Best Relax Gaming Online Casinos UK 2026
Relax Gaming started as a quiet supplier and turned into one of the most consistent slot studios in the business. Money Train 2 alone keeps thousands of UK players spinning, but the catalogue goes much deeper: Temple Tumble, Iron Bank, Snake Arena, Book of 99. The question is not whether Relax Gaming slots are worth playing. The question is which UK online casino gives you the cleanest way to play them.

This guide is built for UK players who want a shortlist, not a sermon. We tested the sites, checked the licences, compared bonus structures and looked at how Relax Gaming titles perform on desktop and mobile. No inflated promises. No ‘free money’ fantasy. Just a working list.
What Relax Gaming brings to UK casino lobbies
Relax Gaming is a software provider, not a casino operator. That distinction matters. The studio designs and licenses games to UKGC-licensed sites, which handle the payments, bonuses and player protection. In the UK market, Relax Gaming games appear across a wide band of operators, from big-name brands to smaller slot-focused sites.
The studio’s modern output splits into two broad camps: high-variance, feature-heavy slots such as the Money Train series and more balanced games like Temple Tumble and Book of 99. What unites them is a clean math model and a willingness to push bonus mechanics further than most. Persistent symbols, buy bonuses, respins and multi-level features are common. None of this guarantees a win, but it does make for sessions that feel less like a passive lottery.
RTP matters. Relax Gaming publishes a range of return-to-player values, with slots often sitting between 94% and 99%. A 99% RTP slot sounds generous, but that figure is a long-run average across millions of spins. Your evening session is noise. Anyone who tells you otherwise is selling something.
Relax Gaming also supplies a limited number of table games and live casino titles. The live product is not the main draw in the UK, but it does show up at a few operators. Most players come for the slots, and for good reason: the studio knows how to build a bonus round that keeps you thinking you are one spin away from a feature.

1. PlayOJO
PlayOJO built its brand on no-wagering free spins, and that still gives it an edge for Relax Gaming slots. You get what the label says, no hidden rollover gymnastics. The lobby includes Money Train 2, Temple Tumble and a steady stream of new Relax Gaming releases. Withdrawal requests are processed without drama, and UK licensing is clean.
2. Casumo
Casumo remains one of the more reliable homes for Relax Gaming slots. The interface is fast, the search works, and the game collection covers everything from classic Relax Gaming titles to the latest releases. Bonuses come with standard wagering, so read the terms. For rapid access to new slots, Casumo is hard to beat.
3. LeoVegas
LeoVegas pushes mobile play hard, and Relax Gaming’s HTML5 slots fit that brief perfectly. Money Train 2 runs smoothly on smaller screens, and the casino’s welcome package gives you a decent head start. The UK operation holds a full Gambling Commission licence and offers a broad range of payment methods.
4. MrQ
MrQ has kept things simple: wager-free spins and a clean slot-first design. Relax Gaming titles are featured prominently, and the lack of wagering on many promotions makes a real difference. It may not have the largest game library, but what it has is well curated.
5. 32Red
32Red is a UK stalwart. The site is not flashy, but it works. Relax Gaming slots sit alongside a large live casino and a reliable banking setup. The welcome bonus is standard, but the operator’s long track record in the UK market counts for something.

