Mr Rex is a UK online casino that opened in 2021 and operates under a UK Gambling Commission licence, account number 39335. The brand, written MrRex on its own site, belongs to ProgressPlay Limited, a Malta-registered white-label company that supplies the platform behind it. Its headline strength is sheer volume: more than 6,000 games, upwards of 1,100 live dealer tables, live bingo rooms and a sportsbook, all reached from a single account. Payments start at £10 for deposits and £5 for withdrawals.
Volume is not the whole story, though. The operator was sanctioned by the regulator in May 2025, payouts are handled on working days only, and reaching support was hit and miss at the time of review. This Mr Rex review walks through licensing, safer gambling controls, payments, the game library, mobile play, support and player feedback, so you can judge whether the Mr Rex casino suits the way you like to play.
Mr Rex at a glance
Mr Rex is a young UK casino with an unusually large catalogue, combining casino games, live bingo and sports betting behind one login. These are the core facts we confirmed at the time of writing:
- Launched: 2021
- Licence: UK Gambling Commission, account no. 39335
- Operator: ProgressPlay Limited, registered in Malta
- Games: 6,000+, including more than 4,000 slots
- Live dealer tables: 1,100+
- Smallest deposit: £10, rising to £20 on most methods
- Smallest withdrawal: £5
- Withdrawal pending period: 1 working day
- VIP programme: yes, built on points, levels and a Rewards Store
- Mobile app: none; the site runs in your phone’s browser
- Support: live chat and email, advertised as 24/7, English only
Two practical points stand out from that list. First, the minimum deposit depends heavily on the payment method, so the £10 figure only applies to a couple of options. Second, the low £5 withdrawal floor is generous, but the working-day-only processing schedule means a request made on a Friday evening can sit untouched until Monday.
How we reviewed Mr Rex
Mr Rex was assessed across six areas: licensing and safety, loyalty rewards and their rules, payments, games and usability, customer support, and reputation with players.
We applied the same checklist we use for every casino we cover. That meant reading the licence details and the operator’s regulatory history, going through the general terms and the reward rules, testing the cashier and the withdrawal process, browsing the lobby on desktop and mobile, contacting support through each available channel, and looking at what real players say publicly. We describe what we found rather than boil the casino down to a single number, because the right choice depends on what you value most: a huge game list, fast cash-outs or responsive help. You can read more about our team and methods on the about us page.
Is Mr Rex safe and licensed?
Yes, Mr Rex is licensed by the UK Gambling Commission under account no. 39335, though its operator faced UKGC regulatory action in May 2025.
Holding a UKGC licence is the legal baseline for any casino taking bets from British players. It obliges the operator to verify identities, keep minors out, follow anti-money laundering rules and provide safer gambling tools. Our guide to casino licensing explains what the licence covers in more detail. For Mr Rex, the licence itself is in order; the more nuanced question is how well the operator has met those obligations in practice.
ProgressPlay and the 2025 sanction
ProgressPlay, a white-label specialist launched in 2012, runs Mr Rex and provides its licence, platform and back office. In May 2025 the Gambling Commission sanctioned the operator after finding failures in processes linked to anti-money laundering and social responsibility. The action targeted the company rather than one brand, and it did not remove the licence, but it is a fact any cautious player should weigh. A casino can have a long list of games and still fall short on the checks designed to protect customers, so we treat this as the main mark against the site’s trustworthiness.
On the positive side, the brand has now been trading for around five years, and ProgressPlay is a well-established name in the UK white-label market.
Security and data protection
Mr Rex states that it protects connections with 128-bit SSL encryption and shields its systems behind a firewall. The site also displays Sectigo and PCI payment security certification, and it publishes a GDPR privacy policy explaining how personal data is handled. What’s missing is two-factor authentication. Without 2FA, your password is the only barrier between a stranger and your account, so pick a long, unique one and never reuse it elsewhere.
