Best Relax Gaming Online Casinos UK 2026
Relax Gaming didn’t just wander into the slots scene—it bulldozed its way to prominence with a mix of high-volatility monsters and sleek game design. If you’re hunting for a UK casino that hosts Money Train or Temple Tumble, you’ve landed in the right spot. This guide cuts through the bluster to rank real-money sites where Relax Gaming titles deliver the goods—and where bonuses don’t come with terms longer than a Dickens novel.
What Makes Relax Gaming a Standout Provider for UK Punters?
Founded in Malta in 2010, Relax Gaming started as a poker platform and transformed into a slot powerhouse. They’re not a one-trick pony: the company develops in-house hits, aggregates third-party studios via Silver Bullet and Powered By programs, and even offers a modest live casino. But the bulk of their fame comes from high-volatility online slots. RTPs typically hover between 94% and 97%, with many titles nudging 96.5%. That’s above the industry average—a quiet win for players who bother to read the paytable.
The UK market fell hard for Relax Gaming after the Money Train series exploded. Money Train 2, launched in 2020, became a cult classic; its bonus round can spit out payouts of up to 50,000x the bet, which is either life-changing or a fast track to disappointment, depending on your luck. The 2023 sequel, Money Train 3, raised the stakes with a 100,000x max win. Meanwhile, Temple Tumble and its Dream Drop jackpot variant gave casual spinners a sticky-wild thrill. Today, Relax Gaming supplies over 50 UK-licensed casino sites, from mega-brands to boutique operators. Integration is straightforward, so you’ll find their games tucked between NetEnt blockbusters and Play’n GO hits.
One thing to note: Relax Gaming doesn’t do dull. Their slots lean heavily into bonus buys, cascading reels, and features that trigger so often you’d swear the RTP is inflated—but it’s just clever math. For the player, that means session volatility can be brutal or beautiful. Quick bankroll swings are the norm. If you’re the sort who panics after 20 dead spins, stick to low-variance titles from other providers. Relax Gaming is built for rollers who can stomach the ride.
Top UK Online Casinos Offering Relax Gaming Slots
We’ve sifted through dozens of UKGC-licensed operators to spotlight the ones that do Relax Gaming justice. These aren’t random picks; each offers a substantial library of Relax content, fast payouts, and at least a semi-rational bonus structure. Flashy welcome packages often mean buried terms, so we focused on casinos where the fine print doesn’t read like a trap for the unwary.
Here’s our shortlist, followed by a comparison table for quick scanning.
Videoslots
The undisputed heavyweight for slot variety. With over 7,000 games, Relax Gaming’s catalogue is fully represented, from Money Train to niche titles like Hellcatraz. Payout times under 24 hours for e-wallets and a UKGC seal make it a top pick. Their welcome bonus includes a deposit match and free spins, though wagering requirements are standard—35x isn’t unusual.
Casumo
A quirky, adventure-themed casino that’s been a UK mainstay since 2012. Their Relax Gaming selection is curated but thorough, emphasizing high-RTP and feature-rich slots. The welcome deposit bonus comes with 35x wagering. Not saintly, but transparent. Withdrawals are generally processed within 48 hours.
LeoVegas
The “King of Mobile” takes Relax Gaming seriously. Their slot library leans toward premium, and you’ll find all the Money Train sequels, plus exclusive in-game promotions tied to Relax releases. Their welcome mix includes a deposit match and free spins. LeoVegas also offers a dedicated app, which is slicker than most.
PlayOJO
No-wager philosophy means what you win from free spins is actually cash. No string-betting nonsense. Relax Gaming slots feature heavily in their daily spin promotions. The downside: the site design feels like a 2015 flashback, but if you value transparency, it’s a solid pick. Their bonus structure is refreshingly straightforward—no wagering on free spin winnings.
Unibet
A betting giant that quietly built a stellar casino lobby. Relax Gaming slots are front and center, often with free spin giveaways tied to big sports events. The welcome offer is a deposit match, sometimes bundled with spins. Payout speeds rarely exceed 48 hours.
Rizk
Part of the Betsson group, Rizk carries many Relax hits. The Wheel of Rizk gamification adds a layer of amusement—though it’s more show than substance. Their welcome bonus typically pairs a deposit match with free spins. UKGC licensed and solid on mobile.
