’t technically random because they come from a formula, they work just fine for casino RNG games because they are fast and reliable.

Which One Is Better?

Most online casinos prefer PRNGs because they can create results quickly.

Testing companies check these systems carefully to make sure they are random enough to be fair.

Even though they use formulas, these formulas are so complex that nobody can guess what number will come next.

Gaming authorities check these systems often to make sure they are working fairly.

How RNG Works In iGaming?

RNG in iGaming begins with what we call a seed number– the starting point for creating random results.

This seed number comes from simple things: when you click your mouse, what time it is down to tiny fractions of a second, or basic information from your computer or phone.

Once the random number generator has this seed number, it runs it through special math steps to create new random numbers.

Each new number comes from the one before it.

The math is so complex that the numbers won’t repeat billions of times.

The most popular system used in online gaming is called Mersenne Twister.

When these random numbers are ready, the game changes them into things you see.

Let’s say you are playing a slot game– if there are 50 different symbols that can appear, the RNG  picks a number and turns it into one of these 50 symbols.

In card games, these numbers decide which cards you get.

Many online casinos use special RNG machines along with their computer programs.

These machines look at tiny random events happening in nature to create seed numbers.

When you combine these machines with computer programs, you get results that nobody can guess or cheat.

Understanding The Significance Of RNG In Online Casinos

In this section, we’ll explore why Random Number Generators (RNGs) are crucial for online success. Read on to find out.

1) Ensure Fairness

RNG in the iGaming system makes sure every player has the same chance of winning.

Whether you are a first-time player or a regular one, the system treats everyone equally.

It works around the clock, creating random results for every spin, deal, or game action.

There’s no bias towards high rollers or newcomers– the outcome is completely random, giving everyone a fair shot at winning.

2) Compliance With Regulatory Standards

Online casinos must follow strict rules about their RNG systems.

Testing labs check these systems regularly to make sure they meet industry standards.

They run millions of tests to look for any problems.

Gaming authorities require these checks before giving licenses to online casinos.

3) Boosts Player Trust

When players know a game uses certified random number generators, they feel more confident about playing.

Regular testing results are often shared openly, showing players that the games are fair.

This openness helps build trust between casinos and players.

Many casinos display their RNG certifications on their websites, proving their commitment to fair gaming.

4) Prevents Manipulation

Random number generator systems are built to stop any form of cheating.

No one can change the results– not the casino, not the players, not even the game developers.

The system is sealed tight against tampering.

Every result comes from complex math that can’t be hacked or predicted.

This security keeps the RNG games reliable.

5) Improves Game Variety

RNG in iGaming allows online casino game providers to create many different types of games.

They can make different types of online slot games with unique features, card games with special rules, and new game styles that wouldn’t work in regular casinos.

The system handles any kind of game outcome, letting creators try new ideas and make more exciting games.

6) Prevents Predictive Patterns

Each game’s results are fresh and independent.

What happened before doesn’t affect what happens next.

You can’t predict future results by tracking past ones.

The system creates truly random outcomes every time, making it impossible to spot patterns or figure out what might happen next.

7) Player Retention And Satisfaction

Fair games keep players coming back for more.

When players know they have real chances of winning, they enjoy playing more.

RNG in iGaming creates exciting moments of surprise and victory that players love.

This fairness and excitement are important reasons why players stick with online casinos that use proper RNG systems.

RNG vs. RTP: What Sets Them Apart?

Comparison between RNG & RTP

Comparative overview of RNG & RTP

Let’s break down these gaming terms in a way that’s easy to grasp.

First, let’s talk about the RNG algorithm.

RNG creates totally random numbers at super-fast speeds that determine what shows up on your screen.

The really important thing to remember is that each spin is brand new– what happened before doesn’t matter at all.

Whether you’ve won ten times or lost ten times, your next spin has the exact chances of winning or losing.

On the other hand, RTP in casino works differently.

It tells you how much money a game gives back to players- but here’s the catch- it’s over a really long time.

When you see a game with 96% RTP, it means if players put in $100, they’ll get back $96…but after millions and millions of play!

In your own playing time, you might win way more or lose way more than that.

It’s super important to know that RTP doesn’t tell you what will happen in your gaming session today or tomorrow.

