i hadn't collected my 100% bonus (but i just did).
how could $200 be the bonus rollover requirement over a quantity of $20?
They just do tricks like that. They give you free money ( bonus) and you can gamble with it. But if you win, they dont allow to withdraw your bonus money and winnings from it , they want you to play this bonus money thru 3 times or 5 times and with certain minimum odds requirement also( usually it is @1.5, sometimes 1.7 and I have even seen requirement @2.0)
Lets say you have 20 bucks bonus money and they require to play it thru 3 times before you can withdraw it. Minimum odds 1.5. So you chose from card bet with 1.5 odds( or more) and put 20 bucks bonus on it. You win and now you have 30 dollars bonus money.
You still cant withdraw it, you have to bet again. Lets say you put 20 bucks on @2.0 odds and win it again. Now you have 50 buck bonus and you played it thru 2 times.You put 20 on odds 1.8 and lose it . Now you have 30 bucks bonus left, but it becomes usual withdrawable money, you played your initial bonus thru 3 times as was requirement.
Of course you can bet with less stakes if you want, but in this case it takes longer to play it thru 3 times. Usually people are using this bonus money to make risky underdog bets ( it is free after all, if you lose it you didnt lose YOUR money)