Betsson
A Nordic-rooted brand with a solid UK presence. Betsson’s casino floor includes the full Relax suite. Their welcome package is competitive, though wagering requirements are on the higher side. Live casino is above average if you fancy a blackjack hand between spins.
Dunder
Minimalist interface, but under the hood, Dunder’s filter system makes finding Relax Gaming slots a breeze. New titles appear within a day of release. The welcome offer is standard—deposit match, maybe free spins—but the payout speeds are competitive. A good choice for slot purists who don’t want distractions.
| Casino | Bonus | Relax Gaming Slot Highlight | UKGC Licence |
|---|---|---|---|
| Videoslots | Deposit match & free spins | Money Train 2, 3, Temple Tumble | Yes |
| Casumo | Welcome deposit bonus | Dead Man’s Trail, Volatile Vikings | Yes |
| LeoVegas | Deposit match & free spins | Money Train 3, Snake Arena | Yes |
| PlayOJO | No-wager free spins | Hellcatraz, Temple Tumble Dream Drop | Yes |
| Unibet | Deposit match | Money Train, Temple Tumble | Yes |
| Rizk | Deposit match & free spins | Money Train 2, Snake Arena | Yes |
| Betsson | Welcome package | All Relax titles | Yes |
| Dunder | Welcome offer | Money Train 3, Temple Tumble | Yes |
All operators listed hold a valid UK Gambling Commission licence. While bonus specifics change frequently, the types above reflect the typical offers. Always check the latest terms before depositing—what’s “free” today might be 50x playthrough tomorrow.
How We Picked the Best Relax Gaming Casinos for UK Players
We didn’t throw darts at a board of operator logos. Our criteria are grounded in what actually matters for a real-money slot session: game variety, speed of payouts, licence credibility, and bonus fairness. Any casino that makes it past our filter must have a UKGC licence. Without that, it’s not a casino—it’s a risk.
Game count isn’t everything, but we required at least 30 Relax Gaming titles in the lobby. More is better, especially when you factor in the depth of the catalogue. Some sites load up on ancient releases and call it a day; the ones we picked keep pace with new releases like Money Train 3 and the Dream Drop jackpots.
Payout speed is a proxy for how much respect an operator has for its customers. We favor casinos that process withdrawals in under 48 hours, with e-wallet options typically within the same day. Slow payers get scratched off the list. Bonus wagering requirements we accept up to 35x; anything beyond that feels punitive. A “welcome bonus” isn’t a gift—it’s a calculated liability for the house. They expect most punters to lose it back and then some. So read the terms like a contract, not a love letter.
Relax Gaming Slots: The Games That Deserve Your Attention
Relax Gaming’s portfolio currently sits north of 100 titles, but not all are created equal. The hits are genuinely innovative; the filler is, well, filler. Below, we’ve distilled the top picks that combine high RTP, engaging mechanics, and realistic win potential—though “realistic” in a Relax Gaming context means up to 100,000x your stake.
Money Train 2
The slot that turned Relax Gaming into a household name among UK punters. Released in 2020, it’s a 5×4 grid with 40 paylines, a 96.4% RTP, and a bonus round that’s part heist, part slot chaos. The max win of 50,000x is legendary. Volatility is extreme; dead spins are common, but the bonus buy option can catapult you straight into the action—for a price.
Money Train 3
The 2023 sequel pushed the max win to 100,000x with an RTP of 96.5%. The base game feels tighter, and the bonus round introduces new character modifiers that can multiply wins to grotesque levels. It’s not for the faint-hearted. If you’ve got a small bankroll, you might spend more time buying the bonus than actually playing.
Temple Tumble and Temple Tumble Dream Drop
An Indiana Jones-themed cascading slot with 6×6 grid, 46,656 ways to win, and a 96.25% RTP. The base game can deliver through its tumbling reels and free spins, but the real draw is the Dream Drop jackpot version—a progressive that seeds at €1 million. Yes, it’s a long shot, but the jackpot meter is always tempting.
Dead Man’s Trail
Pirate-themed with a board game bonus that’s oddly addictive. RTP is 96.29%, and the max win is 50,000x. The trail mechanic means you won’t just settle for a few free spins; you’ll navigate a map collecting multipliers and chests. It’s one of Relax’s most original concepts.