But then why do people confuse these terms together…

Well, RNG in iGaming and RTP work together in every game like besties.

While the RNG algorithm makes sure each play is completely random and fair, RTP controls how much money the game pays out overall.

The RNG keeps spinning out random results, but somehow, after millions of spins, the total amount paid out matches that RTP percentage we talked about.

This is why you can never predict when you will win- the RNG makes sure of that.

But the game still manages to stick to its promised payback rate over a very long time.

This is why gaming stays exciting and unpredictable.

Every single play could be a win or loss, and there’s absolutely no way to know which it will be.

The Random number generator ensures nobody cheats or predicts what’s coming next, while the RTP ensures the game isn’t completely wild. It follows a pattern over time.

The Role of RNG in Different Casino Games

In this section, we will look at the role of RNG in iGaming in different casino games.

1) Slot Machines

Every time you hit the spin on a slot machine, RNG jumps into action.

It’s working hard behind the screen, picking which symbols will show up in your game.

Think of it this way– every single spin is brand new.

It doesn’t matter if you’ve just hit a huge win or lost ten times in a row– the RNG starts fresh each time, giving you the same chance to win.

2) Card Games

In online blackjack, poker, and other card games, RNG in iGaming handles the cards.

It jumps in before each hand starts, mixing up the virtual deck.

When you play video poker, RNG first picks your initial five cards.

Then, when you decide which cards to keep, it picks your new cards. Each card you get is completely random- just like it should be.

3) Roulette And Wheel Games

Online roulette uses RNG to figure out where the ball lands.

Unlike real roulette where you watch the ball spin around, online roulette uses RNG to instantly pick a winning number.

Whether it’s a regular roulette game with 37 or an American one with 38, RNG makes sure every spin can land anywhere.

4) Diced-Based Game

In online dice game craps, RNG controls what number the dice show.

Every time you hit that roll button, RNG springs into action.

Just like real dice, each roll is totally fresh– your previous rolls don’t affect what comes next at all.

5) Live Dealer Games

Even in live dealer casino games when real people are dealing cards or spinning wheels, RNG still has jobs to do.

It might pick which seat players get, run special online casino bonuses and promotions rounds, or handle side bets.

In games like lightning roulette, RNG chooses lucky numbers that pay extra money if you win on them.

Common Myths About RNG In Online Casinos

Let’s talk about some wrong ideas people have about RNG in iGaming. It’s really important to know what’s true and what’s not when players are playing online.

#MYTH 1: Online Casino Games Are Fixed

Many people think online casinos cheat to make sure players lose.

They worry because they can’t see the cards being dealt or the wheel spinning like in real casinos.

But here’s the truth: online casinos use RNG systems that get checked all the time by independent companies.

If a casino tried to cheat, they’d get caught and lose their licenses to run online casinos.

It’s just not worth the risk for them.

#MYTH 2: You Can Guess When You’ll Win Based On Past Games

Some players think they can figure out when a slot machine will play out by keeping track of winnings and losses.

This isn’t true at all.

Every single spin is brand new like flipping a coin, each flip is totally different from the last one.

#MYTH 3: Casinos Can Change The RNG When They Want

There’s a belief that casinos can fiddle with the random number generator to make players win less.

This just isn’t possible with licensed online casinos.

The RNG systems they use are locked down tight and get checked regularly.

Even the casino owners can’t mess with them- only the companies that made the software could change anything and they’d get caught if they tried.

#MYTH 4: Big Wins Means You’ll Definitely Lose Next

Many players think that after they win big, the game will stop paying out for a while to make up for it.

This isn’t how RNG in iGaming works at all.

Each new game starts fresh– the game doesn’t remember if you just won or lost.

It’s completely random every single time.

#MYTH 5: Practice Games Are Different From Real Money Games

Some players think casinos make practice games pay more to trick people into playing for real money.

Actually, practicing games and real money games use exactly the same RNG system.

The only difference is that you are not using real money in practice mode; everything else is identical.

Wrapping Up…

RNG in iGaming has changed the game in online casinos- quite literally.

What began as a way to make online games fair has grown into something much bigger.

It’s proof that technology can make gaming both exciting and trustworthy.

As iGaming keeps growing, this simple yet powerful system stays at the top of every digital spin, shuffle, and deal.
