The best way to find a trustworthy online casino is to pick a big online casino with a large number of players and big revenues, which we’ve given a high reputation rating. Large casinos are generally safer for players, because they have big revenues which allow them to easily pay out players even if. But you know what’s people like the most? Certain video slots pay-out big time! Because we like to help our readers, we made a special selection of the best paying video slots. In our selection of best paying video slots you will find all popular video slots that have a great pay-out percentage according to our partner Videoslots.com!
When you’re searching for the loosest slots online, you might be looking for specific fruit machines which pay off at high rates. The only problem with this method of shopping is the payouts can be changed from time to time, so you might not always be getting the best bargain, if you have dated information. I’ve found the best way to shop for good gambles online is to find the online casino websites which consistently pay out the most. From there, finding a slot machine with good pay out percentages should be child’s play.
Understanding The Payback Percentage
If you’re brand new to the online casino game, you might wonder what an expected payback or a payout percentage is. An expected payback is how much you expect to be paid back when you bet a theoretical amount of money. Let’s assume $100 is the standard amount you bet. If a casino has a 98% payout percentage, then you should expect to be win back $98 for every $100 you wager. If you see a 93.5% payout percentage, you’d expect to win $93.50 for every $100 bet. If you saw a 101% payout percentage, you’d expect to pocket $101 for every $100 you gamble. Anything at or over 100% is unrealistic, of course, because the house edge is how a casino stays in business. You should note that the house edge is the amount the casino expects to win on a $100 bet. In the previous examples, you subtract the expected payback from one-hundred percent to get the amount you expect. So in the examples, you would have a house edge of 2%, 6.5%, and no house edge at all.
Of course, the average payout percentage and what happens in a real sessions of slots can be far apart. The deviation on most slots games is often large. One person with a 96% expected return might win $50, while another person might lose $58. This would add up to the expected 96% return, but these two players would have to wildly different results. The longer a person plays and the more spins that happen, the closer you would expect the results to be close to the house edge. The larger the volume of players in both live casinos and online casinos, the more likely the casino management’s house edge is going to make them rich. When you’re a gambler wanting to play the odds, you want to find the games and casinos that pay back the most. That increases your odds of winning, though nothing is ever certain.
Published Payout Reports Can Help Find the Loosest Slots
Occasionally, online casinos are required to publish their payouts to the public. This lets gamblers know which casinos are offering the loosest slots online–or any other game, for that matter. Once again, this can deviate a great deal from one day to the next, one month to the next, and one year to the next. That being said, given the volume these various gambling sites see in a given month or year, analyzing the statistics is a good way to see which ones are offering the best games. Most of the casinos I’m going to talk about bring in tens of thousands of gamblers per month, so unless these guys have given up huge progressive jackpots that cause major deviations in the numbers, this should be a pretty good indication which ones offer loose fruit machines and which ones don’t.

Microgaming Casinos with Loose Slot Games
As late as August 2011 (the last time published reports came out), Microgaming had a stranglehold on the best payout percentages in the online slots industry. The #1 casino was Mummy’s Gold Casino, which had average published slots payout of 96.90%. Three casinos had better overall grades, with bet365, Ladbrokes, Intercasino, and Royal Vegas Casino offering total payouts (on all games) of 97.35%, 97.25%, 96.99%, and 96.98%. If you only look at the slots statistics, each of these casinos offered worse odds than the Mummys Gold Casino, though.
What’s probably most important to take from this report is that Microgaming slots had the best payouts on whole. Of the casinos so far mentioned, all were powered with Microgaming online casino software, except for Bet 365 and Intercasino, which use Playtech and Cryptologic, respectively.
Other Microgaming slots casinos that were among the top contenders were Lucky Nugget (96.46), Casino Action (96.17), 32red (96.05), All Jackpots Casino (96.03), Jackpot City (96.02), Spin Palace Casino (95.77), and The Gaming Club (95.27). Once again, these are a snapshot, not the full story. Each involves analysis of one month. For instance, I’ve always had better luck at All Jackpots or SpinPalace than some of the other listed casinos, but that might be my experience.
More Loose Slot Machines
The Microgaming sites weren’t the only ones surveyed, as mentioned above. William Hill Casino uses Playtech, but they only paid back 94.26%. The last time I saw this list, William Hill was closer to 97% and was ranked third on the list, so expect some deviation. Party Casino with its Party Gaming software did worse at 94.23%, while 888casino had an awful 92.11% payout percentage. If you’re playing against a house edge of 7.89%, you won’t have your bankroll for too long.
