Practical tips for choosing trustworthy slot sites

Check the UK gaming licence

All our UK slots sites have a gaming licence issued by the UK Gambling Commission. When you play on licensed UK casino sites, you'll know that the casino has to comply with some of the strictest licensing conditions in the world.

Finding the following elements on a slot website should tell you that the casino is properly licensed:

• UK Gambling Commission logo
• A reference to the casino's licence status
• The licence number

The first place to look is the footer on the casino's homepage. If you can't locate the licensing info there, it might be displayed on the 'About us' page instead.

Look into the slot game providers

There are plenty of slot providers out there and the selection varies from one slot site to another. Some lesser-known companies may hold some hidden gems. However, not finding any of the household names on the site should be a red flag.

The most widely available slot makers are Netent, Microgaming, Playtech Play'n GO and Scientific Games. On Bojoko, we have listed:

However, there are many fresh game suppliers producing quality slots on a regular basis.

Read reviews of the UK slots sites

Our slot site listings are created by the slot sites themselves. They in turn are rated by the Bojoko community and our casino testers.

The community ratings consist of a numeric rating with a comment summarising the players' experience.

The reviews by casino testers are more detailed. After thorough testing, including a real money deposit and withdrawal, they carefully cover all aspects of the slot site in question.

By checking out our online casino reviews, you'll know what players just like you think about these slot sites. The ratings made by users help you pick the best online slots sites to play slots and win. You can also have your say and write your own reviews to contribute!

Try slot sites with a bonus

Casino bonuses can be found on practically all casinos and UK slot sites are no exception.

There are plenty of options to choose from. They're targeted at slightly different player types:

• No deposit bonuses and free spins have you spinning in no time without needing to make a deposit
• Low wagering bonuses and no wagering bonuses have simple terms and offer great value
• Deposit match bonuses can give you a nice boost to your gaming budget right from the start

FAQ

Although it's hard to name a single best slot site, here are some great options to start with:

Not all slot sites publish their payout rate. From those that do, here are the 3 best slot sites for winning:

• Hyper Casino - 97.0%
• Tonybet - 97.0%
• VideoSlots - 95.7%

As long as the site is licensed by the UK Gambling Commission, it can be considered trustworthy. On Bojoko, we only show UK-licensed online slot sites.

Being licensed by the Gambling Commission means following very strict licensing conditions. Breaking them often results in fines and/or losing the gambling licence. That's why licensed slot sites have a strong incentive to play fair and keep their licence.

Although there are some sites focused 100% on slots, most also offer a wider range of games. These include:

• Jackpot games
• Bingo
• Poker
• Blackjack
• Roulette
• Scratch cards
• Lottery
• + many more

Check out our Casino games page to learn more about different types of games.

Yes. You can either:

• Test the slots in free mode to learn how they work, or
• Get a no deposit bonus and have a chance to win real money

In the UK, both of these options require you to create an account on a slot site.

Offering no deposit bonuses is one of the main channels for slot sites to acquire new players. A free sign-up bonus gives you a possibility to win money without depositing your own cash.

On the No deposit bonuses page you can see all UK casinos offering no deposit free spins and other free sign up bonuses.

Slot sites usually offer the registration bonus as no deposit free spins. Sometimes you can also get free bonus money without making a deposit.

Free spins are given to a specific online slot, whereas free bonus cash can be used for practically any game. Only the highest RTP slots, table games and live dealer casino games are usually excluded from bonus play.

Read the terms and conditions of the no deposit bonuses to avoid any hidden catches. Make sure wagering requirements, withdrawal caps, maximum bets and restricted games don't come to you as a surprise.

How do slots work?

When it comes to basic mechanisms, most online slots resemble the physical slot machines. As a legacy of the old 'one-armed bandits', there are many familiar elements:

• Reels
• Winning symbols
• Paylines
• Info pane
• Bet selection

When you start a round, the reels begin to spin. You want to line up similar symbols to consecutive reels, starting from the left. If you get enough of the same symbol on a payline, you win. How much? That you can find on the paytable, accessed via the info pane.

