MrRex overview

MrRex is a new entry to the UK market, having launched in late 2021. It's a casino-first brand but that doesn't detract from its excellent sports betting offering powered by Aspire Global. The MrRex site has a relaxed feel to it but with BtoBet supplying its tech wizardry to the sportsbook you can be sure you're using a quality product.

Ongoing MrRex Customer Promotions

MrRex provides plenty of daily and weekly offers for players, whether they are using the sportsbook or the casino. Check out a handful of the standout offers available to ongoing customers and remember that the site constantly updates its promotional page on a regular basis, introducing new promotions each week.

MrRex Loyalty Points / Reward Store

Players signing up and playing on MrRex automatically participate in the Loyalty Points scheme. Every game played receives rewards points based on game type and size of the wager with points also awarded when making deposits, placing bets and playing certain casino games.

To add an incentivised angle to the service, MrRex provides “missions” to players. These missions once completed, usually reward players with further bonus points and can be based on reaching depositing goals, playing a specific type of game, or even achieving a bonus function on a particular featured slot.

MrRex offers a great bonus scheme, rewarding loyal players with great rewards

To further gamify the rewards system, players can find themselves ranking on leaderboards, rising through a levelling system and receiving achievement badges, leading to further rewards and improved promotions.

The points earned by a player can also be redeemed against various rewards that are featured in the “reward shop”, with free spins, bonus funds, better deposit bonuses and improved cashback deals all offered within

No matter how you play, MrRex offers players the chance to earn rewards each time they play, which is a great feature.

    Betting Features At MrRex Sportsbook

    MrRex sportsbook offers a more concise service compared to some of the other larger betting sites, but what features can customers expect when placing bets on sports?


    MrRex sportsbook offers a very good cash-out feature, that works with all pre-match bets, no matter the sporting event. Players can simply go into their bets and use the cash-out feature to take an early win.

    One major plus point for MrRex is that cash-out is available on the vast majority of in-play markets too.

    In-Play Betting

    MrRex sportsbook offers a solid In-play betting experience, with plenty of markets available, depending on the sporting event. Football and tennis tend to dominate in terms of most markets, but players have the opportunity to bet on everything from esports to ice hockey in-play and with that aforementioned cash-out available too.

    Partial Cash-Out

    MrRex sportsbook also offers partial cash-out to players, a great extra feature for players looking to free up potential winnings for another betting market.

    If your selection is winning, you can click the cash-out button and via a pop-up slider, select the amount you wish to cash out and how much of the potential winnings you wish to leave on the current bet.

    How Good Are The MrRex Website/Apps To Use?

    • Website

    MrRex is owned by Progress Play and has a familiar, tried and tested layout to the site, however, a minor refresh has made the site a lot better to use overall.

    • Navigation

    Once logged in, players are greeted with a promotional offer which can be a little obtrusive, but with a brief scroll, players are then taken to the sportsbook, which features current live events to bet upon.

    A menu on the left side hosts plenty of player options, including account management, cashier options, rewards bonuses and customer support. This can be minimised to help the user experience too.

    • Betting

    On the betting screen, logos for individual sports can be expanded to show more detail or kept out of the way, which again is a nice option to have. Sports are split between live and pre-match sections, with players able to dig down deeper, thanks to drop-down menus for each sport.

    Placing a bet was straightforward, with bet selections appearing instantly on the bet slip, while a drop-down menu on the slip offers single, multiple, system and chain bet types, depending on the number of selections made.

    Overall, the site ran very smoothly and is a marked improvement on previous Progress Play iterations, which could be a little cumbersome and slow to use. Here, the user experience is quick, snappy and without issue.

    Mr Rex on desktop

    MrRex runs well on desktop, since a recent update.

    • Mobile App

    MrRex like other Progress Play sites does not have a dedicated app on either iOS or Android, however, thanks to the recent update to the layout of the site, its functionality via a mobile browser is much better than it was previously.

    • Navigation

    There is little difference in terms of menu and options, with quick access to player account options, casino games and the cashier too. The response times are much better too, compared to its previous incarnation, although there is still the odd delay in populating the page, although this could be something that irons itself out, with time.

    • Betting

    Placing a bet is initially less intuitive, as once a player has made a selection, the betslip appears at the end of all available markets within that match.

    So for instance, if a game has 200 markets, players will need to scroll through all markets after making a selection, to get to their betslip. Not ideal, but certainly something that could be changed going forward.

    In general, the mobile site has taken a positive step forward and is a much better experience than it used to be, prior to the update.

