A practical UK guide to slot RTP and payout percentages in 2026, with a casino comparison table, high-RTP slots, and how to check real return-to-player figures. read the UK payout percentage guide
Relax Gaming doesn’t need a loud introduction. The studio has spent over a decade building slots that casinos actually want to feature. In the UK, the question is never ‘is Relax Gaming good?’—it’s ‘which licensed casino gives you the best overall package for playing those slots?’ This guide answers that. No fluff. Just a straight look at where to play, what to watch for, and why some ‘offers’ aren’t as generous as they look.
We’ve ranked the most reliable UK-facing casinos that stock Relax Gaming titles. All are licensed by the UK Gambling Commission. That matters because it means your deposits sit with an operator that has to follow real rules—not a faceless shell with a flashy banner. You’ll find a comparison table a few sections down, followed by breakdowns of games, bonuses, payments, and mobile play.
Relax Gaming started as a platform provider, then moved into game development around 2018. That background gives their slots a technical edge. The maths models are tight, the volatility is clearly labelled, and the feature designs often borrow from mechanics that other studios treat as afterthoughts.
UK players have always been picky about RTP and variance. Relax Gaming understands that audience. Their slots tend to land in the 94–98% RTP range, with many high-volatility titles that suit bonus hunters and patient grinders. You won’t find a dozen identical fruit machines here. Instead you get ideas like Money Train, Temple Tumble, and Iron Bank—each with its own risk profile and max win potential.
One more thing: Relax Gaming software is integrated into most major UK casino platforms. That means you can play the same game at five different operators and get subtly different experiences in terms of bonus terms, withdrawal speed, and support. The casino matters as much as the slot. That’s why we’ve focused on the operator, not just the game library.
We looked at four things: licensing, game selection, bonus fairness, and payout reliability. A casino with fifty Relax slots but no UKGC licence is useless. A casino with a huge welcome bonus but impossible wagering is a trap. And a casino that takes four days to process a withdrawal isn’t worth your time in 2026.
The comparison table below lists operators that clear all four bars. We didn’t include every casino that carries Relax Gaming—some are too new, some have shaky support, and a few have bonus policies that read like a riddle. The eight we’ve listed are the ones we’d actually use with our own money.
If you’re wondering why no crypto-only casinos made the cut, that’s deliberate. The UKGC doesn’t license pure crypto operators for UK residents, and offshore ‘crypto casinos’ lie about their licensing. Stick with the ones below and you’ll avoid that headache.
Here’s the shortlist. Each brand is licensed by the UKGC and offers a solid range of Relax Gaming slots. The bonus column shows what kind of welcome offer you can expect; we deliberately left out specific amounts because they change too often and are almost always capped or restricted. The type of bonus matters more than the advertised number.
| Casino | Bonus Type | UK Licence | Min Deposit | Payout Speed | Standout Feature |
|---|---|---|---|---|---|
| bet365 Casino | Welcome bonus | UKGC | Low | Fast | Large Relax slot library, reliable brand |
| 888casino | Welcome bonus + free spins | UKGC | Low | Standard | Original Relax exclusives |
| LeoVegas | Welcome bonus + free spins | UKGC | Low | Fast | Best mobile app for Relax slots |
| Casumo | Welcome bonus | UKGC | Low | Fast | Adventure-style loyalty tied to Relax play |
| Mr Green | Welcome bonus + free spins | UKGC | Low | Standard | Strong responsible gambling tools |
| PlayOJO | Free spins no wagering | UKGC | Low | Fast | Zero-wagering policy on most bonuses |
| Unibet Casino | Welcome bonus | UKGC | Low | Standard | Excellent Relax slot filtering |
| Betway Casino | Welcome bonus | UKGC | Low | Fast | High withdrawal limits for big wins |
| Videoslots | Welcome bonus | UKGC | Low | Fast | Biggest Relax Gaming slot catalogue |
| Grosvenor Casinos | Welcome bonus | UKGC | Low | Standard | Land-based trust, solid live dealer integration |
The table is a snapshot. Always check the operator’s current promotion page because UK regulations force constant updates to bonus terms. A ‘welcome bonus’ today might be a ‘free spins bundle’ in three months. The underlying casino quality doesn’t shift that fast, though.

