What to Look For In a High Payout Slot?
When looking for a high payout slot to play, there are several things you should keep in mind when evaluating each slot title. Here’s a few things that we think you should consider:
High Win Multipliers
High win multipliers are the primary feature of slots with the best payouts, offering players the chance to significantly increase their winnings. These multiply a winning combination by a predetermined figure, dramatically boosting the potential payout.
Return to Player (RTP) Percentage
Another crucial aspect of any of the best payout online slots is the game’s RTP percentage. This figure indicates how much of the total money wagered on the slot is paid back to players over time. A higher RTP (usually above 96%) means the game is designed to return more to players, increasing your chances of winning in the long run.
Volatility/Variance
This measures the risk involved in playing a slot game. High volatility slots offer larger payouts that come less frequently, while low volatility slots offer smaller payouts more often. High volatility titles are typically considered the slots with the best payouts, but they require patience and a larger bankroll to handle the swings.
Bonus Features and Gameplay Mechanics
Slots with multiple bonus features such as free spins, multipliers, wilds, and scatters can increase your chances of a significant payout. These features not only make the game more exciting but also offer additional ways to win beyond the standard reel combinations. It’s essential to understand how these features work and how they can affect your winning potential.
Jackpots
If you’re looking for the best payout online slots, consider slots with progressive jackpots. These jackpots increase every time the game is played but not won, leading to massive payouts. However, winning such a jackpot is extremely rare, and playing these slots often involves accepting lower base game payouts.
Developer Reputation
The developer behind a slot game can be a good indicator of its quality and fairness. Established developers are known to create slots with fair mechanics and transparent RTP and volatility rates. Researching the developer can also give you insights into the game’s performance and reliability as well as its overall
Demo Versions and Free Play
Before committing your bankroll, try out the demo version of the slot. This allows you to get a feel for the game’s mechanics, bonus features, and volatility without risking your money. It’s an excellent way to see if the slot suits your preferences and playing style.
Choosing the right high payout slot involves a balance between the game’s RTP, volatility, bonus features, and your personal gaming preferences. We always encourage our readers to play responsibly, and set a budget to ensure a fun and sustainable gambling experience.
Gorilla Gold Megaways
With innovative design and multiplied winning possibilities, this video slot by Blueprint Gaming will surprise you.
Gorilla Gold Megaways’ highlight is the unusual design with four sets of reels distributed on the screen. The cubes are composed of 6×7 grids, each of them containing an additional 4-reel row as well. Part of the massively popular Megaways series, it’s no surprise its mechanics include up to 117,649 winning combinations.
This is a high-volatility slot, which means the rewards are big, but the hit frequency is lower. In the case of Gorilla Gold Megaways, there are additional bonus features that can better the odds.
One great feature of the games are the bonus spins, which you can activate by matching scatter symbols. The more scatters you get, the more bonus spins you will receive, up to a maximum of 35. By collecting tokens, you can also trigger the Super Spins round.
Animal symbles are the highest-paying symbols, up to 50x; while card symbols offer 1.5x multipliers. The maximum payout you can receive is 20,000x, and the betting range varies from £0.50 to £50. As with many of the best payout slots in the UK, Gorilla Gold Megaways has a scatter symbol, a shiny diamond.
Guns N’ Roses
The high-RTP slot with selectable soundtracks and free spins is a suitable choice for all music fans.
Guns N’ Roses ranks among the best payout online slot titles in the UK is. The electrifying vibrancy of the game is enhanced by the group’s most popular rock hits – Paradise City, Welcome to the Jungle, Sweet Child o’ Mine, and others. To suit your mood best, you can choose between five songs to accompany your gameplay.
The payout rate of the Guns N’ Roses slot is 96.98%, which is superb compared to many other games on the UK market. It has a 5×3 layout with 20 paylines in total. The logo of the game acts as an expanding wild, and the highest-paying symbols are the band’s members. Look out for Slash and Axl Rose!.