    Mr Rex mobile

    Live Streaming / Virtual Feed

    • Watching Sports

    As with other Progress Play websites, MrRex does not play host to any live streaming of sporting events at all, which is a shame and something that could be a deal breaker for some.

    Those looking for live sports streams can use bet365 or Betway for their live-action needs if that is a major requirement.

    • Live Feed

    MrRex does provide live feeds of games, with a very basic, animated pitch and enough stats to give players an idea of how the game is panning out. 

    For more in-depth coverage of live games, the likes of betfair or bet365 offer a better option, with more detailed visualisation, let alone actual live streams.

    Mr Rex livefeed

    MrRex's live feed is simple but effective enough for users.

    How Is The MrRex Betting Experience?

    The MrRex sportsbook is a very good option for players looking for a solid sports betting experience. It plays host to around 3000 markets across sporting and non-sporting events, including football, tennis, basketball and rugby among many others. Let's take a look at how the sports book functions.

    Navigation is relatively straightforward, with sports divided between live and pre-match options, while individual sports have a series of sub-menus that help players find exactly what they are looking for.

    A dashboard feature highlights the big upcoming games of the day, along with current live action, while players can use a simple search feature to target a competition, team or player for potential markets.

    Extras such as a sporting diary and results centre are welcome features, providing further information to players, without having to leave the site.

    Picking selections and making bets is straightforward, with choices added to the bet slip on the right-hand side, while a drop-down menu on the betslip, offers single, multiple, system and chain bet options, depending on the number of selections chosen.

    Horse Racing Betting

    For racing fans, the selection is pretty poor, with Progress Play continuing to not support UK & Irish betting markets on their UK-based websites. The lack of options expands worldwide, with only racing in the USA actually covered in any form.

    Available markets for each race, cover win, place, forecast and tricast, along with system bets, but the inability to take ante-post prices only adds to the disappointment.

    Once again, the decision to have a UK sportsbook without UK & Irish racing is a baffling one and is a detriment to a very good site, otherwise.

    Football Betting

    When it comes to football betting, MrRex Sportsbook is a great place to play, with over 100 competitions and leagues around the world covered.

    Although it is easy to find the big matches of the day, searching for smaller contests can be a little more challenging thanks to the drop-down menu system that is in place, but overall, if a game exists, it can usually be found on the MrRex Sportsbook.

    Matches from popular markets such as the Premier League or La Liga have over 400+ markets available per match, including fan favourites such as First To Score and Correct Score, through to Asian Handicap markets.

    MrRex doesn’t host the popular bet builder option, but selections can still be added into an accumulator selection, while combo bets (team to win and over/under) are available, so there are plenty of options for players despite the lack of bet builder.

    All matches feature in-play markets, although the amount available can fluctuate depending on how popular the game will likely be. So a Premier League game will have more in-play options than a Finnish reserve match for instance.

    More minor leagues overall tend to have much fewer markets available, but all games have cash-out and partial cash-out options, along with in-play cash-out too, which is a great feature in my opinion.

    MrRex Sportsbook offers a very strong and dedicated football betting experience.

    Esports And Other Markets

    MrRex offers good betting coverage of esports events, covering around ten games, including Call Of Duty, League Of Legends, Starcraft 2, e-Football and DOTA 2.

    Outright markets and individual map/round results can be bet upon, along with some handicap markets, dependent on the event itself.

    MrRex likes to provide odds for more obscure sports, with surfing and pesapallo among the rarer commodities on offer from a sporting perspective.

    Away from sports, MrRex provides some attractive alternatives, with political markets, which usually cover elections around the globe, alongside specialised TV and film markets too, with the likes of BBC Spoty, the next James Bond and the winner of the Italian reality show, L’isloa dei Famosi available at the time of this review.

    What is The Payout Margin At MrRex Sportsbook

    MrRex offers a comprehensive sportsbook offering, with plenty of markets and features, but how does it compare, when it comes to the payout margin, against its peers?

    Using a midweek Champions League fixture as a reference, I calculated and compared the margin on a three-way market, to see where MrRex ranks in comparison to other sites.

    BookmakerPayout Margin

    Sky Bet

    Rhino Bet



    As seen in the above table, MrRex sportsbook fares poorly amongst its peers for payouts, sitting over 5% below Sky Bet in this instance. Even with fluctuating prices taken into consideration, this is quite disappointing and should be factored in, when looking to join MrRex.

    Does MrRex Have Casino Games?

    Yes!MrRex, like many sports betting sites, does feature a comprehensive casino offering, which provides well over 1500 games in total, across slot, table and live games. Check out what's on offer at MrRex casino below.

