MrRex Welcome Offer

MrRex New Customer Welcome Bonus

Here at our interest is always piqued when a new brand launches into the already packed online sportsbook market in the UK. So when MrRex announced it was joining the battle for your custom we were delighted to give it a whirl and check out the welcome bonus, markets and promotions on offer.

Our experts have given the site a thorough review so we can offer up our unbiased opinion on the ins and outs of the brand, which only launched in 2021. With a snazzy orange, white and black colour-theme and cool-looking mascot in the eponymous MrRex, the site certainly stands out from the crowd.

And while the bet £15 get a £10 free bet Welcome Bonus isn’t anywhere near as high as many of its competitors, it’s a decent offer and gives you a chance to try out the sportsbook and see what’s what.

As soon as you enter the sports betting section of the site you’ll notice that there are more than 30 sports available to bet on and dozens of markets for almost every professional event around the world. As you may expect, football features heavily among the options and all the big horse races are covered. So if you’re looking to bet on the Premier League or the Bundesliga, the racing at Newcastle or the greyhounds in Sunderland MrRex has it covered.

On top of the sportsbook you’ll also find a top class casino product at MrRex, with dozens of slot games, table games, live casino games and much more.

Why Do I Need a MrRex Welcome Bonus?

First things first – the initial question is always why should I get this MrRex Welcome Bonus? Well, they say variety is the spice of life, and like many bettors we’re always on the lookout for a new brand, especially when they give you a nice bonus to start off with. That’s of course, as long as you know the company that runs it is reliable and regulated.

MrRex ticks all these boxes. Owned by Cypriot Company MrRex Limited, the site is powered by Aspire Global, regulated by the United Kingdom Gambling Commission and offers all of the main sports markets you’d expect to find.

The Welcome Bonus is a classic bet £15 get £10 free bet offer. All you need to do is deposit and place £15 worth of bets and you’ll automatically find a £10 free bet in your account to use within 14 days on any bet with odds of 4/5 (1.80) or higher.

Free Bets have become one of the most recognisable types of betting bonuses offered by online bookmakers the world over, particularly in the UK. The big advantage is that you don’t lose anything if the bet doesn’t come off which allows you to try out different sports and markets you might not have otherwise bet on. Punters also often like to use their free bets on wagers with bigger odds than they might usually. This is where accas and bet builders enter the equation. If you’re not betting your own money it’s always worth sticking your free bet on a nice acca with odds of 10/1 or more. If it’s a winner you’re happy, if it’s a loser then no worries.

One point that caught our eye immediately is that there are no wagering requirements on the winnings from the free bet. This means you can withdraw the winnings immediately with no strings attached. It’s a much better deal than many other bonuses that require you to wager your winnings a number of times before you can make a withdrawal.

MrRex Welcome Bonus – How to Claim it!

Claiming your MrRex Welcome Bonus is easy as pie. The site is set out in a straightforward manner, so all you need to do is sign up and you’re good to go.

But just so it’s absolutely clear, here’s a New Kids-style step-by-step guide to claiming the welcome offer:

  1. Click on the “Claim” button in this review to go to MrRex
  2. Select “Sportsbook” at the top of the page
  3. Click on the “Bet £15 get £10” banner
  4. Complete the registration form
  5. Deposit £15 or more
  6. Make bets totalling £15 or more with odds of evens (2.0) or higher
  7. Check your free bet balance and you’ll have a £10 free bet waiting for you

As well as being aware of the conditions you’ll need to fulfil when claiming your welcome offer, you should also check the TnCs of the Free Bet Token as it can only be used on a bet with total odds of 4/5 (1.80) or higher.

What is the Best MrRex Welcome Bonus?

As you’ll see when you open up the MrRex website, even though it is a new brand there are a few different offers already available to new players. The most attractive of these are the Sportsbook Welcome Bonus and the Casino Welcome Bonus. As a new player you can claim both of these separately, as the balance for sports and casino is kept separate and bonuses can only be used on the respective products.

The MrRex sportsbook bonus might not be the most competitive around, but it’s straightforward and trustworthy. You get what’s promised to you with no concerns. The MrRex casino welcome offer is equally attractive. It offers new players a 100% bonus up to an impressive £200 PLUS 100 free spins on their game-du-jour, which is a good deal in anyone’s book. At the time of writing the free spins can be used on classic slot game “Starburst”.

