No one can win on this site, Who would give you BTC for free! NEVER!. It is a java site, and you will lose at the end you are Guaranteed by they win-loss ratio. Unless you are earning referrals credits, individually you will never claim enough for withdrawal , whose minimumm is 30,000 satoshies. It would take you a year or so - rewards keeps on declining as you claim and each claim takes an hour - so at most you can do 12 in a day or you stay up the whole day, and that is an impossibility.
I used the site for months, and most times do multiple - works good first ten or so rolls at 60/50 , if you do not stop , you will lose.
I also place lottery thousands of satoshies and never worn anything.
