I have found recent;y that i also have a +1,3k satoshis bonus. dunno where this bonus is?
You need to play the Multiply BTC game and qualify certain minimum wagered to get bonuses.
But its too hard to get their bonus, my experience is too bad in getting their bonuses always loose all the balance in my freebitcoin even they share some their trick but it wont work for me that is why i stop playing in their multiply bitcoin but i do not stop claiming in their free roll.
Same here every time i have earned in free bitcoin i roll it on dice but i did not experience to i always lose. So i stop to play dice and i still claiming free bitcoin everyday. That is my another way to earn bitcoin for now.