Guns N’ Roses’ has low to moderate volatility, so you will get the chance to make winning combinations more often. Their payouts won’t be the highest, but for that will compensate the bonus rounds. As it suits one of the highest payout online slots, Guns N’ Roses hides many extra features.
Legend Spins award stacked wilds, while a Solo Multiplier lands randomly and brings 4x to 10x for a winning bet line. The Encore Free Spins feature will give you up to 10 extra spins, and if luck is on your side, the Crowd Pleaser bonus game will start. You will have the chance to pass all three levels, choosing between mysterious prizes with cash rewards.
Reel Rush
Prepare for increasing paylines, a lot of free spins, and immersive gameplay with high levels of thrill.
Reel Rush takes third place among the best payout slots in the UK, with an RTP of 97.00%. NetEnt has outdone itself by creating a unique grid with expanding paylines. As you start the game, a diamond-shaped layout will appear and offer you 45 winning possibilities. With each successful combination, the grid will expand to eventually reach up to 3125 paylines.
The theme is based on fruits and candy symbols, the highest-paying of which is the strawberry – it will bring you a 1000x reward for five matches on a payline. The other fruits and sweets will grant you lower payouts, from 10x to 500x. Re-spins with increasing ways to win are the feature that ranks Reel Rush among the best payout slots in the UK.
This NetEnt slot distinguishes itself from the rest with cutting-edge graphics. You can also play the game on your mobile device – any iOS or Android smartphone or tablet with a recently updated operating system is appropriate. The minimum bet of £0.50 will suit low-rollers, while more experienced players can go up to £100 per spin.
Twin Spin
Don’t let Twin Spin’s simple layout fool you – it has some fresh tricks up its sleeve.
With 243 fixed paylines and a 5×3 grid, Twin Spins may not seem like the most innovative slot game at first glance. However, the Twin Reel feature adds a fresh twist to classic gameplay. The twin reels appear on two adjacent reels and can expand to three, four, or even five-of-a-kind.
To make a winning combination, you need to land three or more matching symbols on the neighbouring reels, starting at the leftmost reel. The theme of the game is in a classic Vegas style, and the symbols include cherries, sevens, bars, bells, and diamonds. The latter is the most rewarding and can bring you a payout up to 1000x your initial bet.
There is also a wild symbol, another characteristic of the highest-paying slots in the UK. You can adjust the coin value to suit your budget – from 1p to 50p. The game includes ten bet levels, and it requires you to play with 25 coins per level. The minimum bet per spin is 25p, while the maximum you can wager is £125.
To make your gameplay as relaxing as possible, you can turn on the autoplay function. Mobile play fans will be pleased to learn any hand-held device is compatible with Twin Spin. No progressive jackpot is included, but the high RTP compensates for this.
Genie Jackpots Wishmaker
Dive into the magical world of Genie Jackpots Wishmaker and try to make a winning combination.
Another candidate for the best payout slot in the UK, this Blueprint title is a medium-volatility casino slot that both low-rollers and high-rollers can take advantage of. The maximum bet goes up to £500, which gives you a fantastic range of betting options. If you want to enjoy the game for longer, you can bet as low as 10p per spin.
The theme is inspired by Alladin. You will discover elements like wild carpets, super-stacked genies, crossed swords, treasure chests, and books. Card symbols are also present in the form of A, K, Q, and J. The highest-paying is the wild carpet, which can bring you up to 500x your bet.
The RTP of the game is above the average and is a sign that you are about to try one of the highest payout slots online. The paylines are 20, which is also pleasing. There are 13 bonus features as well – re-spins, scatters, and wilds. The Win Spin round promises a winning combination, while the Genie Wilds can substitute for any other symbol.
Aloha Cluster Pays
Let the setting take you to Hawaii, where generous prizes are masked as palm trees, seashells, and pineapple fruits.
If a holiday mood is what you crave, Aloha Cluster Pays has a lot to offer. With an exotic beach setting to set the tone. The RTP of the game is 96.42%, which gave us good reeason to rank it sixth among the best payout slots online.
