Sometimes I still use freebitco.in. They now also got a lottery but haven't never hit something there. Are here users who had luck with the lottery??
We were looking for someone who hit the main reward, but no one admitted;) There were few users that hit second and third reward. One time i hit jackpot (8888) in "Multiply".
From my experience I hit the one with a large amount of satoshi something like 80-90 thousand. I thought that can never happen but it did and it is an awesome feeling. It will boost you to not stop using their faucet.
