Best Relax Gaming Online Casinos UK 2026
Relax Gaming has shifted from a quiet game supplier to one of the most requested slot providers among UK players. The reason is simple: Money Train 2 alone did more for the brand than a decade of press releases. Players now search for ‘best relax gaming online casinos uk 2026’ not because of loyalty to a logo, but because the studio consistently releases high-volatility slots with mechanics that feel less like a lottery and more like a calculated risk.
This page ranks the UK online casinos that actually carry Relax Gaming slots, treat withdrawals seriously, and hold a UKGC licence. I have excluded operators that pad their lobbies with dead demos or bury bonus terms under seven clicks. The list is short on purpose. You will find the full comparison table below, but first a few words on what makes Relax Gaming worth the search.
No affiliate fluff here. Casinos are not charities. Every ‘free’ spin and ‘welcome package’ is a retention tool, not a gift. The good operators at least make the terms readable.
What Makes Relax Gaming Different?
Relax Gaming launched in 2010 and spent its early years as a platform provider for other studios. That background matters because the company learned distribution before it learned slot design. In 2021 Kindred Group acquired the remaining shares, but Relax Gaming still operates independently and supplies games to hundreds of casinos, including the ones on this page.
The studio’s signature is high volatility with layered bonus features. Money Train 2, released in 2019, set a new bar for bonus buy slots and still dominates search volume. The follow-ups, Money Train 3 and Money Train 4, pushed the max win potential higher, but the original remains the reference point. Temple Tumble, Iron Bank, and Snake Arena also built cult followings because they offer frequent feature triggers rather than dead spins for twenty minutes.

One thing to understand about Relax Gaming slots: they are not built for low-risk play. The RTP figures are competitive, mostly between 96% and 96.5%, but variance sits at the top end. You will lose small amounts for long stretches, then hit a bonus that either pays nothing or pays triple digits. That is the trade-off. If you want gentle entertainment, play something else. If you accept variance as the cost of high ceiling payouts, this provider delivers.
Relax Gaming also licenses the Megaways mechanic from Big Time Gaming for several titles, which means cascading reels and changing ways to win. The studio’s own ‘Relax Reels’ and ‘Buy Feature’ options give players direct access to bonus rounds for a multiple of the stake. Not every UK casino allows bonus buy because of UKGC restrictions, so check the game settings before you deposit.

Top Relax Gaming Online Casinos UK: Ranked
Below are the operators I would use if I wanted to play Relax Gaming slots with real money in the UK today. The ranking weighs game availability, withdrawal speed, bonus clarity, and mobile performance. Not every casino with Relax Gaming games made the cut. Some have terrible withdrawal reviews or hide behind vague bonus terms. I left them out.
1. Videoslots – The Slot Library That Never Ends
Videoslots built its reputation on having more games than anyone else, and that includes a deep Relax Gaming catalogue. The casino’s ‘Battle of Slots’ promotions add a competitive layer, but the real advantage is straightforward: you can find every Relax Gaming release, including new ones, without hunting through categories. Withdrawals are processed quickly, and the UKGC licence is rock solid.
One caveat: the sheer size of the lobby can feel overwhelming. Use the provider filter and save your favourites.
2. LeoVegas – Mobile-First and Relax Gaming Ready
LeoVegas has won awards for mobile casino experience, and Relax Gaming slots run smoothly on its native apps. The operator’s welcome bonus is standard fare, but the platform’s reliability and fast withdrawals make it a top pick. If you play mostly on your phone, this is the most polished option.
LeoVegas also lists RTP and volatility inside the game info, which few casinos bother to do. That small detail matters when you are comparing high-variance titles.
3. Mr Green – Licensed and Polished
Mr Green has been around long enough to know that trust beats flashy promos. The casino offers a curated selection of Relax Gaming slots, including Money Train 2 and Dead Man’s Trail, with clear bonus terms. Withdrawal times are decent, though not always instant. The UKGC licence and long track record push it above newer operators.
