Freebitco.in gives up to almost 1 btc depends on the btc price but the chances are small. I dont think the chances are really 1 in 10.000 tho because the site is really popular and a lot of people is using it so they would have to give 1 btc almost every day if the chances were really like that even tho they claim to be provably fair. The faucet is one of the best anyways since they pay high, kind of.
