20 Best Relax Gaming Slots in the UK

This guide covers the best Relax Gaming slots in the UK for 2026, from a studio that is an established name in iGaming. A Malta-based online casino developer and content aggregator, Relax is continually growing its slots collection.

Fondly known for the Money Train series, Relax has delved into other areas, and its games feature Tumble mechanics, but more on that later. There are also high-RTP titles in its catalogue too, such as Book of 99.

This in-depth article provides the lowdown on the 20 best Relax Gaming slots to play in 2026. We’ve provided mini profiles of these games, and assessed what you should look out for when deciding what Relax Gaming slots to play.

Best Relax Gaming Slots in 2026

Relax Gaming titles are widely available at UK betting sites. Our table highlights the top Relax Gaming slots, noting the themes covered and the category they fall into.

Tumble Slots

Emerging as the most-searched series of Relax Gaming slots, Tumbles create chain reactions where winning symbols are removed from the grid, and new ones drop in their place.

Let’s take a closer look at some of the most popular Relax Gaming slot titles in the Tumble range.

 

Temple Tumble

Temple Tumble leans into the ancient temple theme expertly, taking players deep into the Cambodian jungle.

The reel layout is less conventional, starting with a 2-row setup, but players can unlock up to 7 rows on each reel, and this game adds Mystery Symbols. These transform into other symbols (except Wilds and Scatters), which can change the symbols on the grid.

Temple Tumble, at the time, received critical acclaim, and with its eye-catching visuals and features, this paved the way for the expansion of the Tumble series of games.

 

Temple Tumble Megaways

With its atmospheric jungle setting, Temple Tumble Megaways is played on a 6×6 grid, and there are 46,656 ways to win.

Although smaller compared to other Megaways titles, tumbling wins are incorporated into the title. Winning symbols explode and destroy surrounding blocks, making space for new symbols to drop in.

With cascades, they continue until no further wins can be created. Free Spins come into play when players destroy all stone blocks, and players can choose from 3 modifier styles, including multipliers which help boost payouts.

Like the original, it taps into the same stone block destruction system, but has a more sophisticated gaming mechanic as well as an Extra Spins feature to keep things interesting.

 

Templar Tumble

Tapping into the knights/medieval motif, Templar Tumble covers 6 reels and 6 rows, and unlike Temple Tumble, it offers more winways (117,649), and it has a lower RTP (94.00%).

Free Spins are activated when players destroy all blockers in the base game, triggering 6 free spins.

However, the Mystery Reveal is a cornerstone of the game. If a Wild falls in, a number of symbols are converted into Mystery symbols. These remain on the grid until the end of the round, and they can turn into Coin symbols, offering a return of 1,000x the bet, while in Free Spins, they can award an extra free spin.

 

Ancient Tumble

Covering a jungle theme, Ancient Tumble is a 6-reeled game, complete with 46,656 ways to win.

It fits into the Tumble range, and that is partly down to the Unbreakable Wilds. This can be triggered in normal base game spins, Enhanced Spins, Classic Free Spins, and Super Free Spins.

Unbreakable Wilds can be revealed after a Tumble, and while they can destroy any normal symbol directly below them after a cascade, they can’t remove other stone blocks or Unbreakable Wilds from the grid.

The other feature to note is the Coin Multiplier Symbols, which can appear in any spin. A destroyed coin multiplier can activate the corresponding coin multiplier and will multiply any coins present at the end of a round.

 

Cluster Tumble

Incorporating a bigger 8×8 grid, Cluster Tumble uses a Cluster pays mechanic, whereby wins are generated by accruing 4 or more matching symbols across the grid.

Although the Tumble mechanic is still evident as in other reel-based games in the Relax Gaming series, there are more blocks to remove in Cluster Tumble to create further winning opportunities.

More specifically, there are special features, such as Lightning Win, which is applied after a Cascade where all standard symbols can produce a win regardless of where they are on the board.

Meanwhile, the Free Spins feature plays out differently, as you get 5 free spins initially before receiving an extra 3 spins and a 3x multiplier. Treasure Tumble is also available to play at 7bet.

 

Money Train and Money Cart Slots

Money Train is among Relax Gaming’s best-known high-volatility slots, where players ride the rails in games focused around train heists, featuring special collector and modifier symbols.

The Money Cart games use a similar bonus-reel format, and we’ve explored the popular slots in this collection.

 

Money Train 3

A Wild West/train heist-themed game, Money Train 3 borrows the same steampunk influence as its predecessor Money Train 2, but it is a bit darker.

During the base game, the Respin feature can be randomly triggered where a random symbol on the board is selected, becomes sticky and awards another respin. Meanwhile, during Respins, multipliers up to 3x can land and can award an additional respin.

Collector symbols sum up all the visible values from other symbols on the reels, adding them to its own value.

Classified as very highly volatile, Money Train 3 stumps up a maximum win of 100,000x the bet, double that of Money Train 2.

 

Money Train 4

Money Train 4, the fourth entry in the series (Money Train 5 is now also available at 7bet), like Money Train 3, is also extremely volatile; however, it plays on a 6-reel grid.