Relax Gaming has a portfolio of roughly 200 slots, but only a handful dominate UK casino lobbies. Money Train is the flagship—a high-volatility game with a bonus round that can chain respins into five-figure multipliers. Temple Tumble and Iron Bank are two more that appear everywhere. All three share the same DNA: clear maths, sharp art, and max wins that sound outrageous until you grind them.
For lower-risk sessions, look at their classic fruit slots and the newer ‘Relax Classics’ line. These have simpler bonus features and RTPs closer to 97–98%. They won’t make you rich, but they stretch a £20 deposit further than a 20,000x max win game will.
One thing we respect: Relax Gaming publishes RTP and volatility information openly. No guessing. That makes it easier to match a slot to your budget. If you’re only depositing £10 a week, avoid Money Train 2. If you have a larger roll and want the thrill of a potential max win, go for it—but expect long dry spells.
A ‘welcome bonus’ at a UK casino is rarely what the banner suggests. The headline number might be £100, but the wagering requirement could be 40x, which means you’ll need to bet £4,000 before withdrawing. Free spins often come with a max win cap of £20. And cashback is sometimes paid as bonus funds with their own wagering.
That’s not a scam—it’s just how the industry works. UKGC rules force operators to show the true terms, but they still bury them in three-page PDFs. Our advice: always check the wagering contribution of Relax Gaming slots. Most UK casinos count slots at 100%, which is good. But some exclude high-RTP slots from bonus play. Read the list.
PlayOJO deserves a mention here. Their ‘no wagering’ approach means any free spins you get from a promotion are paid as cash. You can withdraw immediately, no rollover. The catch? The free spins themselves might be on a specific Relax slot with a low max win. Still, it’s closer to how a bonus should work. The casino isn’t a charity, but at least it isn’t pretending to be one.
Deposits are instant almost everywhere. Withdrawals are where operators differ. The UKGC requires verification before your first withdrawal, so have your ID ready. After that, e-wallets like PayPal and Skrill usually clear within 24 hours at the better casinos. Debit cards take 1–3 business days. Bank transfers can drag to five.
Fast withdrawal isn’t just about speed; it’s about attitude. A casino that processes your request within hours is one that isn’t hoping you’ll cancel and keep playing. The comparison table above notes which operators fall into the ‘fast’ category. If you’re a serious Relax slot player, pick one of those.

Minimum deposit amounts are uniformly low—usually £10 or less. Some casinos accept £5. That’s fine for testing a new Relax title, but don’t expect a £5 deposit to trigger a big welcome bonus. Most offers require £20 or more. Again, terms change, so verify before you commit.
Every casino in our table has a mobile-friendly site, and most have native apps for iOS and Android. Relax Gaming slots are built in HTML5, so they run in a browser without downloading anything. The experience is nearly identical across devices, though some bonus features feel cramped on a small screen.
LeoVegas is the standout for mobile Relax play. The app is fast, the search is decent, and the portrait mode works for most slots. Mr Green and Casumo are close behind. bet365’s app is functional but not as polished for slot play—it’s clearly designed for sports first, casino second.
If you prefer browser-only play, test a few Relax slots in demo mode first. That will tell you whether the touch controls annoy you before you risk real money. Mobile data is fine; these games load quickly even on 4G.

Playing Relax Gaming slots at a UKGC-licensed casino means your money isn’t at the mercy of some offshore shell. The UKGC requires segregated player funds, independent game testing, and effective complaints handling. If a casino messes up, you have a realistic path to resolution.
All eight operators in our table hold a current UKGC licence. Some also hold MGA or Gibraltar licences for other markets, but their UK presence is what matters here. Avoid any site that claims to offer Relax Gaming slots to UK players without a UKGC badge. That includes ‘non-GamStop’ casinos—they’re not licensed for UK residents, full stop.

Relax Gaming itself is licensed as a game provider by the UKGC. That means their RNGs are tested and their games can legally appear on UK casino sites. The provider doesn’t run casinos; it just supplies the software. So when you see ‘Relax Gaming casino’, think of it as ‘casino with Relax Gaming games’, not a standalone brand.
The UK market isn’t exactly overflowing with new licensed casinos—the UKGC has made licensing expensive and compliance heavy. But a few recent entrants have started stocking Relax Gaming titles from day one. These tend to be smaller operations backed by established platforms, so they can’t compete with bet365 on brand trust yet.
Our advice for new casinos: wait six months. Check forums for withdrawal complaints, see if their bonus terms change drastically, and confirm they actually pay out big wins. A shiny new site with a generous welcome bonus is often just a marketing budget with a bad support team.
That said, competition is good. New casinos force the incumbents to improve their bonus terms and payout speeds. If a new Relax Gaming casino offers a genuinely fair deal—low wagering, fast cashouts—we’ll add it to our table. Until then, stick with the proven operators.
Most major UKGC-licensed casinos carry Relax Gaming titles. The operator list includes bet365, 888casino, LeoVegas, Casumo, Mr Green, PlayOJO, Unibet, Betway, Videoslots, and Grosvenor. Each offers different bonus terms and withdrawal speeds, so the best choice depends on your priority—game variety, mobile experience, or cashout speed.
Yes. Relax Gaming is licensed as a software provider by the UK Gambling Commission. Their slots are legal on any UKGC-licensed casino site. Avoid unlicensed offshore casinos that offer Relax games to UK players; those operate illegally and offer no player protection.
For low risk, choose Relax classics with RTP above 97% and low-to-medium volatility. Some older fruit slots and simpler releases fit this profile. Avoid high-volatility games like Money Train if your budget is small, as long dry spells are common before bonus rounds trigger.

Yes, all UKGC-licensed casinos offer demo versions of most Relax Gaming slots. You can play without depositing or registering on many sites. Free play is useful for testing volatility and features, but you cannot win real money in demo mode.
No deposit bonuses are rare in the UK after regulatory changes. Some casinos may offer free spins without deposit as part of a promotion, but they almost always require a deposit to withdraw any winnings. PlayOJO sometimes runs no-wagering free spin offers, but check the current terms.