Before each round, you have the option to adjust the size of your bet.

Reels

The main game area consists of vertical reels stacked together. The most prevalent layout is 5 reels with 3 symbols showing on each.

However, there are both bigger and smaller layouts. The traditional 3-by-3 reel setup is still popular in classic slots. The biggest go up to 6-by-12 or 9-by-9.

Symbols

The winnings are based on getting symbols on the reels in pre-specified combinations. The highest paying symbols are usually chosen to match the theme of the game. The low-paying symbols are usually:

• Card deck suits: ♣️ ♦️ ♥️ ♠️
• The top value cards of the deck: A, K, Q, J and 10. Sometimes also 9 is included

Paylines

Most games feature specific paylines on which you need to get rows of symbols. In most games, the paylines only go from left to right, meaning your winning combination needs to start from the leftmost reel. The longer the row of symbols you get, the bigger your win.

The number of paylines varies. Few games may even have only one paylines; most feature about 20, and some boast hundreds or even thousands of paylines.

When the number of lines exceeds the 100-mark, you can usually stop looking at the actual paylines. Instead, game suppliers speak of e.g. '243 ways to win'. As long as there are the same symbols on the consecutive reels starting from the left, you're in for some winnings.

In the early days of online gambling, some slots had the option to choose the number of active paylines. However, it's quite rare now.

Info-pane

The info pane button is usually located in the corner of the game screen and marked with one of the following symbols: i, ? or 🏆.

From the info pane, you can view the:

• Payouts for different symbols
• Number of symbols needed for different wins
• Descriptions of the special features
• Payline layout
• Rules of the game

Check out the info pane and you'll better understand what's happening in the game.

Bets

Apart from certain jackpot slots, you can select how much you want to bet per spin. The total bet size is affected by:

• Number of paylines (sometimes shown as 'bet')
• Number of coins per payline (level)
• Coin value

EXAMPLE: There are 9 active paylines with 1 coin per payline and 10p coin value. Your total bet per spin is 9 x 1 x 10p = 90p.

This may sound complicated, and some game suppliers have made choosing the bet size unnecessarily confusing.

Many game providers like to goof around with coin wins. Having a thousand coins clattering to the virtual money tray may sound appealing. However, with coin size at 1p, your joy may be short-lived.

Some suppliers have taken a different approach. Instead of tweaking the coin amounts and sizes, you can just pick the total bet from a list.

Slot special features

Videoslots are the most popular game type of online casinos. In addition to unique themes and dazzling graphics, they come loaded with special features. These include different versions of:

• Wild symbols
• Scatter symbols
• Free spins
• Bonus games
• Re-spins
• Expanding reels
• Big symbols
• Win both ways

Below, you'll find detailed descriptions of all special features. Use our UK slot list to filter games based on your favourite features.

Wild symbols

The wild symbol helps you create more winning combinations. It works in a similar way as the joker in poker. Whereas the joker replaces the missing card in your hand, the wild symbol fills in for the missing symbol on the payline.

The wild symbol replaces any base symbol of the game. If the same wild is on multiple paylines, it can simultaneously stand-in for several winning symbols.

However, the wild symbol doesn't replace special symbols, e.g. scatters.

In addition to standard wilds, some games feature more specialised wilds:

• Sticky wilds stay on the reels for another round
• Walking wilds travel on the reels between rounds
• Stacked wilds appear on the reels as tall columns of wilds
• Random wilds are sprinkled on the reels after the spin
• Multiplier wilds multiply the winnings from the participating combinations

Scatter symbols

Scatter symbols are the slot special symbols that unlock free spins, bonus games or coin wins.