4. Casumo – Gamified and Quick
Casumo’s adventure-style loyalty system is a clever retention gimmick, but the casino also pays out quickly and carries a solid range of Relax Gaming titles. The bonus wagering is average, nothing special, but the platform’s speed and mobile interface are excellent. If you want minimal friction between deposit and play, Casumo works.
5. Rizk – Transparency and Speed
Rizk’s ‘Wheel of Rizk’ and no-nonsense bonus policy made it popular, and the casino still stands out for clear terms. Relax Gaming slots are well represented. Withdrawal times are above average, often processed within hours for e-wallets. The only downside is a smaller game selection than Videoslots, but quality matters more than quantity.
The table below expands the list to ten operators. All hold UKGC licences, all carry Relax Gaming slots, and all meet a basic standard of fairness.
| Casino / Operator | Welcome Bonus | Key Relax Gaming Slots | Payout Speed | UKGC Licence |
|---|---|---|---|---|
| Videoslots | Welcome package | Money Train 2, Temple Tumble, Iron Bank | Fast (0–24h e-wallets) | Yes |
| LeoVegas | Deposit match + free spins | Money Train 3, Snake Arena, Hellcatraz | Fast (0–24h e-wallets) | Yes |
| Mr Green | Welcome bonus | Dead Man’s Trail, Money Train 2, Temple Tumble | Fast to moderate | Yes |
| Casumo | Welcome package | Iron Bank, Money Train 2, Snake Arena | Fast (0–24h e-wallets) | Yes |
| Rizk | Welcome bonus | Money Train 2, Temple Tumble, Hellcatraz | Fast (0–12h e-wallets) | Yes |
| PlayOJO | No wagering free spins | Money Train 2, Iron Bank, Wild Chapo | Fast (0–24h e-wallets) | Yes |
| Unibet | Welcome bonus | Money Train 2, Temple Tumble, Snake Arena | Fast (0–24h e-wallets) | Yes |
| 888casino | Welcome package | Money Train 2, Temple Tumble, Iron Bank | Moderate (1–3 days) | Yes |
| Betsson | Welcome bonus | Money Train 3, Dead Man’s Trail, Hellcatraz | Fast (0–24h e-wallets) | Yes |
| SlotsMillion | Welcome package | Money Train 2, Snake Arena, Iron Bank | Fast (0–24h e-wallets) | Yes |
All bonus descriptions above are bonus types, not exact amounts. Specific numbers change weekly and depend on deposit size, so verify on the casino site before claiming. The point is that every listed operator offers a concrete welcome incentive tied to Relax Gaming slots or general play.

Relax Gaming Slot Portfolio: What to Play First
If you are new to Relax Gaming, start with Money Train 2. It is the flagship for a reason: the bonus round allows a persistent multiplier and collector symbols that can escalate payouts into absurd territory. The base game is dull, but the bonus frequency is acceptable. Money Train 3 and 4 offer higher max wins but lower hit frequency, so the original remains the best entry point.
Temple Tumble is a cascading grid slot with a destruction mechanic that removes blockers and opens positions. It feels less punishing than Money Train and suits players who want frequent small wins with occasional bursts. Iron Bank is a heist-themed slot with expanding wilds and a bonus buy option, but buy features are disabled at most UK casinos due to regulatory restrictions.
Here is a quick reference table for the most popular Relax Gaming slots among UK players. RTP values are approximate and taken from the provider’s published game sheets; volatility is my qualitative assessment based on extensive play data.
| Slot | Approx RTP | Volatility | Max Win Potential | Notable Feature |
|---|---|---|---|---|
| Money Train 2 | 96.4% | Very high | 50,000x stake | Bonus round with persistent multipliers |
| Money Train 3 | 96.1% | Very high | 100,000x stake | Expanded bonus features |
| Temple Tumble | 96.25% | High | 10,000x stake | Cascading reels with destruction |
| Iron Bank | 96.2% | High | 50,000x stake | Expanding wilds and bonus buy |
| Snake Arena | 96.25% | High | 5,000x stake | Free spins with wild chase |
| Dead Man’s Trail | 96.2% | Very high | 50,000x stake | Trail bonus with multipliers |
| Hellcatraz | 96.46% | High | 50,000x stake | Locking symbol feature |
| Wild Chapo | 96.4% | Medium | 15,000x stake | Sticky wild free spins |
Do not chase max win. The 50,000x figures are theoretical and require a series of events so unlikely that you could play daily for a decade and never see one. The realistic ceiling for most sessions is a few hundred times your stake, and even that is rare.
