All Bingo sites are the same all rip off any deposit you make you get a bonus which you cannot withdraw the prize money is so low you can never hope to reach a withdraw limit. I once won £125 on a free bonus at a bingo site playing slots I couldn't withdraw as i had not deposited so i thought well I might as well deposit and withdraw so I deposited £25 went to withdraw. "sorry you haven't reached the turnover required to withdraw".
I had to keep playing to get anywhere near withdrawing I reached the turnover with only £45 left so I thought best withdraw you haven't lost anything then, clicked withdraw "sorry the miminum withdraw is £50." So stumped again I played to try to get to £50 and guess what lost it all.
If you play bingo sites do it for fun not to win anything.