Unlike ordinary symbols, scatter symbols don't need to land on a specific payline. You only need to get a certain number of them on the reels. In many games, you need 3 scatters to launch the free spins or the bonus round.

Free spins

Free spins is a confusing term. It can refer to free game rounds that casinos use to attract new players. On our free spins page, we tell you how to get no deposit free spins. This is one of the most common forms of casino bonuses.

In-game free spins are a completely different cup of tea. You don't get them as a bonus from the casino; you win them by playing the game. You usually need to land 3 scatter or free spins symbols on the reels to start this feature.

You always get a certain amount of free spins. In some games, the exact number of scatters landed may affect the spin amount. In others, you can win more spins during the feature itself.

The spins are given in the same bet size you used on the round where you unlocked the spins.

EXAMPLE: You play with a £1 bet and win 20 spins. Every one of these spins is worth £1, landing you a total of £20 worth of spins. While you're playing the free spins, they don't use up your real money balance.

When the free spins start, the appearance of the game often changes to make them distinct from the main game. The free rounds may also have some extra perks compared to the base game. Here are a few examples:

• There may be a multiplier for all free spin winnings
• Some low paying symbols may be removed from the game during the free spins
• You may get additional wilds

There are also free spins games, where you can decide the exact nature of the feature. For example, you may choose between a larger number of spins with fewer extra perks and a smaller number of spins with more winning potential.

You may need to hit the feature several times to unlock all the options.

Bonus games

Bonus games are special features which often offer much bigger wins than the base game. You usually need to land a certain number of scatters on the reels to start the bonus game. In some slots, you can launch the bonus feature by paying a lump sum. This is known as Buy bonus.

Bonus games differ a lot from each other. Some may require decision making or quick reactions. The simplest and most common version is the pick-n-click type of game. You reveal coin wins, free spins and other rewards by clicking treasure chests.

Re-spins

Re-spins let you spin some or all the reels again without placing an additional bet.

Just like there are many kinds of wilds, there are also various types of re-spins:

• Walking re-spins make the reels spins again and again until the special symbol exits the reels
• Cascading reels explode all the symbols of the winning combination to make way for new wins
• Sticky re-spin re-rolls all the spaces that aren't part of a winning combination. This continues until there are no new wins

Sticky wins

The sticky win isn't exactly a re-spin, but it resembles this feature class a lot. When you win, the winning combinations stay on the reels for an additional round. You need to place a standard bet, though.

Other features

Expanding reels

Expanding reels copy themselves on one or more neighbouring reels or add completely new places for symbols. This helps create longer, more valuable winning combinations.

Colossal symbols

Colossal symbols are bigger than the standard 1-by-1 symbols. They help create big clusters of the same symbol.

NetEnt's Spinata Grande is one of the most popular slots with colossal symbols.

Win both ways

In most slots, the paylines only go from left to right. You'll only get wins, if:

• You have the same symbol
• On the same payline
• On the consecutive reels (no gaps)
• Starting from the left-most reel

When you have a slot with wins both ways, the paylines can go from right to left and left to right. This practically doubles the number of wins.

The most famous slot with wins both ways is NetEnt's mega-hit Starburst.

Try different types of online slot machines for real money

Real money slot machines are the favourite game category for most casino players. There are many different types of online slot machines available at UK casinos.

Below, we'll cover the main aspects of these games. Discover your favourites and play slots online.

Modern video slots

Modern video slots constitute the bulk of the online casino slot games in the UK market.

Bursting with cool themes, features and graphics, these games can be very elaborate. They often feature storytelling, engaging animations and prolonged features to keep players on the edge of their seats.

There are many options to choose from, and it's not always easy to find the perfect game by trial and error. On Bojoko, you'll find:

• Detailed information about about the slot and its features
• Tools to discover and compare similar slots
• Lists of casinos where to play these slots for real money

Fruit machines

Fruit machines are some of the simplest slots available. Modeled on the physical, coin-operated pub slots of times gone by, the online versions give the fruit machine a modern spin.