The layout of the game includes 6 reels and 5 rows. The innovation introduced by NetEnt is the absence of paylines. Instead, there are clusters – you can match symbols in any way, not only from left to right. That increases the winning potential significantly.
The Hawaii-themed slot’s highest-paying symbols are the multicoloured totems. The red one can bring you a payout of up to 10,000x of the value of your initial bet. Then, the green and blue totems have the same payout rates, with a maximum of 5000x.
Slots with high payouts are particularly attractive when they also offer bonus spins. With Aloha Cluster Pays, you can win from 9 to 12 bonus spins, and while the round goes, the Symbol Drop feature appears to make space for the highest-paying symbols by eliminating the lower-value elements.
Piggy Riches
Immerse yourself in the luxurious life of Piggy Riches and explore the banknotes, coins, and other valuables appearing on the reels.
Piggy Riches is another great title created by the award-winning software developer NetEnt. The payout rate is approximately 96.40%, which is very close to the previous slot we discussed. The volatility is medium, while the 15 paylines are adjustable. Piggy Riches’ grid is a classic 5 x 3, making it a good fit for beginners.
Piggy Riches is not a progressive jackpot game, but the free spins functions do add to potential winnings. To activate the bonus round, you need to match at least three scatter symbols represented by Mrs Piggy. She will reward you with a multiplier and up to 28 free spins.
The highest-paying character in Piggy Riches is the bag full of golden coins. By matching five-of-a-kind, you will win 2000x your initial bet. Other rewarding symbols are a golden credit card, a keyring, a wallet full of banknotes, and a piggy bank. Classic elements like card symbols are present as well and will bring you smaller payouts.
Starburst
Starburst’s cosmic ambience will introduce to you expanding wilds, alongside win-both-ways paylines.
Arguably the most popular slot in the UK, Starburst represents an arcades-style game with diamond-shaped symbols floating in the atmosphere. You will notice the return to player rate is also cosmic – 96.10%. Without a doubt, Starburst ranks amongst the most successful slot titles, with the best payouts.
The symbols you should look out for are the bars and sevens. The first one will bring you up to 250x your initial bet (for five-of-a-kind). The second highest-paying symbol is the sevens. Match five of them, and you will get a payout of 120x. Yellow, green, orange, blue, and violet diamonds are the lower-paying characters.
Unlike other of the best payout slots in the UK, Starburst has no free spins or a bonus round built into its mechanics. Instead, it offers expanding wilds, unique symbols that appear on reels two, three, and four. Consecutively, they multiply to cover the entire reel.
Avalon
Learn the legend of King Arthur and try to multiply your winnings by benefiting from free spins and gamble rounds.
While navigating through the Microgaming casino platforms, it was inevitable not to include Avalon in our list. The tale of King Arthur and his knights comes alive in this high-RTP slot. With a payout rate of 96.01% and 20 selectable win lines, Avalon promises excellent winning opportunities for all UK players.
Like most of the highest payout slots, Avalon also offers bonus features. By activating the gamble option, you will enter a bonus game that will let you try and double your winnings. The Lady of the Lake appears as a scatter and can reward you with up to 12 free spins. In addition, she can also multiply your prize by up to 7x.
The Avalon symbol is the wild and substitutes for all others except for the Lady of the Lake. During the free spins round, the treasure chest acts as a wild symbol and will replace all other characters except for the scatter. The minimum bet per spin is 20p, while the maximum is £200. The maximum win you can receive is 420,000x your initial bet.
You can play the game on any device, desktop or mobile. As with many of the UK’s best payout slots, Microgaming has optimised this title for mobile performance, so you can enjoy playing this game on the move.
Gonzo’s Quest
Enjoy the 3D graphics of the most adventurous among the best payout slots in the UK -Gonzo’s Quest.
Compared to the slots with the best payouts, the RTP of Gonzo’s Quest is slightly lower – 95.97%. Nevertheless, this is still an excellent percentage. The volatility is medium to high, meaning winning combinations can be less frequent but potentially larger.
