From all the threads I have read over at BW the second and third bonuses do not appear in the system. They are automatically credited to you after you clear the raked hands.
My first bonus was credited right away. I have now played 1700 raked hands for the second part of the bonus and the money has not been given to to me. I have emailed them repeatedly and I keep gettin the same auto response that tells me nothing but what I already know. Im about to send them 20 or so emails that are all the same. Maybe they will give me what I want.
I think that you need to wait 24hrs after clearing the 1,000 raked hands bonus before clearing the 1,500 hands bonus, so if you played any of those hands within 24 hours of getting your first $100 they won't be counted..