MrRex Casino Welcome Bonus Up to £200

MrRex isn’t just a sportsbook! It also includes a solidly impressive casino for you to chill out at when you’re not placing those all-important sports bets. And when you sign up you can immediately claim their 100% up to £200 bonus. The bonus only applies to your first deposit, which means MrRex will match your deposit amount with a bonus of up to £200. This gives you the opportunity to try out their huge range of casino games – from jackpot slots to table games like blackjack and baccarat.

On top of this you also get 100 free spins on the “Starburst” slot. This is a great high energy game which has five reels and three rows with ten paylines which payout both ways.

Although it doesn’t show off many of the bells and whistles of newer slot games, it does include expanding wilds and respins. Note though, you don’t get the spins on your first deposit, but when you make a second and third deposit of £20 or more. You should also note that the spins expire after just 24 hours, so make sure you use them before they disappear.

MrRex Live Casino Welcome Bonus Up to £200

Like almost all reputable online casinos, MrRex includes a live casino option on the site. With an enormous range of over 75 live games to choose from this is one impressive option. Try your luck at one of the many live baccarat tables, roulette wheels, or blackjack tables. Or give an alternative live game like “Football Studio” a go.

Our personal favourite is the always enticing “The Strip Blackjack”. But don’t get any ideas – there’s no requirement to take off any articles of clothing! The word “strip” refers to the Las Vegas strip of hotels, not anything else.

While MrRex does not offer a welcome bonus that’s specific to the Live Casino, you can use your casino welcome bonus on any live casino games, which is good to know. Live Casino is great for players who enjoy the interaction of a real life casino but want to experience it from their own home. Each of the tables is run from a live location and features a live dealer via high speed videolink.

If You’re Having Problems Obtaining the MrRex Welcome Bonus…

If you’ve made a deposit and don’t seem to have received your MrRex Welcome Bonus there could be a problem. But don’t worry, MrRex has a professional customer support team on hand 7 days a week from 8am to 00.00am CET.

Before you contact the support team you should first make sure you’ve fulfilled the Terms and Conditions requirements listed on the site.

For the sports welcome offer you first need to deposit a total of £15, with each deposit being of at least £10. Be aware though, if you make a deposit using PayPal, Neteller, Paysafe, Skrill or Skrill 1-Tap it won’t be eligible for any Free Bet Token offer.

Once you’ve made your qualifying deposit you need to place a bet of at least £15 with odds of at least evens (2.0). You should then see the £10 free bet in your free bet balance. This bet must be made on a single or straight accumulator and be settled within 14 days of bet placement. And if you cash it out you won’t qualify for the free bet.

For the Casino welcome bonus you just need to make a deposit of at least £10. MrRex will then give you a bonus worth exactly the same amount as you deposited, up to £200. So if you deposit £100 you’ll get a £100 bonus. But if you deposit £300 you will get a £200 bonus. Like with the sportsbook bonus, you can’t get it if you deposit using PayPal, Neteller, Paysafe, Skrill or Skrill 1-Tap. The free spins will appear in your account after you’ve made another two deposits of at least £10 each.

If you’re sure you’ve done everything correctly but you still haven’t received the free bet then you should definitely contact support. Just click on the support link and either enter the live chat or fill out the form to send the team an email. MrRex has already garnered a good reputation for customer support, so you can expect a quick response.

Like at all the best online gaming sites, the welcome bonus is just the beginning of your betting journey at MrRex. It may be one of the New Kids on the Block, but it’s clear from the get-go that the site’s managers have put considerable effort into developing the offering so it provides a quality alternative to many of the big names out there.

At the same time, you can’t brush over the fact that the brand is clearly only at its starting point and lags behind the big boys in many respects. For example, as of early February 2022 there are only two promos on the site before you log in: the casino and sports welcome bonuses. Also, although the sports betting options cover all the bases they don’t go above and beyond. And there is no mobile app or live streaming available at all.

Read on to get all the details and our personal view on MrRex.

MrRex Design and Betting Opportunities

When it comes to site design and branding, MrRex makes its mark with a memorable orange, white and black colour scheme, bow tie logo and MrRex character. The character reminds us of the famous Mr Green from the casino brand of the same name. It will be interesting to see how much the company invests in marketing around MrRex because the Mr Green character was central to its brand marketing.

The brand has attempted to paint itself as a classy betting option, with clean lines and fonts used throughout. However, the more you browse the site the more you notice minor design glitches dotted around and the site seems rather sparse.

While the sports betting and casino sections share a colour scheme they have very distinct designs. Both are nice and user-friendly. And even though there is no mobile app available (at least at the time of writing), the website is built on a responsive platform which ensures it is just as accessible when viewed on a smartphone.

