Best Relax Gaming Online Casinos UK 2026: Top Sites for Money Train 2 and More
Relax Gaming has quietly become one of the most influential slot providers in the UK market. You may not see their logo on every billboard, but open any serious online casino and you’ll likely find Money Train 2, Temple Tumble, or Iron Bank taking up prime lobby space. The studio’s blend of high-volatility math, clean design, and genuinely inventive features has earned it a loyal following among players who want more than a fruit machine clone.
This guide is not another list of every casino that happens to host a Relax title. We focused on operators that combine a strong selection of Relax Gaming slots with fair bonuses, fast payouts, and UK licences. The result is a shortlist of real places to play in 2026, not a padded directory.
What Relax Gaming Brings to UK Online Casinos
Relax Gaming started in 2010 in Malta and spent its early years as a B2B platform provider. The pivot to proprietary slots came later, and it changed the company’s trajectory. Instead of flooding the market with dozens of average games, Relax focused on a smaller catalogue of titles that push volatility and feature design.
Money Train 2 is the obvious case study. Released in 2020, it remains one of the most played slots in UK casinos because of the Money Cart bonus round, a sequence that can deliver multipliers well beyond what most slots allow. The base game RTP is 96.4%, but the bonus buy option changes the maths. More on that later.
Then there’s Temple Tumble, a cascading grid slot that feels more like a puzzle than a one-armed bandit. Iron Bank, with its heist theme and sticky wilds, is another title that gets heavy rotation. The common thread is that Relax slots rarely feel like reskins of the same engine. That matters when you’re trying to find a game that holds attention beyond the first ten spins.
How We Rank the Best Relax Gaming Casinos
We used four criteria. First, the breadth of the Relax Gaming catalogue. A casino that offers only Money Train 2 and one other title is not a serious destination. Second, the bonus terms, specifically wagering requirements and whether free spins come with strings attached. Third, payment speed and the availability of UK-friendly methods. Fourth, the overall user experience, from search filters to mobile performance.

We did not give extra points for a flashy welcome offer that requires a 45x wagering marathon. We looked for operators that treat bonuses as a teaser, not a trap. The UK Gambling Commission has cracked down on misleading promotions, but some casinos still push borderline offers. We ignored those.
The Best Relax Gaming Casinos UK 2026 Compared
The table below summarises the operators that made the cut. Bonus details change frequently, so we list the type of offer, not specific amounts. Always check the current terms on the casino’s site before depositing.

This is not an exhaustive list of every UK casino with Relax Gaming slots. It is a curated selection where the operator’s overall quality matches the strength of the provider’s games. If a casino appears, it means we would actually play there with our own money.
Detailed Look at the Top Relax Gaming Casinos
Each of these operators has a distinct personality. The common denominator is a reliable Relax Gaming integration and a licence from the UK Gambling Commission.
PlayOJO
PlayOJO built its reputation on a simple promise: no wagering requirements on bonuses. That matters more at a Relax Gaming casino than you might think. Many slots, including Money Train 2, have bonus buy features that can wipe out a bonus balance quickly if wagering is attached. At PlayOJO, your winnings from free spins are yours to withdraw, minus the usual identity checks. The Relax selection is deep, and the OJOplus cashback programme returns a small percentage of every bet, win or lose. It is not a “VIP” scheme in the traditional sense; there are no hosts or limousines. But the cashback is real, and that’s more than most loyalty programmes deliver.
Casumo
Casumo’s gamified adventure format is either charming or irritating, depending on your taste. The casino itself is solid: a large slot library, responsive customer support, and regular promotions tied to new Relax releases. The welcome offer is a deposit match, but the real draw is the ongoing rewards that accumulate as you play. Do not expect to get rich from the loyalty points. The value is moderate, and the wagering on bonus funds is standard for the UK market.
