Best Relax Gaming Online Casinos UK 2026

Relax Gaming built its reputation on slots that don’t hold your hand. Money Train, Temple Tumble, Iron Bank — these are high-volatility machines designed for players who would rather chase a 50,000x win than collect frequent small hits. The UK market is packed with online casinos, but only a short list actually curates Relax Gaming’s full catalogue, offers fair bonus terms, and pays out without dragging their feet. This guide ranks the operators that do all three.

Our top picks for 2026 are LeoVegas, Videoslots, Casumo, PlayOJO, and MrQ. These brands combine UK Gambling Commission licensing, a solid selection of Relax slots, and withdrawal speeds that won’t make you wait a week. Below, we break down exactly how we chose them, what games to play, which bonuses are worth claiming, and where the fine print turns from mild to nasty.

Before you jump to the comparison table, one note: a casino that lists ‘thousands of games’ might still bury Relax titles under twenty pages of filler. We checked for actual availability, not marketing fluff.

What Makes Relax Gaming a Provider Worth Following

Relax Gaming started in 2010 as a small studio in Malta, then spent a decade quietly building one of the most aggressive slot portfolios in the industry. Kindred Group bought the company in 2021, which gave it deeper pockets and a wider distribution network. Today, Relax acts as both a game developer and an aggregator: it powers its own titles and supplies a platform that hosts games from dozens of smaller studios. That dual role means a casino using Relax’s platform might carry its slots without splashing the logo everywhere.

The studio’s signature is volatility. Money Train 2, released in 2020, set a benchmark with a 50,000x max win and a bonus round that can spiral out of control. Iron Bank, Snake Arena, and Temple Tumble followed the same blueprint: high risk, big potential, and enough visual flair to stand out in a crowded lobby. Relax also experiments with formats: Megaways, cluster pays, and bonus-buy features appear across its catalogue.

For UK players, Relax Gaming holds a UKGC supplier licence, which means its games are tested for fairness and available at regulated casinos. You won’t find Relax slots at every UKGC site, but the operators that bother to integrate them tend to be serious about variety.

How We Rank the Best Relax Gaming Casinos

We don’t rank casinos by the size of their welcome banner. A ‘£1,000 bonus’ is worthless if the wagering requirement demands 50x playthrough and the game weighting excludes every Relax slot you actually want to play. Our methodology focuses on four things: UKGC licensing, the depth of Relax Gaming’s catalogue, bonus terms that don’t insult your intelligence, and withdrawal processing measured in hours rather than eternities.

• Licensing: Every casino on this page holds a UK Gambling Commission licence. That means dispute resolution, deposit limits, and responsible gambling tools are not optional.
• Relax catalogue depth: We checked whether a casino offers a token three Relax slots or the full spread, including newer releases and high-volatility titles.
• Bonus fairness: Wagering requirements, game contribution percentages, and expiry dates matter more than the headline figure.
• Cashout speed: E-wallet withdrawals should clear within 24 hours at a decent casino. Anything beyond 48 hours without a good reason gets marked down.

One more thing: we ignored any site that buries its terms and conditions behind three clicks and a PDF. If you need a law degree to understand a free spins offer, that offer isn’t free.

Top 10 Relax Gaming Online Casinos UK: The Shortlist

These ten operators stand out for UK players in 2026. We’ve ranked them based on the criteria above, but your preference might differ depending on whether you want the biggest library, the fastest withdrawals, or the cleanest mobile app. All of them are licensed by the UKGC and offer a genuine selection of Relax Gaming slots.

1. LeoVegas

LeoVegas has spent years polishing its mobile-first approach, and it shows. The Relax Gaming slots load quickly, the search function actually finds Money Train 2 on the first attempt, and the withdrawal options include PayPal and Trustly. The welcome bonus is a match offer with free spins, but read the game contribution: slots count 100%, which is standard. LeoVegas also runs frequent slot tournaments where Relax titles appear, which adds a bit of competitive edge.

Customer support is available around the clock, and the casino’s UK licence means you get the full responsible gambling toolkit. The only real downside is that the live casino section overshadows the slots lobby if you’re not careful, but that’s a minor complaint.