Hellcatraz
A pixel-art prison break slot with 51,840x max win and 96.46% RTP. It uses a unique reel set where symbols can expand to fill columns, and the free spins feature can go berserk with extra rows. High volatility, but the retro aesthetic gives it a weird charm.
Snake Arena
Less talked about but solid: a gladiator-themed 5×4 slot with a snake-charming bonus, 96.25% RTP, and a max win of 3,300x. It’s a mid-variance option in a catalogue heavy on extremes, so your balance won’t bleed out quite as fast.
| Slot | RTP | Volatility | Max Win | Key Feature |
|---|---|---|---|---|
| Money Train 2 | 96.4% | High | 50,000x | Persistent character modifiers |
| Money Train 3 | 96.5% | High | 100,000x | New Respins feature |
| Temple Tumble | 96.25% | High | 7,776x | Cascading reels, Dream Drop jackpot |
| Dead Man’s Trail | 96.29% | High | 50,000x | Board game bonus trail |
| Hellcatraz | 96.46% | High | 51,840x | Expanding symbols, pixel art |
| Snake Arena | 96.25% | Medium | 3,300x | Snake charm free spins |
| Volatile Vikings | 96.23% | High | 10,000x | Multiplier wilds |
RTPs are theoretical and based on the standard configuration; some operators may offer lower settings. Always check the game’s info page before loading up.
Bonuses and Promotions at Relax Gaming Casinos
Casino bonuses aren’t charity. They’re marketing spend with strings attached. That said, a well-structured bonus can stretch your bankroll and give you more shots at a Relax Gaming jackpot, provided you understand the terms.
The most common type is the deposit match welcome bonus—“100% up to £200” might appear, but the actual value hinges on the wagering requirement. At 35x playthrough on the bonus amount, you’d need to wager £7,000 before cashing out. That’s roughly 140 spins at £5 each, which can evaporate quickly on high-volatility slots. Free spin bundles tied to specific Relax titles like Money Train 3 are also popular. They often come with wagering on the winnings, but PlayOJO’s OJOplus model stands out by cutting that nonsense entirely—wins are cash, no rollover.
No-deposit bonuses are rare but exist, usually as a handful of free spins on registration. They’re a low-risk way to test a site, but the max cashout caps are typically lower than a Friday night kebab budget. Cashback offers are another breed—some casinos return a percentage of net losses over a week, usually 5–15%. For a £500 loss, you might claw back £50, which is better than a poke in the eye. Just note that cashback often has its own playthrough requirement.
Keep an eye on slot-specific tournaments. Videoslots and Casumo run regular races on Relax Gaming titles, adding a competitive edge to what’s otherwise a solitary pursuit. If you’re the type who likes a leaderboard, these can inject a little extra adrenaline.
Mobile Play: Relax Gaming on the Go
Relax Gaming builds its slots in HTML5, so they adapt to any screen without clunky downloads. The touch controls are responsive, and the graphics scale well—even on older phones, the frame rates hold steady. You won’t find a separate Relax Gaming app; instead, the casinos themselves provide either a dedicated iOS/Android app or a mobile-optimized site.
Testing across a stack of iPhones and Android devices, we noticed that LeoVegas and Casumo apps handle Relax Gaming titles particularly well, with quick load times and minimal battery drain. PlayOJO’s mobile site, while functional, feels a bit cramped on smaller screens. Videoslots’ app offers a one-tap login and a search function that actually works—a minor miracle in the casino app world.
One quirk: bonus buy features on mobile can be tricky because the in-game pop-up sometimes obscures the cost. Double-check the amount before you confirm, or you might accidentally drop £50 on a single feature without realizing it. The interface isn’t malicious, just poorly laid out. For the best mobile experience, stick to casinos that have invested in UX—it shows in the small details.
Payment Methods at UK Relax Gaming Casinos
UK punters have a solid range of payment options, and the casinos we’ve listed cover the essentials. Debit cards (Visa, Mastercard) are universally accepted, though some digital-only banks may flag transactions to gambling sites. E-wallets like PayPal, Skrill, and Neteller dominate for speed—withdrawals often land within hours. Trustly and paysafecard are also common, and a few operators accept Apple Pay for deposits, which is handy if you’re playing on an iPhone.
