How do we find the best slot sites?

When it comes to finding the best online slot sites in the UK, it’s all about who you know. Finding the best slot bonuses via GamblingDeals.com ensures that you are clicking through to the best slot sites, with the best new and existing slot bonuses online. But how do you know you are getting access to the best sites?

We have a team of people here at GamblingDeals.com that spend every day searching the web for the best slot sites. Once we come across a site that we like the look of, we carry out proper due diligence to ensure that they meet the high standards that we set. The slot sites that make our top UK list are those who share a mix of the common attributes outlined above. And importantly, we only work with UK slot sites that are licensed by internationally renowned governing bodies, like the UKGC.

How do we rank and compare the best slot sites?

Ranking the best UK slot sites is not an easy process. Several important factors need to be taken into consideration before we can compile our top sites list. Here is a breakdown of the things we look at when comparing the best online slots and sites. 

Welcome bonuses and existing customer promotions

There are three different types of slot bonuses that you will find on UK slot sites. Sometimes the best sites will combine these bonuses into one easy to digest welcome package. However, some sites will base their entire proposition around one type of bonus – here’s what you need to know.

Matched Deposit Bonus

Matched deposit slot bonuses are one of the most common forms of welcome bonuses out there. When you sign up with slot sites, you will be offered a matched deposit bonus that looks something like this:

• 100% Bonus Up To £300

This means that the UK slot site will match any funds you deposit up to the value of £300. For example, if you deposit £200 into the online slot, then you will get another £200 to play your favourite slot games. This means you have an initial betting balance of £400 to start your journey.

On top of this, some slot sites will give you even more funds to play with by increasing the matched percentage. Instead of giving you 100%, they will give you up to 300%. For example, you will be offered:

• 300% Bonus Up To £300

In this example, if you were to deposit £200, then you will get £600 in total to play your favourite games. This is one of the best ways out there to get tonnes of free funds to bet in the best UK slot sites when you join.

Free Spins

Free spins are another great type of bonus that the best slot sites offer. When signing up for an account, you will notice that you can access free spins on certain slot games as a way for you to spin the reels without risking your own funds. For example, you might see something like:

• 100% Bonus Up To £100 + 300 Free Spins On Book Of Ra

This type of bonus gets you 300 free spins on top of your matched deposit bonus when joining the slot site. In this instance, the free slot spins will only be available on the Book of Ra slot game. However, you will have 300 free spins to try your luck. That is absolute gold to any serious slot site player. UK sites will even give you free spin packages to use on any slot games across the site. These types of offers are certainly worth taking advantage of when you see them.

Wagering Requirements

When we evaluate the quality of a new player bonus, we always look at the wagering requirements that are stipulated. Wagering requirements are used by slot sites to ensure that bonus funds are not withdrawn from the site by new players before being used. However, some slot sites abuse their powers.

We are happy to see fair wagering requirements stipulated on new player bonuses as long as they are within reason and not designed to ensure that players have zero chance of walking away a winner when using their slots bonus.

Every slot bonus on GamblingDeals.com is shown alongside wagering requirements so that you can adequately assess the bonus before clicking through.

Slot game selection

The best slot sites are brilliant at compiling the best slot games online. They partner with all of the best game builders, including Microgaming, NetEnt, Playtech, and Novomatic. They ensure that their game sections include cult classics like Rainbow Riches, Age of Gods, and Starburst. Here at GamblingDeals.com, we don’t just review the best slot sites; we also carry out comprehensive reviews of all of the best slot games online. That gives us the unique ability to assess whether UK sites are bringing you the best games.

Slot Jackpots

It’s not only the best games that we care about seeing, and we want to know that you have access to the huge, life-changing slot jackpots. The best slot sites know that you are hunting for big payouts, that’s why they offer games which give you the chance to win big. Games like Mega Moolah pay out jackpots in the millions. What’s more, some sites offer games with progressive jackpots where the jackpot builds across many different sites. When we compile our list of the best UK sites, we always ensure that you’re clicking through to play chunky jackpots.

What are the other critical factors we assess at UK slot sites

Best Slot Sites:

How do slot sites work?

