How I ranked the top sites for the best payout slots

Many online casinos feature high-paying slots in the UK today. However, some are better than others. I considered a variety of factors when ranking the best sites for this type of game, including the following:

• Payment method variety – Players in the UK can use debit cards to place bets on slots. Meanwhile, PayPal, Skrill, Paysafecard, Skrill, and Apple Pay are among the other common payment methods accepted by online casinos. 
• Deposit and withdrawal times and limits – It is important that payments are processed quickly and securely. Meanwhile, many casinos feature deposit and withdrawal limits, with my recommended sites catering to beginners and high rollers.
• Mobile apps and accessibility – Top payout slots must be accessible on mobile, whether it be through your chosen browser or a dedicated app.
• License and security – My recommended casinos are all regulated in the UK by the Gambling Commission. Meanwhile, they also feature a host of security tools, such as SSL encryption and firewalls. 
• Customer support – Agents are generally on hand day and night to answer questions and deal with technical issues. Many of my recommended casino sites offer live chat support.
• Bonuses for slots and free spins – Part of the appeal of playing slots online is the bonuses that are on offer. Both new and existing players can take advantage of promotions, including free spins, reload bonuses, deposit bonuses, and cashback bonuses. 

A closer look at the casinos with the best payout online slots

I will now take a closer look at five casinos that feature high payout slots. For each, I’ve listed the main pros and cons:

1. Duelz

Duelz is another casino site that went live in 2018. With a welcome package worth up to £100 in bonuses and 100 free spins, I’ve always found Duelz to be an attractive platform, and I’ve never found it lacking for high payout slots.

The high-RTP games I’ve most enjoyed playing here come from Play’n GO, NetEnt, Pragmatic Play, Red Tiger and other leading slot developers. Real-money bets can be funded through Visa, Mastercard, PayPal, Skrill, Trustly and paysafecard. Elsewhere, weekly cash back, tournaments and Drops & Wins events help entice players into signing up at Duelz.

2. MrQ

A common staple of my casino recommendations, MrQ is an online casino launched in 2018. There are over 900 slots in total here, including some of the best payout games I’ve had the pleasure of playing. These include 1429 Uncharted Seas, Mental, Rick and Morty Megaways, and King Kong Cash.

Thanks to the no-deposit bonus, I received 5 spins as soon as I registered, and then another 30 after making my first deposit. Visa, Mastercard, and PayPal are accepted, and were quick to pay out when I managed to make the most of a high-RTP slot game. Of course, MrQ is regulated by the Gambling Commission, completely mobile-friendly, and recently released an official app, too!

3. Mr Vegas

Mr Vegas was launched in 2020 and is one of the best ProgressPlay Limited casinos I’ve had the opportunity to play at. With over 5,000 games in all, players will find thousands of slots. More importantly, I was super impressed by the prominent “Game payouts” tab, listing out exactly what you can expect from each game and therefore locate the slots with the highest payout potential.

I’ve tested Mr Vegas’ games from a large number of different slot providers, including Barcrest, Microgaming, NetEnt and Play’n GO. A 100% deposit bonus worth up to £200 is available to new players, with “The Wheel of Vegas” offering three exclusive jackpots. 

4. Winomania

Winomania went live in 2018. When I first registered on the site – and claimed the welcome offer worth up to £100 and 100 free spins to play with – I found slots from the likes of Play’n GO, NetEnt and Red Tiger. As such, players signing up can look forward to taking advantage of a host of slots with high payouts.

I was none too pleased to see that the Winomania Casino lobby unfortunately doesn’t allow for RTP sorting, which means I had to dig through individual titles to find the best payouts. Still, the games I did end up choosing and playing were excellent – and so were my winnings. Live chat support and other modern features are available too, so you can use that to ask for game recommendations, while a VIP program keeps existing players satisfied.

5. Magic Red

Established in 2014, Magic Red Casino is regulated in both the UK and Malta. I love a double-license casino, because that means it can cater to a wide audience, and Magic Red certainly can: There are over 1,000 games in total here, including hundreds of slots. The high-payout slots I played here come from NetEnt, Play’n GO and other top software providers.

The average RTP at Magic Red is 96%, while the vast majority of slots are accessible on mobile devices. A good range of payment methods are accepted, including PayPal, Skrill and Neteller – I used PayPal for both depositing and withdrawing. My first deposit netted me a bonus of £25, along with 25 extra spins, too, so that’s something new players can look forward to.