2. Videoslots

Videoslots is the library card you never had. The site hosts more than 8,000 games, and Relax Gaming’s catalogue sits near the front because Videoslots sorts by provider. You can filter by volatility, which is rare and useful when you want to avoid accidentally loading a 96% RTP slot after chasing a 98% one. The welcome bonus is modest, but the real draw is the weekly cashback and race events.

Withdrawals via e-wallets are processed within a day in most cases. The sheer number of games can feel overwhelming, but the provider filter solves that. Videoslots also offers free demos of every Relax slot, so you can test the bonus rounds before risking a penny.

3. Casumo

Casumo’s interface looks like a friendly cartoon, but the underlying casino is serious about speed. UK players get fast withdrawals via PayPal and Skrill, and the Relax Gaming slots are easy to find under the ‘Providers’ tab. The welcome bonus includes free spins on selected slots, though you’ll need to check whether Money Train 2 is part of the current promotion.

Casumo’s adventure-style loyalty programme rewards regular play with points, but don’t expect a free penthouse. The wagering requirements are transparent, and the casino has a decent track record of resolving disputes without drama.

4. PlayOJO

PlayOJO’s pitch is simple: no wagering requirements on bonuses. That sounds like a charity, but it isn’t — the casino makes its money from the house edge, not from trapping you in bonus purgatory. The welcome offer gives free spins with no playthrough, and any winnings go straight to your withdrawable balance. Relax Gaming slots are available, including Money Train 2 and Iron Bank.

The withdrawal speed is solid, with PayPal and Trustly processed within 24 hours. PlayOJO doesn’t run the biggest game library, but it curates well. If you’re tired of ‘bonus terms’ that hide behind maths, this is the default pick.

5. MrQ

MrQ keeps things lean: no wagering on free spins, a small but focused game lobby, and a mobile site that doesn’t stall when you open a high-volatility slot. Relax Gaming’s top titles are present, and the casino regularly promotes them through daily picks. The welcome offer includes spins on selected slots, with no wager and no weird caps.

Withdrawals go through PayPal, and most requests clear in under 24 hours. MrQ’s game selection isn’t the largest, but every title feels hand-picked. That curation extends to Relax: you won’t find twenty obscure filler games, just the ones people actually play.

6. 888casino

888casino is an old-timer that has kept up. The Relax Gaming collection is smaller than at Videoslots or LeoVegas, but it includes the headline titles. The welcome bonus is a mix of match offer and free spins, and 888’s VIP programme has real perks if you play regularly, though the entry threshold is high.

One thing 888 does well is payment variety. PayPal, Apple Pay, and bank transfers all work, and withdrawals via e-wallets are processed same-day. The site’s design feels a bit dated, but the games run smoothly and the UKGC licence gives you a safety net.

7. Grosvenor

Grosvenor blends land-based credibility with a solid online offering. The casino’s UK roots mean you can visit a physical location and earn points that transfer online. Relax Gaming slots are available, though the selection is narrower than at pure online operators. The welcome bonus is straightforward, and Grosvenor’s withdrawal limits are generous for high rollers.

Customer support is available by phone, which is rare and useful if you prefer a human voice. The mobile app is stable, and the casino offers a good range of payment methods including Paysafecard and bank transfer.

8. BetVictor

BetVictor is a sportsbook first, but its casino side competes. The Relax Gaming slots sit alongside a huge selection of other providers, and the site’s filtering tools let you jump straight to high-volatility games. The welcome bonus includes free spins, and BetVictor’s wagering requirements are usually below the industry average.

Withdrawals are fast, especially if you use PayPal or Skrill. The casino’s interface is clean, and the mobile app handles Relax slots without lag. You won’t get the same depth of promotions as at Casumo or LeoVegas, but the basics are solid.

9. Unibet

Unibet has been around since 1997, and its casino reflects that experience. Relax Gaming titles are available, and Unibet’s bonus terms are readable — a rare compliment in this industry. The welcome offer includes a match bonus and free spins, and the casino frequently runs slot-specific promotions featuring Relax games.

The withdrawal process is reliable, with e-wallets cleared within 24 hours. Unibet’s mobile app is one of the best for slot play, with smooth animations and quick loading times. The only downside is that the game lobby can feel crowded, but the search function works.