If you’re not sure how slot sites bring to market such amazing games, then let us clear things up. When you click through to join slot sites, you will notice that many of the slot games available on the site are similar to those on other leading slot sites. That’s because it is slot game makers who develop the slot games, they then lease them to slot sites which offer you the chance to play. What does this mean for you when you’re trying to find the best UK slot sites to join?

Well, firstly, you need to make sure that the site offers the games that you want to play. Some sites will only provide games made by one or two providers, while others will have a much broader range. What’s more, you will need to assess all of the other things that the site can bring. For example, do they have a wide range of deposit and withdrawal methods on offer? Do they have an excellent brand reputation with fantastic customer service? If so, then they’re worth checking out and signing up with. To find out which slot providers each site works with, check out our detailed slot site reviews.

Why should you join the best slot sites?

There are three big reasons why players play online slots. The first is that slots are a great way to play for life-changing jackpots. It’s not uncommon for players to win thousands (or even millions) of pounds when hitting slot jackpots. Some of the best slot sites online often have a range of games where the jackpot has run into the millions. While it’s not easy to hit the jackpot, the thrill of chasing life-changing money is unlike anything else.

Not only is it about chasing jackpots, but it’s also fun to play online slot games and grab great welcome bonuses. Here at GamblingDeals.com, we work with slot sites all day long to bring you the best slot bonuses and to connect you with the best slot games. In the last few years, there has been an explosion of slot games coming on to the market. New games like South Park Slots, Tomb Raider Slots, and Twin Spin are just a handful of great games that you can enjoy. What’s more, having the chance to grab a welcome bonus that provides you with the opportunity to play these games for free is a real buzz.

How much money can you win at UK slot sites?

Let’s provide some context for you. When it comes to the largest ever slot site wins, there are some massive numbers to shout about. The largest-ever jackpot win online happened on the famous Betway Casino. Jon Heywood was playing the popular Microgaming slot game, Mega Moolah. Little did he know that he was about to stumble onto the biggest ever slot sites jackpot win of all time. Jon bagged himself $20m in one single spin. Can you imagine the delight?

It’s not only Jon who has won big. Several players have become multimillionaires off the back of playing at popular slot sites. For example, one lucky Finish player who chose not to be named won 17m Euros off the end of a 25c slot spin when playing online with slot site, Paf Casino. His game of choice was the famous Mega Fortune, which was developed by award-winning developer NetEnt.

What are the best slot games available at UK slot sites?

• Cleopatra Slots – made by IGT, Cleopatra slots can be found on many of the best slot sites in the UK. Cleopatra has an RTP of 95.02% and allows you win huge multiples on your original stake. We love Cleopatra as it’s an old classic that reminds you of the Vegas slot halls of yesteryear

The RTP rate is high at 95.02%, and there is a chance to cash out with 2000x your original stake. That’s why it’s one of our favourite slot sites game

Can you join mobile slot sites?

Absolutely. When it comes to playing the best online slot sites, it’s vital that you can play on mobile. These days, if slot sites don’t offer you the chance to play via your mobile device, then they are not worth your time. The question instead is whether they provide you a mobile site or a dedicated mobile app. The best slot sites often allow their players the chance to download their mobile apps to play slot games on the go.

When you are looking to join your next online slot site, why not check out whether they offer a dedicated mobile app. If so, click through and get yourself signed up for an account before you download the mobile app. That way, when you click on to your iPhone or Android device to play, your mobile account will be ready and waiting for you. One of our favourite things about the best slot sites is that they always make it easy for players to play online slots while out and about and on the go.

Are slot sites safe to use?

Of course. Here at GamblingDeals.com, we only work with slot sites that are licensed by an internationally recognised regulatory body. In the UK, that body is called the UK Gambling Commission (UKGC). However, other leading institutions that slot sites are regulated by include the Malta Gaming Authority (MGA) and the Gibraltar Gambling Control (GGC) and others. Whenever you click through to join UK slot sites, or sites based overseas, make sure that they are regulated. That will ensure that they are operating in a trustworthy manner.
