Still need some help navigating the best online slot sites? Read on to find out more as we take you through our criteria to not only finding the best but also the safest slot websites in 2024.

The Criteria Behind the Best Slot Sites

Trust and safety are at the top of people’s minds these days in all areas of online commerce and online casino slots are no exception. On our site, we only ever recommend casinos that are regulated and fully licensed to operate in the UK.

The best slots sites reviewed here provide a safe, secure, and scam-free environment for you to enjoy gambling in.

Fair and Safe Online Slots

Players fundamentally want two things from their online slots experience. First, they want reassurance the games they are playing are fair and second, they expect to be paid if they win!

Below we cover these two important aspects and how players can check if these safeguards are in place.

Gambling Site and Slot Game Licences

While we can’t guarantee you will win at any of the slot sites UK players can join, we can point you in the direction of licensed casinos that are required by UK regulatory law to pay out all winnings fairly and in a timely fashion.

If you do not choose any of our recommended slot casinos then you should always take the time to do your due diligence and check an online casino has the necessary licence. To do this, simply visit the Gambling Commission’s website and perform a quick search of the casino name.

Alternatively, simply head to the footer of any slot website and look for the licensing logo. On most, you should be able to click through a link and see its current licence status. Check out our Ladbrokes casino review for an example of an operator that ticks all these regulatory boxes.

Fairness Checked by Independent Auditors

Every piece of gambling software on the UK market must be thoroughly tested for fairness by independent third-party auditors. This is because software developers must be licensed as well as the online slot sites themselves.

By law, UK slot casinos must display the RTP of every game they offer ^[1]. If you are unsure what RTP means then we take a closer took at this metric further down the page.

Furthermore, online casino slots sites have their content checked by eCOGRA or iTech Labs – the leading independent and internationally approved testing agencies. It specialises in the testing online slots for customer fairness and safety.

RTP stands for Return to Player: an RTP of 100% would mean that every penny put into a slot is returned to players, so the closer to 100%, the less money players would theoretically lose over time. ^[2]

Be careful though, as this is a number worked out from millions of spins and not on playing sessions that are practically possible. The average RTP of a title at online slot casinos is around 96%.

Another indicator of how an online slot will play is its volatility. Essentially, this refers to the frequency of payouts. For example, the top 10 high variance slots will tend to produce higher wins less often while the best-rated low variance slots can be predicted to pay out more often but in smaller amounts.

Secure Payments When Playing Slots for Real Money

The best slots sites will offer a broad range of payment options and here we’ll take a look at some of the most popular. PayPal is by far the most commonly used from the selection of eWallets generally available. Its reliability and strict privacy measures ensure that it is top of the list for UK players.

Bank transfers and debit cards will always be popular when making transactions into online slot sites in the UK due to its high levels of security and two-step authentication procedures. There is a stable and steady number of online casinos that accept Visa.

With the exception of pre-paid cards, players can withdraw from any of the best online slots casinos using the same method as depositing.

Withdrawal times can vary but the top operator will typically pay out players within 48 hours. Now that customer identities are verified as part of the registration process, withdrawal delays are limited these days.

In general, no fees are charged when depositing or withdrawing but it is worth checking with your payment provider to be absolutely sure. Even some of the more innovative methods do not attract fees and you can even pay through your phone bill at Pay by Mobile casino UK sites.

Technical Security

Trust and safety are a major concern for all customers doing business online these days. All our recommended top slot sites have passed our stringent security check to ensure that your money and your data are protected while you play.

Other Features of the Leading Slot Sites

There are thousands of different slot titles all brought onto the market by a wide range of excellent software developers. The choice can be overwhelming, especially at casinos like Videoslots, where the number of slots reaches into the hundreds.

As we move on, we’ll also be looking at mobile compatability, the best welcome bonus offer, and examining the customer care of all our recommended slots sites.

The Slot Selection

Once you have verified that your chosen online casino slots site takes trust and safety seriously, you can start to consider its games portfolio. This comes down to individual player preferences.

The online slots market is known for its depth and variety, with a huge range of games all offering different playing experiences.

Some players prefer titles that replicate classic slot machine gameplay, while others might be more intrigued by the promise of free spins, bonus games and special features like best Megaways slots.

Either way, the best slot sites offer a rich diversity from the full range of different categories of online slots.

Types of slots:

• Online Slots: Enhancing gameplay with 3D graphics and special features such as wilds, scatters, and bonus free spins. There can be a huge variety in the types of themes from TV and film inspired games to Egyptian, the Wild West and sci-fi slots.
• Classic: These are your old-school fruit machine style games, offering little more than spin-and-win style gameplay. You’ll find the classic cherry, 7, and strawberry symbols in a three-reel, three-row setup. Simplicity and nostalgia are their primary features.
• Special Mechanics: Innovative game mechanics such as Megaways and Megapays are the latest ways to bring new life into old titles. Game developers must licence these features off the original creator.
• Jackpots: Progressive jackpot slots are a way of pooling prizes until one lucky player receives a huge jackpot. A small proportion of each bet is entered into a pool with potentially eye-watering winnings on the line.