Apart from the standard 5×3 grid, the slot features 20 paylines. An entertaining and rewarding feature is the avalanche. It activates with any winning combination, making the matched symbols explode. New symbols fall down and replace them, which doubles your chances of enjoying another successful round.
The avalanches will keep going until no more winning combinations appear. You will also get multipliers as you play. The betting range varies from 20p to £200, giving you enough flexibility. Gonzo’s Quest doesn’t include a progressive jackpot, but the mechanics have a wild symbol that substitutes for all others.
We believe you will enjoy the storyline behind Gonzo’s Quest greatly. It will take you on a search for the lost city of gold, El Dorado. The setting is in the Peruvian jungle, where Mayan gods and creatures guard the hidden treasures.
What Are Slot Payout Percentages?
The return-to-player (RTP) is a figure stating the theoretical percentage of your betting total that you would get back on a long-term timescale (typically measured over 10,000 games or more). Under UK regulatory law, all casino slots’ RTPs must be certified by independent third-party auditors and have these percentages published, so players can check them before they choose a game.
As an example, if you bet £100 on a slot game with an RTP of 95.00%, this means that over a long enough time span you should win back £95 while playing. However, this figure is meant to represent the overall fairness of the game and the house edge, and is not an indicator of your expected outcome while gambling. RTP figures are useful for choosing a game, our general advice for new players is to stick to slots with the highest RTP.
The highest payout online slots typically have an RTP of over 96.00%, while average payouts are between 92.00% and 96.00%. Low payout rates are below that, going down to 88.00% or lower.
Compared to other casino games, slots have a slightly lower payout percentage. Even the best payout slots in the UK hardly reach the RTPs of blackjack or roulette. However, if you learn to distinguish a good payout online slot by examining its game mechanics, you have a satisfying probability of winning.
A great starting point is visiting the best RTP slot sites and exploring their game libraries. You can check for the titles we suggested and choose the one with the most bonus features. Claiming a welcome bonus can also help but make sure the wagering requirements aren’t too high.

Most often, there are some requirements to fulfil in order to claim a bonus. You must register and make your first deposit, which is usually a minimum of £10 and £20. Wagering requirements apply even on the best casino bonuses in the UK. Sometimes, there are also caps on winnings made with bonus money. We advise you to read the terms and conditions carefully.

On the cashier page, you should have at least several trusted payment options, including debit cards, e-wallets, and bank transfers.

Before you send a payout request, make sure you have verified your account in advance. If you’re a verified customer of one of the UK’s online real money casinos, you should expect timely withdrawals with your chosen payment processor.
When it comes to maximum withdrawals, UK operators have no constraints. However, some payment providers may have restrictions, which is why you should take your time to learn about the policies of your preferred e-wallet or online banking service.
Advantages & Disadvantages of High-Paying Slots
- Better Winning Potential
- Great Variety of Games
- Wide Betting Ranges
- Suitable for Mobile Play
- First-Class Software
- Higher Potential Risk
- Winnings are Luck-Based
- Not in Every Casino
Our overall opinion on the high payout slots for the UK market is positive. We note a wide range of choices that suit all players’s preferences. When it comes to game diversity and features, the best software developers have taken care of creating exceptional gaming experiences with multiple winning opportunities.
High payout rates combined with bonus features like multipliers and free spins, means potentially greater winnings. The downside is that the result depends on your luck rather than your skills. You should also evaluate the slots according to their volatility. You can learn more about this topic in our guide to high variance slots online.
Another drawback is that some of the best payout slots online in the UK are often excluded from casino bonuses. If they are included in the promotional terms, they might have lower contribution rates, and the bonus wagering requirements might be harder to fulfil.
Always go for bonuses with playthrough requirements that are realistic to complete. For example, a low-wagering casino in the UK would offer promotions with wagering from 15x to 35x. Don’t settle for conditions that are not to your advantage.