Online fruit machines can be divided into two categories:

• Classic slots closely replicate the old pub slot machines
• Fruit-themed slots use the familiar fruit symbols but include some modern features too

Progressive jackpot slots

Progressive jackpot slots feature a jackpot that grows until someone wins it. Whenever you make a bet on a progressive jackpot slot game, a portion of the money goes to the slot machine jackpot. The pot grows continually until some lucky player hits the winning combination.

Progressive slots offer the most lucrative potential out of all casino games out there. You can play them at most UK-licensed online casinos.

Penny slots

Penny slot machines are the budget-friendly solution for many slot fans. With a minimum bet of only 1p per payline, you can spin for hours without making a big dent in your bankroll.

Most slots now have fixed paylines. Before you venture out to play penny slots online, you need to make sure to pick a slot that allows you to select the number of active paylines.

Return to our online slot list and apply the Penny slots quick filter to see slots you can play for 1p per spin.

High limit slots

High roller slots are the best option for slot fans with deep pockets. The maximum bet goes up to hundreds or even thousands of pounds per spin. These high limit slots are a natural choice for players who aren't afraid to risk big to win big.

On Bojoko slot reviews, you can see the maximum bet and pick accordingly.

Mobile slots

Mobile slots are the mobile-friendly version of the desktop slot games. Usually, the game is 100% the same, whether you play it on your computer, smartphone or tablet.

Sometimes, the controls may be optimised for a tiny screen, making it easier to use with just one hand. Some slots are also optimised for both screen-orientations (landscape and portrait mode).

In 2021, all new releases are published on mobile. The support for Flash - a technology which used to dominate the desktop slots - was ended in December 2020. That's why practically every game studio has switched to the mobile-friendly HTML5 technology.

On Bojoko, you can find HTML5 slots by using the filter called Support all devices.

Some of the old, obscure games are going to disappear from the game libraries for good. However, many studios are re-launching their older classics in a mobile-friendly format.

Best payout slots

High RTP (Return to player) slots have the smallest house edge of all online slot games. The RTP percentage tells you the share of your bets you can expect to win back.

These are averages calculated over thousands of spins. The results within a single gaming session may vary significantly.

We have listed the best payout online slots in the UK based on their RTP. Go back to the slot list and apply the Highest RTP quick filter. You'll see the top 10 best payout online slots available in the UK.

Compete in slot tournaments online

A slot tournament is a form of casino competition. There are different types of slot tournaments online. In some categories, you have to hit the biggest coin win in one or over several spins; in others, you need to wager the most in a certain slot.

You can find all the casino competitions and slot tournaments on our Casino offers page.

How are slots licensed in the UK?

Getting a slot from the developer's desk to the player's hands isn't as easy as you might think. There are a lot of regulatory bodies who need to make sure that every single part of the game is fair and square. This is no place for cheaters.

In the case of Great Britain, the regulator who watches over everyone is UKGC, United Kingdom Gambling Commission. They make sure that every cog in the machine is doing what it should and that the player is getting a fair treatment.

The whole process takes many steps. Every single link in the chain needs to be checked and made sure that they work by the book. Simply put, to get a game to a player, the following needs to happen:

1. The developer needs a remote license
2. The slot needs third-party testing and a license
3. The casino needs an operating license

When all these are done, then you as a player can go and play the game knowing that everything is trustworthy. The game will not try to cheat you, the randomness is actually random and that the casino doesn't manipulate any results.

On Bojoko, you'll only find online casinos licensed by the UK Gambling Commission.

Can a slot licence expire?

Some licenses are valid until they get manually revoked. For example, a developer's remote license can be taken away if UKGC gets complaints and looks into it.

A slot's license on the other hand is not indefinite. They are good for a year or two, depending on the details. After that, the developer needs to reapply for the license. This is usually a walk in the park, as the game might have not been changed since the first license application. If the game has been updated in any way, then it needs to be looked over again by a third-party tester.

