RNG Explained: How Casino Slots Give You Fair Results

When you visit a trusted UK online casino, you’ll find a huge range of slots from leading software brands. Whether you want to play a horror slot filled with vampires or something sweeter, you can take your pick of almost any theme and style. 

On top of that, a good selection of slots offers diverse volatility levels, payouts, and bonuses. But all slots, from simple 3x3 games to elaborate jackpot slots, use random number generators (RNGs) to deliver fair results. 

But what are RNGs, and how do they create unpredictable outcomes? In this post, we’ll explain:

• How RNGs function behind the scenes to give you fair results
• Why RNGs are so important to a satisfying and transparent player experience
• Online casino games that don’t need an RNG to provide you with a fair outcome

RNG in Online Casino Slots: How They Keep Gameplay Fair 

From high rollers to casual players who want to minimise risk, the diversity of slots on the market ensures there’s something for everyone. But no matter which slots you play at online casino sites, one of the most important elements they all share is the RNG.

RNGs function behind the scenes to deliver an unpredictable result each time you spin the reels.There are two different types of RNG software:

• Pseudorandom number generators (PRNGs)
• True random number generators (TRNGs)

PRNGs vs TRNGs

A PRNG algorithm generates thousands of number sequences each second, but this process stems from a random seed value. 

Meanwhile, a TRNG uses no seed value. Instead, it produces number sequences in response to certain unpredictable triggers (e.g., a specific sound). TRNGs are a common solution for ensuring randomness in highly secure applications. These include apps that rely on cutting-edge data encryption to protect information. 

Of the two types, PRNGs are the go-to for software brands creating slots for online casino sites. But as they use an initial seed value, PRNGs don’t deliver truly random outcomes in the same way that TRNGs do. 

However, the results generated follow no clear pattern, so they’re still virtually impossible to predict. This prevents any player from working out when certain symbols will appear and in what positions they will hit.

Whether you play on a desktop or mobile, slot PRNGs work in the same way:

• The PRNG software generates thousands of random number sequences each second. 
• Every symbol or reel position in the game corresponds to one of the numbers generated. 
• When you press the ‘spin’ button, the PRNG picks the most recent number. 
• The symbols corresponding to the selected numbers land on the reels. This creates an unpredictable layout that may or may not form winning combinations. 

One of the most important factors of RNGs in slots is that no two spins are connected. Each time you tap the ‘spin’ button, the outcome is entirely unrelated to those that came before and any that follow. 

This is why the concept of a winning or losing streak is unrealistic: there’s no pattern to the results — every spin could lead to a win or loss. 

Online Casino Games That Don’t Need RNGs to Deliver Fair Results

While PRNGs are essential in slots at licensed online casino sites, they’re not necessary in every game. Virtual games based on such casino classics as blackjack and roulette use PRNGs to create fair results. Even the latest crash and Slingo games use them, too. 

But live casino games have no need for RNGs (except for some automated bonus features). These are designed to recreate the experience of playing at a physical casino with a trained dealer. In some cases, live games even stream directly from brick-and-mortar casinos for added authenticity.

However, all live games are fair for the following reasons:

• The dealers use tried-and-true methods when taking essential actions (e.g., dealing cards, spinning roulette wheels). 
• Operators invest in the same industry-standard equipment as physical casino venues. 
• Comprehensive camera coverage ensures that dealers and key components, such as playing cards and roulette balls, are visible at all times. 
• Online casino sites licensed by the Gambling Commission of Great Britain are tightly regulated and expected to follow strict rules. Any indications of dishonest behaviour on an operator’s part can lead to fines and legal action. 

This is why it’s so important to only play at licensed casino sites. If you don’t see the Gambling Commission logo in a casino’s footer, the site may not have a licence to operate legally in the UK. 

Conclusion

All slots at licensed UK casinos use RNG technology to give players a fair and reliable outcome. Each time you spin the reels, you have a chance to grab a prize — no matter whether you won or lost in the previous spin. 

There is no rule preventing the same symbols from landing in the same positions again and again across consecutive spins. On the other hand, one combination may not be repeated for a huge number of subsequent spins either. This is the unpredictable nature of the game.
