Born in 2021, Mr Rex is an infant in the online casino world, but don’t let that fool you, this place has a lot of potential. Operating on the Aspire Global platform, this casino has access to its vast range of games from providers such as Microgaming, NetEnt and Evolution, to name a few. Expect to see slots, jackpots, table games and more. There’s even a sportsbook for all you sporty types!

A very well designed site. Mr Rex’s colour combos of vibrant orange, white and black really make it stand out. The site feels clean, modern and inviting. Mobile is where it really stands out, as you can tell Aspire has gone with a mobile-first approach. However, the desktop design is just as nice.

As with all Aspire Global casinos, the signup process is incredibly simple and completed in two steps. Be sure to have verification docs at hand, as you cannot make a deposit and play until verified. Don’t let this put you off, Mr. Rex has one of the fastest verification processes I’ve come across! It’s all done in under 2 mins.

My experience was somewhat tainted here due to problems I outline in the following sections. I can only assume that these are merely teething issues due to the site's relative infancy, especially as Aspire Global operates some great casinos. Hopefully, this is fixed soon (if not already!).

Overall rating:


Mr Rex welcomes all UK players with a great bonus package. You can get a total of £200 of bonus money and 100 free spins when you start playing on Mr Rex.

When you make your first deposit, you will get your first part of the bonus offer.

  • 1st deposit: 100% bonus up to £200

You can also get 100 free spins on your third deposit. If you make two more deposits of at least £20 each, you get 100 free spins with your third deposit.

Upon sign up, I was offered a very strong welcome bonus of 100% deposit match up to £200 + 100 bonus spins! The minimum deposit to claim this offer is £10 and carries a 35x wagering requirement. It is worth noting that you cannot claim this offer if making a deposit via Skrill or Neteller. This rule seems to be prevalent across all the Aspire Global casinos I have played at. There are a few things you should also know about the bonus spins:

  • A total of 3 deposits (including the 1st deposit) are required to unlock them.
  • A set number of spins will be added to your account with each deposit you make.
  • Each set of spins will expire after 24 hours.
  • Bonus spins also carry 35x wagering.

Unfortunately, my welcome bonus was not automatically credited to my account after I made a deposit of £40. Over 14 days passed before I finally reached out to support, who kindly credited my account with the £40 bonus and 20 spins on Starburst.

During my time playing at Mr Rex, I didn’t see many casino offers in the promotions section. Aside from the sportsbook and casino welcome offers, I came across just a few network promotions hosted by providers such as Microgaming. Personally, I’d like to see more options here. Especially as this is a dedicated promotions area.

The best place to find Mr Rex's promotional offers is via email. I cannot recommend enough that all new players should opt into email marketing. I received weekly (sometimes daily) CRM offers, including spin tournaments and deposit offers. Make sure to read the terms as not all wagering at Mr Rex is 35x. Some bonuses can run as high as 50x.

As you would expect from a casino that operates on the Aspire Global platform, there is a solid variety of games to choose from at Mr Rex. In fact, whilst I was playing, there were over 800 different games, including slots, table games and live casino. If you’re a sports fan, then you have already hit the jackpot as there is a sportsbook too!

Expect to see many big-name providers such as Microgaming, Play’n Go and Red Tiger amongst others. Live casino is supported by Evolution and Authentic Gaming, offering a range of classics, such as Roulette and Blackjack, as well as games like Monopoly Live.

I always appreciate a casino that makes an effort to be simple yet offers a lot, and this is exactly what Mr Rex has done. On desktop, you’ll find four main categories on the navigation bar that take you to Casino, Live Casino, Sportsbook and Promotions. Under each main category, there are clear sub-categories, making the process of finding something you like super easy. If you’re the kind of person who knows what they want, there is a great sized search bar that can pull up results very quick.

Unfortunately, from a UX perspective, things weren’t as good as they looked on the surface. When trying to navigate between core categories such as Casino and Live Casino, I found both desktop and mobile to experience lag. In some instances, I was even logged out when simply navigating! When I did make it to the live casino (on mobile), I tried playing Infinite Blackjack and was stuck on a blank screen before giving up entirely. Thankfully, I did have better luck with the slots on both devices. All the slots I tested opened quickly and had no issues.

You can tell that Mr Rex was designed with mobile-first in mind. Design-wise Mr Rex has got many of the little things I look out for on mobile locked down. From the extra-large game tile images to the simple navigation bar and clean UI. However, as mentioned above, this did not necessarily translate into an overly enjoyable mobile experience, at least not in my case.

It is worth mentioning that Mr Rex does not have a native app. Personally, I prefer using casino apps over mobile browsers, and I think Mr Rex would really benefit from having one.

Mr Rex makes it easy to locate their live support via the hamburger menu. Here there is a very comprehensive selection of predetermined questions and answers. These are categorised across all major pain points for players, from your account and technical to general and sports. I would definitely suggest searching here if you have a query that doesn’t require any human assistance.

If you need to speak with a CS agent, then the two options available are email and live chat. Unfortunately, I didn’t have the greatest experience accessing either at Mr Rex. Firstly, opening the live support area via desktop was literally impossible. It was clear that live support was only optimised for mobile, as opening it via desktop caused the site to crash. When I realised that mobile was the only way, I decided to email first to avoid any further site crashes. I never received a reply. After waiting over a week I decided to try live chat (via mobile of course). Thankfully, I received a swift response regarding my missing welcome bonus. It had been over 2 weeks since I’d signed up, but the agent was kind enough to credit my account with the missing bonus.

Hopefully, the technical issues experienced with desktop were due to the casino’s relative infancy and is fixed soon!

Player safety and fair play are important to Mr Rex, which is why they need to make sure we know who their customers are, and that they are of legal age.

This is why they ask for verifications when you make a withdrawal. You can use the secure document uploader to send the required documents. These may include:

  • Proof of identity
  • Proof of address
  • Proof of deposit

If you need any help with the process, Mr Rex customer support is there to help you.

All new players at Mr Rex are required to submit verification documents upon registration. You will not be able to make a deposit until this information has been provided.

If you have signed up to other Aspire Global casinos, then you will be familiar with the verification process. Upon first login, an automatic pop-up appears, prompting players to upload two types of verification, proof of ID and address. This can be a passport or driver's licence, and a utility bill or bank statement.

I will give credit to the speed at which Mr Rex, and all other Aspire casinos, can verify these docs. I used a passport scan and a digital bank statement, both of which were uploaded and verified in under 2 mins. The whole process was completed in a matter of minutes, and before I knew it, I was funded and playing!

Depositing and withdrawing money is easy for UK punters. Mr Rex has multiple options available and you can pick the method that works the best for you.

Mr Rex has a good variety of deposit options available to players. At the time I played here six options include Visa, PayPal, Instant Banking, Trustly, MuchBetter and Paysafecard.

This wasn’t the first time I have deposited at an Aspire Global casino. So I wasn’t shocked when the 2.5% fee was applied to my deposit. However, this does not mean that I don’t believe it is outrageous to charge customers to play at your casino. Although the actual depositing process is swift, the fee really damages any credibility.

As with other Aspire casinos, if you have an available bonus when requesting a withdrawal, it will need to be manually cancelled. I’ve never liked this as it drags out the withdrawal process. Additionally, there is a clear intention to stop players from withdrawing their money which I feel is a bit dishonest.

The actual cashout process could be more streamlined, but overall it is good. Although not incredibly important, it’s worth noting that you can only withdraw to the nearest pound. Funds took under 48hrs to arrive back in my account.
