When you play with your bonus money, you have a wagering requirement that has to be fulfilled before any bonus money is converted into cash that you can withdraw.
To read more about how wagering requirement works please go here.
You can, of course, see the status of your wagering under the section “Active Bonuses”.
Once the bonus has been converted, you should be able to make a withdrawal providing the amount is above our minimum withdrawal amount of £30 (or the equivalent amount in other currencies).
