The Best Payout Slots For UK Players in 2024

Written by Jamie Wall

New online slots appear every few weeks. Unsurprisingly, game developers eagerly compete to produce the top titles. According to the November 2023 UKGC Industry Statistics report, slots generated £3.2 billion of the total casino revenue; over half of this sum came from their online version. Knowing where to find and how to win the best payout slots, in turn, makes a big difference in players’ revenue. This guide provides information on slot machine payouts, the best slots right now, and how slots compare to other games.

Covering the Basics: Slot Machine Payouts and RTP Explained

The first coin-operated gambling machines, dating back to the 1880s, were novelty items rather than serious gambling tool — a far cry from the online slot industry as we know it now. Today, slots have gained some innovative features, increased their payouts, and got RTP rates.

Understanding RTP rates before you play is important since, roughly put, they indicate the money you might get in case of a winning reel combination. This data lets you decide whether the game will likely provide consistent returns. It thus gives you enough insight to manage your bankroll accordingly.

These payouts are determined by the machine’s paytable, which outlines the combinations of winning symbols and shows the corresponding prize for each combination. Higher RTPs mean slots will return a larger portion of your wager, making it a more profitable option. Lower RTPs return less of your wager over time.

For example, if a slot has a 97% RTP rate, it should return £97 for every £100 you wager. This is better than a slot with a 95% RTP rate, which only gives £95 per every £100 wager.

RTP rates are typically set by game developers rather than the casinos themselves, meaning the RTP for a slot game should be the same across all regulated online casinos.

However, it might be different with unlicensed online casinos, where the accuracy and fairness of RTPs cannot be verified.

It’s worth mentioning that the method of determining RTP has recently shifted towards allowing RTP ranges. This change means that casinos can modify the RTP within a predefined range determined by the game’s designer. Furthermore, casinos are permitted to alter the odds of any machine up to a legal maximum defined by the gambling regulatory authority.

It’s vital to note that the RTP is a long-term average; therefore, the outcome percentages aren’t stable in the short term. They’re calculated over millions of spins, and for most players, a gaming session is usually much shorter.

You can find the information on RTP rates in the slot’s information help section (usually under the ‘i’ button) or by consulting the paytable. Best payout online casinos also list the RTP information under each slot description.

In addition, slot payouts are affected by the game volatility. High-volatility slots can provide infrequent large payouts, and low-volatility slots give smaller but more consistent wins.

Now that you’ve done your slot machine housekeeping, let’s move on to the best payout slots in the UK.

Add These High-RTP Slots to Your Online Casino Bucket List

The best payout online slots in the UK come in all shapes and sizes. From quirky storylines to unique reel mechanisms, there’s plenty to explore here. However, they all have one thing in common: reliable, fast payouts. Our experts have gathered the best 15, ranking them from highest to lowest RTP, and grouping them by the arithmetic average of each slot’s RTP rates from the most common British casinos.

Ugga Bugga — 99.07%

First on the list with a staggering RTP rate of 98.74% to 99.07% is Ugga Bugga by Playtech.

Released in 2013, this slot machine offers a tiki jungle theme with colourful graphics, jungle music, and themed symbols. The maximum prize on this slot is 1,000x your stake, but only when you land three Wild symbols on a payline.

Surprisingly, this high-rank slot doesn’t have many bonus features. It looks like Playtech was more focused on developing the gameplay mechanics. Ugga Bugga has ten fixed paylines, which are dispersed into 3×1 rows.

This slot is ideal for low-stakes players, as even at its lowest fluctuation, the RTP is above 98.5%

Book of 99 — 99%

Developed by Relax Gaming, Book of 99 is another excellent slot with a 99% RTP rate. This option is themed around Greek mythology: expect fantastic visuals in an Odyssey-like storyline.

Book of 99 was released in May 2021. It’s newer than other picks on this list, but that doesn’t mean it’s not widely available. You can find this on most UK online casinos.

What sets Book of 99 apart is its many bonus features and free spin deals. This is the one to note if you’re googling ‘online slots fast payout’ or looking for games with generous bonuses.

Jackpot 6000 — 98.8%

Another NetEnt entry, Jackpot 6000, has an astonishing 98.8% RTP rate. Unlike the previous option, this was released a little later in 2014.

Jackpot 6000 is another traditional-style slot machine with an easy-to-navigate format, plenty of wild symbols, and a ‘Supermetre’ bonus round where players can raise the stakes for higher rewards. There’s even a double-or-nothing feature which elevates the entire game.

1429 Uncharted Seas — 98.5%

1429 Uncharted Seas is a 98.5% RTP slot from Thunderkick. You’ll find it on most British online casinos.

The overall theme of 1429 Uncharted Seas is the exploration of the briny deep surrounded by detailed maps and mythical sea creatures.

Blood Suckers — 98%

Next up is yet another NetEnt creation. Blood Suckers is an extremely popular slot with a 98% RTP rate.

It is a vampire-themed slot released in 2013. Expect spooky graphics and eerie sound effects from this dark game. Perfect for players who are on the hunt for something a little different.

Alongside freaky graphics, Blood Suckers provides free spins and mid-range jackpot wins. If you enjoy horror films or are looking for a jackpot slot with consistent returns, you’ll like this game.

