UK bettors are spoiled with yet another new gentleman bookie in the form of Mr Rex. This is no Tyrannosaurus, as MrRex provides players with a modern yet simple betting experience that is available on all devices. Launching in late 2021, the bookmaker offers players a no-nonsense site with all the sports you need.

All practical matters have been handled well from deposits and withdrawals to customer support, while the site is also very fast. Casino services are also provided at MrRex, and with a lot of loyalty promotions to be enjoyed there's plenty of value for money to be found.

This is what Mr rex sports betting looks like on mobile


Expert's review Jamie Smith

Sportsbook tested

Mr Rex is one of the online bookmakers to use the Aspire Global platform, which has both pros and cons. Users will be familiar with the layout and navigation, but the site is not the fastest.

There is also a sense Mr Rex is more focused on its online casino than the sportsbook side.

With fees charged on both deposits and withdrawals at Mr Rex, this will probably put some potential players off from choosing this sportsbook.

With no Android or iOS mobile app, no live streaming and no 24/7 customer service provided, many of the things that sports fans now take for granted are currently missing at Mr Rex.

But decent promotions, a good range of sports to pick from and solid odds means that it might be worth giving the Mr Rex sportsbook a go anyway.

Overall rating:


MrRex free bet & sign up offer

If you want to get the best possible start to your life at a fresh bookmaker, MrRex's welcome offer is perfect for you. A free bet is up for grabs, and there are no wagering requirements attached to this £10 free bet token! The offer works as follows:

Your stake from the free bet token will not be returned, but with no wagering needed for the winnings this won't be an issue. The free bet must be used with minimum odds of 4/5, and it's not available for Skrill, Skrill 1-tap, Neteller or PayPal first deposits.

The Mr Rex free bet sign up offer comes with a 14 day expiry, which is longer than is the case on some of the other betting sites out there.

It was simple enough to claim the Mr Rex free bet sign up offer - just click through Bojoko's link.

As long as users make sure they have opted in to claim the Mr Rex welcome bonus, the free bet will be awarded once a user's qualifying bet has been settled by the sportsbook.

Users do not have to abide by any unusual conditions when claiming the welcome bonus at Mr Rex, while there are no wagering requirements on any of the winnings they may collect either.

Free bet no deposit

MrRex doesn't offer no deposit bonuses or free bets at the moment.

First deposit bonus code

You don't need a bonus code to claim MrRex's first deposit bonus.

Significant terms and conditions

Full terms and apply.

In terms of odds, MrRex offers players a solid return for their money. The average payout of the bookmaker is 93%, but significantly higher returns can be found in many sports and leagues.

Chief in these are the largest football leagues like the English Premier League, along with many other more followed sports and series. Lesser returns can be expected in more exotic and less followed sports, which is generally the case at most bookmakers.

MrRex offers odds in three different formats. You can change the odds display in the settings.

Mr Rex has odds that are in line with most other new sports betting sites in the UK.

Football fans will probably be reasonably satisfied with the decent prices at Mr Rex, but for some other big sports the site is lagging behind the very best value odds that are available.

Mr Rex also lacks the regular price boosts and enhanced odds deals that rival sportsbooks will typically use in order to make their odds look more appealing to customers.

MrRex doesn't have the most experience in the industry, but this hasn't slowed them down from providing a vast selection of 27 different kinds of sports to bet on right from the start. All UK bettors' favourites are present and accounted for, including football's biggest leagues, horse racing, cricket, rugby, greyhounds and many others.

The font choice at Mr Rex is extremely unique, so be sure to check out if it's for you or not. There has been a lot of emphasis on the site for having as much useful information as possible visible at all times. Football is clearly the biggest focus of the bookie, since links to the major leagues can be found right at the top of the page.


Expert's review Jamie Smith

Sportsbook tested

Mr Rex is a fairly basic sportsbook, having been built on the familiar Aspire Global platform which is used for a lot of new sports betting sites in the UK.

Football is the main sport to bet on, with a typical Premier League game having around 350 different bets to pick from, which will be more than enough for most customers.

Esports are covered too, with Mr Rex users able to bet on League of Legends and more, while there are special markets for Oscars fans and elections markets for people who like politics.

Unlike some other new sports betting sites in the UK, Mr Rex has both horse racing and greyhounds covered to a decent degree, but there is no virtual sport on offer here yet.

Minor sports like handball and water polo have some markets on offer at Mr Rex, but there is not a great deal of choice when it comes to cricket or golf betting, which is a shame.

Cashout is in place at Mr Rex and works in the same way as on most betting sites. It seems to be in place for most major live markets, but the offers made are not the most generous.

If you've ever been in a situation where your bet is winning, but you have a sinking feeling that the situation is about to change, MrRex's cash out feature is just the cure you need! By using the cashout you can ensure that your bet is going to be a winning one even before the match has ended.

The cash out amount available will always correlate with the likelihood of your bet winning, except of course the odds that you can get via cashout will always be slightly smaller.

In-play betting is more popular than ever, which is why MrRex has made it one of their priorities to provide a just as thorough live betting section on their site as with pre match bets. The site's unique look continues into the in-play as well, with a lot of betting options to be found on each match.