Among the other differences are the special symbols. In Money Train 4, there is an Arms Dealer symbol transforming up to 4 bonus symbols into a feature symbol, while the Persistent Arms Dealer converts a bonus symbol into a feature symbol at the end of that spin and every spin after.

Money Train 4 also offers a higher win potential (150,000x your bet) compared to Money Train 3.

 

Money Cart 2

Adopting a mining theme, Money Cart 2 uses a 5-reel structure and a Bonus Reels mechanic.

The Bonus Reels mechanic requires players to land 3 bonus symbols to activate the Respins feature, with 3 spins awarded. Landing any additional bonus symbols resets the spins tally to 3.

For this game, Relax Gaming has added a Sniper symbol that doubles the value of up to 8 symbols, and the Necromancer can bring 7 symbols to life. Players can also fill a reel with symbols for an extra reel.

 

Money Cart 3

Leaning into post-apocalyptic vibes, Money Cart 3 introduces more special symbols into the mix compared to Money Cart 2.

For example, the Tommy Gun Payer reveals a coin value between 5 and 100, and selects a random value symbol to add the value to, multiplying it by 3 to 10x.

There is also a Persistent Shapeshifter which can turn into a different special symbol after every spin, including Tommy Gun Sniper or Tommy Gun Payer.

 

Money Cart 4

The latest entrant to the Money Cart series, Money Cart 4 is spread across 6 reels and 4 rows, with the potential to open 4 more rows.

Essentially, it mirrors the bonus version from Money Train 4, so you will come across characters such as the Arms Dealer.

However, compared to Money Cart 3, there are new symbols embedded, such as the Persistent Necromancer. This brings up to 7 symbols back to life at the end of a spin and every spin that follows. There is also an Upgrader feature where players can upgrade up to 3 special symbols into a Persistent version.

Money Cart 4 also carries a higher win ceiling (15,000x your bet) compared to its predecessor.

 

Relax Gaming Book Slots

Relax Gaming has provided its own sharp twist on the classic “Book of” format, notably the expanding symbol in free spins. We’ve fleshed out some details on the Relax Gaming slots covered in this category.

 

Book of 99

Encompassing an Ancient Greek theme, Book of 99 uses 5 reels and 3 rows, and is accompanied by 10 fixed paylines.

The Wild in this game is represented by the book symbol, substituting for all symbols except for the special expanding symbol in Free Spins.

On that note, landing 3 or more Wilds activates the Free Spins feature, offering 10 free spins. A special Expanding symbol is randomly selected and can pay out across all 10 lines according to the number of symbols landed.

The RTP for this game stands at 99%, and that is the confirmed figure displayed in the 7bet info panel.

 

Book of Power

Unlike Book of 99, Book of Power taps into the Ancient Egypt theme, stuffed with bonus features, including 2 free spins features.

One of the main differences compared to Book of 99 is the use of Power Free Spins. Landing 3 Book symbols, including a Power Book symbol, awards 10 Power Free Spins, while accruing 5 rewards 20 Power Free Spins.

Also, a Lucky Boost feature can be triggered at random in Book of Power.

 

Cluster and Megaways Relax Gaming Slots

Cluster and Megaways slots can provide a dynamic gaming experience, transforming potential winning opportunities with every spin. This segment takes a gander at some of the popular Cluster and Megaways slots in this range.

 

Kluster Krystals Megaclusters

Reflecting a distinct crystal theme, Kluster Krystals Megaclusters is the first Megaclusters slot created by Relax Gaming, where symbols split into smaller symbols.

Played on a 5×5 grid, this game contains three mini features that can be triggered after a sequence of 6 avalanches. For example, Krystal Boost upgrades all visible normal symbols by one stage.

Multipliers can land as 10x as a base multiplier and they can be upgraded when next to a winning cluster. Meanwhile, the Free Spins feature comes into play when the bonus symbol is upgraded fully, offering 7 free spins.

Upgrading a bonus symbol in Free Spins can retrigger free spins and award an additional 4 spins.

 

The Great Pigsby Megaways

A decadent 6×7 slot with a distinct 1920s theme paying homage to The Great Gatsby film, The Great Pigsby Megaways features pig characters, and it has a glamorous vibe. It adopts the Megaways format, as there are 117,649 different winways connected to the game.

The Wild Respin is one of the defining features of this slot. It awards up to 5 fully wild reels with multipliers which see their values multiply each other.

Also, any Wild symbol can activate the Free Spins round where 10 spins are awarded. Whenever a Scatter symbol lands, a further 2 free spins are awarded, and low-paying royals are removed from the grid. The maximum win cap available is 20,000x your bet.

 

Atlantis Crush

A vibrant underwater-themed slot, Atlantis Crush features a Clusters mechanic where players must land at least 4 matching symbols to engineer a win.

The Block symbols are one of the focal points of this title, and they can be activated by having a winning paying symbol by itself under itself or by the effect of another activated Block symbol.

There are also two Free Spins features, including Super Free Spins, where only the multiplier, bonus, and gem blocks can land on the blocks area.

 

Wildlife and Adventure Relax Gaming Slots

Relax Gaming’s slot portfolio is diverse, covering animal and adventure themes. Here’s our pick of the games along with some short profiles of key features and gameplay.

