MrRex is a brand new online bookmaker that only launched in 2021. The site is owned and operated by Aspire Global, and is licensed and regulated in multiple jurisdictions, including the UK, Malta, and Sweden.  

We’ve already spent a great deal of time with the site, focusing on the mobile platforms, and have examined the betting markets, odds, bonuses, and much more besides. You can now find out exactly what we thought of our experience, and learn exactly what MrRex is all about. Ultimately, after reading this guide, you will have a great idea of whether the MrRex betting app is suitable for your needs.

MrRex Sign Up Offer 

MrRex has a little surprise in store for those who open a new account and place their first wagers on the app. All you need to do is register, make your initial deposit, and place £15 in bets. In exchange for doing so, MrRex will credit your account with a £10 free bet for the sportsbook. 

MrRex welcome offer

Here are the most significant terms & conditions for this MrRex free bet welcome: 

In short, you will receive your £10 free bet after you open a new account, deposit at least £10, and then place £15 in wagers on events with odds of 1/1 or greater. Once you have your free bet, you can use it on any live or pre-match event as long as the odds are 4/5 or greater. 

If your free bet wins, MrRex will credit you with the full win amount. In other words, if you use your MrRex £10 free bet on an event with even odds, then you would receive a total of £10 if the free bet wins. That cash would be yours to keep free and clear of any further conditions. 

Overall, this is a solid introduction to the MrRex mobile app. While we normally prefer the return on investment for these deals to be at least 1:1, getting £15 in exchange for a £10 spend still represents decent value.

MrRex Mobile App 

MrRex does not currently offer a native sports betting app. Whilst an actual mobile betting app would be nice though, mobile users don’t really need one to access everything MrRex has to offer. Instead, they can simply use their mobile browser.  

The MrRex mobile platform looks much like that of any other mobile bookmaker. Upon arriving at the main page, you are greeted by a sleek-looking and predominantly orange and white interface. You can choose to enter the online casino, live casino, or sportsbook by hitting the appropriate tab at the top of the main page. Head to the MrRex Sportsbook, and you’ll come across several popular live and pre-match offerings. You can scroll through the clearly displayed sports menu to find the sport and league you want to bet on. 

With a smart design that has the menus conveniently located, it really is a breeze to find your way around the sportsbook, and we were pleased with the overall user-friendliness and responsiveness of the MrRex mobile site. Even the most inexperienced user will have no problems navigating this platform, on either their smartphone or tablet. 

Other MrRex Apps

In addition to the sportsbook, MrRex features an online casino and live casino. There are no MrRex apps for these sections either, but – like the sportsbook – the casino and live casino games are mobile-compatible, which means you only need a mobile browser to use them. You can also deposit, participate in promotions, and contact the customer support team in this way.

Advantages of the MrRex Mobile App 

There are definitely some big advantages to using the MrRex mobile platform. To begin with, it allows you to access all of the bookmaker’s features wherever and whenever you want. As long as you have a steady internet signal, you essentially have full access to the site from anywhere you please. Let’s take a look at some of the other key advantages of MrRex’s mobile platform. 


The MrRex mobile platform provides the convenience of most other top-tier mobile bookmakers. It’s extremely easy to find the live or pre-match event you’re looking for, and to locate specific bet types, as each betting menu comes with a filter that enables punters to narrow their search. While we do believe the odds are a little difficult to read by default, you can easily change this by altering the visual appearance of the platform to your liking. 

Safe and Secure

You can be certain that MrRex mobile provides customers with high levels of security. Whether you are providing personal information while you are registering, or you’re entering your banking details while making a deposit or withdrawal, you can be 100% confident that your information is safe. 

MrRex achieves this by using the latest 128-bit SSL encryption technology, to make sure your details can’t be accessed by hackers, and there are also powerful firewalls in place. It also has an experienced security team on hand to keep an eye on all activities, so – if anything suspicious is going on with your account – MrRex will notice and act quickly. 

Banking Options Galore

The MrRex mobile site gives customers a great selection of fast and secure payment options. Whilst credit cards are no longer an option at UK sportsbooks, you can still use your debit card for deposits and withdrawals. MrRex mobile also supports online banking, as well as a variety of popular eWallets such as PayPal. 

One of the more attractive things about MrRex is that the sportsbook offers fast withdrawal times. In some cases, withdrawals are processed within mere minutes, which means you can collect your winnings quicker than you might at many other internet bookmakers. 

Live Betting

Perhaps you forgot to get your wager in before the game started, or you’re simply looking to hedge your pre-match wager. Whatever the motivation, MrRex lets punters get all the live in-play wagering action they can handle. 