LeoVegas
LeoVegas remains one of the best mobile-first casinos in the UK. If you prefer playing Relax Gaming slots on a phone, this is a safe choice. The app is fast, the search function finds Money Train 2 in seconds, and the game pages load without stutter. The welcome package includes free spins on selected slots, sometimes including new Relax titles. Withdrawal times can stretch to five days for some methods, which is not the quickest on this list. Still, the overall polish is hard to beat.
Mr Green
Mr Green has been around long enough to remember when Relax Gaming was a niche provider. The casino now features a strong selection of Relax slots, including older titles that some newer casinos ignore. Mr Green’s focus on responsible gambling is genuine. You can set loss limits, reality checks, and self-exclusion tools without jumping through hoops. The bonus terms are transparent, even if the amounts are not the most generous. That trade-off is worth it for peace of mind.
Rizk
Rizk’s Wheel of Rizk is a clever retention tool. You earn points for playing and then spin a wheel for prizes. The prizes can include free spins, cash, or even deposit bonuses. The catch? The wheel spins are limited, and the big prizes are rare. But the process is fun, and it adds a layer of engagement that suits Relax’s high-energy slots. Rizk also has fast withdrawals and a clean interface. It is not the loudest casino in the UK, but it is one of the most straightforward.
Duelz
Duelz is the youngest brand in this group, and it leans into social features. You can challenge other players in duels while spinning Relax slots. This sounds like a gimmick, but it is surprisingly engaging if you enjoy a competitive edge. The casino’s bonus offers are decent, and the Relax catalogue is well represented. Duelz also runs regular tournaments on specific games, which gives you a reason to try titles you might otherwise skip.
Videoslots
Videoslots is the slot encyclopedia of the online casino world. It hosts thousands of games, including every Relax Gaming title we could name. The search filters are excellent, and the Battle of Slots feature lets you compete against other players on selected slots, including Relax games. The welcome bonus is standard, but the real value is in the daily free spins and tournament prizes. Withdrawal speeds are good, and the UK licence is solid. If you want maximum choice, Videoslots is hard to fault.
Unibet
Unibet is a mainstream operator with a massive sportsbook and a casino that quietly delivers. The Relax Gaming selection is not the largest, but it includes the headline titles. The welcome bonus is straightforward, and the payment system is reliable. Unibet’s customer support is better than average, and the app works well for both sports and casino. If you already have a Unibet account, adding Relax slots to your rotation is a no-brainer.
888casino
888casino is one of the oldest online casino brands in the UK. Its proprietary platform means the game loading screens feel a little different from white-label casinos, but the Relax Gaming slots are present and correct. The welcome bonus is modest, but the casino’s longevity and financial stability are reassuring. Withdrawal processing is reliable, and the app has improved significantly in recent years. It lacks the flair of some newer casinos, but it does the job without drama.
William Hill
William Hill is another legacy operator that has added Relax Gaming titles without making a fuss. The casino’s integration is clean, and the slots run smoothly on both desktop and mobile. The bonus offers are typical of a large operator: solid but not spectacular, with moderate wagering. William Hill’s main advantage is trust. It has been regulated in the UK for decades, and its customer service is accessible. If you prefer a familiar name over a flashy newcomer, this is a safe option.
Relax Gaming Slots You Should Play in 2026
Relax Gaming’s catalogue is not vast, but it is deep. The studio releases fewer than ten slots per year, and each one gets a thorough testing period before launch. Below are the titles that matter most in UK casinos right now.
Money Train 2
Still the flagship. The base game is a 5×4 reel with 40 paylines, but nobody plays it for the base game. The Money Cart bonus is where the magic happens. Persistent multipliers, collector symbols, and re-spins can push wins into five-figure multiples in rare cases. The RTP is 96.4%, but the bonus buy option (where available) lets you enter the feature directly at a cost. In the UK, bonus buy is restricted at some casinos, so check before you deposit. The volatility is extreme, which means long dry spells are guaranteed. Do not mistake a few losing sessions for a broken game.