Age checks and UK gambling law
The Gambling Act 2005 sets the rules for every form of gambling in Great Britain, including online casinos. Under that framework, the UKGC requires licensed sites to confirm a customer’s age at registration and refuse anyone under 18. Mr Rex runs an electronic check when you sign up and asks for documents later, when you withdraw. Online gambling is strictly for adults: if you’re under 18, please don’t play.
Safer gambling tools at Mr Rex
Mr Rex provides deposit, wager and loss limits, time-outs, session limits, reality checks, self-exclusion and a monthly net-deposit budget, all set from your account.
The range is broad. Deposit, wager and loss caps let you control spending from different angles, while session limits and reality-check pop-ups remind you how long you’ve been playing. The monthly budget limit is calculated on net deposits, which is a useful way to cap real losses rather than turnover. If you need a longer break, you can take a time-out or self-exclude entirely. The safer gambling page also offers a self-assessment questionnaire, links to blocking software and contact details for specialist charities.
One gap stands out. To review your gambling history, you have to email customer support and request it, instead of downloading a report straight from your account. Anyone who wants to look at their activity in the moment, perhaps because they’re worried about it, has to wait for a reply, and that delay can matter.
Warning signs and where to get help
Gambling should only ever be entertainment, but it can cause real harm. Watch for these signals in yourself:
- feeling restless or anxious when you can’t gamble
- trying to win back money you’ve already lost
- using gambling to escape stress, boredom or low mood
If any of these sound familiar, reach out early. In the UK, free and confidential help is available from:
- GambleAware, on 0808 8020 133
- NHS Gambling Services, which provides specialist support
- GAMSTOP, a free self-exclusion scheme that works nationwide
- GamCare, which offers advice and someone to talk to
Mr Rex VIP programme and tournaments
Mr Rex runs a points-based VIP programme: completing missions earns points that raise your level, unlock badges and place you on a leaderboard.
Missions vary from trying a game you haven’t played before to triggering a particular slot feature. As you climb the levels, prizes can include special rewards and early access to newly released games. Points can then be swapped in the Rewards Store for cashback, bonus funds, free spins and other prizes.
Software studios also host tournaments on the site, where finishing high on a leaderboard can win cash and other prizes, and seasonal events appear throughout the year. Details of the current welcome deal, the reload packages, the midweek and weekend prize wheel and the daily mystery box are on our dedicated Mr Rex bonus page, together with their full terms. Promotional winnings at Mr Rex are subject to conversion caps, so read each set of terms carefully before you opt in.
Mr Rex payment methods
Mr Rex accepts ten payment methods, including debit cards, PayPal, Apple Pay and Pay by Bank, with minimum deposits ranging from £10 to £20.
E-wallet fans can choose between PayPal, Skrill, Neteller and Payz, while Visa and Mastercard debit cards cover the traditional route. Apple Pay and Instant Pay by Bank suit players who want quick, app-based payments, and PaySafeCard, Neosurf and PayviaPhone give you prepaid or pay-by-mobile options. Every deposit method credits your balance instantly. The table shows the limits for each one.
| Method | Minimum deposit | Withdrawal pending time | Withdrawal cap |
|---|---|---|---|
| PayviaPhone | £10 | — | — |
| PaySafeCard | £10 | 1 working day | None |
| Neosurf | £15 | — | — |
| Visa or Mastercard debit | £20 | 1 working day | None |
| PayPal | £20 | 1 working day | None |
| Apple Pay | £20 | 1 working day | None |
| Instant Pay by Bank | £20 | 1 working day | None |
| Skrill | £20 | 1 working day | None |
| Neteller | £20 | 1 working day | None |
| Payz | £20 | 1 working day | None |
PayviaPhone and Neosurf are deposit-only, and withdrawals back to PaySafeCard need a PaySafe online wallet. If you want to explore other sites that take these methods, see our pages on Apple Pay casinos and bank transfer casinos.
The minimum deposits are where Mr Rex looks less competitive. Most e-wallets and cards require £20, double the brand’s headline £10 figure, so low-stakes players are pushed towards vouchers or phone billing. A single £10 floor across every method would make the site friendlier to casual players.