Jokerizer — 98%

Yggdrasil is a software developer to watch, as proven by Jokerizer — a 98%-RTP slot.

This slot has five reels, three rows, and sought-after traditional slot symbols. You’ll find plenty of cherries, bells, and jokers here. Alongside these, the Jokerizer boasts a lively carnival theme:bright colours and a dynamic design.

Available at most UK casinos and websites, it’s best for players looking for frequent small wins, as big jackpots are rare.

White Rabbit Megaways — 97.72%

Launched in 2017 by Big Time Gaming, White Rabbit Megaways is a widely available slot machine — you’ll find this on most online gambling sites.

Players love this slot because it has the possibility for big payouts. This is due to special Megaways reel mechanics, which give you over 240,000 ways to win. Alongside these, White Rabbit Megaways offers expanding reels and free spin features.

As the name suggests, White Rabbit Megaways is based on Alice in Wonderland and features fitting graphics. If you like Megaways or slot games with fantasy themes, this might be one for you.

Big Bad Wolf — 97.35%

The Big Bad Wolf is a Quickspin slot that was released in 2013. This is a very in-demand title, and you’ll find it in most online casinos’ ‘Hot’ section.

So, why is Big Bad Wolf so popular? It provides mid-range wins and consistent payouts. This might not sound as interesting as some jackpot slots, but it’s great for low to medium-stakes players who want stable returns.

Big Bad Wolf offers swooping reels and free spins bonus rounds alongside frequent payouts. Pair these with the charming Three Little Pigs-inspired storyline and high RTP rate, and it’s easy to see why it’s a staple in Great Britain.

Reel Rush 2 — 97%

Reel Rush 2 was released in 2019, making the slot machine around five years old. This is another NetEnt game that players love for mid-ranged wins and varied bonus features (e.g., wilds and re-spins).

Another reason users return to this slot is for its fast-paced gameplay and traditional arcade game style.

Whether you used to play arcade games as a youngster or are partial to 80s aesthetics, Reel Rush can scratch that sentimental itch.

Rainbow Riches — 97%

Rainbow Riches (released in 2009 by Barcrest) is one of the older slots on this list. But don’t be fooled — it is still one of the best-paying slots in the UK.

You can find Rainbow Riches at online and physical UK casinos, and it’s nearly always in the ‘Hot’ slots sections. It has a classic Irish leprechaun theme and plenty of fitting graphics. Cute pots of gold, rainbows, and clovers. Aside from the joyful theme, Rainbow Riches provides mid-ranged consistent wins and creative bonus features. These include Pots of Gold and Wishing Well bonuses.

It’s ideal for players who want steady wins and the chance of rich jackpots.

The Dark Knight — 97%

IGT, also known as International Game Technology, released The Dark Knight in July 2012.

As you may have guessed, this slot is inspired by the Batman film of the same name. The slow borrows the same dark aesthetic and builds on the vibe with wilds, free spins, and a progressive jackpot.

The Dark Knight has a higher volatility than others on this list. It’s great for those who are looking for a high-stakes option, but not ideal if you want steady and small payouts.

Immortal Romance — 96.86%

Immortal Romance is one of Microgaming’s most famous creations. Released in 2011, you can find this title on nearly all British online casinos.

Unlike some of the traditional slots on this list, Immortal Romance has a darker and, at times, romantic theme. There’s also a tangible storyline and deep characters. Combine these details with four free spin modes and mid-range wins, and you can see why this is an all-time UK favourite.

Players who prefer slots with plots and narratives will enjoy this game.

Dead or Alive — 96.82%

Last on the best payout online slots in the UK list is Dead or Alive by NetEnt. This 2009 slot is a common sight in online and in-person casinos and is known for its big wins and high volatility.

If you’d prefer a low-volatility slot with small but consistent wins, this might not be the match for you.

In addition to potential big payouts, the Dead or Alive slot transports you to the Wild West with a riveting soundtrack and topical graphics. The NetEnt game also includes free spins, bonus rounds, and wild symbols that become sticky.

Slots Vs Other Casino Games

Unless on websites specialising in one casino game type, slots will usually be offered together with other game types, for instance, table games like roulette, blackjack, and poker. It’s useful to know how slots stand RTP rate-wise compared to table games, as it gives you a broader picture of your potential winnings on each game, therefore, helping you choose a title that matches your goals.

Like slots, table games also have the RTPs of 94% to 97% but rely heavily on the player’s skills rather than luck. It is in these games that knowledge and practice can increase your payouts.

Game	Variant/Title	2024 RTP
Online Slot	Ugga Bugga	99.07%
Online Slot	Book of 99	99%
Online Slot	Mega Joker	99%
Blackjack	Classic Blackjack	99.4%
Roulette	European Roulette	97.3%
Poker	Three Card Poker	96.63%

To Sum Up

It’s difficult to pinpoint the top lot of all time, as the games’ RTP percentages can change, and new slots are released frequently. Also, regulatory changes within the UKGC can impact slot machine payouts. Therefore, we won’t be taking the role of the ultimate judges — the choice is yours. You can use these 15 examples as a rough guide to where to start in finding your perfect match. Each has a high RTP, carefully considered features and a satisfying payout record. There’s always a new option to try.