6. BetVictor
BetVictor offers a solid spread of Relax Gaming games, including several jackpot slots. The sportsbook background shows in the site’s efficiency. Bonus terms are clear, and withdrawals are generally processed faster than the industry average for UK players.
7. Betway
Betway’s casino platform hosts the full Money Train series and a good chunk of the Relax Gaming catalogue. The site is well regulated and offers live dealer games from multiple providers. The welcome bonus requires a deposit, but that is standard. Customer support is available around the clock.
8. Grosvenor Casinos
Grosvenor brings a land-based heritage to online play. Relax Gaming slots appear in the online casino alongside a deep live dealer suite. The welcome offer is straightforward, and you can collect points and rewards across both physical and digital venues.
9. All British Casino
All British Casino is aimed squarely at the UK market, with no wagering on its welcome bonus (check current terms). The Relax Gaming selection is smaller than some rivals, but the high-profile titles are there. Payments are handled in GBP with no currency conversion fees.
10. Videoslots
Videoslots is the slot library of record. Thousands of games, including dozens of Relax Gaming titles. The site sometimes feels crowded, but the filtering tools help. Its welcome package and ongoing races cater to volume players, though wagering requirements apply.
How we picked the best Relax Gaming sites
No list is useful without criteria. We looked at four things: UK Gambling Commission licensing, game selection depth for Relax Gaming titles, bonus fairness and withdrawal speed. Mobile performance mattered too, because most UK players spin on phones. We ignored affiliate kickbacks and never rank a brand just because it spends more on advertising.
A casino with a huge library but slow payouts drops down the list. A smaller brand with no-wagering free spins can beat a giant. This is not a popularity contest; it is a working guide.
We also check for responsible gambling tools: deposit limits, reality checks, time-outs and self-exclusion. If a site makes it hard to set a limit, it does not belong on the list. All ten operators above pass that test, even if some bonuses are less generous than others.
The Relax Gaming slots worth your time
Relax Gaming releases a steady stream of slots, but a few demand attention. Here is a short reference table with RTP profiles and volatility, so you can match a game to your own patience level.
| Slot | RTP Profile | Volatility | Notable Feature |
|---|---|---|---|
| Money Train 2 | 96.4% range | Very high | Persistent symbols, respins, large max win potential |
| Temple Tumble | 96.25% range | Medium-high | Cascading reels, free spins with increasing multiplier |
| Book of 99 | 99% | High | Expanding symbol, industry-leading RTP |
| Iron Bank | 96.2% range | High | Bonus buy option, heist theme |
| Snake Arena | 96.25% range | Medium | Free spins with snake wild |
Money Train 2 is the flagship: high variance, huge win potential, but long dry spells. Book of 99 is the opposite in one sense, with a 99% RTP, but that return is theoretical and spread over millions of spins. Do not confuse RTP with a guarantee.
For a more forgiving session, Temple Tumble and Snake Arena offer medium volatility without turning the game into a slot for toddlers. Iron Bank is for players who like a drama-filled bonus round and do not mind paying for it via bonus buy.
Newer releases like Cluster Tumble and Hellcatraz have their fans, but the five above are the best starting point. The trick is to try the demo first. Every UK casino on this list lets you play Relax Gaming slots for free before you risk real money.
Which Relax Gaming slot has the highest RTP?
Book of 99 holds the top spot with a 99% RTP. That figure is verified and unusual for a slot. It does not mean you will win 99% of your stake back every session; it is a long-run average. Still, compared with typical 96% slots, the difference is meaningful over thousands of spins.
Bonuses and free spins at Relax Gaming casinos
Welcome bonuses sound great until you read the terms. Wagering requirements, game weightings, time limits and max cashout clamps can turn a ‘generous’ offer into a maths problem. The best Relax Gaming casinos keep it simple: no-wagering free spins, clear deposit matches, no hidden traps.
PlayOJO and MrQ built entire brands around no-wagering free spins. That means what you win from free spins is real withdrawable cash, subject to standard verification, not locked behind a 40x rollover. Other operators, like Casumo and LeoVegas, offer larger welcome packages but with standard wagering. Neither approach is wrong; you just need to know what you are signing up for.
Reload bonuses and cashback offers appear weekly at some sites. Check the game weighting: Relax Gaming slots usually count 100% towards wagering, but not always. A bonus that excludes Money Train 2 is less useful than one that includes it. And yes, bonus buy features often do not count towards wagering at all, so read the fine print.
Do Relax Gaming casinos offer no deposit bonuses?
Some do, but they are rare and usually small. A no deposit bonus might be 10 free spins on a specific Relax Gaming slot, often Book of 99 or Temple Tumble. Read the terms carefully: max cashout limits are common. No deposit does not mean no strings.
Payments, withdrawals and UK licensing
Every casino on this list holds a UK Gambling Commission licence. That means segregated player funds, mandatory ID checks and access to the GamStop self-exclusion scheme. It is the baseline, not a bonus.
Payments are straightforward for UK players: debit cards, PayPal, bank transfer and sometimes Trustly or paysafecard. PayPal remains the most popular because withdrawals are fast and you avoid handing card details to a third party. Withdrawal times vary, but 24 to 48 hours is common after verification is complete.
Verification is not optional. You will send a photo ID and proof of address at some point. Casino forums are full of people complaining about ‘delayed’ withdrawals because they did not complete KYC. Upload your documents early and you will save yourself a headache.
Are Relax Gaming casinos legal and licensed in the UK?
Yes, the operators recommended here are licensed by the UK Gambling Commission. Relax Gaming itself holds a UK supplier licence, so its games are legal for UK players. Always check for the UKGC logo and licence number at the bottom of the casino site.
Can I deposit with PayPal at Relax Gaming casinos?
Most UK-facing Relax Gaming casinos support PayPal, including Casumo, LeoVegas and 32Red. PayPal deposits are instant and withdrawals are usually processed faster than card withdrawals. If PayPal is your preferred method, check the casino’s banking page before you sign up.
Mobile play and casino apps
Relax Gaming builds all its slots in HTML5, so they run in mobile browsers without a dedicated app. That said, many casinos offer apps for iOS and Android, and those apps often include Relax Gaming titles. The difference is negligible. What matters is that the games scale properly and the bonus buy button is not a pixel-wide trap on a small screen.
Money Train 2 is heavy on animations, so an older phone might struggle. If you have a mid-range device from the last three years, you will be fine. Data usage is modest; a longer session will not blow your monthly allowance.