Relax Gaming Bonus Landscape: Read the Fine Print
UK casinos love to advertise ‘free spins’ and ‘no deposit bonuses’ with Relax Gaming slots. The word ‘free’ does heavy lifting, but the casino is not run by philanthropists. A typical welcome offer gives you a deposit match plus spins on a selected slot, often Money Train 2 or Temple Tumble. The catch is wagering requirements, usually between 35x and 45x the bonus amount. That means you must wager hundreds or thousands of pounds before withdrawing any winnings from the bonus.
No deposit bonuses are rarer in the UK than offshore sites, because UKGC rules require identity verification before any bonus is credited. Some casinos offer no deposit free spins after you verify your phone number or complete KYC, but the amounts are small — often 10 to 20 spins on a selected game. Treat these as a demo with a tiny chance of a real payout, not as free money.
Bonus buy features on Relax Gaming slots are not available at UKGC-licensed casinos. The regulator banned them because they allow players to pay a multiple of the stake to enter the bonus round directly, which accelerates losses. If you see a UK casino offering bonus buy on Money Train 2, it is either breaking rules or using a demo version. Avoid it.
When comparing bonuses, look at four things: wagering contribution of slots (should be 100%), maximum bet allowed during wagering (usually £5 or less), game exclusions, and time limits. A bonus with 35x wagering and a 7-day expiry is worse than one with 45x wagering and 30 days, because you cannot realistically clear the latter in a week without high-risk play.
Mobile Casinos for Relax Gaming Slots
Every UK casino on my list offers a mobile-optimised website or a native app. Relax Gaming slots are built in HTML5, so they run smoothly on iOS and Android without downloads. The main difference between mobile casinos is not game performance but navigation and payment integration. LeoVegas and Casumo have the best mobile interfaces. Videoslots offers an app but the web version is equally good.
One practical tip: set your phone to landscape mode for Relax Gaming slots. The bonus rounds, especially Money Train 2, have small symbols and multiple meters. Portrait mode forces the game to shrink everything, which makes it harder to follow the multiplier and collector values during the bonus.
Payments and Withdrawal Speed at UK Relax Gaming Casinos
UKGC-licensed casinos must process withdrawals within a reasonable time, but ‘reasonable’ is not defined. In practice, e-wallets like PayPal, Skrill, and Neteller are the fastest, often processed within 24 hours. Debit card withdrawals take 1 to 3 banking days. Bank transfer can take up to 5 days. The casinos on my list all offer e-wallet withdrawals, and most process them quickly.
Verification is the hidden delay. UK rules require casinos to verify your identity before your first withdrawal. If you deposit with a debit card, you may need to upload a photo of the card and a utility bill. Complete this step as soon as you register to avoid frustration later. The fastest casinos, like Rizk and Casumo, often approve documents within hours if they are clear.
Trustly and paysafecard are popular deposit methods at UK Relax Gaming casinos. Trustly enables instant bank transfers without sharing card details. paysafecard is a prepaid voucher, useful for controlling spending, but withdrawals cannot go back to paysafecard. You will need an alternative method for cashouts. PayPal remains the best all-round option because it is fast for both deposit and withdrawal and adds a layer of security.
New Relax Gaming Casinos UK: What to Look For
New UK casinos launch every month, and many include Relax Gaming slots in their lobby. A new casino is not inherently bad, but it carries risks: less tested withdrawal processes, smaller support teams, and sometimes aggressive bonus terms. I prefer operators with at least two years of UKGC operation, but the list above includes a few newer brands because they have proven reliable.