Usually there's about at least a dozen different ways to bet on a live event, and markets can be found through the in-play around the clock.


Expert's review Jamie Smith

Sportsbook tested

The Aspire Global platform that provides the foundation for Mr Rex is not great for live in-play betting, with high profile ongoing sporting events not always the easiest to find.

This can make a big difference when trying to get a live bet on in a limited amount of time. Each bet also needs to be authorised by the Mr Rex system, which can take a frustrating period too.

There are plenty of live in-play markets to pick from for most sports on this site and odds are fine, but one of the things missing from the in-play interface is the fact it has no live streams.

At Mr Rex, cashout is also not particularly easy to find because the site uses the Aspire Global platform which has a weakness when it comes to live betting.

Mr Rex customers who want to cashout will also have to wait for the request to be authorised, whereas at rival online betting sites the process is now fully automated and automatic.

There is also no option for Mr Rex customers to select a partial cashout for their bets either.

Mr Rex is a modern bookmaker, and knows that players need to be able to place bets on all devices. Most bets today are done via smart phones compared to computers, which is why the site optimizes itself perfectly to all screen sizes.

No downloading of an app is required to bet at Mr Rex, so you'll save space on your tablet or smart phone as well. Almost all services from the desktop version can also be enjoyed through your device's browser as well.

Mr Rex has a solid enough mobile site, which has a similar layout and design to the main site, but during testing I did get a bit frustrated with how slow some pages could be to load up.

Navigating between pre-match and live in-play markets is simple, while the My Bets area of the mobile site is where users will be able to find any of their bets that have cashout available.

Mr Rex does not currently have either an Android or iOS mobile app available to download.

Safe & responsible gambling

Gambling is supposed to be a form of entertainment, which is why MrRex is committed to preventing problematic gambling behaviour. If you or anyone you know is suffering from a gambling problem, seek immediate help. To limit these kinds of behaviour patterns, Mr Rex provides:

Mr Rex provides players with customer support in three different ways:

Live chat and email support can be enjoyed 08-00 CET, so only urgent issues in the middle of the night won't be solved within a couple of minutes.


Expert's review Jamie Smith

Sportsbook tested

As is the case with many other newer sports betting sites, Mr Rex does not have 24/7 cover.

The support team for the Mr Rex sportsbook is available seven days a week, but only from 08:00 CET to 00:00 CET.

Email customer support is available but most people will probably opt for the live chat option.

The live chat shows how long users should expect to wait for a reply and our testing found that responses were virtually instantaneous, with support staff friendly and able to help swiftly.

I had an issue with a free bet, with the agent quickly ensuring this was added to my account.

KYC & Documents

Operating in the UK means that a site needs to have a United Kingdom Gambling Commission license, and Mr Rex is no exception. This license guarantees the safety and security of the bookmaker completely, but also means that they need to know exactly who's playing on their site.

This means that the following documents can be asked from players:

All of these won't necessarily be asked of you even when making your first withdrawal, but if they are requested they must be sent. This can be done very easily through the site or customer service, but in general only a confirmation of identity is required.


Expert's review Jamie Smith

Sportsbook tested

Setting up a Mr Rex account was simple, with email verification all that was needed to get up and running on the sportsbook.

There was no need to upload any identification documents to make a first withdrawal at Mr Rex.

However, I spoke to customer support and they did mention that ID documentation would need to be uploaded at some point, although no timescale was offered for when this was needed.

Documents can be uploaded via a special section at Mr Rex's site, negating the need to email.

Users are asked to upload a copy of ID like a passport or driving licence, as well as proof of their address via a bank statement or a recent utility bill - mobile phone bills are not accepted.

Mr Rex customers might also need to verify the payment method they have used at some point.


There is plenty on offer when it comes to payment methods at MrRex for both deposits and withdrawals. Traditional methods are all covered, along with a few more niche choices, like AstroPay and Paysafecard. The minimum deposit you can make to the bookie is £10.

Withdrawals can usually be completed within a few days, while with faster methods like e-wallets winnings can often be enjoyed within the same day.


Expert's review Jamie Smith

Sportsbook tested

Depositing into an account on the Mr Rex sportsbook site was quick and easy, with a decent range of different payment methods to pick from.

As well as the standard debit cards from Visa and MasterCard - as is the case elsewhere, credit cards cannot be used - Mr Rex customers can opt to make a deposit using a bank transfer.

Other options include the likes of PayPal, Trustly, Skrill and Neteller, but using an e-wallet to make an initial deposit at Mr Rex may mean users cannot claim the site's welcome bonus. Mr Rex has not yet joined the list of sportsbooks allowing pay by phone bill, or crypto like Bitcoin.

The main thing to point out about payment methods at Mr Rex is the 2.5% deposit fee, which will certainly put some people off from choosing to bet with this new UK sportsbook site.

A similar fee is also charged on withdrawals, meaning that players will not receive 100 per cent of their winnings if they opt to bet at Mr Rex. Strangely, the site would not allow me to withdraw every penny I had in my account, only to the next £1 down, leaving a mere 37 pence remaining.

Withdrawing winnings via the card I used to make a deposit on signing up at Mr Rex took just four hours, which is pretty quick for that payment method, but the fee charged is a sour note.
