To find high-RTP casinos, you need to choose one of the selected online casinos on this page. A casino might offer the best RTP version of Starburst, but a mediocre RTP on Gonzo’s Quest, both slots from the same game provider. Finding high-paying UK casinos is challenging, as you need to collect data from thousands of slots at a specific casino to determine the average RTP on offer.
Like Mega Joker, the top RTP is locked to Supermeter Mode, and NetEnt also offers a 95% version of this game. The gamble feature adds upside when free spins are slow to arrive, which is worth keeping in mind given the game’s low to medium volatility. The medium volatility makes this the most balanced 99% slot on the list, and the built-in strategy online casinos UK indicator adds a layer of timing that most high-RTP titles don’t offer.
As mentioned earlier, Mega Joker and its 99% RTP offers a progressive jackpot as well! These low RTPs are balanced by the possibility of winning some huge jackpots, but you’ll obviously need a lot of luck to get that sort of prize! This means that unless you win the big prize, you’ll lose a small percentage of every wager you place. For example, a 97% RTP means that, on average, the slot pays back £97 for every £100 wagered. Developers use random number generators (RNGs) to test payout ratios across all possible outcomes.
With more than 96,000 prizes available every week, it gives players the chance to potentially enhance their playing time on Pragmatic Play slots. These online slots pool contributions from players across multiple slot sites, creating prize funds that grow continuously until won. Video slots have become the dominant offering at nearly all slot sites and make up the majority of slot games available to play. Most slot sites carry classic titles such as Fire Joker and 7s on Fire, which appeal to players seeking straightforward gameplay without complex bonus features. Bettors will find over 3,000 of the best online slots housed on the Ladbrokes app and my research discovered that fellow bettors were big fans of its range of daily free-to-play games and regular slot offers.
RTP can usually be found in the game info panel (“i” icon), the slot’s paytable, or the casino’s help/support pages. High RTP slots must be at the top of your list when you want to stretch your bankroll or clear a massive bonus. Yes, high RTP games are statistically better than their lower-payout counterparts.
The free spin rounds with additional wilds helps you reach the 1,000x max win. In the same vibe as Mega Joker, this slot is super simple, without many features. A 98.6% RTP combined with a lowe maximum win (670x), but low volatility ensuring frequent wins. Free spins on Big Bass Bonanza, worth 10p each. Time to deposit/wager 7 days.
Pragmatic Play slots are featured on all the top slot sites, the majority of which also carry the big-money slot tournament Drops & Wins from Pragmatic. Within the gambling world, I specialise in sports tips, event predictions and reviews of betting sites and online slot sites.

With thousands of weekly prizes available, just from playing some of the most popular online slots in the UK, it’s easy to understand why it’s so popular. Megaways have proven extremely popular on slot sites due to the games typically offering above-average RTP rates exceeding 96%. The best slot sites now dedicate entire sections to these dynamic games, which feature up to six reels with variable symbol displays, creating anywhere from 64 to 117,649 potential paylines. The most reputable slot sites offer tiered progressive systems through games like Mega Moolah, providing multiple jackpot levels. Progressive jackpot slots represent the pinnacle of high-stakes online slots gaming, with the best slot sites offering jackpots that can reach millions of pounds.
The Mount Olympus Free Spins feature awards a minimum of 15 free spins, with retriggers possible by landing three scatters. Gates of Olympus is the best Virgin Games slot for multipliers, with random multiplier symbols up to 500x that combine during tumbles. This underwater-themed slot title features 10 paylines that pay out up to 2100x your stake or £525,000 with a 96.71% RTP.
Immortal Romance is the best Virgin Games slot for bonus variety, featuring 4 different free spins bonus rounds through its Chamber of Spins system. This Relax Gaming steampunk Western slot offers a maximum win of £250,000 (5,000x stake) through its unique Bonus Reels mechanic. That said, payout rates can vary month to month, so we’d always recommend checking the casino’s published payout data before you play.
Don’t put all your eggs in one slot machine basket. Every percentage point matters when you’re talking about hundreds or thousands of spins. Avoid these like a timeshare presentation. But here’s the kicker – within the slot category, RTP varies dramatically. You might hit a jackpot on your first spin or lose your entire bankroll – that’s the nature of gambling variance. Let’s dive into the world of RTP and discover how to make your money work smarter, not harder.
At the end of the day, unless you’re going to be playing a huge number of game rounds, the actual RTP you will achieve is very unlikely to be anywhere near that which is advertised. While RTP should be considered a great benchmark when evaluating a slot or casino game, volatility should also be taken into consideration. Now you’re armed with the right information, you will be able to make smarter choices when it comes to choosing which games to play. Playing by these rules, you can expect a 99.5% RTP, making it one of the highest-paying RTP games available in a casino.

The Return to Player of jackpot 6000 is a little lower compared to the slots we have already spoken about at 98.86%, but you do not have to play Jackpot 6000 on Big Bet Mode to get this RTP. In addition, Book of 99 is a rather rare slot game, but it is available to be played at Casumo Casino. I have played and tested each of these slots myself in order to provide you with real evidence and expertise of what these slots are like to play. All casino games have a slight house edge which means the odds always favour the casino. High RTP slot games are the games with the lowest house edge. If you enjoy high-volatility slots with the potential for massive payouts, a lower RTP might not deter you.
On the other hand, a fast payout casino is one that gives you quick access to your money when you want to cash out. There also need to be fair maximum bet rules when players are trying to meet the wagering requirements, and fully transparent and easily accessible T&Cs. At WhichBingo, we think this means Welcome Bonuses with low wagering requirements and being able to play high-RTP games when clearing the playthrough.
From classic table games like roulette and blackjack to modern video slots and immersive live dealer experiences, every UK online casino offers something unique.

It can also be easy to get carried away and chase losses or spend more money on bonus buys than initially planned, or if you had played the slot without using the bonus buy feature. It uses a retro theme and is superb for players looking for high-volatile action with great max win potential. Top Dawg$ is the favourite Relax Gaming slot among many players, including the Relax team themselves, as informed during our exclusive Relax Gaming interview. This slot also allows players to buy their way into the Free Spins.
That’s because players usually prefer not to install casino software on their devices.

Trustly deposits are seamless, and combined with e-wallets like PayPal or Skrill, withdrawals often reach players within just a few hours.