If you want to try a new casino, check three things before depositing. First, confirm the UKGC licence number on the website footer and verify it on the Commission’s public register. Second, read the withdrawal policy: any casino that mentions ‘internal review periods’ longer than 48 hours is hiding something. Third, test customer support with a simple question about game availability. Slow or evasive support is a red flag.
New casinos often offer larger welcome bonuses to attract players. That is fine, but the wagering requirements are usually the same as established operators. Do not let a bigger number fool you. A 200% match up to £200 with 45x wagering is mathematically worse than a 100% match up to £100 with 35x wagering if you only deposit £50, because the realistic expected loss from wagering outweighs the extra bonus.
How We Ranked These Casinos
The methodology is simple but strict. I started with all UKGC-licensed casinos known to carry Relax Gaming slots, then filtered them against five criteria.
- Game availability: At least 20 Relax Gaming titles, including Money Train 2 and recent releases.
- Withdrawal speed: Documented processing times under 24 hours for e-wallets, with no hidden delays.
- Bonus clarity: Terms visible before signup, with no misleading ‘free’ claims.
- Mobile performance: Smooth HTML5 play on both iOS and Android without crashes.
- Customer support: Live chat available at least 12 hours a day, with responsive UK-based agents.
I also considered reputation on player forums and historical complaints. Casinos with repeated unresolved withdrawal issues were removed, regardless of how many games they offer. The list is not exhaustive, but it represents the operators I would use myself.
Legal Status: Relax Gaming and UKGC
Relax Gaming holds a UK Gambling Commission supply licence, which authorises it to provide games to licensed UK operators. The UKGC is one of the strictest regulators in the world. Its rules ban bonus buy features, require transparent RTP display, and enforce strict responsible gambling tools. Any UK casino offering Relax Gaming slots must also hold its own UKGC operating licence and comply with GamStop self-exclusion.
Non-GamStop casinos with Relax Gaming slots exist, but they are not regulated by the UKGC and operate offshore. I do not recommend them. They may offer higher bonuses or no verification, but you lose all UK consumer protections. Withdrawal disputes are common, and you have no recourse through the UKGC or UK courts. Stick to licensed operators, even if the bonuses seem smaller.
Responsible Gambling at Relax Gaming Casinos
Relax Gaming slots are high variance, which makes them attractive to players chasing losses. That is the worst possible reason to play. Set a deposit limit before you open any game. Every UKGC casino must offer deposit limits, reality checks, and time-outs. Use them. If you need to self-exclude from all UK casinos at once, sign up for GamStop, which blocks access to every licensed operator for a chosen period.
There is no strategy that beats a slot. RTP is a long-term average over millions of spins, not a promise for your session. A high RTP does not mean you will win back 96% of your deposit. It means the house edge is 4% over infinite play. Your individual session variance can swing wildly, and most players lose. Accept that before you deposit.

Which UK casinos have Relax Gaming slots?
Most major UKGC-licensed casinos carry Relax Gaming slots, including Videoslots, LeoVegas, Mr Green, Casumo, Rizk, PlayOJO, Unibet, 888casino, Betsson, and SlotsMillion. The table above lists ten verified operators. Always confirm the game is live in your region after logging in, as some titles may be restricted.
Are Relax Gaming slots available on mobile?
Yes. Relax Gaming builds all its slots in HTML5, so they run directly in mobile browsers without downloads. LeoVegas and Casumo offer the best native apps, but any casino on my list works well on a phone. Use landscape mode for Money Train 2 and other feature-heavy slots.
Can I play Relax Gaming slots for free?
Yes. Every UKGC casino offers demo versions of Relax Gaming slots, including Money Train 2 and Temple Tumble. You do not need to deposit to access demos, but you must verify your age. Playing for free is the best way to learn bonus mechanics before risking real money.
What is the best Relax Gaming slot in the UK?
Money Train 2 remains the most popular and highest-impact Relax Gaming slot due to its persistent multiplier bonus and 50,000x max win potential. Temple Tumble is a softer introduction, while Iron Bank and Dead Man’s Trail appeal to players who want similar volatility with different themes. No slot is ‘best’ for everyone; choose based on volatility tolerance.
