I don't like gambling but I thought I'd try out a casino offer at Captain Cooks casino. All you do is deposit money claim your bonus and then play for a few hours.
I can play Black jack (minutes to learn.. about an hour to master.. lol).I know the house advantage is less than 1% so you can expect to win about half the bonus.
At CC's I got confused about the T&C.. this is what happened
1] deposited $200 then claimed my $50 bonus
2] emailed support to clear up what I had to do to win the bonus There was no reply
3] Three emails later and nothing. So I withdrew my $200.( I did try to withdraw the lot but it wouldn't let me

)
4] What can I do with the bonus $50?? Well I played three hands of BJ with it and it went down to $48.. Np- It was dead money anyway!
5]Methinks - I'm bored of BJ I'll go all-in (yeah, yeah wrong terminology..)Any way I double up to nearly $98 in one hand.
6) Still can't touch it because you need to play 3000 hands..
7) On CC's they have an Autoplay feature.I.e you set it up with your strategy and it plays all your hands..
8) I set the autoplay going:3000 hands later I returned to find that my $98 had turned into $164

9) Somewhat bemused as I'd just bet a load of money that wasn't mine I tried to cashout the lot - bonus and all...
10) I just got an email- I opened it expecting to be banned (I could live with that as I officially hate BJ now) to find out they had just dumped $164 in my Neteller account.....
Maybe I should give up poker....