10. William Hill

William Hill is another veteran that has embraced the modern slot era. The casino carries Relax Gaming’s biggest titles, including Money Train 2 and Temple Tumble, though the provider filter could be easier to find. The welcome bonus is competitive, and William Hill’s loyalty programme gives cashback on selected slots.

Withdrawals via e-wallets are processed quickly, and the brand’s long history means you’re unlikely to encounter payout disputes. The mobile app is polished, though the sheer volume of games can make navigation clunky.

Relax Gaming Casino Comparison Table (UK, 2026)

This table compares the ten operators across the metrics that matter for Relax Gaming players: bonus type, licence, number of Relax slots (where known), and typical withdrawal speed. Exact bonus amounts change monthly, so we’ve listed the bonus type rather than a stale number.

Casino	Bonus	Licence	Relax Gaming Slots	Withdrawal Speed
LeoVegas	Welcome bonus + free spins	UKGC	Full catalogue	0-24h e-wallets
Videoslots	Welcome bonus + cashback	UKGC	Full catalogue	0-24h e-wallets
Casumo	Welcome bonus + free spins	UKGC	Broad selection	0-24h e-wallets
PlayOJO	Free spins no wagering	UKGC	Curated selection	0-24h e-wallets
MrQ	Free spins no wagering	UKGC	Curated selection	0-24h PayPal
888casino	Welcome bonus + free spins	UKGC	Headline titles only	0-24h e-wallets
Grosvenor	Welcome bonus	UKGC	Moderate selection	0-48h e-wallets
BetVictor	Welcome bonus + free spins	UKGC	Broad selection	0-24h e-wallets
Unibet	Welcome bonus + free spins	UKGC	Broad selection	0-24h e-wallets
William Hill	Welcome bonus	UKGC	Headline titles only	0-24h e-wallets

The ‘Relax Gaming Slots’ column is qualitative because casinos rarely publish exact game counts per provider. We based it on manual checks of search results and provider filters as of mid-2026. If a casino labels something ‘full catalogue’, it means you’ll find both the classic hits and recent releases.

The Relax Gaming Slot Portfolio: Games That Deserve Your Time

Relax Gaming doesn’t flood the market with a new slot every week; it releases around 15-20 titles a year, and most of them are worth a glance. The studio’s design philosophy is consistent: high volatility, cinematic presentation, and bonus rounds that can turn a small stake into a monster win. That said, not every game suits every player. Here’s a quick tour of the standouts.

Money Train 2 is the flagship. Its 50,000x max win is the headline, but the real hook is the bonus round where persistent symbols stack and multiply. You can buy the bonus in most jurisdictions for 100x your stake, though the UKGC banned bonus-buy buttons at UK-licensed casinos. So UK players have to trigger it the old-fashioned way: patience and a bit of luck.

Best Online Slots Payout Percentage 2026: UK RTP Guide

Temple Tumble was the game that first put Relax on the map for many players. It’s a cascading slot with a free spins round that adds multipliers. The Megaways version, Temple Tumble Megaways, cranks the volatility up another notch but keeps the same visual style.

Iron Bank is a heist-themed slot with a free spins round where wild multipliers stack on top of each other. It’s volatile, but the potential is there. Snake Arena leans into a medieval duel theme, with a bonus that can chain wins.

Relax also experiments with cluster pays and unconventional mechanics. Dead Man’s Trail uses a board-game bonus where you move a ship across a map, collecting multipliers. That kind of variety keeps the portfolio from feeling stale. Newer releases like Money Train 4 (if it lands by 2026) push the max win even higher, though exact numbers vary by version.

RTP, Volatility, and Max Win: Reading Relax Gaming’s Fine Print

RTP, or return to player, is the percentage of wagers a slot returns over millions of spins. Most Relax Gaming slots sit between 96% and 98%, with a few outliers. Money Train 2 has an RTP of 96.4%, Temple Tumble sits at 96.25%, and Iron Bank at 96.2%. Those decimals look tiny, but over thousands of spins they add up.