You can use the MrRex mobile site to easily place wagers while a match is already in progress. Even though the live betting menu typically doesn’t offer as many wagering opportunities as the pre-match menu does, there are still loads of live betting options at your disposal, and the odds for these update pleasingly quickly.

Responsible Gambling Tools

MrRex does what it can to encourage you to gamble responsibly, providing several tools to help you out in this area. For starters, you can use your mobile device to set limits on the amount of time and money you spend on the site. You can even opt to enter a cooling-off period, while those who feel they may be showing signs of problem gambling can self-exclude entirely.

Great Selection of Mobile Casino Games

If you ever fancy a break from sports betting, you should definitely check out what the MrRex casino has to offer. You’ll find over 1,000 mobile casino games there, from over a dozen of the world’s finest software developers, including: 

Those who want to immerse themselves in the live dealer experience can also enjoy an array of live casino games from Evolution Gaming and Authentic Gaming. Whichever route you take, you’ll find extremely high performance levels – simply select the game you want to play, and it will load in your browser within seconds, then run smoothly thereafter. 

MrRex Betting Features 

To be honest, the MrRex mobile app isn’t exactly full of features. In fact, MrRex doesn’t have many features at all when compared to the bigger brands, and certainly none that are unique in any way. With that said, the mobile site does offer a few handy tools that will enhance your experience, and could theoretically help you to turn a profit. 

Cash Out

The cash out feature is a standard offering at online bookmakers these days. For those unfamiliar with the feature, this lets you close your wager before the match ends. 

Let’s say you placed a pre-match wager on Liverpool to beat Crystal Palace. Liverpool take a one-goal lead into half time, but Crystal Palace have taken all the momentum in the second half, and it looks like Liverpool are on the ropes. Instead of risking a collapse, you could trigger the cash out feature and lock in some profits immediately. Alternatively, you might use it to bail on a losing wager in other circumstances, and get at least some return on your investment.  

This feature isn’t available for every game, but you can find out if it is offered by using the “Select Market” tab in a match’s betting menu. Once a bet is placed, you can cash it out by selecting that option within your betslip. Your ticket will then display what MrRex is willing to pay you. If the price is right, then you can take the money and run. If not, you can ride out the wager. 

Unfortunately, unlike many modern brands, MrRex does not offer partial cash out. Instead, you must cash out all of the bet or none of it. 

In-Play Betting

We touched on in-play betting above, but it bears further exploration, since live betting is so wildly popular these days. Again, in-play lets punters place wagers while a game is in progress, which is a helpful feature on many levels. For starters, it gives you the ability to get a feel for the flow of a match before you wager on it. Live betting also gives punters plenty of opportunities to hedge their existing bets, or double down on them instead. 

The number of live wagering options at MrRex is pretty impressive. Some of the more popular live betting options for football include: 

The process of placing a live wager is the same as placing a pre-match bet. Simply find the in-play wager you want to make in the betting menu, select it to add it to your betslip, enter the wager amount, and submit it. Just be aware that the live odds are constantly changing as the match progresses, and – as such – you need to act fast to get the odds you want. It’s also worth mentioning that you can put live wagers in accumulators here, and some live wagers are even eligible for cash out. 

Whilst each live betting menu displays up-to-the-minute information such as the score and other live statistics, the MrRex mobile site does not support live streaming. This does put a dampener on the overall live betting experience, as – to make the most informed in-play picks – you’ll need to find another way to watch the matchup as it’s happening. 

Competitive Odds

Any seasoned sports bettor knows that getting the best odds is one of the most important facets of a profitable betting strategy. 

Overall, you could definitely describe the odds at MrRex as competitive, although they generally fall on the outer fringes of this classification. For example, while you can expect an odds margin of between 5.5% and 6% for two-way football wagers, the odds margins for three-way moneylines often exceed the 7% range, which is a little high. If you want to wager on a small-market event like a darts match, you could easily be looking at odds margins of 9% or above. 

These odds might be fine for newer recreational bettors who just want to have a little fun, but – in some cases – might dissuade experienced punters from signing up. Still, you will find some gems if you look hard enough, with the odds margins for plenty of markets hovering right around 5%.

Bonuses and Promotions

Technically, MrRex offers both loyalty rewards and a VIP program. Unfortunately, betting on sports doesn’t contribute to either. So, how does MrRex provide added value to sports bettors? 

We already mentioned the MrRex welcome bonus, which gives you a £10 free bet in exchange for placing wagers worth at least £15, at odds of evens or greater. Sadly, MrRex doesn’t have too much to offer sports bettors beyond that welcome bonus. A visit to the promotions reveals a MrRex casino welcome bonus and a casino slots contest, but there is nothing at all there for sports bettors; no cashback, no boosted odds, and no more free bets. 