Mobile play also changes how you use bonuses. Free spins on a small screen are fine, but navigating bonus terms is easier on a desktop. Do your research before you hit the sofa.
Do Relax Gaming slots work well on mobile?
Yes, Relax Gaming slots are designed for mobile play. They load quickly, resize correctly and support touch controls. Some older Relax Gaming titles can feel cramped on small screens, but the recent releases are mobile-first. Avoid playing on public Wi-Fi with any casino.
New Relax Gaming casinos and upcoming slots
The UK market does not see a flood of new casinos like it did five years ago, mostly because the UKGC tightened its rules. Still, a handful of new operators each year add Relax Gaming slots to their lobbies. The pattern is predictable: new sites launch with no-wagering free spins, a narrow game selection, and a promise of fast withdrawals. Some deliver.
On the studio side, Relax Gaming keeps a regular release schedule. Upcoming slots often appear first at larger operators like Casumo and Videoslots. Keep an eye on those two if you want early access. Do not expect a new Money Train every month; the studio takes its time.
New casinos tend to offer better welcome packages to attract attention, but check the licence first. A UKGC licence is non-negotiable. If a new site promises 500 free spins on Relax Gaming slots and no wagering, look for the catch. Usually the max cashout is low, or the spins are tied to a single high-variance game.
Crypto casinos and the non-GamStop temptation
Search for Relax Gaming slots and you will stumble across crypto casinos or sites claiming to be not on GamStop. They host pirated versions of the games, offer no UK consumer protection, and ignore self-exclusion. UK players have no reason to use them. The UKGC blocks most of these sites, but a few slip through with mirror domains.
Crypto payments are not accepted by UK-licensed casinos offering Relax Gaming games, because anti-money-laundering rules make it impractical. If a site insists on Bitcoin for a UK-facing Relax Gaming slot, that is a red flag. Stick to the licensed operators above, and you keep your money and your data safe.
Responsible gambling at Relax Gaming casinos
UK casinos are required to offer deposit limits, reality checks, time-outs and self-exclusion. Use them. A 99% RTP slot does not care if you are chasing a loss, and neither does the casino. Set a budget before you open the lobby, and treat any loss as the cost of entertainment, not an investment that will pay off later.

If you need help, GamStop offers free self-exclusion from all UK-licensed sites. GamCare provides counselling and a helpline. These tools are not a sign of weakness; they are the difference between a hobby and a problem.
One last point: the best Relax Gaming casino is the one that lets you play without pressure. The games are good. The operators on this list are solid. The rest is on you. Spin within your means, and do not believe anyone who tells you a slot is ‘due’ for a win. It is not.
