About
MrRex is an online casino at mrrex.com, launched in 2021 and operating as a whitelabel site. The site claims to offer over 2,500 games including slots, live dealer tables, and standard table games, with mobile access available without an app download. Payment options listed on the site include Visa, Skrill, Neteller, and PayPal.
The casino holds a UKGC-issued licence through its operator and is covered by an active casino licence granted on 1 November 2014. But the regulatory record attached to this brand is a concern. The operator behind MrRex was fined £1 million in May 2025 after the UK Gambling Commission found breaches of anti-money laundering rules and social responsibility code provisions. That fine also came with a formal warning and an additional licence condition requiring a third-party audit of the operator's practices.
With a Trustpilot rating of 2.2 out of 5 from 27 reviews and a domain that lacks basic technical security protections, MrRex doesn't present a strong picture of consumer confidence. Prospective players should weigh the operator's recent enforcement record carefully before signing up.

Welcome Offers
New players at MrRex can claim a deposit bonus that matches a percentage of their first deposit, up to a set maximum. There's one welcome offer available.
Conditions Explained
This is a deposit match bonus, meaning MrRex adds bonus funds on top of what you deposit. To withdraw that bonus money, you'll need to meet a wagering requirement, which means betting the bonus amount 10 times over before any withdrawal is possible. The bonus and any winnings from it expire after 30 days if not used. There's also a conversion cap, so the most you can withdraw from bonus winnings is equal to the original bonus amount received. Deposits made via Skrill or Neteller don't qualify. MrRex is part of a network of sites, and this offer is limited to five brands across that network, so if you've already claimed it elsewhere in the group, you won't be eligible. Requesting a withdrawal cancels any active or pending bonuses.
Ongoing Promotions
Existing players have two recurring promotions to choose from: a daily Mystery Box offer running Monday to Thursday that can award free spins, and a weekly free spins offer available from Thursday through Wednesday using a deposit code.
SWEET25Conditions Explained
Both promotions require opting in and depositing with a promo code. The Mystery Box runs Monday to Thursday and can be claimed once per day, with a minimum deposit of £20 required. Any winnings from free spins must be wagered 10 times within 7 days before withdrawal. The Mystery Box itself is only valid for 24 hours, while free spins from it last 7 days. The weekly free spins offer uses the code SWEET25 and can be used up to three times, running from Thursday through Wednesday. Both offers cap withdrawals at £20 regardless of how much you win from the free spins. Skrill and Neteller deposits are excluded from both promotions, and withdrawing cancels any active bonuses.

What Users Say
MrRex has a Trustpilot score of 2.2 out of 5 from 27 reviews. That sits well below average and suggests most reviewers have had a poor experience with the casino.
Common Themes
No detailed topic summaries are available for MrRex specifically. The overall low rating points to dissatisfaction across the user base, but the review volume is small enough that individual experiences may vary significantly.
Regulatory Context
The operator's May 2025 enforcement action specifically cited social responsibility failures alongside AML breaches. Social responsibility obligations include player protection measures such as affordability checks and intervention on problem gambling. Low Trustpilot scores often accompany complaints about account restrictions or withdrawal issues, which can sometimes reflect those same compliance processes. Without detailed review breakdowns for MrRex, a direct link can't be drawn, but the enforcement context is worth noting for anyone experiencing problems with their account.

UKGC Licence Status
MrRex operates under licences held by ProgressPlay Limited (UKGC account number 39335). The operator holds three active UKGC licences: a Remote Casino licence granted on 1 November 2014, which covers online slots and table games; a General Betting Standard (Real Event) licence granted on 17 December 2018, permitting fixed-odds sports betting; and a Bingo licence granted on 23 August 2024.
ProgressPlay Limited is registered with three Alternative Dispute Resolution providers: eCOGRA, IBAS, and Resolver. ADR registration means consumers who can't resolve a complaint directly with the casino have the right to escalate to an independent body for a binding decision.
Regulatory Actions
ProgressPlay Limited, the operator behind MrRex, has one recorded enforcement action. On 9 May 2025, the UK Gambling Commission imposed a £1,000,000 financial penalty after finding breaches of anti-money laundering code provisions and social responsibility requirements. The Commission also issued a formal warning and attached an additional licence condition requiring the operator to commission a third-party audit of its compliance practices.
Site Assessment
Licensed Operator
MrRex is licensed through ProgressPlay Limited, which has held a UKGC licence since 1 November 2014 — over 11 years of continuous licensing. The operator runs a mixed portfolio of casino and sports betting brands, of which MrRex is one. Despite the length of its licence history, ProgressPlay Limited received a significant regulatory penalty in 2025. That enforcement action dropped its trust grade to F, and the attached audit condition means the operator remains under heightened UKGC scrutiny.
Other Sites by ProgressPlay Limited
ProgressPlay Limited operates a large portfolio of whitelabel casino and sports betting sites under the same UKGC licence. Other active brands on the same operator account include 777Tigers, Aced Bet, Ace Lucky Casino, BetElite, Betmorph Casino, BetStorm, and Booming Casino, among others.
