The non-sticky bonus sounds tricky, how does the user know if they are gambling with their own money or with the bonus money?
And what if a user makes a deposit, then claims the bonus, and then withdrawal his money? Is that posible or we can withdrawal only after finish the bonus wagering?
My experience with bonuses like this is that they are either removed proportionately to the withdrawal amount or you forfeit them entirely when you withdraw.
After wagering the bonus, all money transferred to the real account is available for withdrawal.