Mr Rex withdrawal times and fees
A Mr Rex withdrawal stays pending for one working day on every method, and requests are only processed on working days, so weekends and bank holidays are skipped.
That schedule is the biggest drawback of the cashier. Ask for a payout on a Saturday morning and it won’t start moving until the next working day, and a bank holiday weekend adds yet another day. Once Mr Rex has approved the request, Instant Pay by Bank is the quickest route, with funds often reaching your account within a few hours. That speed carries a cost: the method deducts a 1% fee from each withdrawal, capped at £3.
The minimum cash-out is £5, which is low by UK standards, and support can authorise a smaller amount if you ask. Card and e-wallet withdrawals carry no stated maximum. For a wider look at quick operators, see our list of fast payout casinos and our guide to deposits and withdrawals.
How to withdraw from Mr Rex
Withdrawing takes four short steps once your account is verified:
- Log in and open the main menu.
- Select Cashier, then choose Withdrawals.
- Pick a payment method if you’re asked to, and enter the amount.
- Check the details carefully and confirm with the Withdraw button.
Verification documents
Mr Rex verifies you electronically when you register, then asks for physical documents before releasing a withdrawal. You can upload them securely from your account. Expect to provide:
- Photo ID: a passport, driving licence or government-issued identity card
- Proof of address: a utility bill or bank statement
Sending clear copies early avoids delays when you first cash out. Our KYC and account verification guide explains why casinos ask for these documents and how to prepare them.
Inactive account fee
Mr Rex charges £5 a month against any remaining balance once an account has gone unused for 12 months or more. The operator says it will try to return your money before the fee kicks in, but it’s simpler to withdraw what’s left if you stop playing. This rule is one of the less player-friendly parts of the terms.
Managing your money
Before you deposit, set a firm budget and limits you’ll stick to. Every casino game has a house edge, so the operator holds a built-in advantage. Only gamble with money you can afford to lose, and don’t treat gambling as an investment: over time, most players end up behind.
Mr Rex games
Mr Rex hosts more than 6,000 games, covering slots, live dealer and RNG tables, scratchcards, jackpot titles and live bingo rooms.
That makes the lobby bigger than those of many UKGC-licensed rivals. Demo mode is available on a large share of the non-live games, so you can try a title without staking real money, and you can save favourites to your profile for quick access. We didn’t find any exclusive games or branded live tables, but new releases are added regularly, so there’s usually something fresh to try. Our overview of casino games covers how each category works.
Slots
Slots make up the bulk of the catalogue, with over 4,000 titles spanning a wide range of themes, mechanics and RTPs. Established favourites such as Book of Dead and Gonzo’s Quest sit alongside newer releases including Le Bunny and Big Bass Trophy Catch. The weak spot is search: the lobby lacks filters for RTP, volatility, theme or feature type, so finding a high-volatility slot or one of the best payout slots takes manual digging.
Live casino
The live casino offers more than 1,100 tables, with many versions of roulette, blackjack and baccarat. Sic Bo and Andar Bahar are also available, but poker variants are thin on the ground. Most tables come from Evolution and Playtech Live, so you’ll find well-known titles such as Salon Prive Roulette and Speed 6 Scanner No Commission Baccarat.
Game shows and crash games
More than 30 game shows are listed, though the category filter was not working properly at the time of review, so most of them have to be found through the search bar. Titles include Red Baron and Ice Fishing, plus Stock Market, a crash-style game. If fast-paced multiplier games appeal, our guide to crash games explains the format.
Jackpots
Mr Rex listed over 180 jackpot games during our review, mixing fixed prizes with progressive pots. Most of the progressives belong to the Age of the Gods series, which suits players chasing a large one-off win, as long as you remember that the odds of landing a top prize are very long.
Game providers
The provider list is long, which helps explain the size of the library, and it includes smaller studios with quirkier themes alongside the big names. Among the developers on the site are:
- Playtech
- Pragmatic Play
- Light & Wonder
- Nolimit City
- Hacksaw Gaming
- ELK
- Rabcat
You can learn more about these studios in our game providers hub.