When a game goes to third-party testing, every single bit of it is looked at. At the time of this article, UKGC uses iTech Labs to test the slots. They go over everything, and I do mean everything. The slot needs to pass rigorous testing and even the source code of the game is analysed.

EXAMPLE: Twin Spin Megaways needed to comply with 28 different requirements to meet the licensing standards, including things like rules and artwork, RTP, functionality, result determination, transaction displays etc.

Some other games might even need a couple of more, depending on the features and what kind of a game it is.

All of this is done for you. If UKGC wouldn't keep a watchful eye over the developers and the casinos, they could offer any kind of games they wanted. No one would ever know if they were fair and that the player even has a chance to win anything.

FAQ

Online Casino Slot Uk

Online slots are the modern version of the physical slot machines you've seen in brick-and-mortar casinos. They are the most popular gambling games online and all UK-licensed internet casinos have them.

Online or internet slots have many advantages over the brick-and-mortar casino slot machines. These include:

• Bigger game selection
• Higher RTP = smaller house edge
• More betting options
• Bigger jackpots
• More features

Top Slot Games

The reels start to spin together and stop one by one. Whether you win or lose depends on symbols you land on the reels and the active paylines of the game.

You can see the paytable and rules for each slot by clicking the information button once you've opened the game.

We explain this in more detail above, in the section How do slots work?

No. However, online slots have a built-in house edge. In the long run, you're likely to lose more than you win while playing them. That's why every player takes a conscious risk playing them. Just like any other form of gambling, you shouldn't play with money you're not prepared to lose.

Slots are built to be as unpredictable and random as possible. Every spin is a random event, completely independent of the results of the previous rounds.

This unpredictability is powered by a random number generator (RNG). Every RNG in use on licensed markets such as the UK is tested and authorised by independent testing agencies to guarantee fair play.

To put it bluntly, there's no way to beat a slot machine. You can win, but it's all random and there's nothing you can do about it.

Some players believe they can determine when a slot is going to pay out. Others use different betting strategies to maximise their chances of winning. This is nonsense.

Slot machines have no memory and the odds stay the same from one spin to the next, even after a jackpot is won.

Instead, you can enjoy slots for a longer time without losing too much. Manage your expectations and your spending well in an online casino:

• Play for the right reasons. Gambling is a form of entertainment, not a way to make money
• Set aside a gaming budget you can comfortably lose - and stick to it!
• Keep your individual bets small relative to your overall gaming budget
• Don't chase your losses or raise the stakes after a bad run
• If you win big, withdraw your winnings

You'll find more info on our Responsible gaming page.

RTP or Return to Player is the payout percentage of the slot. Slots available in UK-licensed online casinos usually have an RTP of around 96%.

EXAMPLE: In a slot with an RTP of 96%, on average you win back £96 for every £100 wagered.

The RTP is an average that realises over the course of thousands of spins, meaning you probably won't win exactly £96 within a single game session.

Best Uk Online Slots

RTP can also be used to calculate the house edge, i.e. what are the odds in casino's favour. 100% - RTP% = house edge. In the example above, the house edge is 4%.

We explain RTP and the house edge in more detail on our Casino games page.

Volatility (a.k.a. variance) describes how much the game results vary between rounds.

Low volatility slots churn out small wins at a steady pace. High volatility slots give bigger individual wins, but you may have to wait for a long time between hits.

Volatility is the opposite of hit frequency: high volatility slots have a low hit frequency and vice versa.

Use our slot comparison tool to filter slots based on volatility.

When you play slots for real money, choosing the game is always a matter of personal taste. You may already have some solid favourites, but trying something new makes a world of difference.

These are the main factors to take into account when picking the best slots to play:

• RTP
• Volatility
• Minimum & maximum bet
• Special features
• Mobile usability
• Theme
• Jackpots