The Best Features in Modern Online Slot Games

Classic slot machines have been a gambling staple for over a century, but the scene changed completely with the boom of online casinos in the early 90s.

Nowadays, online gamblers are spoilt for choice, with many innovative gameplay features which alter the playing experience significantly. Here are the best online slot machine features that UK casino players keep an eye on:

• Megaways Slots
• Megapays Slots
• Low Variance Slots
• Medium Variance Slots
• High Variance Slots

Of course, every UK online slot player will have individual preferences and strategies, so it is hard to say which is the best type of feature.

That is why most slot sites UK players can join have a diverse selection of types, or exclusive games. All these offer a pleasant diversion from the usual online slots on the market.

Pleas remember that no matter which type of online slot you play, winning is never guaranteed. Players should play within their means and always try to gamble responsibly.

Introducing Slot Game Developers

With such a huge variety of software on the market, you might be wondering where it all comes from. Most casino operators do not develop their own software but inestead offer games made by various specialised development studios, many of which have become legendary online gambling brands in their own right.

There are now hundreds of game studios in this sector of the industry, each offering their own vision for online gaming that is sought after by players worldwide.

This is why there is so much variety in the graphics, features and sounds. Below is a list of the leading slot providers:

Use Only the Best Mobile Slot Sites

Gone are the days where you can only play at slots casinos from your desktop. Nowadays you can enjoy the flexibility and convenience of playing on your mobile or tablet at any top mobile casino.

Whether you’re playing on the move, or simply getting away from a desktop or laptop computer, these days all online slots are designed to be played on a mobile device.

There may be some legacy slot games which provide optimal play on desktop but these are increasingly rare.

With the entire market shifting to mobile-first design principles over the past decade, players can reasonably expect to play almost any piece of software on their mobile devices. The top slot sites offer games portfolios that accomodate this expectation.

You should have no problem finding some great games out there, no matter what device you use. You can see some details about the best operators for mobile below, each offering slots bonuses.

Slot Site Welcome Bonus

In order to attract new players in a competitive market, operators will offer welcome bonus offers that often consist of bonus credits or free spins on a selection of their slot games.

Many players find bonuses helpful in making their gambling budget go further though many players these days focus on the quality of the overall content at slot sites rather than simply choosing the operator with the highest welcome bonus offer.

The most common form of online slots offer is a matched deposit bonus. As the name suggests, a slots casino will offer to match a player’s initial deposit up to a specified amount.

Be mindful, however, that these almost always come with wagering requirements. Read the terms and conditions of any welcome offer thoroughly before embarking on a bonus.

More relevant to slot players is the fact that high-limit online casinos typically offer welcome bonuses that focus on free spins. For these, you will usually be given a number of spins on selected games. Once again do check the terms and conditions carefully.

Any winnings that you make on these spins will need to be wagered a certain number of times before they turn into playable funds, but this type of bonus offer can work out much more favourably to the player than matched deposit offers.

Play Games for Free on the Best Slot Sites

On all the best slot sites, you have the opportunity to try out any of the games before playing with real money. You can make sure the game is right for you and you understand the nuances of gameplay features especially if they are new and unfamiliar.

When you play with demo credits as opposed to real money, the game plays exactly as it would if you were playing it at a real money casino, but obviously, you won’t get any of the winnings.

You can try them out for as long as you want. Even if you run out of demo credits, you can simply refresh and start again. That way you get similar fun without the risk.

Customer Support

Nobody wants to contact customer support, but when you do it is likely to be important. Therefore, having a competent, professional and knowlegable support team is important. All the slot sites listed on this page have demonstrated to us they can deal promptly and professionally with any issues that may arise.

A comprehensive FAQ and help section is a fundamental requirement. These knowledgebases are invaluable when it comes to resolving minor issues – there can be simple matters that need clarifying even at the best online slots casinos.

Other customer support options to look for before you play online slots are 24 hour live chat, an email address, a contact telephone number, and perhaps a contact form. You should be suspicious of any slot site which makes it difficult to get in touch.

Land Based vs. Online Slots

Slots didn’t begin in the digital format we know today: they have been a staple of pubs, clubs and land-based casinos for a long time.

Typically, the RTP of bricks and mortar slot machines is much lower when compared to online slot sites. This is because the overheads for running an online casino are much lower.

Although the range of games is increasing in land-based establishments, the limitations of physical space means they will never be be able to compete with the sheer variety and choice of online slots. Some operators offer portfolios that range into thousands of titles.