Sports betting and live bingo
Beyond the casino, the same Mr Rex account gives access to a sportsbook and live bingo rooms. That’s handy if you like to switch between a football bet, a bingo session and a few slot rounds without managing separate logins.
Playing fairly and safely
Every casino game has a mathematical edge in the house’s favour: you can win in the short term, but over time you’re likely to lose. Stick to UKGC-licensed sites like this one, where games are independently tested for fair, random results. Check each game’s rules and RTP before playing, as both vary from title to title, and treat gambling as paid entertainment rather than income. GamCare can help if it stops feeling fun.
Mr Rex on mobile
Mr Rex has no downloadable app, but its mobile browser site loads quickly and gives you the full game library.
In Google Chrome on a smartphone, logging in is quick, the whole catalogue is available, and making payments, opting into rewards and chatting with support all work without problems. Pages loaded fast and the layout felt smooth. In fact, the mobile version looks more modern than the desktop site, which feels dated in places. If you were hoping for a Mr Rex app, the browser version does the same job, and adding the site to your home screen gives you one-tap access.
Mr Rex customer support
Mr Rex advertises 24/7 support by live chat and email, but at the time of review emails to support bounced back and the chat widget kept disappearing.
Live chat opens with a bot that searches the help articles for an answer. Getting through to a human agent is easy, and the agents are helpful. The trouble is reaching chat in the first place: the widget appeared and vanished at random at the time of review, which could leave a player without help exactly when they need it. The chat button should be visible on every page.
Email is listed as customersupport@instantgamesupport.com, but the address is hard to find, appearing only in the general terms, and messages sent to it at the time of review were returned undelivered. Your experience may differ. No online contact form is provided, and support is available in English only.
The help centre is the strongest part of the service. It has a search bar and a large set of detailed articles covering most types of query, so many questions can be answered without contacting anyone.
Opening an account was straightforward, with a couple of steps and automatic verification. If a problem can’t be resolved with support, our guide to complaints and disputes explains your options.
What players say about Mr Rex
Mr Rex has very little public player feedback: at the time of review, its Trustpilot profile held only 27 reviews, with a low average.
A sample that small is not enough to draw firm conclusions either way, and a handful of unhappy customers can drag an average down quickly. We’ll revisit this once more players have shared their experiences. In the meantime, do your own safety checks before signing up at any casino; our guide on how to spot a scam casino lists the warning signs.
Mr Rex sister sites and alternatives
Mr Rex sister sites include Mr Slot, MrMobi and Mr Superplay, which also run under ProgressPlay Limited’s UKGC account 39335.
In a white-label set-up, one company holds the licence and supplies the software, cashier and back office, while each brand has its own name and design. You can compare the three in our Mr Slot review, MrMobi review and Mr Superplay review. To check whether any other casino belongs to the same group, look for the operator and licence account named in its footer or terms. Because the May 2025 regulatory action was taken against the operator itself, it is relevant to every brand on that account, not only Mr Rex.
Alternatives to Mr Rex
If what draws you to Mr Rex is the mix of sports betting, live bingo and a deep slot lobby, Paddy Power, Betfred and bet365 are worth comparing. Our guide on how to choose a casino can help you weigh them up on the points that matter most to you, from payment speed to support quality.
Pros and cons of Mr Rex
Mr Rex’s strengths are its huge game library and wide payment choice; its weaknesses are weekday-only payouts, unreliable support and the operator’s regulatory record.