The sports betting section offers an excellent user experience with quick links on the left, live and upcoming events in the centre and the betslip on the right. The casino lobby allows you to filter the numerous games by slots, classic slots and table games.

There is no lack of betting opportunities at MrRex – whether you are betting on sports or casino. The sportsbook covers all the major sports and events, from football to tennis, American sports and of course horse racing. Then there are numerous less popular options like table tennis, futsal and even floorball. The odds are nothing to write home about – you’re unlikely to find many challenging the likes of Bet365 – but for casual bettors they are totally fine. On the casino side, you’ll have access to dozens of games from many of the top providers, including NetEnt and Microgaming.

MrRex Social Responsibility

Responsible gaming has become a major issue in the UK gaming scene over the last 5-10 years. So it’s no surprise that MrRex takes it very seriously. The Responsible Gaming page is extensive, giving details of a dedicated RG team within the company’s customer support department, all of whom have received GamCare Social Responsibility and Interaction training.

The site includes what it describes as “an extensive range of controls to help you play responsibly.” These include the option to impose Deposit Limits, a Cool Off Period, Self-Exclusion and Reality Check on yourself to prevent you from exceeding your gambling limits.

MrRex notes that it is committed to what is now known as “CARE” – Customers Are Really Everything. And from what we’ve seen so far this is not only a slogan. The customer support team has been very attentive whenever we’ve been in touch and have shown concern for any problems we’ve encountered.

MrRex Payment Methods, Currencies, Languages and Odds

As it’s a new brand MrRex does not offer a wide range of payment methods, currencies, languages and odds when compared to the more established names. However, it has made a good start and you’d expect this to improve over time.

Payment Methods

When you’re making a deposit or withdrawal at MrRex you currently have a choice of six options:

  • Mastercard
  • Visa
  • Skrill
  • Neteller
  • Muchbetter
  • Ecopayz


While British players are almost certainly going to be depositing in GBP, it’s interesting to see just how many different currencies the site accepts. Make sure you check which currencies are available for your favoured payment method, because some of the payment methods accept more currencies than others.

If you’re using a Visa card to deposit you can do so in no less than 11 currencies, including Euros, GB Pounds, US Dollars, New Zealand Dollars, Australian Dollars, Swedish Krona and more.


At the time we conducted this review, MrRex appeared to be available only in English. But considering the brand only launched last year I’d watch this space as there’s every chance more languages will be added in due course.


If you’re planning to place sports bets at MrRex then we need to talk about the odds. And, as we said, they’re not bad at all. Of course it depends which sport and event you are betting on, but overall you can see the traders are being firm and fair with their odds policy.

One of its big advantages is in the rapidly growing sector of Esports. You get quality odds on all the different Esport competitions from around the world, including DOTA and League of Legends.

MrRex Contacts

We can’t paper over the fact that your options are limited when you want to get in contact with the team at MrRex. This could very well be a concern for the more seasoned bettors among you, especially those who like to gamble after hours, when you get home from work for example.

Right now you can only contact the MrRex support team either via live chat or by sending an email – either through the online form or directly at [email protected] There is no dedicated phone number, twitter or other point of contact. On top of this, the support team is not available round the clock – you can only get in touch between the hours of 8am to 00.00am CET.

That being said, they are available seven days a week and from what we’ve seen from our’s and other users’ experiences they are knowledgeable and quick to respond to messages.

MrRex Summary

So what’s our overall verdict of MrRex.

If you judge the brand against the most established names in the business there’s no doubt it falls short on various fronts – from payment methods to odds as well as the lack of live streaming and a mobile app.

However, clearly this is just the start of the road for MrRex and it has built a very strong base for the future.

The usability and design show enormous promise and we’d expect to see more promotions, payment methods and contact options added as time goes by.

Frequently Asked Questions (FAQ)

The big advantage of Mr Rex is that while it is a very new sportsbook, it is part of the experienced Aspire Global group and is fully regulated by the UK Gambling Commission. This combination means you will benefit from the eagerness to please that they have as managers of a new brand along with the safety and security of regulation and certification.

MrRex appears to be safe and regulated. It utilises the latest 128-bit Secure Socket Layer (SSL) encryption technology to ensure that sensitive data is transferred securely over the internet to our secure server, which is protected by the latest firewall.

In a word, No! Even though the Mr Rex support team is attentive and aware, it is only available between 8am and midnight Central European Time. That is definitely a mark against this new brand and we hope the support availability will be expanded in the near future.

While you can cash out your bets before the event is finished, MrRex does not seem to offer partial cash out. This is another illustration of the limited options at this brand, and once again we are looking forward to seeing more betting benefits and promotions added in due course.
