I am also wondering how freebitcoin is still around while giving away huge amount of prizes every now and then. Freebitcoin was there when I started bitcoin and it's one of the faucet sites I've been at the beginning.
Right now, tons of prizes and events has been added on it such as the Wheel of Fortune which is also free for everyone. Except for the gambling part of the website, there's ton of rewards which free users can enjoy. For me, seeing that wheel spins as it goes by those huge rewards, I feel excitement and hope that somehow it'll land on it. Unfortunately, I've been winning small rewards and as of now my biggest win is this and I'm satisfied with it.