Temple Tumble
A cascading grid slot with a 6×6 layout and 46,656 ways to win. The cascades can trigger multiple consecutive wins, and the bonus round adds multipliers that increase with each cascade. It is less brutal than Money Train 2 but still high variance. The ancient temple theme is well executed, and the soundtrack is surprisingly calming for a slot that can empty your balance in ten minutes.
Iron Bank
Heist-themed with a 6×4 grid and 4,096 ways. The standout feature is the free spins round where sticky wilds build multipliers. The game also includes a bonus buy option in some jurisdictions. Iron Bank has a 96.2% RTP and a reputation for delivering big wins during the feature, though the base game can feel sparse. The art style is sharp, with a clear Debt of the Dead vibe.
Hellcatraz
A pixel-art slot with a 1960s prison theme. It uses a 6×6 grid with up to 46,656 ways. The free spins round can produce massive multipliers, and the maximum win potential is over 10,000x. The RTP is 96.4%. Hellcatraz is not for the faint-hearted; the bonus round is rare and the base game hits are small. But when it hits, it hits hard.
Snake Arena
A 5×5 grid with 25 paylines and a medieval snake theme. The free spins feature includes a wild snake that grows and moves across the reels. The RTP is 96.25%, and the volatility is high but slightly lower than Money Train 2. Snake Arena has a cult following because of the satisfying moment when the snake eats a symbol and expands.
Other notable Relax titles include Wild Chapo, Top Dawgs, Money Cart 2, and Marching Legions. Each has its own mechanic, but all share the signature Relax approach: high variance, high reward ceiling, and clean presentation.
Bonuses and Promotions at Relax Gaming Casinos
The UK Gambling Commission banned auto-play and restricted bonus buy features in 2021. That changed how casinos promote Relax Gaming slots. You will rarely see a bonus specifically tied to Money Train 2 with a bonus buy attached. Instead, operators offer general deposit matches or free spins that can be used on selected slots.
Free spins are often the most common promotion for Relax titles. A casino may give you 20 spins on Temple Tumble when you deposit £10. The catches vary. Some free spins have a 1x wagering requirement, which is effectively zero. Others attach a 35x wagering requirement to any winnings, which makes them nearly worthless. Always read the terms. If the casino does not clearly state the wagering before you opt in, walk away.
No deposit bonuses are rare in the UK market, and that includes Relax Gaming casinos. The UKGC discourages offers that require no financial commitment because they attract bonus abuse. A handful of operators still offer small no deposit free spins to new players, but the amounts are tiny and the wagering is usually high. Treat any “free” bonus as a trial, not a gift. Casinos are not charities.
Payment Methods and Withdrawal Speeds
UK players have access to a wide range of payment methods at Relax Gaming casinos. Debit cards, PayPal, Skrill, Neteller, Trustly, and Paysafecard are standard. The UKGC banned credit cards for gambling in 2020, so you will not see that option. E-wallets provide the fastest withdrawals, often within 24 hours. Debit card withdrawals take one to three banking days, while bank transfers can stretch to five.
Some casinos advertise “fast withdrawals” but then add a 48-hour pending period. That is not fast. We looked for operators that process withdrawals without artificial delays. PlayOJO, Rizk, and Videoslots stand out for their quick turnaround. LeoVegas can be slower, especially on weekends. The lesson: do not assume speed based on marketing claims.
Minimum deposits are generally £10, but some casinos allow £5 via certain methods. The table above uses £10 as the standard minimum because that is the most common threshold. If you want to play with smaller amounts, check the cashier page for the actual minimum for your chosen payment method.
Mobile Play and Apps
Every casino on this list has a mobile-optimised website, and most offer native apps for iOS and Android. Relax Gaming slots are built on HTML5, which means they run smoothly in a mobile browser without a dedicated app. The difference comes down to app performance and navigation. LeoVegas has the best overall mobile experience, with a fast app and intuitive search. Casumo and Duelz also perform well on smaller screens.