Specific Slots to Play with the Best Payouts
If an analysis of the slots casinos isn’t enough for you, I’ll give you a list of online slot machines with good reputations for the best payouts. Microgaming slots like Thunderstruck, Cash Splash, Ladies Night, and Double Magic all have good reputations. Playtech has games like Diamond Valley and Captain’s Treasure which are considered good. Mid-Life Crisis Slots from Realtime Gaming is another good option, if you want loose slots.
Don’t be fooled by bells and whistles. Many times, gimmick games are used to draw in the unaware. Those games which seem to have less frills often tend to pay out more. For instance, if you play a game like Double Magic, it might not seem like much to look at, but it’s popular because gamblers like it’s expected return. Also, if you’re looking for progressive slots with big jackpots and lots of action, you’re likely to be disappointed. To save up for that huge progressive jackpot prize, these slots have to take a lot of money from a lot of gamblers first. When you’re giving away $10 million to one person, you have to take $50 to $100 from a lot of other people. So if you’re looking for the loosest slots online, try to shoot for around 97% payback percentage and games without the biggest jackpots and most features. These are the games which should give you the most winning action.
Being tight is rarely an attractive trait, so the Professor has searched far and wide for the best payout online casinos that the industry has to offer.
It’s taken him some time, but he’s managed to sift through all the casino sites in his arsenal to bring you the top outfits. From his analysis, three distinct categories have appeared: casinos online with the best payout rates, fast payout casinos, and slots with the highest RTP.
The Prof made sure to include some of the best online casino reviews UK to satisfy British demand – but don’t worry, they are all available in several other countries too.
If one of these categories has already jumped out at you, select it from the list below to be taken to it down the page.
If you’d rather be given the full picture, read on for our guide to the best casino payouts!
Best Payout Online Casino – How is it calculated?
Some casino sites publish data from a given month which outlines their average return-to-player (RTP) percentage for that period. The way it works is different from calculating slot game RTP, with the Professor explaining how.
What is a casino’s RTP? The return-to-player percentage for casinos is a figure that’s calculated by dividing the total amount won by the total amount wagered during a particular period. It is based on actual real money which makes it a good statistic to consider when choosing a new site to play at.
NOTE: this figure provides merely a guideline of the best payout rates at online casinos. You should not expect to receive that exact percentage when you play!
To ensure every return-to-player checks are credible, the tests are conducted by third-parties rather than the sites themselves. While there are many such independent testers, all of the RTP certificates you’ll find below are issued by eCOGRA – a leading agency in the field.
Yet, the Professor realises that it would take a long time to trawl through all the options to see who has the best/highest RTP rate. So, he decided to pick out his top 3 – starting from the lowest to the highest.
Best Online Casino Payouts – Our top 3
888 – 96.61%
EXCL: 30 Free Spins
If you’re ever looking for a top online casinos UK list then 888 will often be included as an entry. However, they also happen to be one of our top payout casinos with an RTP of 96.61% for all games.
If there is a particular set of games – such as slots, roulette, blackjack or other – that you like to play the most, you can check 888’s Payout Percentage Report for a more focussed result for your preference. Also found here are blackjack and roulette randomness reports.
Simply navigate to the bottom of a main 888 page to find eCOGRA’s Safe & Fair badge.
Aside from the UK, 888 operate in numerous other regions – so many, in fact, that it’s impossible to list here!
32Red Casino – 96.86%
-
£10 Deposit = £32 Bonus Cash (up to £160)
Next up is 32Red, who have managed to attain a 96.86% return-to-player percentage.

A quick glance at their website also brings up a whole host of accolades dating back years, with 32Red scooping their first award back in 2003.
You will find only Microgaming slots in their library – which can go one of two ways. However, in terms of fairness and security, there are few that reach 32Red levels.
32Red offer their entertainment to many countries – such as the UK, Germany, Canada and more.
Videoslots – 97.78%
-
100% up to €/£200 + win up to 4200 FS
But our top highest paying casino is currently Videoslots – with a cool 97.78%.
Alongside blackjack and roulette, eCOGRA have awarded a randomness report for the Microgaming Video Poker games found here too – with the third-party auditor describing Videoslots as using the “best practice standards”.
Considering the sheer number of games available (3,400 and counting), this adds extra fuel to the already towering fire of Videoslots credentials.
Aside from France, Spain and a few other territories, Videoslots is mostly open to gamers.
Fast Paying Casinos
10 Free Spins
EXCL: 40 Bonus Spins
1 x Wheel of Rizk - Win Spins or Cash!
This is a slightly tricky topic to navigate, as the fastest paying casinos all have to rely on third-party payment processors. However, the very best usually offer the same methods – such as Skrill/Neteller/card/bank transfer – so the Professor thought he’d angle this category in a different way.