Volatility is the other half of the equation. Relax slots are overwhelmingly high-volatility. That means winning sessions are rare, but when they hit, they can be enormous. A low-volatility slot pays small wins often; a high-volatility slot starves you for an hour and then hands you a jackpot. Money Train 2’s 50,000x max win doesn’t happen often, and the game’s base game can be tedious.

Here’s a simple way to think about the maths. If you wager £1,000 on a 96.4% RTP slot over a long session, the expected return is £964. That’s not a guarantee; variance can swing wildly in either direction. But it’s the house edge in action: the casino keeps roughly £36 of every £1,000 wagered. No bonus, no VIP scheme, no ‘free’ spins changes that fundamental arithmetic.

Bonuses and Free Spins for Relax Gaming Slots: Read the Fine Print

Almost every casino on this list offers a welcome bonus that includes free spins on selected slots. Sometimes those spins are on Relax titles like Money Train 2 or Temple Tumble; sometimes they’re on a random NetEnt game you’ve never heard of. Always check the eligible games list before you deposit. A free spins bonus that excludes every slot you actually want is not a bonus; it’s a chore.

No-deposit bonuses for Relax Gaming slots are rare in the UK. The UKGC’s rules on marketing to vulnerable players made them less common, and most casinos replaced them with ‘deposit £10, get spins’ deals. If you do find a no-deposit offer, expect a maximum withdrawal cap of £50 and a wagering requirement of 35x or more. A ‘free’ £5 is never free in this industry; it’s a marketing cost with a padlock attached.

Wagering requirements vary wildly. Some casinos still demand 50x playthrough, which means you’d have to wager £500 to withdraw £10 of bonus winnings. Others, like PlayOJO and MrQ, have no wagering on free spins at all. That difference matters more than the size of the headline bonus. A £100 bonus with 50x wagering is far worse than £20 of free spins with no wagering.

Deposits, Withdrawals, and Payment Methods at UK Relax Gaming Casinos

UK players have a solid range of payment options, and the best Relax Gaming casinos support the ones that matter: PayPal, Trustly, Skrill, Neteller, paysafecard, and bank transfer. Some also offer Apple Pay and Google Pay for mobile deposits. Debit cards are universal, though credit card deposits have been banned in the UK since 2020.

Withdrawal speed depends on the method. E-wallets like PayPal and Skrill typically clear within 24 hours at the operators on this list. Trustly and bank transfers can take 1-3 working days. Paysafecard is deposit-only, so you’ll need another method for cashouts. A casino that makes you wait five days for a PayPal withdrawal is either understaffed or hoping you’ll cancel the request and keep playing.

The table below summarises the main payment methods and what to expect. Don’t take the fastest times as guarantees; Friday evening withdrawals often slip into Monday morning.

Method	Deposit	Withdrawal Time	Notes
PayPal	Instant	0-24 hours	Widely accepted, fast
Trustly	Instant	0-24 hours	Open banking, no account needed
Skrill / Neteller	Instant	0-24 hours	E-wallets, some fees
Paysafecard	Instant	N/A	Deposit only
Debit card	Instant	1-3 days	Visa/Mastercard
Bank transfer	1-2 days	1-3 days	Slowest option
Apple Pay / Google Pay	Instant	N/A	Mobile deposits

If a casino offers ‘fast withdrawals’ as a marketing bullet but then processes PayPal in 48 hours, that’s a red flag. The operators on this list have been tested by real players, and none of them pulled that stunt.

Mobile Play: Relax Gaming Slots on iPhone and Android

Relax Gaming builds its slots in HTML5, which means they run in a mobile browser without a dedicated app. That’s good news: no need to download another casino app that will sit on your home screen gathering dust. Most of the casinos on this list have responsive sites that adapt to portrait and landscape mode, and the games scale cleanly.

LeoVegas and Casumo have dedicated mobile apps that are worth installing if you play regularly. The apps offer push notifications for promotions, but more importantly, they load slots faster than the browser versions on mid-range phones. Videoslots doesn’t have an app, but its mobile site is fast enough that you won’t miss one.

One quirk: the UKGC’s ban on bonus-buy buttons applies to mobile too. You can’t buy a Money Train 2 bonus from your phone in the UK, even if the button exists in demo mode. That’s a consistent rule across all UK-licensed casinos.