 

5 Wild Buffalo 2

Developed by 4ThePlayer and released through Relax Gaming, 5 Wild Buffalo 2 returns to the American plains, where herds of buffalo roam in a stampede-style setting.

The Golden Buffalo is the headline addition to the sequel. Stacked Golden Buffalo symbols carry a 10x multiplier, and the Golden Buffalo Shuffle feature moves these stacks across the reels to form buffalo wins. On any spin, diamonds can also land and raise the value of 1 of 5 Big Prizes, with a chance to spin the Fortune Wheel to win one of them.

Free Spins are triggered by landing 3 or more Scatter symbols. During the round, Wilds expand and carry multipliers, while Golden Buffalo stacks continue to move across the reels. The game is high volatility, with a maximum win of 7,500x your bet. Check the 7bet information panel for the reel layout and RTP.

 

Tiger Shrine

Encounter tigers in the jungle-themed slot Tiger Shrine. Spread across 6 reels and 4 rows, there are 4,096 ways to win.

The Reel Expansion mode is a central part of the game, as coins can increase the number of symbols on the reel on which it lands for the remainder of the bonus round. The reels can be expanded to increase winning ways up to 117,649.

During the base game, landing 3 or more bonus symbols triggers the bonus game, and players can pick from 1 of 3 different bonus game modes. 6 bonus symbols, for example, awards 25 free spins, and landing multiple bonus symbols offers up additional free spins.

 

Kraken’s Cove

Players can set sail in the pirate and sea monster-themed slot Kraken’s Cove. Set among a Caribbean cove, Kraken’s Cove utilises a Cluster pays mechanic, and wins can be created by landing 5+ symbols across the reels.

It has no fewer than 6 features, and the Ship Wild plays a key role. It is present in every spin, and once it reaches a hot spot, it can expand in size from a 2×2 to a 5×5 Wild, depending on the state of the Wild expansion.

The Ship Wild is also prevalent during Free Spins. 5 Free Spins are awarded when players land at least 3 Scatters, but the Free Spins round can upgrade the Ship Wild expansion and multiplier feature, making them persistent during the round.

 

Other Popular Relax Gaming Slots

The other Relax Gaming slots developed are a bit more quirky and light-hearted, and we’ve discussed their redeeming features here.

 

Net Gains

An overtly fishing-themed slot, Net Gains offers up to 4,096 different ways to win on the 6-reel grid.

The Coin Collection feature springs into life when players collect gold, silver, and bronze coins by landing collection chests or the persistent collection chest. Coin values can be upgraded by filling the coin meter, offering an extra free spin each time.

Stacked Wilds come to the fore, as do Mystery Symbols, which remain sticky during Free Spins. The Free Spins round is triggered by collecting at least 3 bonus symbols, and players can make a choice between 8 free spins in Coin Collection, 5 free spins in Sticky Mystery, or 7 free spins in Stacked Wild.

 

Bill & Coin

A quirky cartoon-themed slot, Bill & Coin features affluent characters donning top hats.

Using 6 reels and 4 rows, this game features a multiplier ladder where players start with 5 free spins and a 1x multiplier. After every win and between Free Spins, the multiplier can increase, and there is a maximum multiplier of 500x offered.

The other intriguing element of this game is the Sure Win Feature. Players start with free spins and a Sure Win of between 0.2x and 50x their bet. The accumulated win multiplier in Free Spins multiplies the Sure Win after normal wins have been added. The Super Bonus version of this game starts with 8 free spins. Bill & Coin 2 and Bill & Coin 3 are also available.

 

How to Choose the Best Relax Gaming Slot

Choosing the best Relax Gaming slots to play isn’t an easy task. However, being assiduous with your research helps. We’ve listed some key criteria that should be assessed before settling on a title.

 

Check the Theme

Relax Gaming’s gaming library incorporates a wide range of themes. This includes ancient temples, the Wild West, and wildlife titles.

For some, the theme is fundamental as it can go a long way to deciding whether it will sustain their interest in the long term. Although substance shouldn’t be sacrificed for style, pinpointing the theme is a good starting point.

 

Review Gaming Mechanics

Popular Relax Gaming slots come in many forms and guises, and they all offer something different. These might entail tumbles or Cascades, Megaways or Megaclusters engines, designed to enhance the overall gaming experience.

Whatever it is you are looking for, check the gaming mechanics to see which style you prefer, and review the paytable.

 

Check the RTP and Maximum Win

Remember, RTP levels can differ between operators, so don’t overlook this. Although a theoretical figure, it describes the average share of stakes returned over a very large number of spins and says nothing about a single session.

The RTP should be displayed in the 7bet gaming info panel, as will the maximum win offered. Some games may provide a larger win ceiling, which could sway some players, so read up on this.

 

Understand Volatility

Volatility is a critical component of any slot. For example, higher-volatility games carry greater risk. With a wider range of possible outcomes, returns are less frequent and long runs without a win are normal.

Relax Gaming slots vary in terms of volatility, but it is down to personal preference and player budgets. Each title should be checked individually to see whether it matches your preferences.