This lack of sports betting promotions is pretty disappointing, particularly for a new online bookmaker that wants to become known in the UK sports betting market. Whilst the welcome bonus may attract some new customers, there isn’t really any additional incentive to keep them coming back. We can only hope that MrRex rectifies this unfortunate situation soon, if the bookmaker is to be a long-term success. 

Betting on eSports and World Events

The MrRex mobile sportsbook lets you wager on more than just real-world sports. They also cover a pretty good selection of popular eSports, like League of Legends and Dota 2. You can wager on regular league play here, or put your money down on some of the biggest eSports events around, like The International and the League of Legends World Championship. 

In addition, there are many “Specials” that MrRex provides every day. You can bet on upcoming presidential races in countries like Brazil, the United States, and the UK, or even on a variety of entertainment-related props, such as: 

MrRex Betting Markets 

If you can think of a sport, there’s an excellent chance that MrRex offers odds on it. MrRex covers every mainstream sport such as football, basketball, cricket, golf, and tennis among others. On top of that, there are plenty of small-market sports available to wager on, with cycling, curling, darts, snooker, and table tennis being just a few of the niche sports you’ll find at this mobile sportsbook. All told, this adds up to over 20 sports and hundreds of leagues and competitions. 

Each match typically presents punters with a wide range of betting options. These go far beyond simple Match Result picks, letting you wager on an assortment of player props, game props, and team props. If you don’t like the spread or total, you can choose an alternative handicap instead. There are plenty of great options for those who want to take short odds as well as those who like taking riskier picks, and some wagers – like Coin Toss Result – do not even require any knowledge of the sport at all. 


It’s no secret that football is the most popular sport on the planet, and – unsurprisingly – MrRex has prioritised its coverage of the beautiful game. It covers a wide range of major football leagues and competitions, like the English Premier League, Bundesliga, Europa League, and Italy’s Serie A. However, the bookmaker also features over 100 other leagues in dozens of different countries. You’ll find odds here on Chile’s Primera Division, the Ethiopian Premier League, Japan’s J1 League, and many others.  

It’s not just the vast number of leagues and matches that makes MrRex such an excellent bookie for football. It’s also the sheer number of betting opportunities that each game provides. Yes, the mainstream competitions typically offer more betting options than the more obscure leagues, but that’s to be expected. Some of the most common football bets include: 

Horse Racing

The MrRex mobile site brings horse racing betting action to you, wherever you are. The racing section covers events from several UK tracks, including Newcastle, Lingfield, and Ayr. Simply select the racecourse, the race you want to wager on, and then the horse you fancy to win. You can bet on a single horse in just one race here, or go deeper by putting together a horse racing accumulator.  

Admittedly, the horse racing betting at MrRex is rather limited compared to what other top-rated bookmakers offer. Still, considering the licensing difficulties involved with the ‘race of kings’, we’re pleased to see any markets at all being provided here.

MrRex Cheltenham Betting


One of the best things about being a tennis fan is that there always seems to be an event either happening or on the horizon. MrRex covers all major events including Wimbledon, the French Open, the Davis Cup, and many more like the Summer Olympics Tennis Tournament. 

You can place your outright wagers long before the tournament begins here, then wager on any match when the tournament’s underway. With the latter approach, you can bet on a match winner, or even the winner of a specific set. A few of the other intriguing tennis markets include:

Other Betting Markets

The MrRex mobile site goes far beyond simply providing markets on the biggest betting sports. You’ll also find almost two dozens further options here, with the list of more niche markets including:

As mentioned above, MrRex offers odds on other world events like politics and entertainment. Special mention should also be made of the eSports subsection, which provides a fantastic array of both pre-match and in-play markets on some of the most popular video games around.

Ongoing Promotions 

Those who expect their bookie to provide them with an array of promotions will be rather disappointed with the offerings at MrRex. We certainly were. Customers can claim either the £10 free bet bonus at the sportsbook, or they can claim a casino welcome bonus. The fun basically ends there though, unless you count entry into a single casino slots tournament, with absolutely no promotions available to sports bettors.  

We find this lack of sportsbook deals to be baffling. Almost all top bookmakers run regular sports betting promotions like enhanced odds, cashback, free bets, and reload bonuses. These offers are pretty straightforward to set up, and provide punters with a major additional reason to keep coming back and betting. In the case of MrRex, however, you are given no such incentive. 

Deposit Options and Banking 

To its credit, MrRex gives customers a good variety of quick and secure payment options. Deposits will instantly be shown in your MrRex account balance, while withdrawals are processed promptly. Whilst MrRex won’t charge you any fees to make these transactions, you should be aware that your payment provider may well do.

