Hi guys ~
Just throwing my 2 cents worth in and hoping it may help you.
I have never known any casino to not expect some certain amount of playthrough before you cash out -- right or wrong of them -- UNLESS.....(and here is the catch that WE can finally use, instead of them).....If you write them an email and keep a copy of it for yourself, telling them to put you on their "NO BONUS LIST", then you can cash out any time you please......whether you are winning or losing!
Personally, I like to use their bonus money to try out several of their games and see how they pay off. Then, when the bonus money is gone, if I am not pretty far ahead, I write that email!
I learned about this from communicating to and from many support people and managers at many casinos.
You might not like doing things that way, and to each his own. I am only saying that it always works out best for ME, so that when I win some money, I know that money is MY profit! With the email on record, they cannot argue with you.
Best of luck to you always!