How to register at a casino and play the best payout slots

If it’s not quick and easy to register an online casino account and start paying high payout slots, you’re in the wrong casino. In my experience, the process follows this step-by-step guide:

1. Choose a casino from my reviews.
2. Enter the casino site on a desktop or mobile.
3. Select the “Register” or “Join Now” button.
4. Complete the registration form by entering the required personal details.
5. Enter a promo code if applicable.
6. Verify your account via the link found inside your welcome email.
7. Login to your account using your username/email address and password.
8. Browse slots, focusing on those with a high RTP.
9. Set your stake and place bets.

What is RTP? 

Return to Player (RTP) is the general term for the payout percentage of a casino game, whether it is by roulette, blackjack, slot machine, or other games.

The RTP is an important factor to consider when choosing between available slots. This is the term given to describe the odds of a machine, and the percentage of a money bet that a slot will pay back over time. For example, when I place 100x £1 bets on a slot with an RTP of 98%, I expect to make £98, on average.

While some slots will have a higher variance with fever than bigger spins, the RTPs of these types of slots will even out and give the same type of payout percentage that lower variance slot machines give. This goes for all types of slots, no matter the theme, how many also include special slots like jackpot slots.

What slots have the best return-to-player rate?

Some slots stand out because of their high RTP. Coming from a variety of software providers, the likes of Book of 99, 1429 Uncharted Seas, Blood Suckers, and Jokerize all come with an RTP of 98% or higher. While such casino games do not guarantee returns, they will appeal to many players with great excitement and good payouts. 

How can you check the RTP rate for slots?

This is a relatively simple process, if you know what you’re looking for, so I’m here to teach you. On most casino sites today, you can click/tap on the “Help” or “Information” button. Along with other statistics, you will see the Return to Player, displayed as a percentage.

If this option is unavailable, just carry out a quick search via your chosen search engine, see if, or visit the software provider’s website. If you are reading about the game in a review, it will most often also list the RTP. It is worth noting that if a slot is available at both land-based and online casinos, the RTP may differ between the two variants.

What are the advantages of the best-paying slots?

There are many benefits to playing high payout slots. Firstly, they offer better value money when you are successful. Meanwhile, an increasing number will feature in-game bonuses, making it easier to win larger amounts.

As well as being potentially lucrative, modern high-payout slots are also entertaining to play. This is due to their excellent graphics and gameplay. 

What are the disadvantages of payout slots?

As with any type of casino game, there are also limitations to speak of surrounding high-payout slots. Firstly, they may contribute less towards the bonus wagering requirements. On top of this, the large RTP means that you may focus less on volatility. If a game comes with a large jackpot, it will likely not pay out as regularly. 

Can you play the best payout slots on your mobile?

Absolutely! The best payout slots are all accessible on mobile devices. Dedicated mobile casinos allow players to enjoy the same number of games as desktop casino sites. The rules, gameplay, and bonus features are identical, it is only really the screen size that changes.

Can you play slots for free at UK casinos?

The short answer is yes. While playing for free in a land-based casino is not possible, it remains an option to play slots for free online. Easily accessible, demo modes and free spin offers are ideal for beginners and those just looking to play for fun. You will need to verify your age beforehand though, which will take a few minutes to achieve. Again, there is no difference in terms of gameplay. The only change is that you are not putting your own money at risk.

What are loose slots?

Simply put, the looser the slot, the more money it pays out. While the house edge remains with the casino, a loose slot does offer better returns. The loosest slots come with a greater-than-average payback percentage. 

What bonuses are available for the best payout slots?

Slots players are spoiled for choice when it comes to casino bonuses with many options available. Players will be able to claim bonuses such as cashback bonuses, free spins, reload bonuses, and more.

What is the biggest slot win?

In 2003, one lucky slots player in Las Vegas took home $39.7 million dollars from the Excalibur slot. Meanwhile, closer-to-home dad-of-three Michael Clark won £5.4 million.

Which casino has the best payout slots?

Mr Vegas casino has the highest amount of the best payout slots and also offers players fast withdrawals of less than 24 hours.

My top 5 tips for playing the best payout slots

Despite offering high payouts, there are no guarantees that you will make money from playing slots. The following tips will give you the best possible chance of achieving success in your chosen casino:

1. Play for free first – Where possible, play demo modes before wagering for real money. Free-to-play versions of most slots are now available in the UK, whether it be on desktop or mobile. 
2. Utilise bonuses – When the terms and conditions are favourable, take full advantage of available bonuses. Online casinos offer deposit bonuses, free spins, cashback and VIP rewards, which are all eligible to those playing high RTP slots. 
3. Be responsible – Set and stick to a budget! Remember to take regular breaks while never chasing your losses.
4. Consider volatility – The volatility of a slot shows how regularly it pays out. This is important to consider before placing bets. A high payout slot will likely come with low volatility. 
5. Play the field – There is nothing wrong with registering an account with multiple casinos. Doing so will enable you to play a large number of different slots, while also taking advantage of multiple bonuses.