One important thing to note here is that you will need to complete the verification process before you can even make a deposit at MrRex. The good news, however, is that this is very easy to do. You will simply need to provide clear images of two documents. The first should be a government-issued picture ID, like a driver’s license or passport. This will verify your age and identity. The other document should be something like a recent utility bill or bank statement, that displays your full name and residential address, which will verify where you live. 

You can submit these documents by going into the “My Account” section and selecting the “Verify” link in your account details. You can then upload the documents and wait for MrRex to notify you that you have been verified. This can take up to a day, but it’s often done within an hour or so. Once verified, you can make as many deposits and withdrawals as you wish.

Customer Support 

If you have any questions or encounter any issues at MrRex, you can get in touch with a helpful and friendly customer service rep. However, whilst live support is available 7 days a week, agents only actually offer live help between 8am and midnight. 

During these hours, you can use the live chat feature to get in touch using your smartphone or tablet, and will typically connect with an agent in mere seconds. Alternatively, you can also send an email that details the question or issue. You could get a reply within an hour when taking this route, or you may need to wait several hours depending on the time of day and the complexity of the inquiry. If you’re outside of the customer service working hours, you can refer to the site’s FAQ instead. This section isn’t as comprehensive as we’d like to see, but it does cover a variety of topics, and the entries are fairly well-written and helpful.  


We can confidently tell you that both the MrRex mobile sportsbook and casino sections are highly secure. The site uses the latest 128-bit SSL encryption technology to protect you and your sensitive information, and any details that the site retains are safeguarded by state-of-the-art firewalls and a security team. 

Another sign that MrRex is secure and 100% legit is that it is licensed in the UK, Malta, and Sweden. These are among the most respected gambling authorities in the world, and they hold operators to the highest standards. Whilst having the casino’s RNG and games certified by iTech Labs has nothing to do with sports betting, it also tells us that MrRex is dedicated to fair play. 

About MrRex 

Having only been founded in 2021, there really isn’t a lot of information about MrRex itself. Still, we ran a search for MrRex online, to gauge its wide reputation with the betting public, and found no red flags to report. 

We do know that Mr Rex is licensed and regulated in the UK, which does a lot for the site’s credibility, and that it’s powered and operated by Aspire Global International. This is a respected company, which also runs several other established sportsbooks and casinos. Finally, like its parent company, MrRex is based in tax-friendly Malta.

Final Thoughts

After spending a lot of time on the MrRex mobile sportsbook, our verdict is a bit of a mixed bag. We should start by saying that the site is definitely legit, even if it isn’t well-known. The UKGC and MGA don’t license online bookmakers unless they can prove they operate with integrity. You can be sure that you and your information are well protected, and that your money is safe and secure. 

The bottom line, however, is that MrRex is nothing special. It offers fair odds on a wide variety of sports and other events, but it isn’t difficult to find better odds and more betting markets elsewhere. We won’t complain about the £10 free bet offer, which is in line with what you’ll find at other online bookmakers, but we will take issue with the lack of promotions and punters’ inability to earn loyalty rewards and VIP perks through sports betting. Existing customers who demand these things have little reason to stick around. On top of that, there’s a lack of features which are generally commonplace on modern-day mobile sportsbooks, such as a bet builder and enhanced prices.

That said, we were satisfied with the available payment options and withdrawal times. If you make a withdrawal request at the right time using the right method, you can receive your withdrawal within minutes, which is very impressive indeed. We did also receive competent and professional support, although it would obviously be much better if this was provided 24/7. 

Overall, the MrRex app isn’t exceptional by any means, but it’s a solid offering. We can’t fully recommend it in its current iteration, but this brand is still very young, and has plenty of potential to grow in the months to come. 


Is there a MrRex mobile app?

No – the site does not offer a dedicated betting app. You don’t really need one, however, because the site is skilfully configured for mobile browsers. As long as your mobile device has an internet signal and a browser, you’ll have full access to the bookmaker and all of its features. 

Is there live streaming available?

MrRex does not currently support live streaming, on either its desktop or mobile platforms. You can follow the live action using MrRex’s animated scoreboards though, which are found in each match’s betting menu. 

Does MrRex offer a sportsbook welcome bonus? 

Yes. When you sign up at MrRex, deposit at least £10, and then place £15 in wagers on events with odds of 1/1 or greater, MrRex will give you a £10 free bet that you can use on any live or pre-match event with odds of 4/5 or greater. 

Why do I need to complete the verification process? 

Like all online bookies that are licensed in the UK, MrRex’s licensing agreement requires the operator to verify each customer. This process is designed to combat underage gambling, money laundering, and other forms of fraud like identity theft. 

Can I place limits on my gambling activity at MrRex? 

Yes. MrRex is dedicated to promoting responsible gambling, and offers a variety of tools and resources to help keep your sports betting under control. It’s very easy here to go into your account profile, and place limits on the amount of time and money you spend at the site.