One thing to note: not all Relax slots support portrait mode. Money Train 2 and Temple Tumble are best in landscape, which is fine on a tablet but awkward on a phone unless you rotate. The casinos do not control this; it is the slot design. If you plan to play on a phone, test the game in both orientations before committing real money.

New Relax Gaming Casinos to Watch
The UK market is saturated, but new casinos launch every month. Some of them partner with Relax Gaming from day one because the provider’s reputation attracts players. We track new operators that offer Relax slots and have obtained a UKGC licence. In 2025 and into 2026, several new brands have appeared, but most are white-label casinos with the same backend and a different logo. That is not necessarily a negative; white-label casinos can be reliable if the parent company is reputable. However, do not fall for a new casino just because it advertises “Money Train 2 welcome bonus”. The bonus terms are often worse than those at established operators.
If a new casino catches your eye, verify its UKGC licence number on the official register before depositing. The licence number should be displayed in the casino footer, linked to the Commission’s website. If it is missing or not clickable, avoid it. No amount of Relax Gaming slots makes an unlicensed casino worth the risk.
Responsible Gambling and Safer Play
Relax Gaming slots are high volatility by design. They can produce long losing streaks, and the bonus buy feature (where available) accelerates losses. That makes responsible gambling tools even more important at these casinos. All UKGC-licensed operators must provide deposit limits, reality checks, time-outs, and self-exclusion. The casinos on our list do this properly. Mr Green and PlayOJO are particularly strong in this area.
Set a budget before you open Money Train 2. Decide how much you are willing to lose, and stop when you hit that number. The game will not tell you to stop; it will just show another spin button. If you feel that gambling is no longer a choice, use the self-exclusion tools or contact GamCare or BeGambleAware. The UK National Gambling Helpline is 0808 8020 133. No slot, no matter how well designed, is worth your financial stability.
Players often ask the same set of questions about Relax Gaming casinos. Here are the most common ones, answered without the usual marketing fluff.
Can I play Relax Gaming slots for free in the UK?
Yes. Most UK casinos offer a demo mode for Relax Gaming slots, including Money Train 2 and Temple Tumble. You do not need to deposit, and the demo uses virtual credits. This is the best way to learn the mechanics without risking real money. Note that some bonus buy features are disabled in demo mode.
Are Relax Gaming casinos licensed and safe in the UK?
All casinos listed in this guide hold a UK Gambling Commission licence. That means they must follow strict rules on player funds, fair games, and responsible gambling. Relax Gaming itself is licensed as a game supplier in multiple jurisdictions. Always verify the casino’s licence before playing, even if it appears on a trusted site.
What is the highest RTP Relax Gaming slot?
Money Cart 2 has an RTP of 98% in its base game, but the number drops if you use the bonus buy feature. Among standard slots without bonus buy, Money Train 2 and Hellcatraz sit at 96.4%. Temple Tumble is 96.25%, and Iron Bank is 96.2%. RTP is a long-term average, not a guarantee for any single session.
Do UK casinos offer no deposit bonuses for Relax Gaming slots?
Rarely. The UK Gambling Commission’s rules make no deposit bonuses unattractive for operators because they attract bonus hunters. A few casinos occasionally offer 5–10 free spins on registration, but the wagering requirements are usually high. Treat any no deposit offer as a trial, not a path to profit.

Can I play Money Train 2 at UK online casinos?
Yes, Money Train 2 is available at nearly all UK casinos that carry Relax Gaming slots. The game’s bonus buy feature may be disabled or renamed depending on the operator and regulatory changes. Check the game rules after loading to see if the feature is active. The base game remains identical across casinos.
This guide is a snapshot of the UK market in early 2026. Bonus terms, game availability, and casino licences can change overnight. Always verify the current offer on the operator’s site and gamble responsibly.