Before withdrawal requests are processed, they have to be approved first. You’d think this would be a piece of cake, but some decide to make this a long-drawn-out affair.
As such, the Prof decided to pick the fastest withdrawal casinos based on approval rates. Coincidentally, all of the below also happen to be PayPal casinos:
- Rizk: Within 1-4 hours!
- Unibet: Within 24 hours
- Mr Green: Within 48 hours
As long as you use the eWallet method, or something similar, then any winnings will be in your account in a matter of hours once the transaction has been authorised. No more waiting around for weeks on end!
All of the above are some of the fastest withdrawal casinos in the UK, but they’re also open to many other regions too.
Best Payout Slots Online
Contrary to common belief, online slots can and do pay – but you have to understand the maths behind it to see why.
Earlier we took you through what casino return-to-player is, but this is a slightly different concept.
What is slot RTP? It is one of the ways that a slot developer demonstrates the average odds of winning a prize. If a slot game has an RTP of 97% and you wagered £100 over a long period of time, the long-term theoretical payback amount would be £97.
Unlike casino return-to-player which is calculated by taking real money wagers and wins, slot RTP is a figure that’s calculated generally by playing either a compensated or random game 10,000 or 100,000 times respectively (UK Gambling Commission – Gaming Machine Payouts: return-to-player).
NOTE: Although the return-to-player percentage for slots is calculated differently to casino RTP, it should still be used as a guideline when selecting a game. As such, you should not expect to receive the given percentage back every spin/hand/round you wager.
Now, if you thought there were a lot of gambling sites, the number of slots and casino games will knock you for six – just look at Videoslots’ library! However, the Professor is well aware of those with the highest RTP, and therefore the online slot machines with the best payouts…
Starmania – 97.87%
Again, we’ll start from the lowest to highest, but Starmania’s RTP of 97.87% is hardly low in reality.
Produced by NextGen, this late-2015 release uses a pretty standard slot theme of colourful shapes and soothing sound effects.
Alongside the high return-to-player, you’re given the chance to gamble every single winning line you make. You can either end of empty-handed see your winnings quadrupled, or something in between.
Bloodsuckers – 98%
An absolute all-time classic, NetEnt’s Bloodsuckers has an RTP of bang on 98% – and it continues to rack up spins despite being released in late-2013.
Alternatively stylised as Blood Suckers, this haunting tale was such an exhilarating addition to gaming libraries that players immediately demanded it to be ported to mobile casinos once the smartphone insurgency took over.
NetEnt duly delivered, meaning you can always guarantee plenty of exciting casino bonuses and promotions around Halloween time.
1429 Uncharted Seas – 98.6%
Just a few months after Bloodsuckers came 1429 Uncharted Seas – with its 98.6% RTP.
Developer Thunderkick had only been around a year or so before they dropped this smash hit, but everyone definitely remembered their name afterwards!
Even more impressively, there’s also the opportunity for you to net up to 50 free spins as part of the game’s special features.
However, 1429 Uncharted Seas continues to be popular for one reason – it’s still to this day the highest return-to-player video slot that’s playable…
Jackpot 6000 – 98.86%
But what does that mean for the final two top RTP slots?
Well, we’re referring to Jackpot 6000 and the upcoming Mega Joker as classic slots – with the layout structure reducing to 3 rows and 3 reels. But it’s the inclusion of real skill that’s most interesting.
One thing to clear up first is that if you play with 1-8 coins then the RTP will drop to as low as 74.9%. However, wagering 10 coins will boost this up to the maximum potential of 98.8%.
This fluctuation is because of the Supermeter mode – which can only be accessed when playing with 10 coins. If you manage to enter this level, you can influence the result to try and make it land in your favour.
Mega Joker – 99%
However, ever since late-2013, the highest RTP slot ever has been Mega Joker with 99%.
NetEnt again incorporated skill into this game using the same Supermeter as Jackpot 6000 – with 10 coins needed for this feature to be possible. Any bets of just 1 coin will see the return-to-player rate drop to a lowly 76.9%.
Best Paying Out Online Casino Movies
Despite the graphics looking worn compared with the flash new slot games of today, Mega Joker will always be a nostalgic favourite. And with such a high theoretical return, it’s unlikely to be knocked from the top any time soon.
Fancy giving these games a spin? You just need to keep in mind one thing!
Most casino sites don’t allow you to complete wagering requirements by playing slots with the highest RTP. Why? Because they are deemed to reduce the house’s edge too much in the player’s favour.
