Context for United Kingdom: Since 19 January 2026 the Gambling Commission has capped wagering requirements at 10x the bonus (Social Responsibility Code 5.1.1), and promotions may no longer combine product types such as sports and casino in one offer. If a bonus on this page states 35x, 50x or higher, that figure predates the cap or does not reflect the operator's current UK terms - check the live terms on site, and treat any UK offer still advertising above 10x with caution.
Here is the current MrRex welcome offer for players in United Kingdom. Bonus terms change and are set by MrRex for each market — always confirm the live offer on its own site. See every licensed betting site in United Kingdom →
