basically, if you accept this bonus you have a certain amout of days to clear it. By clearing it, it means that you have to earn FTP's by playing the real $ ring games, sng's and tournys. doesnt matter which you play as long as your getting some FTP's. After you earn a certain amount of points you will get a portion of that $50 bonus put into your BR. For example - the $100 bonus. every FTP you earn will unlock 6cents of the $100. once you earn enough points till you unlock $10 of the $100. then the $10 will go into your BR and you have to start working on unlocking another $10 to get creditted again. After you accept the bonus, you can go to the - Cashier --> Bonus Account - in there you can see how many points you will have to earn to get some money.
Sorry this was kind of scatterd lol, but hope it gives you a little idea of how it works. GL
