I am using freebitco.in since couple of years and trying to roll almost every day. But never won something big. I spent more than what i earned from free roll or multi. Spent few dollars on jackpot. But either its my luck or i have got bad client seed every time. ~
1385 rolls is a very small amount for somebody that has been active for two years. It would be very surprising if you had actually won something big with such few rolls. The amount spent on jackpots does seem substantial but without any context it is hard to evaluate just how unlucky you were in this regard. If you were aiming for the bigger jackpots then it did not take many rolls to reach this amount and it would be completely expected that you have not won a big prize.
The chance of hitting the jackpot is really low but you can get it quickly if you are lucky enough. I have tried to get the jackpot too but the luck wasn't on my side. I got the 8888 roll number while I wasn't playing for the jackpots. And I have made almost 18k hourly faucet roll till now but never won anything from the top three faucet payout. Anyway, try to get 10k satoshi jackpot prize in first few thousands roll. Spend for for bigger prize if you don't hit it within 15k-20k rolls.
