So, if your bonus is £50 and the stated wagering requirements are 10x, you need to place £500 worth of wagers with that bonus money, before being able to withdraw winnings won with your bonus funds. The maximum of 10x is now binding under UK Gambling Commission rules. The casino bonuses you will see in the list at the top of this page are for new customers only, but online casino sites do also have existing customer promotions.