    • Slots

    MrRex casino hosts a huge 1200+ slot titles in total, including plenty of favourites, such as Starburst, Slashimi, Reel King, Gonzo’s Quest and plenty more.

    Progressive jackpots feature heavily at MrRex casino too, with over 75 jackpot games to play and big prizes to be won. These jackpots are linked across Progress Play’s suite of betting and casino sites, with players from any of those, capable of winning a major prize.

    MrRex does not have exclusive slot titles but regularly pushes popular games via its featured section, along with plenty of focus aimed at newer games too, to encourage players to try different options.

    • Scratch and Other Games

    A casual games section focuses on scratch games mainly, along with instant bingo and pachinko variants. There are over 130 games to choose from and some feature big prize amounts, including Scratch Gold which has a £300,000 jackpot!

    As is the case with Progress Play casino sites, all slots and casual games can be played in demo modes, which is a great way to try a new game and understand any game mechanics, without risking real-world funds.

    Mr Rex Slots list

    MrRex casino features over 1200 slot game!

    • Table Games

    In terms of table games, the range available is limited compared to its slot offerings, with around 25 or more options, covering all the regulars, such as Blackjack, Roulette and Baccarat, along with solitaire and poker options.

    The majority of games can be played at low stakes, with a minimum wager of 20p available on Roulette, which is great for low-level players, who do not want to risk their funds with high stakes.

    Although the number of table games is far from ideal, it does seem to follow the precedent of casino sites focusing more on live casino offerings and slots of late.

    Mr Rex casino games list

    There are around 25 table games to play at MrRex casino

    • Live Casino

    Live casino options at MrRex casino are a little underwhelming compared to other sites, with just 15 live games available to players in total, with all the games provided by Evolution Gaming.

    Games such as Baccarat, Roulette, Craps and Blackjack are all available, but compared to 32red, which offers around 50 titles to play, it is a very minimal collection of titles.

    To make matters worse, a lack of “gameshow” options is very noticeable, with only Dream Catcher, as the standout title, while popular games such as Monopoly Live and Ginzi’s Treasure Hunt are notable for their absence. 

    In general, the live casino options at MrRex casino are disappointing.

    Who Provides The Games At MrRex

    Games at MrRex casino are provided by some of the best game manufacturers around, including:

    • Progress Play

    What Payment Methods Are Available?

    • Deposits

    The following payment options are available to use for deposits to MrRex.

    Visa, Mastercard, Maestro, JCB, Solo, Switch, Diners Club, Discover, Paypal, Paysafecard, Much Better, ecoPayz, Neteller, Skrill, Neosurf and Payviaphone

    It should be noted that depositing bonuses are forfeited when depositing with Neteller and Skrill.

    The following payment options have a minimum deposit amount:

    Payment MethodMinimum Deposit
    Much Better, ecoPayz, Neteller, Skrill£20


    £10 + 15% processing fee

    More information can be found at the MrRex website.

    Some Payment Methods Do Not Qualify For Deposit Bonuses

    Deposits with Neteller or Skrill, will automatically forfeit any potential bonus promotions that would have been applicable when using another payment type.

    • Withdrawals

    The following payment options allow for withdrawals to be made.

    Visa, Mastercard, Maestro, JCB, Solo, Switch, Diners Club, Discover, Paypal Paysafecard, Much Better, ecoPayz, Neteller, Skrill and Neosurf

    It is not possible to withdraw money using Payviaphone.

    Withdrawals can take between 1-6 days to process, which is slower than more established sites such as Leo Vegas or betfair.

    Unfortunately, all withdrawals are subject to a 1% processing fee, to a maximum of £3:00. This is partly down to MrRex using a third party to process payments and passing on the fees to the player.

    Players need to consider this when making withdrawals to their account, as continuous small withdrawals will eventually add up to a significant amount.

    How Good Is The Customer Service?

    MrRex has three levels of help and assistance available. Firstly, a help guide is available, which houses all frequently asked questions, which is a handy option for new members, while at the bottom of the site, there are further help guides, discussing payment methods and more.

    If that information isn’t enough, players can use the available web chat, which is open between 8:00 am and midnight, seven days a week. Ideally, this assistance would be 24/7 but it is a small issue overall.

    For further inquiries, contact can also be made via email, if required.

    Having tested all contact options, I am pleased to say that the web chat is relatively quick to access and my inquiries were answered in a timely and professional manner, whilst the email response I received was helpful and provided the information I requested, although it could have been a little quicker.