The real differentiator is withdrawal speed. Videoslots processes e-wallet payouts in under 12 hours on average; PlayOJO can take up to 24. Casumo typically within 48. Banks transfers are the slowest, sometimes stretching 3–5 business days. A handful of casinos offer reverse withdrawal, which sounds like a feature but is actually a temptation trap—resist the urge to cancel a pending cashout.
Minimum deposits usually sit at £10, though some sites accept a fiver. For a relaxed session on Money Train 3, you’ll want at least £50 to absorb the swing. Withdrawals at £10 minimum, but cashing out £1.50 in leftover bonus winnings will get you declined—sites have a £10 floor for payouts.
Safety, Licensing, and Responsible Gambling
Playing at an unlicensed casino in the UK isn’t just risky—it’s illegal from the operator’s side, and you lose the protections that come with UKGC oversight. Every casino on our list holds a valid licence, which means they comply with strict standards on fair play, anti-money laundering, and player fund segregation.
Relax Gaming’s slots are tested by independent labs for RNG fairness. The theoretical RTP is built into the game files, and casinos can’t manipulate it arbitrarily—though they can choose from several RTP versions. Always load the game’s help screen to confirm the RTP setting; some operators lower it by a few points, which nibbles at your long-term payback. It’s legal, but it’s cheeky.
Responsible gambling tools are mandatory: deposit limits, time-outs, reality checks, and self-exclusion via GamStop. We’d be cynical to call them generous, but they do work if you use them. The best sites integrate these features into the account menu without burying them three clicks deep. If a casino makes it hard to set a deposit cap, that’s a red flag.
New Relax Gaming Casinos Worth Watching in 2026
The UK market rarely sees a flood of new licences, but a few fresh-faced operators pop up each year. In 2026, keep an eye on brands that partner quickly with Relax Gaming’s Silver Bullet platform—that’s often a sign they’re serious about building a slot portfolio rather than just slapping up a few titles and calling it a day.
Some new casinos might launch with aggressive cashback deals or zero-wager spins to lure players away from the established order. It’s a gamble on both sides: they hope you’ll deposit; you hope they’ll pay out promptly. Our advice: test new sites with small deposits, check Trustpilot for withdrawal complaints, and never assume a shiny new lobby means a reliable operator. The flashiest launches are sometimes the ones that stumble hardest.
One trend to watch: crypto-friendly casinos nudging into the UK fringe. While the UKGC doesn’t licence crypto gambling directly, some platforms blend fiat and crypto payments while holding a Curacao licence. These aren’t our first picks for UK players—the lack of UKGC protection is a dealbreaker for anyone who values dispute resolution.
Can I play Relax Gaming slots for free in the UK?
Yes, most UK casinos offer demo versions of Relax Gaming slots without requiring a deposit. You can spin Money Train 2 or Temple Tumble in fun mode, using virtual credits. It’s a sensible way to test volatility and features before committing real money. Just don’t expect demo wins to turn into cash—they’re purely for practice.
What is the highest RTP Relax Gaming slot?
Relax Gaming sets RTPs flexibly, but the highest theoretical return on standard configurations is 97% on titles like Book of 99. However, not all operators offer that setting. Among widely available slots, Hellcatraz at 96.46% and Money Train 3 at 96.5% are among the top. Always check the in-game info panel, because the RTP can vary by casino.
Are Relax Gaming casinos licensed in the UK?
Any casino legally serving UK players must hold a licence from the UK Gambling Commission. All the casinos we recommend are UKGC-licensed. This ensures game fairness, data protection, and access to the GamStop self-exclusion scheme. If a site lacks a UKGC badge, don’t sign up—your rights are significantly weaker.
Do all UK online casinos offer Relax Gaming games?
No. While Relax Gaming has grown its footprint, not every UK operator stocks its catalogue. Major brands like Videoslots, Casumo, and LeoVegas are reliable hosts, but many smaller or legacy platforms rely on other providers. Before registering, use the casino’s search bar to confirm the availability of titles like Money Train—that saves disappointment.
Does Relax Gaming have a live dealer casino?
Yes, Relax Gaming operates a live casino studio, but it’s far smaller than Evolution or Playtech. The live games include standard roulette, blackjack, and baccarat, streamed in decent quality. For Relax Gaming slots fans, it’s a nice add-on, though not the main attraction. Our recommended sites tend to pair Relax slots with Evolution live tables for the best of both worlds.
