Play Slots Online For Real Money at Online Slots UK

Online Slots UK is the best place to play slots online for real money. We have an impressive collection of the industry’s best slot games. 

Due to regulations set out by the UK Gambling Commission (UKGC), demo/free play of slots is not allowed within the UK. This means that if you play slots online, you are playing with real money. You have to deposit funds into your account and use this to place stakes within slot games. But since you are playing with real money, this also means that you can potentially win real money!

So, when playing one of the many online slots we have, any potential winnings earned can be withdrawn from your account. The only exception is any funds still subject to outstanding wagering requirements. 

Therefore, if you’re looking to play slots online for real money, you can’t go wrong with Online Slots UK!

How To Play Online Slots?

One of the reasons online slots are so popular is that they can be so straightforward to play. In the simplest terms, you place your wager, click Spin to start spinning the reels and wait to see the outcome. Once the reels stop spinning, you will find out whether you have won or not. Although slots can vary, they all follow this same basic premise.

However, where slots vary is what can make them interesting! For example, online slots can have a range of different themes. You can get slots based around fishing, ancient Egypt, ancient Rome, Norse mythology, Greek mythology, fruit, outer space, gold mining, magic, Irish-themed slots and more!

Two common ways in which slots can differ are by the paylines and the features they offer. We shall discuss these in more detail below.

Paylines

Paylines are the patterns that explain how matching symbols must land to form a winning combination. So, if multiple matching symbols land on the reels corresponding to one of these patterns, you will receive a payout. 

However, not all slots use paylines. Some slots use ‘ways to win’ instead. These work in a similar way, except instead of landing in a specific pattern, matching symbols simply have to land on adjacent reels. 

Megaways slots are a perfect example of ways to win slots. In Megaways slots, the number of symbols appearing on each reel can change every spin. For example, on one spin, some reels may have only 2 symbols land on them, and others may have up to 7 land on them, then they can change on the next spin. 

Megaways slots usually offer the highest number of ways to win in online slots. Some can have up to 117,649 ways to win or more!

Features

Slots can offer widely different features; these affect how the slot plays out and what potential extras are available to the player. Developers are constantly looking toward innovation; one way is by introducing new features. 

That being said, there are some features that are common among the majority of slots, ones that aren’t necessarily developer-specific.

These common features are worth discussing, as they are likely to appear in most online slots you play.

Wilds, Scatters & Bonus Symbols

Wild symbols are perhaps the most common feature in online slots; their role is simple and could potentially see you land some big wins. Wild symbols typically substitute for all regular paying symbols in the slot, so they can help to complete winning combinations where there may otherwise be a gap. However, they usually cannot substitute for scatters or other bonus symbols.

Scatter symbols are also fairly common. These symbols are typically responsible for triggering the slot’s primary bonus feature, which is usually the Free Spins feature. Scatters work by landing multiple, typically three or more, on the reels simultaneously to trigger the bonus feature; they normally don’t have to land along a payline, just anywhere in view.

The function of bonus symbols is a bit more slot-dependent. They can typically trigger another bonus feature that isn’t the Free Spins feature, such as reel modifiers, re-spins, or a pick-me feature. You can find information on these in a slot’s paytable.

Re-Spins

Slots with respins are fairly common, and the respin feature can play out in a couple of slightly different ways. The most common way respin features work is when a specific symbol lands, it remains in place whilst the rest of the reels spin again, potentially resulting in a winning combination. Alternatively, some slots with the respin feature will have it so that if a winning combination doesn’t land, the reels will respin once for the chance to land a win. This normally occurs during the base game.

Another way respins can work is through a separate bonus round. If a certain number of bonus symbols land, you may trigger a bonus round where only the bonus symbol or empty spaces can land and a number of respins can be awarded. The triggering bonus symbols remain in position, and any that subsequently land reset the respin counter and also become fixed in place. The round normally ends when you run out of respins or all reel positions are filled; in the latter scenario, a jackpot prize may be paid out.

Again, as this differs from slot to slot, you can check the paytable of slots with the respin feature to see how it will play out on that specific slot.

Free Spins Features

The Free Spins feature is fairly self-explanatory. Landing 3 scatter symbols anywhere on the reels, in the same spin is how most slots will have you trigger the Free Spins round. 

After doing whatever is required to trigger the Free Spins feature, you will receive some extra spins at no extra cost. The bet amount of the triggering spin will be used to calculate all potential payouts during the feature. 

Some slots allow you to retrigger Free Spins rounds by repeating the triggering action during the feature - for example, landing 3 scatters simultaneously on a Free Spin. This will award you additional spins, which may be the same number as the initial trigger or different. 

It’s also worth mentioning that some slots don’t have limits on how many times you can retrigger the Free Spins feature.

Prize Picker Rounds

Prize picker rounds are also known as ‘pick-me’ rounds. These can usually be triggered by landing bonus symbols or appear as part of another feature, such as a Free Spins round. Essentially, the game presents you with multiple options, and you have to choose one to reveal a prize. A common version of this is before playing a Free Spins feature, you may have to play through a prize picker round, and the chosen option will reveal the number of Free Spins you receive, or it could reveal a multiplier that will be active for the duration of the Free Spins round.

