Understanding How Slots Work: The Role of RNGs

Understanding how slots work helps to bust many myths. The outcome of every online slot game is determined by a random number generator (RNG), which uses mathematical algorithms.

This technology is built into the game, generating thousands of numbers per second. These numbers correspond to symbols on the slot grid. When you bet, play, and spin the reels, the RNG decides the symbols that appear before you.

This means that every reel spin delivers a random outcome. You might see five winning combinations in a row, or you could go 10+ spins without seeing matching symbols land on any of the paylines. It’s how slot randomness works; there’s no way to know what’s coming next.

Independent Auditing & Testing

We only stock games from reputable slot providers, who provide excellent slots. We have top studios like:

• Play’n GO
• Pragmatic Play
• NetEnt
• Red Tiger
• Blueprint Gaming

These studios have the random number generators within their games independently audited, tested, and scrutinised by outside agencies to ensure that the outcomes are truly random and fair.

In the UK, eCOGRA is the most trusted slot RNG auditor. It is responsible for rigorously testing slots from the biggest providers in the business, and the UK Gambling Commission approves its testing methodology.

The audit sees eCOGRA utilise a statistically sound approach to check that the RNGs are genuinely random and haven’t been adapted or altered in any way. Then, in-house mathematicians evaluate the results before certifying the games as random.

Sure, there are outliers, and some offshore studios operate in the shadows, but you won’t find their games at Fruity King. If you’re playing online slots elsewhere from a studio you’re unfamiliar with, always check if its games are audited before placing a real-money wager.

Licensing & Regulation

In addition to the independent auditing process, legitimate game studios, like reputable online casinos, are licensed by gambling regulators. Studios must operate under a remote or non-remote UK Gambling Commission licence to provide their games to British players.

As such, they’re subject to the same high standards of scrutiny as online casinos and must stick to strict terms and conditions to maintain their licence. Part of this is to provide fair games with transparent outcomes that haven’t been tampered with.

So, if you play online slots from a UKGC-licensed studio audited by a company like eCOGRA, you can be certain that the games are not rigged. You might not win each time you spin, but the games offer you a fair chance of winning.

RTPs and House Edge in Slots Explained

While every audited and licensed online slot game in the UK is not rigged, you should know how theoretical return to player (RTP) percentages can influence payouts.

Every studio publishes the RTP of its slot games, which you can check before playing. The average slot RTP in the United Kingdom is 96%, but you will find games ranging from the high eighties to 99%.

The higher the RTP of a slot, the lower its house edge. For example, if a game has a 96% RTP, its house edge is 4%. In real money terms, you can expect this game to return approximately £96 of every £100 wagered over time. That said, RTP is an indicator, not a given.

You cannot use it to predict your exact winnings from a bankroll of £100, as the RTP is calculated over millions of spins. Remember, the RNG means that you could win £100 on a single spin or go 100 spins and only win £5 or £10.

Instead, regard RTP as a measure of a game’s value. It’s better to play games with higher RTPs, as they have a lower house edge and will, over time, offer higher payouts than games with lower RTPs. But it’s also true that you could land a massive win on a low RTP game after just a handful of spins, such is the randomness of online slot gameplay.