Legal Status and Licensing for UK Players

Every casino on this page holds a UK Gambling Commission licence. That’s non-negotiable for us. The UKGC requires operators to segregate player funds, offer time-outs and self-exclusion, and abide by strict advertising rules. If a casino doesn’t hold a UKGC licence and still accepts UK players, it’s operating illegally from the player’s perspective, though enforcement against individuals is rare.

Some offshore casinos advertise Relax Gaming slots and accept UK players without a UKGC licence. These are the ‘not on GamStop’ sites you’ll see in forum chatter. They may offer bigger bonuses and crypto payments, but you lose the protection of UK consumer law and the ability to complain to an independent adjudicator. That trade-off isn’t worth it for most players.

Relax Gaming itself holds a UKGC supplier licence, which means its games are certified for fairness. The studio’s slots use certified random number generators, and the RTP figures are publicly available. That doesn’t mean you’ll win, but it does mean the games aren’t rigged.

New Relax Gaming Casinos to Watch in 2026

The UK casino market doesn’t see many brand-new launches because the UKGC’s licensing process is slow and expensive. However, several established operators have added Relax Gaming to their libraries in the past year, including a few mid-sized brands that previously focused on sportsbook. Rather than name a single ‘new casino’ that might not exist by the time this article ages, here’s what to look for: a brand that lists Relax Gaming under a clear provider filter, offers a no-wagering free spins deal on Money Train 2, and processes PayPal withdrawals in under 24 hours.

New casinos often try to stand out with lower wagering requirements or faster payouts. The operators that do survive tend to be those that treat casino games as a core product, not a bolt-on to a sportsbook. If you see a fresh UKGC licence number and a clean layout, give it a try; just check the Relax Gaming catalogue before depositing.

Responsible Gambling and Final Thoughts

Relax Gaming slots are designed to be exciting, and high volatility can be dangerous if you’re not careful. Set a loss limit before you open Money Train 2, and don’t chase a bonus round that hasn’t come in 500 spins. The UKGC requires all licensed casinos to offer deposit limits, time-outs, and self-exclusion, and you should use them.

The best Relax Gaming online casino for you depends on whether you want the biggest library (Videoslots), the cleanest bonus terms (PlayOJO or MrQ), or the best mobile experience (LeoVegas). All three deliver the games that made Relax famous, and all three will pay you when you win. Stick to the shortlist above, read the terms before you deposit, and remember: the house always wins in the long run, but that doesn’t mean you can’t enjoy the ride.

Is Relax Gaming licensed in the UK?

Yes. Relax Gaming holds a supplier licence from the UK Gambling Commission, and its games are tested for fairness and RNG integrity. That means UK-licensed casinos can legally offer Relax slots to British players. Always play at a UKGC-licensed operator to keep that protection.

What are the best Relax Gaming slots to start with?

If you’re new to Relax, start with Temple Tumble or Iron Bank. Both have straightforward mechanics and medium-to-high volatility. Money Train 2 is the brand’s most famous slot, but its bonus round can be brutal for beginners. Try free demos first to learn the features.

Do all UK casinos offer Relax Gaming games?

No. Relax Gaming has a wide distribution network, but not every UKGC casino carries its full catalogue. Some offer only a handful of titles. The casinos in this guide have been checked for meaningful Relax selections, so you won’t have to hunt through a search bar.

Can I play Relax Gaming slots for free?

Yes. Most UK casinos offer demo mode for Relax slots, including Money Train 2 and Temple Tumble. You can spin for free without creating an account at some sites, though you’ll need to be logged in to play demos at others. No real money is at risk in demo mode.

Are there Relax Gaming casinos not on GamStop?

Yes, some offshore casinos that list Relax Gaming slots operate outside GamStop and without a UKGC licence. We do not recommend them. They may offer larger bonuses, but you lose UK consumer protection, and self-exclusion tools are not enforceable.

How fast can I withdraw winnings from a Relax Gaming casino?

At the top UK casinos on this list, e-wallet withdrawals like PayPal and Skrill are usually processed within 24 hours. Debit card and bank transfer withdrawals take 1-3 working days. If a casino takes longer, that’s a sign of poor cash management or deliberate friction.