Pros
- More than 6,000 games, including 4,000+ slots and 1,100+ live tables
- Demo mode on many non-live games
- Sports betting and live bingo under the same account
- Points-based VIP programme with a Rewards Store
- Ten payment methods, including PayPal, Apple Pay and Pay by Bank
- Low £5 minimum withdrawal
- Fast, modern mobile browser site
- Detailed, searchable help centre
Cons
- Operator sanctioned by the UKGC in May 2025
- Withdrawals processed on working days only
- £20 minimum deposit on most cards and e-wallets
- 1% fee, up to £3, on Instant Pay by Bank withdrawals
- £5 monthly charge on accounts left inactive for 12 months
- No two-factor authentication
- Few poker variants and limited slot filters
- Support email hard to find and unreliable in testing
Our verdict on Mr Rex
Mr Rex is worth a look if game variety is your priority, but weigh the operator’s 2025 sanction, weekday-only payouts and patchy support before you sign up.
The catalogue is genuinely impressive. With more than 6,000 games, a strong spread of providers, over 1,100 live tables, game shows, jackpots, live bingo and a sportsbook, few UK sites put this much under one roof. The mobile site is quick, demo play is widely available and the VIP programme gives regular players something to work towards.
The weaker areas are practical ones. Most card and e-wallet deposits start at £20, payouts wait for working days, the instant bank option costs a small fee, and support was difficult to reach at the time of review. Security is reasonable but would benefit from 2FA, and access to gambling history should be instant rather than by email request. Above all, the May 2025 sanction against ProgressPlay is a reminder that a licence alone doesn’t guarantee strong player protection.
In short, Mr Rex is best for players who prize choice and are comfortable with slower, weekday-bound cash-outs. If speed and responsive support matter more to you, compare the alternatives above or browse more reviews from our UK casino hub. Whatever you choose, set limits before you play and always gamble responsibly.
Frequently asked questions
Is Mr Rex casino legit?
Yes, Mr Rex casino is a legitimate site licensed by the UK Gambling Commission under account number 39335. It is run by ProgressPlay Limited, a Malta-registered white-label operator. Bear in mind that the UKGC sanctioned ProgressPlay in May 2025 over failures in its anti-money laundering and social responsibility processes, so the licence is valid but the operator’s compliance record is not spotless.
What are the Mr Rex sister sites?
Mr Rex sister sites include Mr Slot, MrMobi and Mr Superplay, casinos that also run under ProgressPlay Limited’s UKGC account 39335. They share the operator’s white-label platform, including software, cashier and back office, but each has its own name, design and promotions. The May 2025 UKGC sanction was taken against ProgressPlay itself, so it is relevant to all of these brands, not only Mr Rex. Check each site’s terms before signing up.
How long does a Mr Rex withdrawal take?
A Mr Rex withdrawal stays pending for one working day on every payment method. Requests are only processed on working days, so weekends and bank holidays add delays. After approval, Instant Pay by Bank can deliver funds within a few hours, though it deducts a 1% fee capped at £3. The minimum withdrawal is £5, and support can approve a smaller amount on request.
Does Mr Rex have a mobile app?
No, Mr Rex has no downloadable app. The casino runs in your phone’s browser instead, and in Google Chrome the mobile site loads quickly and gives access to the full game library, the cashier and live chat. It also looks more modern than the desktop version. Adding the site to your home screen gives you app-like, one-tap access.
What is the minimum deposit at Mr Rex?
The minimum deposit at Mr Rex is £10, but only with PayviaPhone or PaySafeCard. Neosurf starts at £15, while debit cards, PayPal, Apple Pay, Instant Pay by Bank, Skrill, Neteller and Payz all require at least £20. Deposits are credited instantly on every method, and the smallest withdrawal you can request is £5.
Is Mr Rex customer support available 24/7?
Yes, Mr Rex advertises round-the-clock support through live chat and email, in English only. At the time of review, emails to support bounced and the chat widget appeared and disappeared at random. Once connected, the human agents were helpful, and the searchable help centre answers many common questions without the need to contact anyone.
Does Mr Rex have live dealer games?
Yes, Mr Rex has more than 1,100 live dealer tables, supplied mainly by Evolution and Playtech Live. You will find many versions of roulette, blackjack and baccarat, plus Sic Bo, Andar Bahar and over 30 game shows. Poker variants are limited, so players focused on live poker may find the choice thin compared with the rest of the lobby.
