If you are unsure of what wagering is, take a note of how much "real" money you have in account, for example you may have £35 in your account... £20 of which is real and withdrawable, £15 is bonus funds... so, pick a slot or game and gamble the £15.... once your balance goes down to £20 you STOP as you have then bust out and any further gamble is with your real money.. Hope that helps