Prize picker rounds can also be integrated with other bonus features, such as prize trails, or they can be a complete standalone feature. Developers have found numerous ways to implement them into online slots.

Jackpot Rounds

Jackpots can feature in slots in different ways too. They can be won through the base game, perhaps by landing a certain number of bonus symbols, or they can be part of their own bonus round.

If part of a separate jackpot round, they can play out similarly to the aforementioned respins feature. When bonus symbols land and become fixed in position, they normally have a cash value attached, but sometimes they can refer to an available fixed jackpot prize. 

Online slots with jackpot rounds such as these typically have 4 jackpot prizes labelled Mini, Minor, Major and Grand, or something similar. The bonus symbols that correspond to these jackpots award said prize if they land. Often, the Grand jackpot - the top prize - may only be won by filling the reels with the bonus symbols.

FAQs

How Do Online Slots Work?

Online slots are relatively straightforward; you select your preferred bet amount, click Spin and wait for the reels to stop spinning to see the outcome.

Behind the scenes, the slot is run on a Random Number Generator (RNG) that continuously generates large quantities of number sequences per second. Each sequence corresponds to a random outcome on the reels.

So, the instant you press Spin, the sequence generated at that moment determines the outcome you see.

What Are Megaways Slots?

The Megaways mechanic is the creation of developer Big Time Gaming, popularised by their slot Bonanza!

Online slots that feature the Megaways mechanic have reels that can hold different numbers of symbols for each spin. Typically they hold between 2 and 7 symbols, and each reel differs.

This can result in the number of ways to win being in the hundreds of thousands!

How Do Free Spins Work?

Free Spins features can differ slightly from slot to slot, but for the most part, they work in the same way. The feature is typically triggered by landing a specific number of scatter or bonus symbols anywhere on the reels, at the same time.

Free Spins are played at the same bet amount you had placed on the triggering spin, and any potential payouts are calculated according to this amount.

Sometimes you can retrigger Free Spins rounds by landing further scatter or bonus symbols during the feature. You can always check the paytable and the game’s rules to see how bonus features work.

What Are Wilds And Scatter Symbols On Slots?

Wild symbols are special symbols that usually replace all of the standard paying symbols in a slot to possibly help complete winning combinations. However, they normally can’t substitute for any sort of special bonus symbols or scatter symbols.

Scatter symbols are often responsible for triggering bonus features - usually a Free Spins feature - typically requiring 3 or more to land anywhere on the reels simultaneously.

What Are The Best Online Slot Games?

This is a bit subjective, as what might be the best online slot to one player may be different to another. 

It makes sense that many players consider the best slots to be the ones everyone is playing. In light of this, here are some of the most popular slots at Online Slots UK: 

• Starburst
• Big Bass Bonanza
• Fishin’ Frenzy The Big Catch
• Fluffy Favourites
• 9 Masks of Fire

Some players consider slots with higher Return To Player (RTP) rates to be the best slots. As such, here are some high RTP slots available to play on our site:

• Blood Suckers - RTP: 98%
• Zeus Lightning Power Reels - RTP: 97.73%
• Golden Tour - RTP: 97.71%
• Big Bad Wolf - RTP: 97.34%

No matter how you define the best online slot game, Online Slots UK is sure to have something that can suit you.

What Is RTP?

Return To Player (RTP) is the theoretical amount of the money taken in by a slot game that it can pay back out to players. It is an average calculated by the developers over millions of spins.

For example, a slot with a RTP rate of 96.5% should in theory pay out £96.50 for every £100 it takes in. However, as slots are random, there’s no telling how this will be paid out, nor to which players. As mentioned earlier, it averages out as being £96.50 for every £100, but that doesn’t mean it happens every time.

Are Online Slots Truly Random?

Online slots are as close to truly random as possible. They work by having a Random Number Generator (RNG) producing a vast quantity of number sequences every second. Each sequence corresponds to an outcome displayed on the reels.

So, the number sequence created at the moment you click Spin determines the outcome of that spin. The rate at which sequences are generated, and the complex algorithm used to create the sequences, mean this is incredibly difficult to predict.

Each outcome is also an independent event. The previous spin has no bearing on the outcome of the next. Meaning the slot could potentially payout jackpots back to back, or they may not pay out a jackpot for an extended period of time.

What Is Variance/Volatility On Online Slots?

Variance and volatility are largely used as interchangeable terms for the theoretical behaviour of the online slot. The only difference is that variance is often used in relation to long-term behaviour, whereas volatility tends to reference short-term behaviour.

The theoretical behaviour of a slot refers to the frequency of landing a win and the size of the win. For example, high-volatility slots may land wins less frequently than lower-volatility slots, but the payouts are likely to be higher. The reverse is true for low-volatility slots.

Of course, all of this is just theoretical, as slots are random and may play out differently in practice.
